Explain how thermal energy is transferred in convection.

Chemistry
1 answer:
Tpy6a [65]3 years ago
4 0

Answer:

Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated. ... As a result, the particles take up more volume.

Nickel (II) oxide reacts with carbon monoxide to form nickel metal. CO(g) + NiO(s) ⇄ CO2(g) + Ni(s) Kp = 20 at 873 K If a reacti
ozzi

Answer:

Explanation:

Hello,

Based on the statement of the equilibrium law:

Kp=\frac{P_{CO_2}^{EQ}}{P_{CO}^{EQ}}

By increasing (doubling) the amount of carbon monoxide, the production of nickel will increase since its amount is directly proportional with its pressure, so, by adding more reactant (in this case carbon monoxide), the equilibrium is rightward shifted based on Le Châtelier's principle even when solid either reactants or products are not contemplated in the equilibrium law.

Best regards.

How many grams of chlorine gas react when 266.28 grams of aluminum reacts
erma4kov [3.2K]

Answer:

524.82 g Cl2

Explanation:

Balanced Equation:

2Al(s) + 3Cl(g) ⇒ 2AlCl (s)

Al: 26.982 g/mol     Cl: 35.453 g/mol

266.28g Al x 1mol Al/ 26.982g Al x 3mol Cl2/ 2mol Al x

35.453g Cl2/ 1mol Cl2 = 524.82 g Cl2
