Answer:
7 protons
Isotopes are atoms that have the same number of protons but different numbers of neutrons in the nucleus. You know that nitrogen-14 has 7 protons in the nucleus because it is an isotope of nitrogen, which has an atomic number equal to 7 .
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.

Answer:
G - H2SO4
Explanation:
two hydrogen atoms and 4 oxygen atoms
Answer:
1 is the correct answer of the question
Answer:
coefficient 3 is needed t with water molecule to balance the equation.
Explanation:
Chemical equation:
Fe₂O₃ + H₂SO₄ → Fe₂(SO₄)₃ + H₂O
Balanced chemical equation:
Fe₂O₃ + 3H₂SO₄ → Fe₂(SO₄)₃ + 3H₂O
The equation is balanced. There are two iron three sulfate six hydrogen and three oxygen atoms are present on both side of equation.
The given equation completely follow the law of conservation of mass.
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Coefficient with reactant and product:
Fe₂O₃ 1
H₂SO₄ 3
Fe₂(SO₄)₃ 1
H₂O 3
So coefficient 3 is needed t with water molecule to balance the equation.
