Answer: The correct option is, They are different units of concentration.
Explanation: Molarity : It is defined as the number of moles of solute present in one liter of solution.
Answer:
We actually output other gases like methane lol
Explanation:
Well since most of the air we breathe is made up of nitrogen we also breathe out nitrogen

Answer:
Percent Yield = 80%
Explanation:
Percent yield of a reaction is defined as one hundred times the ratio between the actual yield and the theoretical yield. That is:
Percent yield = Actual Yield / Theoretical Yield * 100
<em>Where theoretical yield of CaHPO4 is 10g and actual yield is 8g</em>
Replacing:
Percent yield = 8g / 10g * 100
<h3>Percent Yield = 80%</h3>
Hcl + nh3 -> nh4cl (balanced eqn)
no. of mol of hcl = vol. (L) x molarity = 0.045 × 0.25 = 0.01125mol
ratio of hcl:nh3 after balancing eqn = 1:1
no. of mol of nh3 that is completely neutralised by hcl = 0.01125 × 1 = 0.01125mol
therefore, concentration of nh3 = mol / total volume (L) = 0.01125mol / 0.025L= 0.45M
In a composition reaction, two or more reactants -- often but not always elements -- combine to form a more complex compound.
