why is it important that the level of the sea water does not go above the level of the filter paper
Answers
Answer:
The water (the substance) that passes through the filter paper is called the filtrate. If your mixture is a solution, such as salty water, then filtering will not separate the salt from the water. Instead, by heating the soluton the solvent (water) evaporates leaving the solid (salt) behind.

if you had a block square that weighed 5.00 grams what would be the length of each side
Answers
Answer:
[tex]l = 0.793[/tex] cm
Explanation:
Let us assume the density of block square [tex]10[/tex] g/cm³
As we know
Volume = [tex]\frac{Mass}{Density}[/tex]
Thus Volume of this block is equal to [tex]\frac{5}{10} = 0.5[/tex]
As we know volume of square block of side of length "l" is equal to [tex]l^3[/tex]
[tex]l^3 = 0.5[/tex]
[tex]l = 0.793[/tex] cm

What is the charge of an electron?
Answers
Calculate the volume, at STP, of a 0.950 g sample of Carbon Monoxide gas, CO.
Answers
Answer:
0.76L is the pressure of CO at STP
Explanation:
To solve this question we must use combined gas law:
PV = nRT
Where P is the pressure of the gas (1atm at STP)
V is volume (Our incognite)
n are moles of the gas (0.950g * (1mol/28g) = 0.034 moles
R is gas constant (0.082atmL/molK)
T is absolute temperature (273.15K at STP)
V = nRT/P
V = 0.034mol*0.082atmL/molK*273.15K / 1atm
V = 0.76L is the pressure of CO at STP

B. H2 + H2 + O2® H2O + H2O
C. 2H2 + O2® H2O
D. 4H2 + 2O2® 4H2O
Answers
Answer:
C
Explanation
On the reactants side there is 4 Hydrogen atoms in total and two oxygen atoms on the left however on the right there is two hydrogen atoms and one oxygen atom. Leaving this equation unbalanced
The equation that is NOT balanced is [tex]\rm 2H_2 + O_2\rightarrow H_2O[/tex]. The correct answer is option C.
In a balanced chemical equation, the number of atoms of each element on the reactant side must be equal to the number of atoms of each element on the product side.
In equation A, there are 4 hydrogen atoms and 2 oxygen atoms on both the reactant and product sides, so it is balanced.In equation B, there are 4 hydrogen atoms and 2 oxygen atoms on both the reactant and product sides, so it is balanced.In equation C, there are 4 hydrogen atoms and 2 oxygen atoms on the reactant side, but only 2 hydrogen atoms and 1 oxygen atoms on the product side. Therefore, it is not balanced.In equation D, there are 8 hydrogen atoms and 4 oxygen atoms on both the reactant and product sides, so it is balanced.In conclusion, equation C. [tex]\rm 2H_2 + O_2\rightarrow H_2O[/tex] is the one that is NOT balanced. It has an unequal number of oxygen atoms on the reactant and product sides.

Answer:
CO2 molar mass=44.01g

CO2 molar mass = 12.01+2(16.00)=44.01g
3 moles CO2 * (44.01 g CO2)/(1 mol CO2)=132.03g

what do igneous rocks become when they break down and settle into layers?
Answers
Answer:
Sedimentary rocks
Explanation:
Igneous rocks will become sedimentary rocks when they break down and settle into layers .
Igneous rocks are rocks that are formed by the cooling and solidification of magma within or on the earth crust.
When agents of weathering and denudation forces acts on a rock body, they break them down producing sediments in the process.
Sediments are transported into depositional basins where they are laid down and cemented together. This in turn forms sedimentary rocks. The break down and settling of sediments leads to the formation of sedimentary rocks.when an ecosystem changes the results are (positive negative both or none) explain

What is the chemical formula for sodium sulfate
Answers
Answer:
Na2So4

Sulphate’s formula is SO4 2-,
because sulphate has double the charge of Na, you need two Na’s to make it equal.
Therefore it’s Na2SO4
For species that reproduce asexually, all their offspring are
A. genetically identical
B. genetically different
C. almost identical
D. slightly different
Answers
Answer:
A. genetically identical
Explanation:
Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. A single individual can produce offspring asexually and large numbers of offspring can be produced quickly
All the offspring that are produced in the process are genetically identical.
When we talk about this mode of reproduction, we talk about a mode of reproduction in which an organism reproduces without the fusion of gametes. This occurs essentially by cell division.
When this occur, there is no crossing of genetic material as such, all the offspring that are produced in the process are genetically identical.

A 2.5 L container holds a sample of hydrogen gas at 291 K and 180 kPa.
If the pressure increases to 350 kPa and the volume remains constant, what will the new temperature be?
Round your answer to one decimal place.
Answers
Answer:
The new temperature will be 565.83 K.
Explanation:
Gay Lussac's law establishes the relationship between the temperature and the pressure of a gas when the volume is constant. This law says that the pressure of the gas is directly proportional to its temperature. This means that if the temperature increases, the pressure will increase; or if the temperature decreases, the pressure will decrease.
In other words, Gay-Lussac's law states that when a gas undergoes a constant volume transformation, the ratio of the pressure exerted by the gas temperature remains constant:
[tex]\frac{P}{T} =k[/tex]
When an ideal gas goes from a state 1 to a state 2, it is true:
[tex]\frac{P1}{T1} =\frac{P2}{T2}[/tex]
In this case:
P1= 180 kPaT1= 291 KP2= 350 kPaT2= ?Replacing:
[tex]\frac{180 kPa}{291 K} =\frac{350 kPa}{T2}[/tex]
Solving:
[tex]T2=350 kPa*\frac{291 K}{180 kPa}[/tex]
T2= 565.83 K
The new temperature will be 565.83 K.

Answers
Answer:
From my side the correct option is "A"
Explanation: Reasons for its correction are ,
1) Highly reactive: Nanoparticles are therefore extremely unstable and easily change themselves or react with active substances to reach a relatively stable state in some cases. This causes desired changes or undesired changes to nanoparticles and thus makes them exhibit a high reactivity and a poor stability.
2)Small size: Nanotechnology can provide rapid and sensitive detection of cancer-related molecules, enabling scientists to detect molecular changes even when they occur only in a small percentage of cells. Nanotechnology also has the potential to generate entirely novel and highly effective therapeutic agents.
