Answer:
The new pressure is 0,469 atm
Explanation:
We apply Boyle Mariotte's Law: for a given mass of gas at constant temperature, its pressure and volume vary inversely proportionally (the higher the pressure, the lower the volume and vice versa):
P1 x V1 = P2 xV2 We solve P2:
P2 = (P1 x V1)/V2
P2= (0,410 atm x 32 L) / 28 L
<em>P2= 0,469 atm</em>
Answer:
0.98 g of H₂
Explanation:
the balanced equation for the reaction is
Mg + 2HCl ---> MgCl₂ + H₂
molar ratio of Mg to H₂ is 1:1
number of Mg moles reacted = 12 g/ 24.3 g/mol = 0.49 mol
according to molar ratio
when 1 mol of Mg reacts 1 mol of H₂ is formed
therefore when 0.49 mol of Mg reacts - 0.49 mol of H₂ forms
therefore mass of H₂ formed = 0.49 mol x 2 g/mol = 0.98 g
mass of H₂ formed is 0.98 g

The movement of liquids and gases is generally referred to as a flow,” A concept that describes how fluids behave and how they interact with their surrounding environment .
