How much time will it take a car travelling at 88 km/hr (55mi/hr)to travel 500km?
dybincka [34]
The time it will take for a car travelling 88 km/hr (55mi/hr) to travel 500km would be 3.5 hours.

How? Add 88 + 58.

That'll equal 143, then divide 500 ÷ 143 = 3.5

So, 3.5 is the time that the car will take travelling 88 km/hr trying to reach the destination of 500km.

The equilibrium constant for A + 2B → 3C is 2.1 * 10^-6
Mariana [72]

Answer:

b- 4.4 * 10^-12.

Explanation:

Hello.

In this case, as the reaction:

A + 2B → 3C

Has an equilibrium expression of:

K_1=\frac{[C]^3}{[A][B]^2}=2.1x10^{-6}

If we analyze the reaction:

2A + 4B → 6C

Which is twice the initial one, the equilibrium expression is:

K_2=\frac{[C]^6}{[A]^2[B]^4}

It means that the equilibrium constant of the second reaction is equal to the equilibrium constant of the first reaction powered to second power:

K_2=K_1^2

Thus, the equilibrium constant of the second reaction turns out:

K_2=(2.1 * 10^{-6})^2\\\\K_2=4.4x10^{-12}

Therefore, the answer is b- 4.4 * 10^-12.

Best regards.

How many grams of fluorine must be reacted with excess lithium iodide to produce 10.0 grams of lithium fluoride?
rewona [7]
Answer:
             7.32 g of F₂

Solution:
              The equation is as follow,

                                   2 LiI  +  F₂    →    2 LiF  +  I₂

According to equation,

           51.88 g (2 mole) of LiF is produced from  =  37.99 g (1 mole) F₂
So,
                          10 g of LiF will be produced by  =  X g of F₂

Solving for X,
                      X  =  (10 g × 37.99 g) ÷ 51.88 g

                      X  =  7.32 g of F₂
