Answer:

solubility=0.25mol/dm^3

Explanation:

number of moles of solute=0.03mol

volume of solution in dm³=1.2dm³

solubility=?

as we know that

solubility=\frac{number of moles of solute}{volume of solution indm}

solubility=\frac{0.03mol}{1.2dm^3}

solubility=0.25mol/dm^3

i hope this will help you :)

Answer:

The Earth's surface is constantly changing through forces in nature. The daily processes of precipitation, wind and land movement result in changes to landforms over a long period of time. Driving forces include erosion, volcanoes and earthquakes. People also contribute to changes in the appearance of land.

Answer:

1)Krypton

2)11H

Explanation:

electrons=protons

protons=atomic number

mass number=protons+neutrons

mass number is the superscript

atomic number is the subscript.

1)The answer is Krypton because its atomic number= number of protons=number of electrons is 36.

mass number is 46+36=82.

2)subscript=atomic number=number of protons=number of electrons

i. H = electrons=1

=neutrons=0

ii. Cl=electrons=17

=neutrons=35-17=18

iii. Na=electrons=11

=neutrons=23-11= 12

so the answer is Hydrogen because it has 1 electron and 0 neutron.

I hope this helps.
