How many moles of I2 will form 3.58 g of NI3?

Answers

1. The balanced chemical reaction is:

N2 +3 I2 = 2NI3

We are given the amount of product formed. This will be the starting point of our calculations.

3.58 g NI3 ( 1 mol NI3 / 394.71 g NI3 ) ( 3 mol I2 / 2 mol NI3 ) = 0.014 mol I2.

Thus, 0.014 mol of I2 is needed to form the given amount of NI3.

An Arrhenius acid has(1) only hydroxide ions in solution
(2) only hydrogen ions in solution
(3) hydrogen ions as the only positive ions in solution
(4) hydrogen ions as the only negative ions in solution

Answers

Answer: (3) hydrogen ions as the only positive ions in solution

Explanation: Arrhenius acids are substances which dissociate in water to give $H^+$ ions.

For example: $HCl$ is an Arrhenius acid.

$HCl\rightarrow H^++Cl^-$

Arrhenius bases are substances which dissociate in water to give $OH^-$ ions.

For example: $NaOH$ is an Arrhenius base.

$NaOH\rightarrow Na^++OH^-$

The answer is (3) hydrogen ions as the only positive ions in solution. One ionic compound must have positive ion and negative ion at the same time. The Arrhenius base has hydroxyl ion as only negative ions in solution.

Is the compound CO ionic or covalent

Answers

If a compound is made of one metal and one non-metal it's bond will be ionic, whereas if a compound is made of two non-metals, it's bond will be covalent.

C - Non-Metal
O - Non-Metal

CO = Covalent.

Calculate how much gasoline and money could be saved if the automobile's fuel efficiency were increased by 25%.Gasoline = 25 gallons per week
Money = $2 per gallon ($50 total)

Answers

In the question it is already given the amount of actual gasoline and money consumed before the fuel efficiency gets increased by 25%
Gasoline consumption before the increase in fuel efficiency = 25 gallons per week
Gasoline saved after the increase in fuel efficiency = [25 * (25/100)] gallons per week
= 6.25 gallons per week
So every week 6.25 gallons of gasoline can be saved after increasing the efficiency of the automobile by 25%.
Then
The amount of money saved against the 6.25 gallons of gasoline saved = (6.25 * 2) dollars
= 12.50 dollars
The amount of money saved is $12.50 per week.
