saveliy_v [14]
It's 3. There are two Cl in the reactants and 3 in the products, and they need to be balanced/equal. Only way to do that is add three on the left side, which will give you 6 Cl (3×2Cl) and then 2 on the other side, which will also give you 6 Cl (2×3Cl)

How does the vapor pressure of water at 10°C compared with its vapor pressure at 50°C ?​
Sliva [168]

Answer: The vapor pressure of water at 10°C will be less as compared with its vapor pressure at 50°C.

Explanation:

Vapor pressure of a liquid  is defined as the pressure exerted by the vapors  in equilibrium with the liquid/solution at a particular temperature.

As Kinetic energy is dependent on the absolute temperature of the gas.

K.E=\frac{3}{2}RT

where R = gas constant

T = temperature

On increase in temperature, the kinetic energy of the molecules increase and thus more liquid molecules can escape to form vapours and thus will exert more vapor pressure.

Thus the vapor pressure of water at 10°C will be less as compared with its vapor pressure at 50°C.

onsider the following cyclic process carried out in two steps on a gas: Step 1: 42 J of heat is added to the gas, and 14 J of ex
Tema [17]

Answer:

W = -25 J

Explanation:

For a cyclic process, the variation of internal energy (ΔU) must be 0. It means that ΔU from step 1 must be equal to ΔU from step 2. For the first law of the thermodynamics, the energy must be conserved, so:

ΔU = Q - W, from each step. Q is the heat and W the work

When the heat is gained by the system, the process is endothermic, so Q >0, when the system loses heat, the process is exothermic, and Q<0. When the system is expanding W>0, and when it is compressing, W<0.

From step 1:

ΔU = 42 - 14

ΔU = 28 J

From step 2:

28 = -53 - W

W = -53 + 28

W = -25 J
