Answer:
The conventional oven and the convection oven are confused with each other due to their similar look and style, and a lot of their functioning is quite the same as well.
The conventional ovens have existed for over half a century, and have derived their functioning from traditional ovens that are over 4,000 years. They function with a bottom-up heat transfer from a fixed burner source.
The convection ovens were made recently as a way to get better heating results for all types of dishes and recipes, with the introduction of a fan system along with an exhaust which allows the circulation of hot air around the cavity of the oven.

Hello.
In this case, given the described reaction, the formation of nitric acid turns out:
Since two hydrogen atoms are present at the reactants we balance it as follows:
In such a way, since there is a 1:2 mole ratio between water and nitric acid, the produced moles of nitric acid, turns out:
Best regards!
First you need to find the amount of mass of Na2CO3 in one moles
(Use periodic chart)
Na= 22.99 x 2 = 45.98
C = 12.01
O = 16.00 x 4 = 64.00
Add the molar masses together to get 121.99
To find how many grams are in 4 moles, times 121.99 by 4
This gives you 487.96
But the questions asks for the answer to be in kilograms nor grams, to change into kilograms divide by 1000
This gets you the answer: 0.49 kg
