Ivenika [448]3 years ago
4 0
The mole fraction of a product is the number of moles of the product divided by the total number of moles of the solution.

Here moles of methanol = 6.0 moles

Moles of solution = 6.0 moles of methanol + 3.0 moles of water = 9.0 moles of solution

Mole fraction of methanol = 6.0 / 9.0 = 0.67

Answer: 0.67

Which of the following statements best compares geothermal energy and the energy from natural gas based on their rates of renewa
pentagon [3]

Answer: Natural gas has a faster rate because, being a carbon resource, it quickly replenishes as part of the carbon cycle.

Explanation:

Natural gas is a natural gas which consists of mixtures of hydrocarbons. It is primarily composed of methane, alkanes, small percentage of nitrogen, hydrogen sulfide, helium and carbon dioxide.  

Being a carbon source it can be replenished easily due to decomposition of organic matter generated after the decomposition of dead animal and plant matter.  

The geothermal energy can be define as the energy obtained from the hot springs it includes the water that includes the thermal energy generate through heat present in the geosphere.  

Although the geothermal energy is the renewable source of energy but the time and period of it's generation remains unknown from the hot spring. Therefore, the rate of renewal of energy of natural gas is faster than the geothermal energy.

Heating a carboxylic acid with a primary amine forms water along with what organic product? OA) A secondary amide OB) A primary
Bezzdna [24]

Answer:

A) secondary amide

Explanation:

When carboxylic acid reacts with a primary amine, a condensation reaction takes place with the elimination of a water molecule .

For example, ethanol reacts with methylamine which is a primary amine gives N-Methylacetamide and a water molecule as:

CH_3COOH+NH_2CH_3\rightarrow CH_3-CONH-CH_3+H_2O

The bond formed which is

  O

   ||

-- C  ---NH ---

is known as secondary amide group as only one hydrogen is attached to nitrogen atom in the amide bond.
