Answer:
The mass left after 24.6 years is 25.0563 grams
Explanation:
The given parameters are;
The mass of the hydrogen-3 = 100 grams
The half life of hydrogen-3 which is also known as = 12.32 years
The formula for calculating half-life is given as follows;
Where;
N(t) = The mass left after t years
N₀ = The initial mass of the hydrogen-3 = 100 g
t = Time duration of the decay = 24.6 years
= Half-life = 12.32 years
The mass left after 24.6 years = 25.0563 grams.
Explanation:
First I'm going to draw the structure of the neutral calcium atom and the structure of the chlorine atom.
Now I'm going to draw only the valence shells of ions that participate in ionic bonding:
So Ca2+ will donate 2 electrons for both 2 atoms of Chlorine, forming CaCl2.
Most foods that are high in calcium are poor sources of iron. this statement illustrates the characteristic of a nutritious diet known as balance.
Nutrition is the biochemical and physiological processes by which organisms use food to sustain life. It provides organisms with nutrients that can be metabolized to produce energy and chemical structures. An inadequate supply of nutrients leads to malnutrition.
Although these two definitions may seem similar, there are differences. Health simply means food that protects you from disease and keeps you alive. Nutrient-rich foods mean foods that provide sufficient nutrients (vitamins, carbohydrates, proteins) that the body needs to survive the kind that is either low in fiber or high in fat, salt, and/or sugar. Eating too much food or drink.
