He conjugate pair for a weak acid is--

Answers

The stronger acid, however, is on the left side of the equation. The general rules suggest that the stronger of a pair of acids must form the weaker of a pair ofconjugate bases. The fact that HCl is a stronger acid than the H3O+ ion implies that the Cl- ion is a weaker base than water.

11x + 13
12x+6 Solve for x

Answers

Answer:

x = 7

Explanation:

Simplifying

11x + 13 = 12x + 6

Reorder the terms:

13 + 11x = 12x + 6

Reorder the terms:

13 + 11x = 6 + 12x

Solving

13 + 11x = 6 + 12x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-12x' to each side of the equation.

13 + 11x + -12x = 6 + 12x + -12x

Combine like terms: 11x + -12x = -1x

13 + -1x = 6 + 12x + -12x

Combine like terms: 12x + -12x = 0

13 + -1x = 6 + 0

13 + -1x = 6

Add '-13' to each side of the equation.

13 + -13 + -1x = 6 + -13

Combine like terms: 13 + -13 = 0

0 + -1x = 6 + -13

-1x = 6 + -13

Combine like terms: 6 + -13 = -7

-1x = -7

Divide each side by '-1'.

x = 7

Simplifying

x = 7

Answer:Simple and best practice solution for 11x+13=12x+6 equation. ... + 6 Reorder the terms: 13 + 11x = 6 + 12x Solving 13 + 11x = 6 + 12x Solving for variable 'x'.

Explanation:

The components of a longitudinal wave include __________.a. rarefaction only
b. compression only
c. compression and rarefaction
d. compression, rarefaction, and triangulation

Answers

The correct answer to the question that is stated above is letter C.compression and rarefaction

Longitudinal wave has two features which include:
A compression-- the part of the wave which is pressed together.
A rarefaction-- the part of the wave that is the most spread apart.

The sign of ΔHrxn and ΔSrxn for several different reactions are given.In which case is the reaction spontaneous at all temperatures?
ΔHrxn<0; ΔSrxn>0ΔHrxn<0; ΔSrxn<0ΔHrxn>0; ΔSrxn<0ΔHrxn>0; ΔSrxn>0

Answers

The answer is ΔSrxn>0 and ΔHrxn<0

This is because of the thermodynamic equation of the Gibbs Free Energy given by:

ΔG = ΔH – TΔS

First, it is important to note that spontaneous reactions are usually given by ΔG <0, ΔH<0 and ΔS>0. However, ΔG is the most important identifier of a thermodynamic process, so it is best to figure out the conditions that would give a negative ΔG.

For the equation's first term (ΔH), ΔG decreases when ΔH is decreased. For the second term TΔS, it can be observed that ΔG decreases when TΔS is increased due to the negative or minus sign.

So for all temperatures, ΔG is kept negative if ΔH is negative and TΔS is positive (because of the negative sign).
