gas?

Following the ideal gas law PV = nRT, and changing it in terms of pressure we get P = nRT/V. When the absolute temperature of a gas is increased four times while maintaining constant volume, the pressure of the gas also increases four times. The pressure increases because temperature is directly proportional with pressure.

Carbon monoxide and chlorine combine in an equilibrium reaction to produce the highly toxic product, phosgene (COCl2 ) CO(g) Cl2
Anuta_ua [19.1K]

Answer:

Reaction will proceed towards forward direction.

Explanation:

Balanced reaction: CO+Cl_{2}\rightleftharpoons COCl_{2}

Reaction quotient (Q_{c}) for this reaction is represented as:

                                         Q_{c}=\frac{[COCl_{2}]}{[CO][Cl_{2}]}

Here, [CO] = [Cl_{2}] = 0.010 M and [COCl_{2}] = 0.070 M

                              So, Q_{c}=\frac{0.070}{(0.010)^{2}} = 700

As Q_{c} > K_{c} therefore reaction will proceed towards forward direction i.e. moreCOCl_{2} will be produced.

PLEASE HELP!

Answer:

Q = 2.60 • 10^{3} J

Explanation:

Our specific heat capacity equation is:

Q = mC∆T

Q is the energy in joules.

m is the mass of the substance.

∆T is the temperature chance.

Let's plug in what we know.

  • We have 76.0 g of octane
  • The specific heat capacity of octane is 2.22 J/(g•K)
  • The temperature increases from 10.6º to 26.0º (a 15.4º increase)

Q = 76.0(2.22)(15.4)

Multiply.

Q = 2598.288

We want three significant figures.

Q = 2.60 • 10^{3}

or

Q = 2590 J

Hope this helps!

Answer:

A & E

Explanation:

Salt water is a hypertonic solution, meaning it extracts water from whatever is placed in it. When a carrot loses water, it will most likely shrivel up and become limp.
