If one molecule of glucose (C6H120) reacts completely with three molecules of oxygen (O2), what is the TOTAL number of atoms

nalin [4]

Answer : The total number of atoms in the product are, 36 atoms.

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

When 1 molecule of glucose reacts completely with 3 molecules of oxygen then it react to give 6 molecules of carbon dioxide and 6 molecules of water.

The balanced chemical reaction will be:

$C_6H_{12}O_6+6O_2\rightarrow 6CO_2+6H_2O$

There are 3 atoms in carbon dioxide and 3 atoms in water.

Total number of atoms in the product = 6(3) + 6(3) = 36 atoms

Thus, the total number of atoms in the product are, 36 atoms.

Is the law of conservative mass observed in this equation CaCO3 + 2HCI -->CaCI2 +H2O + CO2

pychu [463]

Answer:

The law is observed in the given equation.

Explanation:

CaCO₃ + 2HCI → CaCI₂ +H₂O + CO₂

In order to find out if the law of conservative mass is followed, we need to <u>count how many atoms of each element are there in both sides of the equation</u>:

Ca ⇒ 1 on the left, 1 on the right.

C ⇒ 1 on the left, 1 on the right.

O ⇒ 3 on the left, 3 on the right.

H ⇒ 2 on the left, 2 on the right.

Cl ⇒ 2 on the left, 2 on the right.

As the numbers for all elements involved are the same, the law is observed in the given equation.

What causes a top to stop spinning?

lina2011 [118]

Tops stops spinning because it doesn't have energy or ran out of force for example when you spin a top you give force to it then after 30 sec it going to stop going slower and slower that Is losing energy that's how tops stops spinning

An object has a mass of 4 grams and a volume of 2 cm^3.what is the density of the object?

stellarik [79]

Answer:

2.0 grams per cubic centimeter

Explanation:

(You can refer to the DMV triangle to help you solve this!)

Density = Mass/Volume

Density = 4.0g/2.0cm3

Density = 2.0g/cm3

Hope this helps!!!
