Can I+ (the iodine cation) becalled a Lewis base?<br> Fullyexlplain your answer.
Alenkinab [10]

Answer: No I+ cannot be called a Lewis base.

Explanation:

According to Lewis Theory, it defines an acid as an electron-pair acceptor and a base as an electron-pair donor.

In terms of Lewis basicity, Iodide ion (anions) has the more readily available lone pair electrons for donation since iodide ion is less electronegative .

With the help of the net electronic structure one can understand the answer of the question, because we need to study the I+  ion (cation) structure.

Lewis acid is therefore any substance, that can accept a pair of nonbonding electrons. 

From the picture below I+ is most likely ready to accept electrons not to give from it 5s orbital to become stable.

Which substance absorbs 58.16 kJ of energy when 3.11 mol vaporizes? a)CH4 b)H2S c)CO2 d)NaCl
schepotkina [342]

Answer:

H_2S

Explanation:

Given the amount of heat absorbed and the amount of substance in moles, we may calculate the heat of vaporization. Heat of vaporization is defined as the amount of heat per 1 mole of substance required to evaporate that specific substance.

Based on the value of heat of vaporization, we will identify the substance. Firstly, let's calculate the heat of vaporization:

\Delta H^o = \frac{58.16 kJ}{3.11 mol} = 18.7 kJ/mol

Secondly, let's use any table for heat of vaporization values for substances. We identify that the heat of vaporization of H_2S is 18.7 kJ/mol

3) How Many moles are in 0.500 milligrams of the “emergency” hormone, adrenaline, whose formula
Yuki888 [10]
To determine the total number of moles that are in the hormone, you would simply convert that to grams and then use the molar mass if the formula to solve for the total number of moles in the compound.

Explain the term conservation of mass
emmasim [6.3K]

The term conservation of mass means that mass in any system can neither be created nor destroyed but can be transformed from one state to another.

<h3>What is the law of mass of conservation?</h3>

The law of conservation states that the mass in an isolated system can neither be created nor be destroyed but can be transformed from one form to another.

This means that when an element is involved in a chemical reaction, it's mass remains the same at the end of that reaction.
