Answer: dilute
Explanation:
A concentrated solution which is used to prepare solutions of lower concentrations by diluting it with addition of water.
A dilute solution is one which contains lower concentration.
Using Molarity equation:
=concentration of stock solution = 0.150 mol/L
= volume of stock solution = 10.0 ml
= concentration of dilute solution = ?
= volume of dilute solution = (10.0+90.0) ml = 100.0 ml
As the concentration is less than the original concentration, the solution is termed as dilute.
Answer:
they causes climate change by trapping heat and also they contribute to respiratory diseases from smog and air pollution
Answer:C
Explanation: ice molecules are solid
<u>Answer:</u> The correct option is b) 600
<u>Explanation:</u>
Molecules are formed when two atoms of same or different elements combine together.
Atoms are the smallest unit of matter that combines to form a compound.
For the given chemical compound, 
Given number of molecules = 300 molecules
In 1 mole of the given chemical compound, there are 2 atoms of carbon, 4 atoms of hydrogen and 2 atoms of oxygen
Number of atoms of oxygen = 
Number of atoms of oxygen = 
Hence, the correct option is b) 600
