Answer:
V = 22.41 L
Explanation:
Given data:
Mass of nitrogen = 14.0 g
Volume of gas at STP = ?
Gas constant = 0.0821 atm.L/mol.K
Solution:
Number of moles of gas:
Number of moles = mass/molar mass
Number of moles= 14 g/ 14 g/mol
Number of moles = 1 mol
Volume of gas:
PV = nRT
1 atm × V = 1 mol × 0.0821 atm.L/mol.K × 273 K
V = 22.41 atm.L / 1 atm
V = 22.41 L
Answer:
Beryllium (Be) : 9.01 g/mol
Silicon (Si) : 28.09 g/mol
Calcium (Ca) : 40.08 g/mol
Rhodium (Rh) : 102.91 g/mol
Explanation:
Stationary Front: a front that is not moving. When a warm or cold front stops moving, it becomes a stationary front.

Answer:
Explanation:
The intermediates are the products of all the steps of the reaction pathway, with the exception of the last one. So the intermediates will be:
- N2O2 from the first step
- N2O from the second step
The list from reactant to final product:
<em>Note: the water is considered a by-product, given that is not the product of interest in this steps.</em>
