Hi,
The answer is +2, since there are 10 positive charges (protons) and 8 negative charges (electrons), so 10(+1) + 8(-1)= +10 -8= +2.

If my answer was not clear enough or you’d like further explanation please let me know.
Hope this helps!

The charge of 1 proton is +1 and the charge of one electron is -1
So you multiply by how many you have and add by the number of protons by the number of electron because you want to find the total charge and even if one electron has a negative charge you still need to include it
10(+1)+8(-1)
10-8
+2

Gasoline is used to power most of the cars in the United States and worldwide. The average fuel economy for a gasoline powered c

kotegsom [21]

Answer:

469 gallons

Explanation:

From the question given, we were told that:

For every 32 miles, 1 gallon of gasoline is consumed.

With the above information, we can obtain the number of gallon of gasoline consumed by a car per year i.e 15000 miles

This is illustrated below:

If 32 miles consumed 1 gallon of gasoline,

Therefore, 15000 miles will consume = 15000/32 ≈ 469 gallons of gasoline.

Therefore, 469 gallons of gasoline is consumed by the average car each year

What is the name of this compound? 2-butanone 2-pentanone 4-pentanone 4-butanone

UkoKoshka [18]

Answer:

2-pentanone

Explanation:

The oxygen atom is attached to the 2nd carbon atom in the longest linear chain, thus the prefix 2. the longest continuous carbon chain has five carbon atoms giving it the prefix pent-. the chemical is a ketone thus the suffix none.

blagie [28]

Answer:

The answer to your question is K = 1.48

Explanation:

Balanced chemical reaction

Br₂ + I₂ ⇒ 2IBr

Process

1.- Calculate the concentration of each of the reactants

[Br₂] = 0.6 mol / 1 L

= 0.6 M

[I₂] = 1.6 mol / 1 L

= 1.6 M

[IBr] = 1.19 M

2.- Write the equation of the Equilibrium constant

K = [IBr]² / [Br₂][I₂]

-Substitution

K = [1.19]² / [0.6][1.6]

- Simplification

K = 1.4161 / 0.96

- Result

K = 1.48

Why are pure liquids and solids not included in the reaction quotient or the equilibrium constant expression for a given heterog

AfilCa [17]

Pure liquids and solids at the equilibrium stage:

Pure solids and pure liquids are not included in expressions for the equilibrium constant of heterogeneous equilibria since their concentrations are constant across time. Therefore, including it in our equilibrium expression is not significant.

Equilibrium expression:

When a certain chemical reaction is in equilibrium, the rates of the forward and backward reactions are equal, which means that there is no net change in the concentrations of the reactants and products and that the reaction mixture's composition does not change.

The concentration of solid and liquid:

Solid or liquid concentration,

= No. of Moles/ Volume in L

= Mass/(Volume × molar mass)

= Density/ Molar mass

Pure solids and liquids have constant densities and molar masses at a constant temperature.

Because of this, they have constant molar concentrations, which means that they are not considered in the equilibrium constant for a heterogeneous reaction.
