By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.
Answer:
1864.11 m³
Explanation:
Let's suppose the gas is acting ideally, then according to <em>Charles's Law</em>, "T<em>he volume of a fixed mass of gas at constant pressure is directly proportional to the absolute temperature</em>". Mathematically for initial and final states the relation is as follow,
V₁ / T₁ = V₂ / T₂
Data Given;
V₁ = <u>??</u>
T₁ = 20 °C = 293.15 K
V₂ = 2500 m³
T₂ = 120 °C = 393.15 K
Solving equation for V₁,
V₁ = V₂ T₁ / T₂
Putting values,
V₁ = (2500 m³ × 293.15 K) ÷ 393.15 K
V₁ = 1864.11 m³
Result:
When 1864.11 m³ volume of gas at 20 °C is allowed to enter a balloon at 120 °C, then the volume will increase to 2500 m³.
Explanation:
A chemical equation represents a simple chemical reaction. Chemical reactions occur when atoms are rearranged in a compound to produce new ones.
There are different types of chemical reactions but all chemical equations are expressed in a simple way.
Chemical equations are made up of reactants and products.
The reactants are the species on the left hand side of the chemical equation. They are the species combining or breaking down to give the product.
The products are the results obtained from the combination of the reactants. For example in the equation below;
A + B → C + D
A and B are the reactants
C and D are the products.

Answer:
C
Explanation:
Ome of the products may not always be H2O
Ca, they only have two valence electrons, in order to become more stable, they would like to lose all of them
