what is the mass of 7.525 x10^24 particles of sulfur difluoride SF2?

Answers

Answer:

Mass will be equal to 874.56 gram

Explanation:

Molar mass of sulfur = 32 u

Molar mass of Florine = 19 u

Therefore molar mass of [tex]SF_2[/tex] [tex]=32+2\times 19=70u[/tex]

So mass of [tex]6.023\times 10^{23}[/tex] particle is 70 gram

Therefore mass of 1 particle

[tex]=\frac{70}{6.023\times 10^{23}}=11.62\times 10^{-23}g[/tex]

Therefore mass of [tex]7.525\times 10^{24}[/tex] particle is

[tex]7.525\times 10^{24}\times 11.62\times 10^{-23}=874.56gram[/tex]

Sulfuric acid (H2SO4) has a molar mass of 98.1 g/mol. How many oxygen atoms are found in 75.0 g of H2SO4? A. 1.15 × 10^23 B. 1.84 × 10^24 C. 4.61 × 10^23 D. 7.87 × 10^23

Answers

Answer:

B

Explanation:

first find the no. Of moles of H2SO4

=  75/98.1

= 0.7645

Next step

In on mole of H2SO4 the no.of oxygen atom is 4.

1 H2SO4 : 4 O

0.7645  : x                     x= 0.7645x4= 3.0581

next multiply avogadros constant

3.0581 x 6.022× 10^23 =1.84x10^24

Mass present in 1 gram of mole substance is called molar mass. Molar mass is calculated by: dividing the mass of the compound in grams by the number of moles present in the substances.

The correct answer is:

option B. 1.84 × 10²⁴

Given,

The mass of sulfuric acid =75.0 g

The molar mass of sulfuric acid = 98.1 g/mol

1.The moles of sulfuric acid can be calculated by

M = m ÷ n

where M is molar mass, m is mass and n moles.

moles of sulfuric acid = mass ÷ molar mass

= 75 g ÷ 98.1 g/mol  

=0.7645 moles

Hence moles of sulfuric acid present is 0.7645 moles.

2. 1 mole of sulfuric acid = 4 oxygen atoms.

Then, 0.7645 moles of sulfuric will contain: 0.7645 × 4 = 3.0581 atoms of oxygen

3. Oxygen atoms present in 75.0 g of H₂SO₄ will be calculated by multiplying it with Avogadro's constant:

= 3.0581 x 6.022× 10²³

= 1.84x10²⁴

Therefore, 1.84 × 10²⁴ oxygen atoms will be found in 75.0 g of H₂SO₄.

Which of the following human activities can increase the risks of flooding?

Answers

deforestation i hope this helps

Answer:

Deforestation and Cultivation

Explanation:

First I am going to give the definition of deforestation:

Deforestation is basically the removal of trees.

The removal of trees leaves leaves very little vegetative cover to hold heavy rain fall. This is why mudslides and things happen. When the land is clear and flat, the water keeps on going instead of going into the soil. That water that keeps on going is called runoff water. If we planted trees by the rivers, that could take down the height of the floods in towns by 20%

At first I was going to say widening rivers, but that is a way to manage river water. When we lengthen the river, it is so that the water can take more time to reach the river canal.

Definition of Cultivation: The production of food by preparing the land to grow crops (especially on a large scale) animal husbandry - breeding and caring for farm animals. agriculture, tree farming - the cultivation of tree for the production of timber.

I was also going to say Cultivation. Over-cultivation is the excessive use of farmland to the point where productivity falls due to soil exhaustion or land degradation. Now this is actually why we have floods in the USA. The soil cannot soak up any water, therefore the water over flows and that is when a flood starts to happen.

I know this took some time but hope I could help :)

Explanation:

Explain the effects that different frequencies of electromagnetic radiation have when absorbed by matter.

Answers

In order to answer this question we might first want to think about what is electromagnetic radiation. In essence it’s light, just some of the wavelengths are too long or too short for us to see.

We can think about it as two oscillating sinusoidal (goes up and down) waves, one is electric, the other is magnetic.

Because we’re dealing in waves, that means we can calculate their frequency, wavelength, amplitude (brightness) and period.

To calculate it we can use E=hc/lambda
Where E = jewels of energy
h = Planck’s constant
c = speed of light
Lambda = wavelength

It doesn’t really matter for this question what those things mean, just note that it takes more energy to have a shorter wavelength, or less energy to have a longer wavelength.

So now we can answer the question. Light of a longer wavelength has less energy than that of a shorter wavelength. So, when long wavelengths are absorbed by matter (atoms) they will give those atoms less energy. So, either it will pass through the object entirely or it will make the atoms vibrate a little bit more than they already are and we call that thermal energy, or heat.

If high energy wavelengths are passing through matter then they will be giving those atoms a lot of energy, sometimes even ionizing the atoms.
Which, if you’re a living thing can be very bad for your cells.

I hope that helps.

As the frequency of the radiation increases further, into the visible light spectrum, it can cause electronic transitions in atoms and molecules, leading to the emission of light and other optical effects.

What is electromagnetic radiation?

Electromagnetic radiation is a form of energy that travels through space in the form of waves, without the need for a medium to propagate. It is characterized by oscillating electric and magnetic fields that are perpendicular to each other and the direction of propagation.

At low frequencies, such as radio waves and microwaves, the radiation typically only causes heating of the matter, as it transfers energy to the molecules in the material.

At higher frequencies, such as infrared radiation, the radiation can cause vibrations in the atoms and molecules of matter, leading to heating and thermal effects.

Thus, When matter absorbs electromagnetic radiation, the effects that it has on the matter depend on the frequency of the radiation.

A student wants to determine whether an unknown solid is an ionic compound. He puts some in water and finds that it does not dissolve. He says that this proves the solid is ionic. Which best evaluates the student's reasoning?

A. He is incorrect, because water can dissolve ionic solids.
B. The test proves nothing, because water dissolves all solids.
C. He is correct, because polar liquids cannot dissolve ionic solids.
D. The test proves nothing, because it only shows that the solid is a compound.

(I know water is polar, so I think its a?)

Answers

The student cannot prove that if the compound is ionic or covalent because not all ionic compounds dissolves in water. Some ionic compounds have higher lattice energy results in lower solubility. Thus, option D could be correct.

What are ionic compounds?

Ionic compounds are formed between metals and non metals. Metals are electron rich and they easily donate electrons to the non-metals. Non-metals are generally electronegative and they easily gains electrons from the metals.

Donating electrons make metals acquire positive charge and the non-metals acquire a  negative charge. This charge separation make the compound possess a permanent dipole moment. Which make them easily soluble in water by ion-dipole interaction.

However, some ionic compounds have very strong ionic bonds and their binding energy will be greater so that cannot be easily dissolved in water. For example, AgCl. Therefore, we cannot predict weather the compound is ionic or not by simply noting it solubility in water.

Cuando se queman combustibles que tienen algún compuesto de azufre se produce dióxido de azufre (SO2), un gas irritante que puede provocar lluvia ácida. En el análisis del aire de una ciudad se ha encontrado una concentración de SO2 de 14 mg/m^3 ¿Qué cantidad de SO2 habrá en 1 L de aire?

Answers

Answer:

See answer below

Explanation:

I have to answer this question in english because is the rule here. I hope you can understand this.

Now, in order to answer this, is really easy. We already have the quantity of SO₂ in the air of a city. This concentration is 14 mg/m³, so we want to know the quantity in 1 L. This quantity can be expressed in mass.

If concentration according to the units is: mg/m³ This means that we have units of mass and volume. So, in order to know the quantity of SO₂ in mass, we need to convert the units of volume m³ to liter.

1 m³ is covered in 1000 L, therefore:

14 mg/m³ * 1 m³/1000 L = 0.014 mg/L

Then, the mass will be:

m = 0.014 mg/L * 1 L

m = 0.014 mg of SO₂

This is the quantity of SO₂ in 1 L.
