The atomic mass on the periodic table represents the sum of number of protons and number of neutrons.
Atomic mass = Number of protons + number of neutrons
Hope this helps!
Answer:
Number of moles = 3.73 mol
Explanation:
Given data:
Mass of LiCl = 158 g
Number of moles = ?
Solution:
Formula:
Number of moles = mass/ molar mass
Molar mass of LiCl = 42.4 g/mol
Number of moles = 158 g / 42.4 g/mol
Number of moles = 3.73 mol
Water and carbon dioxide respectively
Photosyntheis is a biochemical reaction that combines chemicals with biological species to produce energy. Atoms of hydrogen bond with carbon to form glucose.
<h3>What are the reactants and the products of the light reaction?</h3>
Carbon dioxide and hydrogen are the reactants that are used from the environment by the plants to make energy. Glucose and oxygen are the products.
The hydrogen atoms from the environment are absorbed by the plants and are combined with the carbon dioxide to yield glucose or sugar molecules for energy.
Therefore, option B. hydrogen and carbon dioxide react to produce glucose.

Answer:
The molar heat capacity at constant volume is 21.62 JK⁻¹mol⁻¹
The molar heat capacity at constant pressure is 29.93 JK⁻¹mol⁻¹
Explanation:
We can calculate the molar heat capacity at constant pressure from
Where 
is the molar heat capacity at constant pressure
is the heat capacity at constant pressure
and 
is the number of moles
Also is given by
Hence,
becomes
From the question,
= 229.0 J
= 3.00 mol
= 2.55 K
Hence,
becomes
29.93 JK⁻¹mol⁻¹
This is the molar heat capacity at constant pressure
For, the molar heat capacity at constant volume,
From the formula
Where 
is the molar heat capacity at constant volume
and 
is the gas constant ( = 8.314 JK⁻¹mol⁻¹)
Then,
21.62 JK⁻¹mol⁻¹
This is the molar heat capacity at constant volume
