Write the balanced equation for the reaction given below: C2H6 + O2 --> CO2 + H2O. If 16.4 L of C2H6 reacts with 0.980 mol of O2, how many liters of carbon dioxide gas will be produced? What is the limiting reagent? How many oxygen atoms will be in this sample of carbon dioxide? How many moles of the excess reactant will be left over? How many grams of the excess reactant will be left over?

Answers

Answer 1

Answer: The balanced reaction: C2H6 + 7/2 O2 -> 2 CO2 + 3 H2O

We first convert volume of C2H6 to no. of moles. We use the conditions at STP where 1 mol = 22.4 L thus,

Moles C2H6 = 16.4 L/ 22.4 L =0.7321 mol

In order to determine the limiting reagent, we look at the given amounts of the reactants.

0.7321 mol C2H6 (7/2 mol O2 / 1 mol C2H6) = 2.562 mol O2

From the given amounts of the reactants, we can say that O2 is the limiting reactant since we need 2.562 mol O2 to completely react the given amount of C2H6. The excess reagent is C2H6

To calculate for the amount of products and excess reactants:

0.980 mol O2 (2 mol CO2 / (7/2 mol O2)) = 0.56 mol CO2 (22.4 L / 1 mol ) =12.544 L CO2
0.980 mol O2 (1 mol C2H6 / (7/2 mol O2)) = 0.28 mol C2H6
Excess C2H6 = 0.7321 mol - 0.28 mol C2H6 = 0.4521 mol C2H6

We then use the molecular weight of C2H6 to convert the excess amount to grams.

0.4521 mol C2H6 (30.08 g C2H6 / 1 mol C2H6) = 13.60 g C2H6

Since the limiting reagent is O2 there will be no oxygen atoms that will be left after the reaction.

How does latitude affect a climate zone?(A) Climate zones at low latitudes are hotter because they receive more direct sunlight.

(B) Climate zones at high latitudes are cooler because they are closer to the equator.

(C) Climate zones at high latitudes receive a lot of precipitation because they are farther from the equator.

(D) Climate zones at low latitudes receive little precipitation because they are closer to the ocean.

Answers

(A) Climate zones at low latitudes are hotterbecause they receive more direct sunlight. This is because the Earth's surface at the equator is closer to the sun and therefore receives more direct sunlight

Additionally, the distance of a region from the equator affects its precipitation pattern, with regions closer to the equator generally receiving more precipitation than regions at higher latitudes.

As a result, the tropics, which lie near the equator, tend to be warmer than other regions. In contrast, regions at high latitudes receive less direct sunlight due to the curvature of the Earth's surface, resulting in colder temperatures.

In a 0.01 M solution of HCl, Litmus will be

Answers

In a 0.01 M solution of HCl, Litmus will be red. Litmus paper will turn into red in acidic conditions. Hydrochloric acid is an acid. Litmus is an indicator for acidity and alkalinity made from inchens.

Explanation:

A solution with pH less than 7 will be acidic in nature and it will change color of blue litmus into red.

For example, HCl is a strong acid as it dissociates to give hydrogen ions and chlorine ions.

A solution with pH more than 7 will be basic in nature and it will change color of red litmus into blue.

A solution with pH equal to 7 will be neutral in nature and it will not change the color any litmus paper.

Thus, we can conclude that in a 0.01 M solution of HCl, litmus will be red.

A particle has 5 protons, 6 neutrons, and 5 electrons. What is its net charge.

Answers

It would have a zero charge because it is a neutral atom. The number of electrons which is a negative charge is equal to the number of protons which is positive, they will cancel each other out hence meaning it will become neutral

Which is a product of a condensation reaction? 1. O2 2. CO2 3. H2 4. H2O

Answers

The correct answer is H2O, it is a product of a condensation reaction. It is a type of chemical reaction where two molecules combine to form a larger molecule together with a loss of a small molecule. Usually, this small molecule is water.

Answer:

$H_(2)O$ is a product of a condensation reaction.

Explanation:

In a condensation reaction, two molecules are combined to produced a large molecules along with removal of a water molecule.

For an example, let's consider aldol condensation reaction.

In aldol condensation reaction, an enolate anion reacts and combines with an aldehyde or ketone molecule follwed by dehydration. In that dehydration step , $H_(2)O$ gets removed and an unsaturated carbonyl product is formed.

Usually, $O_(2),CO_(2) and H_(2)$ are produced as a by product of a decomposition reaction.
