The law of conservation of mass is applicable to

Chemistry
1 answer:
katrin2010 [14]3 years ago
3 0

Answer:

The law of conservation of mass states that in a closed system, mass is neither created nor destroyed during a chemical or physical reaction. The law of conservation of mass is applied whenever you balance a chemical equation.

Explanation:

According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

The law of conservation of mass is useful for a number of calculations and can be used to solve for unknown masses, such the amount of gas consumed or produced during a reaction.

It is applicable in a chemical when the the mass of the products in a chemical reaction is equal to  the mass of the reactants.

But it is not applicable in a nuclear fusion as some of the mass is generated as energy.

Please help me with some extra details please
mojhsa [17]

Answer:

Empirical Formula: Al_2O_3

Explanation:

Since total mass is 306, we have:

Mass of $Al = \frac{52.9}{100}\times 306=161.87 $

Mass of $O= \frac{47.1}{100}\times 306=144.126$

Hence,

Moles of $Al=\frac{Mass}{molar mass}=\frac{161.87}{27}=6$

Moles of $O= \frac{Mass}{molar mass}=\frac{144.126}{16}=9$

Hence the formula is $Al_6O_9$ , or, $Al_2O_3$

A compound that contains both potassium and oxygen formed when potassium metal was burned in oxygen gas. the mass of the compoun
Artemon [7]
Answer:
             3.2 g of O₂

Solution:
             This reaction is for the formation of Potassium Superoxide, The reaction is as follow,

                                           K  +  O₂     →     KO₂

First let us confirm that either the given amount of Potassium produces the given amount of Potassium oxide or not,
So,
As,
                39.098 g (1 mole) K produced  =  71.098 g of K₂O
So,
                          3.91 g of K will produce  =  X g of K₂O

Solving for X,
                      X  =  (3.91 g × 71.098 g) ÷ 39.098

                      X  =  7.11 g of K₂O

Hence, it is confirmed that we have selected the right equation,
So,
As,
                     39.098 g of K required  =  32 g of O₂
So,
                     3.91 g of K will require  =  X g of O₂

Solving for X,
                     X  =  (3.91 g × 32 g) ÷ 39.098 g

                     X  =  3.2 g of O₂
