i need help pls this isnt chemistry btw i just couldnt find science so i had to put that

Answer:

7.5mols of S

Explanation:

just make sure your equation is balanced, and in this case it's balanced,

so now you can do more to more ratio.

so in this case we are dealing with SO2 and S.

According to our balanced equation we have 1 mol of SO2 producing 3mols of S, i.e

1mol(SO2). : 3mols(S)

we've been asked that if we use 2.5 moles of SO2, how many moles of S will be produced?

So, this is how we can determine the number of moles of S that will be produced .

SO2 : S

1mol : 3mols(S)

2.5mols: x

we cross multiply

x=2.5×3

x=7.5mols of S.

.: if we use 2.5 mols of SO2,, 7.5mols of Sulfur will be produced

Answer:

Elctromagnetic waves can travel through empty space.

Explanation:

Waves that may pass through matter or empty space are known as electromagnetic waves. The electromagnetic field, like the other basic fields, penetrates the whole universe, including the region we refer to as empty space. There are no fields in space. The medium through which electromagnetic waves travel is called the electromagnetic field.

Explanation:

Assuming the quantity of current passing through the zinc and copper electrolytes is the same, mass of Zinc deposited is (x/64) × 65.0 g.

Electrolysis is the decomposition of a substance known as an electrolyte when electric current is passed through its solution or molten form.

The mass of an electrolyte deposited when current is passed is dependent on the current and the charge on the ion.

In the electrolysis of copper and zinc, assuming the quantity of current passed through their solution are the same, the moles of each zinc and copper deposited will be the same since the charges on their ions are the same.

Assuming x g of copper is deposited.

molar mass of copper = 64.0 g

molar mass of Zinc = 65.0 g

moles of copper deposited = x/64

moles of zinc deposited = x/64

mass of Zinc deposited = (x/64) × 65.0 g

Therefore, the mass of Zinc deposited is (x/64) × 65.0 g.

Explanation:

The equilibrium constant is the relation between the products and the reactants of the reaction. The K, for the reaction, is 172.

The equilibrium constant (K) is the relationship in the form of a ratio that denotes the concentration of the products to the reactants in a reaction.

The balanced chemical reaction is shown as,

[tex]\rm N_{2}(g) + 3H_{2}(g) \leftrightharpoons 2NH_{3}(g)[/tex]

Given,

Concentration of nitrogen =0.521 M

Concentration of hydrogen = 0.482 M

Concentration of ammonia = 3.17 M

The value of K is calculated  as:

[tex]\begin{aligned} \rm K &= \rm \dfrac{[NH_{3}]^{2}}{[N_{2}][H_{2}]^3}\\\\&= \dfrac{(3.17)^{2}}{(0.521)(0.482)^{3}}\\\\&= 172\end{aligned}[/tex]

Therefore, the equilibrium constant for the reaction is 172.

The molecular mass of the gas if 200 mL of gas weighs 0.344 grams at STP is 38.53g/mol. Details on how to calculate molecular mass can be found below.

The molecular mass of a gas can be calculated by using the following expression:

Molecular weight of the gas = mass × volume at STP (22.4L)/ volume of gas

= 0.344 × 22.4/0.2

= 7.7056/0.2

= 38.53g/mol

Therefore, the molecular mass of the gas if 200 mL of gas weighs 0.344 grams at STP is 38.53g/mol.

Answer:

1.48×10²⁴ Cu atoms

Explanation:

For this question you need to use Avogadro's number 6.022×10²³atoms.

2.45 moles of Cu ×[tex]\frac{6.022x10x^{23} atoms }{1 mole}[/tex]= 1.47539×10²⁴ atoms.

The moles cancel out so you are left with atoms.

Since there are 3 significant figures in the question there should be 3 significant figures in your answer, which is 1.48×10²⁴ Cu atoms.
