1. There is no graph given
2. ENERGY LEVELS!!!
Boiling is the process of liquid(middle energy, flat line) turning into a gas(lots of energy, flat line), hope this helps
Answer:
Mass of HCl = 73 g
Explanation:
Given data:
Mass of hydrogen = 2 g
Mass of HCl = ?
Solution:
First of all we will write the balance chemical equation:
H₂ + Cl₂ → 2HCl
Number of moles of hydrogen = 2 g/ 2g/mol
Number of moles of hydrogen = 1 mol
Form balanced chemical equation compare the moles hydrogen with HCl.
H₂ : HCl
1 : 2
Mass of HCl:
Mass of HCl = number of moles × molar mass
Mass of HCl = 2 mol × 36.5 g/mol
Mass of HCl = 73 g
Magnesium salt is the type of substance
The answer is: Survival of the form that will leave the most copies of itself in successive generations.
"Survival of the fittest" is a phrase that originated from Darwinian evolutionary theory.
This is example of natural selection and adaptation.
Genetic variation is important to the population's ability to survive in different situations that affect natural selection.
The environment is constantly changing and different alleles are favored.
A chemical equation should be balanced, so that when you make calculations based on the equation you must be able to relate the products to the reactants or vice versa. An example of using equations for calculations in chemistry is with the subject stoichiometry.
