30 g of hydrogen reacts with 120 g of oxygen to form water.How much water is produced?
Rus_ich [418]

According to law of conservation of mass.

In a chemical reaction Mass is neither created nor destroyed.

  • Mass of product =Mass of reactant

#1

Mass of water

\\ \sf\longmapsto 30+120=150g

#2

Mass of sulphur:-

\\ \sf\longmapsto 136.9-111.6=25.3g

A gas has a volume of 45.0 mL and a pressure of .98 atm. If the pressure increased to 2.1 atm and the temperature remained the s
goblinko [34]

Answer: The new volume is 95.45 mL.

Explanation:

Given: V_{1} = 45.0 mL,         P_{1} = 0.98 atm

P_{2} = 2.1 atm,               V_{2} = ?

According to Boyle's law, at constant temperature the pressure of a gas is inversely proportional to its volume.

Therefore, formula used to calculate the new volume is as follows.

\frac{P_{1}}{V_{1}} = \frac{P_{2}}{V_{2}}

Substitute the values into above formula as follows.

\frac{P_{1}}{V_{1}} = \frac{P_{2}}{V_{2}}\\\frac{0.98 atm}{45.0 mL} = \frac{2.1 atm}{V_{2}}\\V_{2} = 95.45 mL

Thus, we can conclude that the new volume is 95.45 mL.
