If the equation CO(g) + 2H2(g) →← → ← CH3OH(g) + energy is for a system at equilibrium, increasing the temperature will cause __
Eddi Din [679]

Answer:

[CH₃OH] to decrease and [CO] to increase.

Explanation:

  • Since the energy appears as a product. So, the system is exothermic that releases heat.
  • Increasing the temperature of the system will cause the system to be shifted to the left side to attain the equilibrium again.
  • So, the right answer is:

<em>[CH₃OH] to decrease and [CO] to increase.</em>

When a substance is in the liquid state, how are the particles of that substance<br> behaving
iVinArrow [24]

Answer:

In liquids, particles are quite close together and move with random motion throughout the container. Particles move rapidly in all directions but collide with each other more frequently than in gases due to shorter distances between particles. With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion.

Choose the solvent below that would show the greatest freezing point lowering when used to make a 0.20 m nonelectrolyte solution
tatiyna

Answer : Carbon tetrachloride, k_f=29.9^oC/m will show the greatest freezing point lowering.

Explanation :

For non-electrolyte solution, the formula used for lowering in freezing point is,

\Delta T_f=k_f\times m

where,

\Delta T_f = lowering in freezing point

k_f = molal depression constant

m = molality

As per question, the molality is same for all the non-electrolyte solution. So, the lowering in freezing point is depend on the k_f only.

That means the higher the value of k_f, the higher will be the freezing point lowering.

From the given non-electrolyte solutions, the value of k_f of carbon tetrachloride is higher than the other solutions.

Therefore, Carbon tetrachloride, k_f=29.9^oC/m will show the greatest freezing point lowering.

The point of a cell division is to? a) copy tissue b) common cell c) neuron d) all choices are true
andrew-mc [135]

Answer: a) copy tissue

Explanation:

Tissue and cells in general get damaged, or just break down from wear and tear. So the cells divide to make up for this shortcoming, effectively replacing any broken parts with fresh new ones.
