Answers

Answer 1

Answer: A decrease in population due to health threats is a possible consequence of decreasing air quality resulting from global warming.

Explanation:

When average temperature of Earth keeps on increasing for a longer period of time due to greenhouse gases, increased level of carbon dioxide and other gases etc then it is called global warming.

As humans use oxygen to sustain which is present in the air. So, when there will occur decrease in air quality that results from global warming then it means more illness or diseases will be there.

Hence, people will tend to die more often because of decrease in the air quality their health is getting affected.

Thus, we can conclude that a decrease in population due to health threats is a possible consequence of decreasing air quality resulting from global warming.

Iron reacts with copper (I) sulfate to produce copper and iron (II) sulfate. If 4.32x10^25
particles of copper (I) sulfate react, how many moles of copper will be produced?
Fe + Cu2504 --> FeSO4 + 2Cu

Answers

Answer: 143.48 moles of copper will be produced.

Explanation:

We are given:

Number of particles of copper (I) sulfate = [tex]4.32\times 10^{25}[/tex]

According to the mole concept:

[tex]6.022\times 10^{23}[/tex] number of particles is contained in 1 mole of a compound

So, [tex]4.32\times 10^{25}[/tex] number of particles will be contained in = [tex]\frac{1}{6.022\times 10^{23}}\times 4.32\times 10^{25}=71.74mol[/tex] of copper (I) sulfate

The given chemical equation follows:

[tex]Fe+Cu_2SO_4\rightarrow FeSO_4+2Cu[/tex]

By the stoichiometry of the reaction:

If 1 mole of copper (I) sulfate produces 2 moles of Cu

So, 71.74 moles of copper (I) sulfate will produce = [tex]\frac{2}{1}\times 71.74=143.48mol[/tex] of Cu

Hence, 143.48 moles of copper will be produced.

Suppose that you chose sodium carbonate to precipitate the chromium ions from a solution of chromium (III) chloride. Write and balance the equation of this double-displacement reaction.

If the solution has a volume of 520 mL and the concentration of chromium (III) chloride is 0.224 M, how many grams of sodium carbonate should you add to the solution to precipitate out all the chromium ions?

Answers

Answer:

18.5g Na2CO3

Explanation:

Chromium (III) chloride, CrCl3, reacts with Na2CO3 as follows:

2CrCl3 + 3Na2CO3 → Cr2(CO3)3(s) + 6NaCl

Where 2 moles of CrCl3 react with 3 moles of Na2CO3 to produce 1 mole of Cr2(CO3)3 -The precipitate-

To solve this question we need to find the moles of CrCl3 added. With the chemical equation we can find the moles of Na2CO3 and its mass as follows:

Moles CrCl3:

520mL = 0.520L * (0.224mol/L) = 0.116 moles CrCl3

Moles Na2CO3:

0.116 moles CrCl3 * (3 mol Na2CO3 / 2mol CrCl3) = 0.175 moles Na2CO3

Mass Na2CO3 -Molar mass: 105.99g/mol-

0.175 moles Na2CO3 * (105.99g/mol) = 18.5g Na2CO3

_______organisma consist of only one cell and _________ organisms consist of many cells​

Answers

Answer:

Unicellular organisms consist of only one cell and multicellular organisms consist of many cell.

Explanation:

Living things made up of a cell are called unicellular beings. They are very small and simple. In other words, unicellular organisms are those that are formed only by a single cell in which all the vital functions necessary for life are produced. For this reason, they are mostly microscopic organisms. Examples of unicellular organisms are viruses or bacteria.

Multicellular organisms are made up of a large number of cells. They present, therefore, a greater complexity than unicellular organisms in terms of the functions they develop. All current multicellular organisms come from a single cell, that is, they begin their life being unicellular. That is, they are formed from a zygote. Some examples of multicellular organisms are mammals, fungi, and mosses.

So, unicellular organisms consist of only one cell and multicellular organisms consist of many cell.

The DNA and RNA are polynucleotides which contain a chain of nucleotides monomers with different nitrogenous bases. Each  nucleotide different from the others, as  It has different bases. The correct option is A.

What is a nucleotide?

A nucleotide is defined as a compound containing three component units, namely a pentose sugar (either ribose or 2-deoxyribose), a heterocyclic nitrogenous base (a substituted purine or a substituted pyrimidine) and a phosphate group.

The nucleotides are the phosphate esters of nucleosides. A nucleotide containing ribose as the sugar unit is termed as the ribonucleotide. While one containing 2-deoxyribose as the sugar unit is termed as the deoxyribonucleotide.

The nitrogenous bases in RNA are adenine, guanine, cytosine and uracil whereas in DNA the bases are adenine, guanine, cytosine and thymine. The purines are adenine and guanine whereas cytosine, thymine and uracil are pyrimidines.

Thus the correct option is A.

Boiling the solution causes the equilibrium in the following reaction to shift to the ________. HCO3- H3O --> H2CO3 H2O

Answers

Answer:

Right

Explanation:

The reaction of bicarbonate ion with acid is shown in the following equation;

HCO3- + H3O --> H2CO3 + H2O

This reaction is endothermic. This implies that energy must be absorbed from the surrounding as the reaction progresses.

Hence, when the solution is boiled, energy is supplied to the system in the form of heat and the forward reaction is favoured hence the equilibrium shifts to the right.

what is a saturted solution

Answers

Answer:

Please find the definition and further explanation below

Explanation:

Based on the ability for the solvent (liquid substance) to dissolve a solute (solid substance), a solution can either be unsaturated, saturated or supersaturated. A SATURATED SOLUTION is that which contains the maximum amount of solute a solvent can possibly dissolve.

In other words, a saturated solution can no longer dissolve anymore solute, and hence, any further solute added forms crystals or makes the solution supersaturated.

Answers

Answer:

-In an closed-end manometer, the gas pressure is equal to the difference in column heights in the two arms of a U tube.

-In an open-end manometer, the gas pressure pushes on the Hg surface on one arm of the U tube and atmospheric pressure gas pushes on the other.

-The gas pressure is directly related to the height of a column of mercury it produces in a U tube.

Explanation:

Manometer is simply an instrument used for measuring the pressure that is acting on a column of liquid.

Now they could either be open ended or closed ended manometers.

However the difference between both of them is that;

Closed - end manometer are those used to measure absolute pressure while open end manometer is used to measure the gauge pressure.

From operation of a closed end manometer, the gas pressure is read from the difference in column heights of the two arms of the U tube being used. While in open end thermometer, the gas pressure will push the mercury surface on one arm of the U tube while the atmospheric pressure gas will push on the other arm.

Lastly, the height of a column of mercury in the U-tube is directly related to the gas pressure.

Thus, the correct options are A, D, E

Answer:

1. How many ATOMS of boron are present in 2.20 moles of boron trifluoride? atoms of boron.

2. How many MOLES of fluorine are present in  of boron trifluoride? moles of fluorine.​

Explanation:

The molecular formula of boron trifluoride is [tex]BF_3[/tex].

So, one mole of boron trifluoride has one mole of boron atoms.

1. The number of boron atoms in 2.20 moles of boron trifluoride is 2.20 moles.

The number of atoms in 2.20 moles of boron is:

One mole of boron has ---- [tex]6.023x10^2^3[/tex] atoms.

Then, 2.20 moles of boron has

-[tex]=2.20 mol. x 6.023 x 10^2^3 atoms /1 mol\\=13.25x10^2^3 atoms[/tex]

2. Calculate the number of moles of BF3 in 5.35*1022 molecules.

[tex](5.35x10^2^2 molecules/6.023x10^2^3)x 1mol\\=0.0888mol[/tex]

One mole of boron trifluoride has three moles of fluorine atoms.

Hence, 0.0888moles of BF3 has 3x0.0888mol of fluorine atoms.

=0.266mol of fluorine atoms.

Methane is the main component of natural gas. Using the given reaction enthalpy, calculate the heat energy produced by the combustion of one kilogram of methane.

Answers

Answer: The heat energy produced is 53831.25KJ

Explanation:

METHANE is the main component of natural gas. It can undergo combustion reaction in air with a bright blue flame to produce carbondioxide and water. The heat of reaction (enthalpy) is negative because heat is absorbed during the chemical reaction. To calculate the heat energy produced by the combustion of one kilogram (1 kg) of methane the following steps are taken:

Molecular mass of methane =16 gm/mol.

So moles of 1 kg methane =

Given mass of methane ÷ molecular weight of methane

But the given mass = 1kg = 1000g

Therefore,

moles of 1000g methane = 1000÷16

= 62.5 moles

Hence, energy evolved = (moles of methane) × (heat of combustion)

Therefore,

heat energy produced= 62.5 × (-861.3kj)

= -53831.25kj

The heat energy produced by the combustion of one kilogram of methane is –53831.25 KJ

We'll begin by calculating the number of mole in 1 Kg of CH₄

Mass of CH₄ = 1 kg = 1000 g

Molar mass of CH₄ = 12 + (4×1) = 16 g/mol

Mole of CH₄ =?

Mole = mass /molar mass

Mole of CH₄ = 1000 / 16

Mole = 62.5 moles

Finally, we shall determine the heat energy produced from the reaction.

CH₄ + 2O₂ —> CO₂ + 2H₂O ΔH = –861.3 KJ

From the balanced equation above,

1 mole of CH₄ reacted to produce –861.3 KJ.

Therefore,

62.5 moles of CH₄ will react to produce = 62.5 × –861.3 = –53831.25 KJ

Thus, –53831.25 KJ of heat energy is produced.
