Answer:
Mass of KNO3= 10g
Molar mass of KNO3 = 101.1032g/mol
Volume = 250ml = 0.25L
No of mole on of KNO3 = mass of KNO3/Molar mass of KNO3
no of mole of KNO3 = 10/101.1032
No of mole of KNO3 = 0.09891
molarity of KNO3 = no of mole of KNO3/Vol (L)
Molarity = 0.09891/0.25 = 0.3956M
Molarity of KNO3 = 0.3956M
Here is your answer
Since, carbon atoms are triple bonded.
So functional group present in the compound is ALKYNE

1. <em>Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period. </em>
<em>2. Physical state of the reactants and surface area.</em>
Answer:
1. Both are made up of two substances that are chemically combined. 2. oxygen(O2) , 3. CARBON (C) , 4. AIR(N2 nixed with O2 AND CO2), 5. CANNOT BE SEPARATED BY PHYSICAL MEANS
