A solution that is 4 on pH scale is an acid. A pH scale is used to measure whether a solution is an acid or a base. the pH scale is numbered between 0 to 14. 7 is the neutral point of this scale. Any solution having a pH of 7 is a neutral solution. Acidity of a solution increases as the reading in the scale decreases from seven towards zero. The basic nature of the solution increases as the pH level of the solution increases from 7 towards 14. The acidic nature of a solution having pH value of 3 is ten times more acidic than a solution having pH value of 4. The same thing is same while comparing basic solutions as well.

A pH scale runs from 1 to 14 with 7 being neutral.

1-6 has base like properties
8-14 has avid line properties

since this solution has a pH scale of 4.... the solution is basic

In balancing the nuclear reaction 7535Br → E + 01e, the identity of element E is ________. In balancing the nuclear reaction Br

nordsb [41]

Answer: The element E is Krypton (Kr).

Explanation:

In a nuclear reaction, the total mass and total atomic number remains the same.

The given nuclear reaction follows:

$_{35}^{75}\textrm{Br}\rightarrow ^{A}_{Z}\textrm{X}+^0_{-1}\textrm{e}$

To calculate A:

Total mass on reactant side = total mass on product side

75 = A + 0

A = 75

To calculate Z:

Total atomic number on reactant side = total atomic number on product side

35 = Z + (-1)

Z = 36

The isotopic symbol of element E is $_{36}^{75}\textrm{Kr}$

Hence, the element E is Krypton (Kr).

What is the source of energy that is released in an exothermic reaction? what absorbs the energy that is released ?

Nadusha1986 [10]

Hello,

Here are your answers:

The proper answers to your questions are....

1. "Chemical bond energy is converted to kinetic energy"...... which causes it to release energy around its surroundings!

2. "Endothermic reactions"...... Endothermic reactions are the things that absorb the energy!

If you need anymore help feel free to ask me!

Hope this helps!
