PH scale is used to determine how acidic or basic a solution is.
we have been given the hydrogen ion concentration. Using this we can calculate pH,
pH = - log[H⁺]
pH = - log (1 x 10⁻¹ M)
pH = 1
using pH can calculate pOH
pH + pOH = 14
pOH = 14 - 1
pOH = 13
using pOH we can calculate the hydroxide ion concentration 
pOH = - log [OH⁻] 
[OH⁻] = antilog(-pOH)
[OH⁻] = 10⁻¹³ M
hydroxide ion concentration is 10⁻¹³ M

A completely reversible heat pump has a COP of 1.6 and a sink temperature of 300 K. Calculate (a) the temperature of the source
sesenic [268]

Answer:

(A) 800 K (B) 2.4 KW

Explanation:

We have given the COP =1.6

The sink temperature T_L=300K

We have to find the source temperature, that is T_H

(A) We know that COP of the heat pump is given by COP=\frac{T_H}{T_H-T_L}

So 1.6=\frac{T_H}{T_H-300}

1.6T_H-480=T_H

0.6T_H=480

T_H=800K

(B) We have given the work done =1.5 KW

The rate of heat transfer is given by Q_H=COP\times W=1.6\times 1.5=2.4KW

scoray [572]

Answer:

The answer to your question is    HCl  +  NaOH   ⇒   NaCl  +  H₂O

Explanation:

Data

Double displacement reaction

Balanced chemical reaction

               HCl  +  NaOH   ⇒   NaCl  +  H₂O

           Reactants           Elements                Products

                 1                  Chlorine (Cl)                    1

                 1                   Sodium (Na)                   1

                 2                 Hydrogen (H)                  2

                 1                   Oxygen (0)                      1

As we can see, the reaction is balanced and the coefficients of all reactants and products are 1, but the number is not written in a balanced reaction.

Identify two ways that the rate of a chemical reaction could be increased
Svetlanka [38]
Increase the Surface Area of the Reactants. Increasing the surface area of the reactants increases the rate of the reaction. More surface area means more collisions of the reactant molecules and an increased rate of the reaction. This occurs when reactants are made to react in powdered form
