Matter that has a uniform and definite composition is called a vapor
Answer:
1.75 moles of H₂O
Solution:
The Balance Chemical Equation is as follow,
N₂H₄ + O₂ → N₂ + 2 H₂O
Step 1: Calculate the Limiting Reagent,
According to Balance equation,
32.04 g (1 mol) N₂H₄ reacts with = 32 g (1 mol) of O₂
So,
28 g of N₂H₄ will react with = X g of O₂
Solving for X,
X = (28 g × 32 g) ÷ 32.04 g
X = 27.96 g of O₂
It means 29 g of N₂H₄ requires 47.96 g of O₂, while we are provided with 73 g of O₂ which is in excess. Therefore, N₂H₄ is the limiting reagent and will control the yield of products.
Step 2: Calculate moles of Water produced,
According to equation,
32.04 g (1 mol) of N₂H₄ produces = 2 moles of H₂O
So,
28 g of N₂H₄ will produce = X moles of H₂O
Solving for X,
X = (28 g × 2 mol) ÷ 32.04 g
X = 1.75 moles of H₂O
Answer:

Answer: option (A)
Explanation: The convection current is generates in the mantle due to the heat radiated from the core of the earth. Due to this convection current, the lithospheric plates moves as the upper part of the mantle known as the asthenosphere, is the region which is viscous in nature and drives the plates to move. This is a repeating cycle that constantly forces the plates to move.
Thus the correct answer is option (A).
The number of turns that citric acid cycle will turn when 57.3 g of glucose (C6H1206) is oxidized in the cells is 1.92 × 10²³ turns.
<h3>How to calculate number of turns?</h3>
According to this question, Acetyl CoA turns the citric acid cycle one turn.
First, we find the number of moles of 57.3 grams of glucose by dividing by its molar mass of 180g/mol.
no of moles = 57.3/180 = 0.32moles
Next, we multiply the number of moles by Avogadro's number i.e. 6.02 × 10²³ molecules.
no of turns = 6.02 × 10²³ × 0.32
no of turns = 1.92 × 10²³ turns
Therefore, the number of turns that citric acid cycle will turn when 57.3 g of glucose (C6H1206) is oxidized in the cells is 1.92 × 10²³ turns.
