Answer:

Correct option is D.

It accelerates the reaction rates of a mixture.

Explanation:

It is used to speed up a reaction by lowering the activation energy.Catalysis is the backbone of many industrial processes, which use chemical reactions to turn raw materials into useful products.

Types

There are two types of catalyst (1) Homogeneous (2) Heterogeneous

In a heterogeneous reaction, the catalyst is in a different phase from the reactants. In a homogeneous reaction, the catalyst is in the same phase as the reactants.

What is the frequency of radiation whose wavelength is 2.25 X 10^-5cm?

Semenov [28]

Answer:

1.25 x 10^15Hz

Explanation:

c = frequency x wavelength

c is the speed of light, which is equal to 3.00 x 10^8 m / s

frequency = c /wavelength

= (3.00 x 10^8m /s) / (2.40 x 10^-5 cm x 1 m /100cm)

= (3.00 x 10^8 m/s) / 2.40 x 10^-7m

= 1.25 x 10^15/s 1 / s = 1Hz

So, the Frequency = 1.25 x 10^15Hz

I hope this helped :)

What effect does rapid exhalation of CO2 during exercise have on the concentration of H2CO3 in the blood?

BARSIC [14]

If there is a constant loss of $CO_{2}~(carbon~dioxide)$ the concentration of $H_{2} CO_{3}~(carbonic~acid)$ will be affected and decrease since $CO_{2}$ is a main component of $H_{2}CO_{3}$ .
