The equation for density, d, is
ss7ja [257]

<u>Answer:</u> The density of substance is 3.38g/cm^3

<u>Explanation:</u>

To calculate density of a substance, we use the equation:

\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}

We are given:

Mass of substance = 61.6 g

Volume of substance = 18.2cm^3

Putting values in above equation, we get:

\text{Density of substance}=\frac{61.6g}{18.2cm^3}\\\\\text{Density of substance}=3.38g/cm^3

Hence, the density of substance is 3.38g/cm^3

Identify the reactants in the equation: 6C0, + 6H2O - CHUO+ 60,
Effectus [21]

Answer:

The correct answer is d. 6H20 + 6CO2.

The reactant in the chemical reaction 6H2O + 6CO2 ---> C6H12O6 + 6O2 is 6H20 + 6CO2. Remember that the reactant is always at the left side of the equation. So the correct answer is 6H20 + 6CO2 since it's in the left of the equation. I hope this answer helped you.

How many atoms of carbon are represented in 3CH3CH2O?<br><br> 2<br><br> 4<br><br> 6<br><br> 8
GenaCL600 [577]

Answer: 6



Explanation:


1) The structure shown is:


3CH₃CH₂O


2) The molecule is CH₃CH₂O. The chemical formula is CH₃CH₂O. The subscripts indicate the number of atoms of the corresponding atom in each molecule.


Then, there are 1 + 1 = 2 atoms of C, 3+ 2 = 5 atoms of H, and 1 atom of O.


3) The number in front of the molecule is the coefficient. It is 3, and it tells the number of molecules.


So, there are 3 molecules, which means that you have 3 times a many atoms as calculated previously.


That is 3×2 = 6 atoms of C, 3 × 5 = 15 atoms of H, and 3 × 1 = 3 atoms of O.


Then, the number of atoms of carbon (C) in 3 molecules is 6
