1) If the volume of a container is increased, the temperature increases. 2) If the volume of a container is decreased, the temperature decreases. This means that the volume of a gas is directly proportional to its temperature. ... If the amount of gas in a container is increased, the volume increases.
Answer:
A decomposition reaction occurs when one reactant breaks down into two or more products. This can be represented by the general equation: AB → A + B. Examples of decomposition reactions include the breakdown of hydrogen peroxide to water and oxygen, and the breakdown of water to hydrogen and oxygen.
You can predict it by measuring the weight of the spherical object and measuring the liquid (mL) and subtracting finding the volume
elements like carbon ,nitrogen, sulfur and oxygen and etc are most likely to form covalent bonds
Standard reduction potential of Cd2+ = -0.403 v
Standard reduction potential of Cr3+ = -0.74 v
Here, reduction potential of Cd2+ is higher as compared to Cr3+. Hence, it will preferentially undergo reduction.
The electrochemical cell is represented as
Cr/Cr3+// Cd2+/Cd
Now, standard EMF of cell = E = ECd2+/Cd - ECr3+/Cr
= - 0.403. - (-0.74)
= 0.337 v
