3 0
1) A. the have different protons.

The number of protons is the atomic number and this is how the products are ordered in the periodic table. Every element has different atomic number.

2) A. 8 p, 8 e and 8 n

The atomic number of O is 8, which means it has 8 protons. The number of protons must equal the number of electrons.

3) C. atoms bond with one another in a molecule.

That is what a molecule is: a group ot atoms bonded.

4) D. the bond results from the attractive forces of two opposite charges.

Ionic bonds are formed between ions, a positive ion (cation) and a negative ion (anion).

5) A. the physical and chemical properties of HCl are different from those of H2 and Cl2

You can check physical properties (density for example) and chemical properties (how they react with other elements) in some tables o textbooks.

For the oxidation of glucose C6 H12 O6 + 602 -- 6H2O + 6C02, How many moles of oxygen will it take to consume 3.9 moles of gluco
Mamont248 [21]

Answer:

The answer to your question is 23.4 moles of Glucose

Explanation:

Data

moles of Oxygen = ?

moles of glucose = 3.9

-Balanced chemical reaction

           1C₆H₁₂O₆  +  6O₂   ⇒   6H₂O  +  6CO₂

Process

1.- To solve this problem, use the coefficient of the balanced chemical equation, and use proportions and cross multiplication.

           1 mol of C₆H₁₂O₆ -------------------- 6 moles of O₂

    3.9 moles of C₆H₁₂O₆ ------------------   x

                                  x = (3.9 x 6 ) / 1

                                  x = 23.4 moles

2.- Conclusion

3.9 moles of glucose consume 23.4 moles of oxygen
