Explain how changes in pressure affect the rate and yield of ammonia produced

vesna_86 [32]

Answer:

If the pressure is increased, the equilibrium position moves to the right, so the yield of ammonia increases. The rate of reaction also increases because the gas molecules are closer together, so successful collisions are more frequent.

The mass of a block is 12 g and the volume is 6 ml. Calculate the density of the block.

HACTEHA [7]

Answer:

According to mass and volume, block density is 2 g/ml

Explanation:

Density is a measure, usually used in physics and chemistry, that relates the mass and volume of a solid or compound.

In general terms, the density is directly proportional to the mass, and inversely proportional to the volume, so increasing the mass will also increase the density.

The formula used to calculate the density is

ρ = $\frac{m}{V}$
