Answer:

The rate of the reaction would be halved.

Explanation:

The reaction is first order with respect to reactant A and second order with respect to reactant B. The rate equation is [A][B]^2

If the concentration of A is doubled and the concentration of B is halved, rate = 2 × (1/2)^2 = 2 × 1/4 = 1/2.

The rate would be halved.

Which of the following is NOT a true statement about liquids?
Nookie1986 [14]

Answer:

4

Explanation:

1 is correct

Liquids have no definite shape as they take up the shape of the container. Thus, we can say a liquid has no shape of its own but rather has the shape of the container in which it is filled.

2 is correct

When the atmospheric temperature is increased, it also will increase the boiling point of the liquid

3 is correct

This is an extension of the statement 2. While we decrease the atmospheric pressure, we are also decreasing the boiling point

4 is incorrect

A liquid have a definite volume. When we say a volume is definite, it means the volume is fixed and does not change. The volume of liquids is definite for a particular mass of the liquid and does not change

What are the difference between a red giant and a red super giant
bixtya [17]

So, unlike red giants, red supergiants are simply bright, red stars. It so happens that they may be in the same evolutionary state, but it is also possible that they have moved on. For example, most massive stars will appear as red supergiants while helium is fused into carbon in the core.



hope this helps you !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

(58 g)/ (4L) reduce units to one
katen-ka-za [31]

Answer is 14.5 g L⁻¹.

<em>Explanation;</em>

Here, the question says reduce the units as one.

The presented units are g/L. To reduce the units to one, what we can do is take L to the upper side.

This can be done according to the rules of indices;

1 / aˣ = a⁻ˣ

Like that, we can write 1 / L as L⁻¹.

Hence, the reduced unit is g L⁻¹.

But remember to keep a space between when writing two different units.

Actually, this is an unit for density.
