How does a balanced chemical equation verify the law of conservation of matter?

$\color {pink}\boxed{\colorbox{white} {✦Answer✦}}$

According to the Law conservation of matter

Mass can neither be created nor destroyed in a chemical reaction. That is, the total mass of the elements present in the products of a chemical reaction has to be equal to the total mass of the elements present in the reactants. In other words, the number of atoms of each element remains the same, before and after a chemical reaction. Hence, we need to balance the skeletal chemical equation.

Which conclusion can be made from Gay-Lussac's law? (1 point)

MrRa [10]

The answer to the question <u>Which conclusion can be made from Gay-Lussac's law</u> is For a constant volume, the pressure of a gas is directly proportional to the temperature in Kelvin

Gay-Lussac's law shows the relationship between the pressure of a fixed mass of gas and its temperature in Kelvin.

It states that for a constant volume, the pressure of a gas is directly proportional to the temperature in Kelvin.

Mathematically, P ∝ T

P = kT

$\frac{P}{T} = k$

$\frac{P_{1} }{T_{1} } = \frac{P_{2} }{T_{2} }$

So, the answer to the question <u>Which conclusion can be made from Gay-Lussac's law</u> is For a constant volume, the pressure of a gas is directly proportional to the temperature in Kelvin

How many grams of water are produced from the reaction of 40.3 g of oxygen according to this equation? 2h2(g) + o2(g) → 2h2o(g)?

Vikki [24]

The balanced equation for the above reaction is as follows;
2H₂ + O₂ --> 2H₂O
stoichiometry of O₂ to H₂O is 1:2
number of O₂ moles reacted - 40.3 g / 32 g/mol = 1.26 mol
according to molar ratio
number of water moles produced = 2 x number of O₂ moles reacted
number of water moles formed - 1.26 x 2 = 2.52 mol
mass of water produced = 2.52 mol x 18 g/mol = 45.4 g
45.4 g of water produced
