When 30 grams of wood burns completely in 50 grams of oxygen, 35 grams of water vapor and some carbon dioxide are given off.
identify each of the reactant(s) and product(s) in this reaction. (2 points)
how many grams of carbon dioxide would be produced in this example?
what is the name of the law that you used to determine the answer for b?

There would be produced 45g of CO2, based on the Law of conservation of mass.

Explanation:

1)

Woods + Oxygen  → Carbon dioxide + water vapor  

Reactant(s): These are the substance(s) or material which will undergo a chemical change to form new products.

⇒Here the reactants are Wood + oxygen

⇒This meas wood will be burning in the presence of oxygen ( O2)

Products : These are substances which are formed in a chemical reaction when new bonds are formed.  

⇒Here the products are Carbon dioxide + water vapor

2) Mass of reactants = 30g of woods + 50g = 80g

Mass of products = mass of CO2 + 35g of water vapor

Since ' Law of conservation of mass' says: . Mass is neither destroyed nor created in an chemical reaction . Or Mass of  elements before reaction is equal to mass of elements after the reaction .

This means that mass reactants = mass of products

Here is 80g = mass of CO2 + 35g of water vapor

this means that mass of CO2 = 80g - 35g = 45g

There would be produced 45g of CO2, based on the Law of conservation of mass.

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
