Explanation:
If pressure is increased, equilibrium shifts to the side with the fewer moles of gas.
There are 4 moles of gas in the reactants and 2 moles of gas in the products.
The equilibrium will shift in the forward direction towards the products.
Hope that helps.
Answer:
7.0 g/mL.
Explanation:
- Density is a characteristic property of a substance.
- The density of a substance is the relationship between the mass of the substance and the volume it takes up.
<em>d = m/V,</em>
where, d is the density of the metal,
m is the mass of the metal (m = 147 g),
V is the volume that the metal takes up (V = 41.0 mL - 20.0 mL = 21.0 mL).
<em>∴ d = m/V</em> = (147 g)/(21.0 mL) =<em> 7.0 g/mL.</em>
