Answer:
well gravity
Explanation:
gravity pull everything to earth
The exothermic process is a process or reaction that involves a release of energy from the system to its surroundings in various forms usually through heat, light, electricity or sound. In the four given choices, when melting a copper, you try to immerse the metal in heaping coals of fire. The metal will absorb the thermal energy coming from the coal, thus, once you retrieve the metal back, light will be emitted from it as well as heat.
Therefore, the answer is B. MELTING OF COPPER
A) probably some thin metal would work
B) Medium strength
C) either an electron or positron
D) 9.11x10^-31 kg
<h3><u>Answer;</u></h3>
pH = 6.12
<h3><u>Explanation</u>;</h3>
To calculate the pH of a solution, we use the equation;
pH = -log [H3O+]
Since we are given the hydronium ion (H
3
O
+
) concentration of the solution, we can plug this value into the formula.
pH = - log [ 7.6 × 10^–7 M]
= 6.12
Thus; pH = 6.12
