Answer:
0.03g
Explanation:
Given parameters:
Number of moles of Na = 0.00125mole
Unknown:
Mass in grams of Na = ?
Solution:
To find the mass of this substance, we simply multiply the number of moles with the given molar mass of Na.
Mass of Na = number of moles x molar mass
Mass of Na = 0.00125 x 23 = 0.03g
Answer:
pressure of gas are constant describe the relationship between moles and temprature
A combustion reaction usually happens when a hydrocarbon is reacted with an oxygen molecule producing water and carbon dioxide. It is an exothermic reaction which means it releases heat as the process proceeds. It is a spontaneous process where it readily happens without any supply of energy. The total kinetic energy of the reactants is greater than the activation energy that is why heat is being released. Acetic acid is a carboxylic acid and is classified as a hydrocarbon so when reacted with oxygen, it would yield carbon dioxide and water. The balanced chemical reaction would be as follows
CH3COOH + 2 O2 = 2 CO2 +2 H2O
Electrons and newtrons is that what ur asking for
