How many atoms are in NaHCO3? And please explain how u got the answer.

There are 6 atoms in NaHCO3

Explanation:

NaHCO3 is a bicarbonate commonly known as baking soda.

It has one sodium atom, one hydrogen atom, one carbon atom, and three oxygen atoms

The number of atoms = 1 atom of Na + 1 atom of H + 1 atom of C + 3 atoms of O

= 6 atoms per molecule

Note: know the formula of the compound first, each element present in the compound and how many times they occur makes the total number of atoms making up the compound or present in the compound.

Number of atoms are the number of element present

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
