An ionic bond occurs when an atom transfers or takes Electrons from another atom.
100.0g x 4.184J/g/°C x 78°C ΔT = 32,645.2 Joules.
The dependent variable is the variable that changes based on the independent variable (the manipulated variable).
Answer:
The correct option is this: DECREASING THE TEMPERATURE.
Explanation:
During the process of chemical reaction, the reacting molecules typically move about randomly in the reacting vessels colliding with one another and with the wall of the container. The rate of movement of the reacting particles can be reduced by decreasing the temperature of the reaction. If the temperature is reduced, the particles will lose kinetic energy and thus, they will move more slowly and collide less often with one another.
Answer:
The answer is
<h2>1.74 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of magnesium = 11.81 g
volume = 6.80 mL
The density of the metal is
We have the final answer as
<h3>1.74 g/mL</h3>
Hope this helps you
