Answer: ammonium bromide : acidic : The pH will be less than 7.
potassium cyanide : basic :The pH will be more than 7.
calcium nitrate: neutral : The pH will be approximately equal to 7.
calcium hypochlorite : basic :The pH will be more than 7.
Explanation:
pH is defined as the negative logarithm of hydrogen ion concentration. The scale ranges from 0 to 14.
When a solution is acidic, it will show a pH in the range of 0 - 6.9. When a solution is basic, it will show a pH in the range of 7.1 - 14. When a solution is neutral, it will show a pH of 7.
ammonium bromide : 
: acidic as it is formed from the combination of strong acid HBr and weak base 
potassium cyanide :
: basic, as it is formed from the combination of weak acid HCN and strong base KOH
calcium nitrate: 
: neutral, as it is formed from the combination of strong acid and strong base.
calcium hypochlorite : 
: basic, as it is formed from the combination of weak acid 
and strong base

Answer:
2KClO3 —> 2KCl + 3O2
The coefficients are 2, 2, 3
Explanation:
From the question given above, we obtained the following equation:
KClO3 —> 2KCl + 3O2
The above equation can be balance as follow:
There are 2 atoms of K on the right side and 1 atom on the left side. It can be balance by putting 2 in front of KClO3 as shown below:
2KClO3 —> 2KCl + 3O2
Now, the equation is balanced.
Thus, the coefficients are 2, 2, 3
Answer: check explanation
Explanation:
In this question we are to find mass. In order to calculate the Mass, We need the values of two parameters, that is, the values given for the grade tow chain, and the value given for the mass per length.
Assuming the mass per length is 3 Kilogram per metre(kg/m) and the grade 70 tow chain length is 5 metre(m).
Therefore, the formula for calculating mass of the chain is given below;
Mass of the chain= mass per unit length(kg/m) × length ---------------------------------------------------------------------------------------------------------------------(1).
Mass of the chain= 3 kg/m × 5 m.
Mass of the chain= 15 kg.
Answer: 3.338832 kilojoules
