Answer: B. Heptane

Explanation:

Saturated hydrocarbons are defined as the hydrocarbons in which a single bond is present between carbon and carbon atoms. they are known as alkanes. The general formula for these hydrocarbons is C_nH_{2n+2}

Unsaturated hydrocarbons are defined as the hydrocarbons which have double or triple covalent C-C bonds. They are known as alkenes and alkynes respectively. The general formula for these hydrocarbons is C_nH_{2n} and C_nH_{2n-2}

A. Nonyne is an alkyne with 9 carbon atoms with molecular formula of C_9H_{16}

B. Heptane  is an alkane with 7 carbon atoms with molecular formula of C_7H_{16}

C. Ethyne is an alkyne with 2 carbon atoms with molecular formula of C_2H_{2}.

D. Hexene is an alkene with 6 carbon atoms with molecular formula of C_6H_{12}

9.31g is the same mass as ?
Dmitry_Shevchenko [17]

Answer:

9.31 g = 0.00931 kg

Explanation:

We need to tell that 9.31 gram is same as what. There are many units that measure the meass of an object like milligram, kilogram, centigram etc.

The relation between kilogram and gram is as follows :

1 kg = 1000 g

or

1 g = 0.001 kg

If we change 9.31 gram to kg, we get :

9.31 g = (9.31 × 0.001) kg

or

9.31\ g=9.31\times 10^{-3}\ kg\\\\=0.00931\ kg

Hence, 9.31 g is the same mass as 0.00931 kg.

What is true of the total mass of reactants compared to the total mass of products
kaheart [24]

Answer:

The total mass of reactants equals the total mass of products  

Step-by-step explanation:

The <em>Law of Conservation of Mass</em> states that matter cannot be created or destroyed in a chemical reaction:

Reactants ⟶ products

Thus, if you start with a given mass of reactants, the total mass of products will equal the total mass of reactants.
