Answer:
0.067 mole Ag°
Explanation:
Given 7.22 g Ag° = 7.22g Ag/ 107.8g/mol = 0.0670 mole Ag° (3 sig. figs.)
Answer:
pressure that is exerted by one gas as if it occupied a container by itself. Explanation:
Answer:C
Explanation: Because the hot air is less dense than the surrounding air
Mass of water required = 64.42 g
<h3>Further explanation</h3>
Given
Reaction
6CO2 + 6H2O → C6H12O6 + 6O2
157.35 g CO2
Required
mass of water
Solution
mol CO₂ = mass : MW CO₂
mol CO₂ = 157.35 g : 44.01 g/mol
mol CO₂ = 3.575
From the equation, mol ratio CO₂ : H₂O = 6 : 6, so mol H₂O = mol CO₂=3.575
Mass H₂O = mol x MW H₂O
mass H₂O = 3.575 x 18.02
mass H₂O = 64.42 g
Answer:
It gets its identity from tiny particles: positively charged protons in the nucleus, balanced by negatively charged electrons all around, plus neutrons, which have no charge at all.
