Answer:
Explanation:
Sucrose Is Made up of Glucose and Fructose
Glucose is a simple sugar or monosaccharide.
Fructose, or “fruit sugar,” is a monosaccharide like glucose
The balanced equation:
2 H₂ + O₂ → 2 H₂O
moles of Hydrogen = mass of hydrogen ÷ molar mass of hydrogen
= 45.7 g ÷ 2 g/mol
= 22.85 mol
Now, the mole ratio of O₂ : H₂ is 1 : 2
which means that there are two times as much moles of H₂ as O₂ taking
part in the reaction
Thus since moles of H₂ = 22.85 mol
then moles of O₂ = 22.85 ÷ 2 = 11.425 mol
Mass of O₂ = moles of O₂ × molar mass of O₂
= 11.425 mol × 32 g/mol
= 365.6 g
∴ <span>grams of oxygen are needed to react with 45.7 grams of hydrogen is 365.6g</span>
Answer:
water table is the level below which the ground is saturated with the water
<u>Answer:</u>
The temperature of the water is 70°C
<u>Explanation:</u>
Partial pressure of helium gas = 526 mmHg
Total pressure inside the jar= 760 mmHg
Suppose partial pressure of helium gas is 
and partial pressure of water is
And total pressure is 
As we know
Hence
Putting the values
In bar,
= 0.312 bar
Now according to the steam table
With the vapour pressure of water as 0.312 bar the temperature corresponds to 70°C
