A solution has a [OH-] = 8.6 x 10-5. Answer the following questions.

pOH =
pH =
[H+] =

Answers

Answer 1
Answer:

Answer: pOH= 4.06

pH= 9.94

[H^+]=1.14* 10^(-10)M

Explanation: pOH is the negative logarithm of OH^- concentration.

pH is the negative logarithm of H^+ concentration.

pOH=-log[OH^-]

pOH=-log[8.6* 10^(-5)]=4.06

2) pH+pOH=14

pH=14-4.06

pH=9.94

3) pH=-log[H^+]

9.94=-log[H^+]

[H^+]=1.14* 10^(-10)M
Answer 2
Answer: pOH = 4
pH = 10
[H+] = 1 X 10^-10

Answer:

Selenium (Se)

Explanation:

To identify an element, we look at its number of protons.

We are given 32 protons, so the 32nd element of the Periodic Table is Selenium (Se).

How many degrees Celsius is 871.09 Kelvin? Round your answer to two decimal places.

Answers

To convert Kelvin to Celsius, you need to subtract 273.15 from the given value. Let's perform the conversion:

871.09 Kelvin - 273.15 = 597.94 degrees Celsius

Therefore, 871.09 Kelvin is approximately equal to 597.94 degrees Celsius when rounded to two decimal places.

The temperature of 871.09 Kelvin as stated in the question is approximately -101.06 degrees Celsius.This is obtained by the standard result.

Temperature is often measured in two main scales, Kelvin (K) and Celsius (°C). To convert from Kelvin to Celsius, you need to subtract 273.15 from the given temperature in Kelvin.

This adjustment accounts for the fact that 0 Kelvin (absolute zero) is the point at which all molecular motion theoretically stops, while 0 degrees Celsius is the freezing point of water.

In this case, for the temperature of 871.09 Kelvin, the conversion is as follows:

The temperature in Celsius = 871.09 K - 273.15 ≈ -101.06°C.

This means that a temperature of 871.09 Kelvin is approximately equivalent to -101.06 degrees Celsius. It's important to note that Kelvin is an absolute temperature scale, where 0 K represents absolute zero, while Celsius is a relative scale with 0°C corresponding to the freezing point of water at standard atmospheric pressure.

Adding solvent or removing solute from a soltuion is called __________, and a solution is said to be _______________ if it has more solute.

Answers

Adding solvent or removing solute from a solution is called diluting. And a solution is said to be concentrated if it has more solute. The opposite of diluting is called concentrating. The measure of the amount of solute in a solution is expressed in concentration.

How many phosphorus atoms are there in 1.75 mol of calcium phosphate,
Ca3(PO4)2

Answers

There will be two atoms of phosphorus in the 1.75 mol of calcium phosphate.

What are atoms?

Atoms are the smallest unit of matter. In a chemical reaction, the number of atoms shows the quantity of an element in the compound or reaction. Phosphorus is a chemical element that is preset in the periodic table.

In calcium phosphate, Ca3(PO4)2, the number of atoms can be calculated by counting the number of moles that is given in the equation.

The number of atoms of calcium is 3, and the number of phosphorus atoms is 2.

Now given the 1.75 mol of calcium phosphate, so the number of atoms of phosphorus will be the same in any number of moles of calcium phosphate. So there will be 2 atoms of phosphorus in the given equation.

Thus, the number of atoms is two.
