Answer:

7.5 g of hydrogen gas reacts with 50.0 g oxygen gas to form 57.5 g of water.

Explanation:

Here we have the check if the mass of the reactants is equal to the mass of the products.

Reactants

$7.5+50=57.5\ \text{g}$

Products

$57.5\ \text{g}$

The data is consistent with the law of conservation of matter.

Reactants

$50+243=293\ \text{g}$

Products

$206+97=303\ \text{g}$

The data is not consistent with the law of conservation of matter.

Reactant

$17.7+34.7=52.4\ \text{g}$

Products

$62.4\ \text{g}$

The data is not consistent with the law of conservation of matter.

Only the first data is consistent with the law of conservation of matter.

At 45.2 L cylinder containing C2H2F4 at a pressure of 3.00 atm is connected by the valve to 4060 mL cylinder containing N2H4 at

puteri [66]

The partial pressure of the N2H4 gas is 1.50 atm.

<h3>Dalton's law of partial pressure</h3>

From the Dalton's law of partial pressure, the total pressure of a mixture of gases is the sum of the individual partial pressures of all the gases present in the mixture.

We have the following;

C2H2F4 = 3.00 atm

N2H4 = c

Total pressure = 3.00 atm + 1.50 atm = 4.50 atm

Hence, the partial pressure of the N2H4 is N2H4.

Answer:

Yes, the formed product is calcium nitride, $Ca_3N_2$ .

Explanation:

Hello,

In this case, the answer is yes, since nitrogen in gaseous state is able to react with calcium in solid state to form calcium nitride as shown below:

$N_2+Ca\rightarrow Ca_3N_2$

This is possible since calcium losses two electrons and nitrogen gains three electrons to remain positively and negatively charged respectively, forming the aforementioned ionic compound.

Best regards.
