Answer:
The molar mass of any substance is the mass in grams of one mole of representative particles of that substance. ... In such a conversion, we use the molar mass of a substance as a conversion factor to convert mole units into mass units (or, conversely, mass units into mole units).
Explanation:
Answer : The correct option is B.
Explanation :
The temperature of the warm water is higher than the cold water. That means as the temperature of warm water increases, the kinetic energy of the warm water molecule also increases.
As the kinetic energy of the warm water molecule increases, the number of molecules conversion into a vapor also increases (i.e, quick evaporation), thereby increasing the vapor pressure of warm water.
Hence, the correct answer is, (B) Warm water evaporates more quickly.
Answer:
A. C(s) + O2(g) → CO2(g) + 393.5 kJ
Explanation:
The formation of carbon IV oxide (CO2) is an exothermic process. n exothermic process is a chemical process in which heat is evolved. Speaking in lay man's terminology, heat is one of the 'products' of the reaction. This implies that heat is evolved by the process.
The formation of CO2 is always a combustion reaction where heat is evolved or released by the reaction system. Hence the reaction could be shown as;
C(s) + O2(g) → CO2(g) + 393.5 kJ
This implies that 393.5 kJ of energy is released in the reaction in the form of heat. Hence the answer given in the answer box.

Hydroboration addition of borane to a compound across the double bond.
<h3>What is hydroboration?</h3>
The reaction that is called hydroboration could be carried out with an alkene or an alkyne as the case maybe. In each case, the reaction involves the addition of borane to a compound across the double bond. The reaction could further proceed to produce an alkanol.
Let us restate that like most of the organic reactions, this reaction occurs in a sequence of steps and each step of the reaction has a way of bringing us closer to the end product of the entire steps of the reaction take in proper order
As shown in the image attached to this answer, the reaction was carried out in DMS in order to stabilize the borane. We have shown the borane to be a reactant as it adds across the double bond to yield the product.
