Answer:

1.5moles of S;

Explanation:

The reaction expression is given as:

            S +  O₂   →   SO₂

Number of moles of SO₂  = 1.5moles

From the balanced reaction expression:

              1 mole of SO₂ will be produced from 1 mole of S;

  So;      1.5moles of SO₂  will produce 1.5moles of S;

The moles of S₂ needed to produce 1.50 moles of SO₂ gas is 1.5 mol.

The mole is a SI unit of measurement that is used to calculate the quantity of any substance.

The reaction is

S +  O₂   →   SO₂

The number of moles of SO₂ is 1.50 mol

1 mole of S produce 1 mole of SO₂

Then, 1.5 mole of S will produce 1.5 SO₂

Thus, the moles are 1.5.

Answer:

No

Explanation:

There are no interactive forces (i.e., attraction or repulsion) between the particles of a gas.

The average kinetic energy of gas particles is proportional to the absolute temperature of the gas, and all gases at the same temperature have the same average kinetic energy.

Answer: Why don't we feel the air pressing on us all the time?

Explanation:

Because air is a fluid, the weight of the air is transmitted to the palm of your hand and to the back of your hand at the same time. These forces cancel so that your hand overall feels no net force

Answer:the gravity in the atmosphere is pulling all the air so we can survive

Answer:

77460 g

Explanation:

To solve this problem first we convert molecules into moles, using Avogadro's number:

3.47x10²⁶ molecules ÷ 6.023x10²³ molecules/mol = 576.12 moles

Then we convert 576.12 CuCl₂ moles into grams, using its molar mass:

576.12 mol * 134.45 g/mol = 77460 g

So the answer is 77460 g, or 77.46 kg.

Answer:

Calculate he number of moles you have by taking the Mass / molar mass. if you have 1000 grams ; then 1,000 g / 151.001 g/mol = X g moles. Then multiply by Avogadros # = 6.022140857 × 10^23 molecules per g mole. The result is the # of molecules of MnSO4.

Answer:

Go to your periodic table and look for each element. Find the mass for Aluminum, Nitrogen, Oxygen, and Hydrogen.

After you find those, for each compound you must add them together and find the least amount of sig figs after the decimal point.

For the first compound, Al(NO3)3, you will have a total of

1 Aluminum atom

3 Nitrogen atoms

9 Oxygen atoms

Aluminum has 26.982 g/mol

Nitrogen has 14.007 g/mol

Oxygen has 15.999 g/mol

Now multiply those numbers by the amount of atoms of each element.

(1)26.982 g/mol = 26.982 g/mol

(3)14.007 g/mol = 42.021 g/mol

(9)15.999 g/mol = 143.991 g/mol

now add all of those numbers together, and you see that their least significant figure after the decimal is 3, so round to 3 digits after the decimal point.

26.983 + 42.021 + 143.991 = 212.994

now do the same for the other compound

to start you off.. you have

6 Hydrogen atoms

3 Oxygen atoms

Hydrogen has 1.009 g/mol

Oxygen has 15.999 g/mol

the least significant figure after the decimal point is 3, so round you 3 digits after the decimal point.

after you finish getting your totals, you. until them and find the greatest sig fig over all. comment on this if you need further instruction :)

According to the stoichiometry of the given chemical equation, 1.45 g of Cl₂ are needed to produce 2.4 grams of NaCl.

Stoichiometry is the determination of proportions of elements or compounds in a chemical reaction. The related relations are based on law of conservation of mass and law of combining weights and volumes.

Stoichiometry is used in quantitative analysis for measuring concentrations of substances present in the sample.

According to the given chemical equation, 70.906 g of chlorine gives 117 g sodium chloride, thus, 2.4 g of sodium chloride will be produced, when 2.4×70.906/117= 1.45 g of Cl₂ reacts.

Thus, according to the stoichiometry of the given chemical equation, 1.45 g of Cl₂ are needed to produce 2.4 grams of NaCl.
