Answer : The mass of nitrogen needed are, 267.68 grams
Explanation :
Mass of = 325 g
Molar mass of = 17 g/mole
Molar mass of = 28 g/mole
First we have to calculate the moles of .
Now we have to calculate the moles of .
The balanced chemical reaction is,
From the balanced reaction we conclude that
As, 2 moles of obtained from 1 mole of
So, 19.12 moles of obtained from moles of
Now we have to calculate the mass of .
Therefore, the mass of nitrogen needed are, 267.68 grams
Answer:
It is Ka for the acid H3P2O72−.
Explanation:
Answer: The molar mass of the element is 40 g/mol and element is Calcium.
Explanation:
At STP:
1 mole of a gas contains 22.4 L of volume
Molar mass is defined as the mass of 1 mole of a substance.
To calculate mass of of the substance, we use the equation:
Volume of gas = 22.4 L
Density of gas = 1.7824 g/L
Putting values in above equation, we get:
The element having molar mass 40 g is Calcium.
Hence, the molar mass of the element is 40 g/mol and element is Calcium.

Exact answer (reword it yourself)
Explanation:
The Confederate States of America had a weaker central government than the United States, and individual states had more sovereignty and power that US states. The central government of the Confederate States handled only foreign issues or national economic issues.
A digital thermometer is more preferable than a liquid-based thermometer because it gives accurate data than the liquid thermometer. Liquid thermometer is affected by the temperature, and when it does, the liquid expands and so des the material covering the thermometer. For the digital thermometer, it has less error because it already has a sensor inside it that determines the temperature of the substance.
