Why does the chemical reaction seen here obey the law of conservation of matter?

<u><em>Answer:</em></u>

Because there are the same number of atoms of each element shown on both sides

<u><em>Explanation</em></u>

As in chemical reactions, atoms bonds are break and new bonds are formed. As new substance are formed but overall they have same elements, no new elements come from outside or go to outside. In other words , rearrangement of atoms take place but number of atoms remained same.

NaOH + HCl -----> NaCl + H2O

As in above reaction there are the same number of atoms of each element shown on both sides .

A sample of air has a volume of 140 mL 0.980 atm. At what pressure will its final volume be 50.0 mL at constant temperature?

bogdanovich [222]

Answer:

The new pressure is 2, 74 atm

Explanation:

We apply Boyle Mariotte's law, where for a given mass of gas at constant temperature, the pressure and volume vary inversely proportionally: P1xV1 = P2xV2 P2=( P1 x V1)/V2 1 L-----1000L--->( 140ml/1000ml)x1L=0,140 L

(50ml/1000ml)x 1L =0,050L

P2= (0,980 atm x 0,140 L)/0,050L= 2, 744 atm
