Answer:
The given statement is true.
Explanation:
The given statement is true.
As per an estimate, to convert graphite into diamond nearly 1 billion to 3.3 billion years of time is required.
Graphite converts into diamond when high-pressure is applied deep in the earth core.
Nitrous oxide (N2O), also called dinitrogen monoxide, laughing gas, or nitrous, one of several oxides of nitrogen, a colourless gas with pleasant, sweetish odour and taste, which when inhaled produces insensibility to pain preceded by mild hysteria, sometimes laughter.

In order to measure 0.733 moles of KBr from a 3.00 M solution, the chemist needs 244 mL of solution.
<h3>What is molarity?</h3>
Molarity (M) is a unit of concentration of solutions, and it is defined as the moles of a solute per liters of a solution.
- Step 1: Calculate the liters of solution required.
A chemist has a 3.00 M KBr solution and wants to measure 0.733 moles of KBr. The required volume is:
0.733 mol × (1 L/3.00 mol) = 0.244 L
- Step 2: Convert 0.244 L to mL.
We will use the conversion factor 1 L = 1000 mL.
0.244 L × (1000 mL/1 L) = 244 mL
In order to measure 0.733 moles of KBr from a 3.00 M solution, the chemist needs 244 mL of solution.

Given:
The Kp for the reaction below is 1.49 · 10⁸ at 100.0°C (a balanced reaction)
In an equilibrium mixture of the three gases.
p CO = p Cl₂ = 2.22 · 10⁻⁴ atm.
Question:
The partial pressure of the product, phosgene (COCl₂), is __ atm.
The Process:
Let us write the equilibrium constant in terms of pressure based on the reaction above.
We set p COCl₂ as the subject to be asked.
Substitute all the data above into the equation.
Thus, the partial pressure of the product, phosgene (COCl₂), is 7.34 atm.
