How many grams of glucose are produced from 10.3 g of co2

There are produced 6.72 g

Explanation:

This is the reaction:

C₆H₁₂O₆  +  6O₂  →  6CO₂  +  6H₂O

1 mol of glucose reacts with 6 moles of oxygen, to make 6 moles of dioxide and 6 moles of water

Molar mass of CO₂ = 46 g/m

Moles CO₂ = 10.3 g/ 46g/m = 0.224 moles

Ratio is 6:1

6 moles of CO₂ are made from 1  mol of glucose

0.224 moles of CO₂ are made from (0.224 . 1)/6 = 0.0373 moles of glucose

Molar mass glucose = 180.15 g/m

Mass glucose = moles . molar mass

0.0373 m . 180.15 g/m = 6.72 g

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

the answer is na (sodium)
