<h3>Answer </h3>

Ca(OH)2 (s) + 2HCl (aq) = CaCl2 (aq)+ 2H2O (l)

<h3>Explanation </h3>

Calcium hydroxide is a fairly strong base, and hydrochloric acid is a strong acid. The two substances readily react with and neutralise each other, forming the soluble salt calcium chloride (CaCl2) and water. This reaction is called neutralization.

In this reaction one mole of calcium hydroxide react with 2 mole of hydrochloric acid to produce one mole of calcium chloride and 2 mole of water.

The calcium hydroxide and hydrochloric acid break down to form ions.

• Ca(OH)2  ----------------> Ca2+  +  2OH-

• HCL. -------------> H+  +  Cl+

So there occurs the ion exchange method and the overall chemical equation is as follows.

• Ca(OH)2  +  2HCL. ----------->  CaCl2  +  2 H2O

If I have 6 moles of a gas at a pressure of 3.4 atm and a volume of 10 liters, what
ch4aika [34]

Answer:

The temperature is 69.05 K.  

Explanation:

We have,

Number of moles are 6

Pressure is 3.4 atm and a volume of 10 liters.

It is required to find the temperature. It can be calculated using gas law equation. It says that,

PV=nRT

P is pressure

V is volume

n is number of moles

R is gas constant, R=0.082057\ L-atm/mol-K

T is temperature                

Plugging all the values we get :

T=\dfrac{PV}{nR}\\\\T=\dfrac{3.4\times 10}{6\times 0.082057}\\\\T=69.05\ K

So, the temperature is 69.05 K.

The volume of a gas is 4.0 L when the pressure is 1.00 atm. At the same temperature, what is the pressure at which the volume of
Leokris [45]

<u>Answer:</u> 2.00 atm

<u>Explanation:</u>

The gas is kept under the same temperature in this problem. Assuming the amount of gas is constant, we can apply the Boyle's law.

The Boyle's law equation,

P₁V₁ =  P₂V  ₂

Plug in the values,

1.00 atm x 4.0 L =  P₂  x 2.0 L

Simplify,

4.00 atm L = 2  P₂ L

Now flip the equation,

2  P₂ L = 4.00 atm L

Dividing both sides by 2 we get,

P₂ = 2.00 atm

How many grams of NH3 can be produced from the reaction of 28g of N2 and 25g of H2?
Reika [66]
N2<span> + 3H</span>2<span> = 2NH</span><span>3
so, NH3 = (N2 + 3H2)/ 2
            =  (28g + 3*25g)/2
            = 51.5g</span>
