Answer: 2N2O3 -> 2N2 + 3O2
Explanation:
Deuterium, Deuterium is an isotope of hydrogen that is composed of one proton, one neutron, and one electron. The nucleus of deuterium is composed of a proton and a neutron. The symbol for deuterium is given as 2H. The atomic number of deuterium is 1 and the mass number is 2.
Answer:
50 g of K₂CO₃ are needed
Explanation:
How many grams of K₂CO₃ are needed to make 500 g of a 10% m/m solution?
We analyse data:
500 g is the mass of the solution we want
10% m/m is a sort of concentration, in this case means that 10 g of solute (K₂CO₃) are contained in 100 g of solution
Therefore we can solve this, by a rule of three:
In 100 g of solution we have 10 g of K₂CO₃
In 500 g of solution we may have, (500 . 10) / 100 = 50 g of K₂CO₃
