What happens to the rate of the reaction as temperature increases

Chemistry

Answer: d. The rate increases because molecules are moving faster.

Explanation:

Rate of reaction is determined by the number of effective collisions which means how many collisions are resulting into products. The molecules must possess a certain minimum energy in order to get converted to products.

Increasing the temperature means more reactant molecules will have sufficient energies to cross the energy barrier and thus the number of effective collisions increases, thus leading to more products and increased rate of reaction.

A machine has a mechanical advantage of 0.6. What force should be applied to the machine to make it apply 600 N to an object?

Vinil7 [7]

Answer:

1000N is needed to be applied.

Explanation:

Machines make doing work easier. They allow us use small effort to carry out work on huge amount of load.

The mechanical advantage of a machine;

(M.A) =load/effort

M.A = 0.6

Load =600N

effort =?

0.6 = 600/effort

effort = 600/0.6

effort = 1000N

Match the name of each gas law to the properties it compares. 1. Gay-Lussac's law 2. Boyle's law 3. Avogadro's law a. Volume and

oee [108]

Answer:

1. C 2. B 3. A

Explanation:

1. Gay- Lussac law, states that as along as the volume is kept constant, the pressure of a fixed mass of gas is directly proportional to the temperature.

The properties it compares is; (c.) Pressure and temperature

2. Boyle's Law states that; as long as the temperature is kept constant, the volume of a fixed mass of gas is inversely proportional to the pressure.

It therefore compares; (b.) Pressure and volume

3. Avogadro's Law states that equal volumes of different gases contain the same number of molecules provided the temperature and pressure are the same.

It therefore compares; (a.) Volume and moles

A balloon has a volume of 3.50 liters at 20.0°C. What will be the volume of the balloon at 100.0°C? Assume the pressure doesn't

Nikitich [7]

Answer: The volume of balloon at 100°C is 4.46 L

Explanation:

To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{V_1}{T_1}=\frac{V_2}{T_2}$
