Answer:
Oxygen and Magnesium together, OMg?!?!
The most stable electron configuration helium has.
He
Answer:
Decreasing the concentration of N2O3
Explanation:
This is because the products on the right of the reaction occupy more space. One (1) mole of NO and another mole of NO2 will occupy more space than the one (1) mole of N2O3. Therefore decreasing the concentration of N2O3 will shift the reaction to the right because the products will have more space to occupy – hence favoring equilibrium.

Answer:</h3>
8.64 g
<h3>
Explanation:</h3>
- Density is the ratio of mass of substance to its volume.
- It is calculated by dividing the mass of a substance by its volume.
- Density = Mass ÷ Volume
In this case we are given,
Volume of sodium chloride = 4.00 cm³
Density of sodium chloride = 2.16 g/cm³
We are required to calculate the mass of sodium chloride,
Rearranging the formula;
Mass = Density × volume
Mass of sodium chloride = 2.16 g/cm³ × 4.00 cm³
= 8.64 g
Therefore, the mass of sodium chloride is 8.64 g
