A physical change is a change in which the physical properties of matter are altered. These are properties are the forms and state.

Most physical changes are easily reversible and are pure state changes.

They do not lead to the production of new compounds.

They involve no mass change and requires little to no energy.

Examples are melting, boiling, freezing, sublimation e.t.c

The ph of a 0.55 m aqueous solution of hypobromous acid, hbro, at 25.0 Â°c is 4.48. what is the value of ka for hbro?

gladu [14]

Hbro dissociate as follows
HBro---> H+ + BrO-
Ka= (H+)(BrO-) / HBro
PH = -log (H+)
therefore (H+) = 10^-4.48= 3.31 x10^-5
ka is therefore= ( 3.31 x 10^-5)^2/0.55=1.99 x10^-9

If a substance has a mass of 12.50 g and takes up 3.4 mL of space, what is the density?

miskamm [114]

Answer:

The answer is

Explanation:

The density of a substance can be found by using the formula

<h3> $density = \frac{mass}{volume}$ </h3>

From the question

mass of substance = 12.50 g

volume = 3.4 mL

The density of the substance is

$density = \frac{12.50}{3.4} \\ = 3.676470588...$

We have the final answer as

Hope this helps you
