To solve the question you use the following formula:
concentration (1) × volume (1) = concentration (1) × volume (1)
3 M × volume (1) = 1.8 M × 50 mL
volume (1) = (1.8 M × 50 mL) / 3 M = 30 mL
The balanced chemical equations are as follows:
- AlBr₃ + K → 3 KBr + Al
- FeO + PdF₂ → FeF₂ + PdO
- P₄ + 6 Br₂ → 4 PBr₃
- 2 LiCl + Br₂ → 2 LiBr + Cl₂
<h3>What are balanced chemical equations?</h3>
Balanced chemical equations in which the moles of atoms of elements taking part in a reaction are balanced on both sides of the equation.
The balancing of chemical equations follows the law of conservation of mass which states that matter can neither be created nor destroyed.
In balancing of chemical equations, the following steps are follows:
- ensure that the all the substances involved are written in the equation
- do not alter the formula of compounds or molecules
- add numerical coefficients in front of the compounds and molecules to ensure that the moles of atoms of elements are balanced on both sides of the equation
In conclusion, a balanced chemical equation obeys the law of conservation of mass.

The answer would be 3.37x10 to exponent 17.
Answer:
To determine how many electrons fit in each energy level, use the formula:
2n²
N is equal to the number of energy levels. Using this formula, we can determine that there are:
- First energy level holds 2 electrons
- Second energy level holds 8 electrons
- Third energy level holds 18 electrons
- Fourth energy level holds 32 electrons
- And so on...
Keep in mind though, that for an atom's outermost shell, it can only contain 8 valence electrons due to the octet rule that states that an element only needs eight electrons in their outermost shell in order to be stable.
