Answer:
INTENSIVE PROPERTY OF MATTER
Explanation:
DENSITY IS AN INTENSIVE PROPERTY OF MATTER THAT ILLUSTRATES HOW MUCH MASS A SUBSTANCE HAS IN A GIVEN AMOUNT OF VALUE,
The pressure of the tyre after the temperature change is 0.89atm. Details about pressure can be found below.
<h3>How to calculate pressure?</h3>
The pressure of the tyre can be calculated using the following equation:
P1/T1 = P2/T2
Where;
- P1 = initial pressure
- P2 = final pressure
- T1 = initial temperature
- T2 = final temperature
According to this question, a tyre at 21°C (294K) has a pressure of 0.82 atm. Its temperature decreases to –3.5°C (269.5K).
0.82 × 294 = P2 × 269.5
241.08 = 269.5P2
P2 = 241.08 ÷ 269.5
P2 = 0.895atm
Therefore, the pressure of the tyre after the temperature change is 0.89atm.

The half reaction that occur at the anode is
Zn (s)→ Zn²⁺ (aq) + 2e⁻
<u><em> Explanation</em></u>
- In galvanic cell oxidation take place at the the anode. That is there is lost of electrons at the anode.
- Zn loss two(2) electron to form Zn²⁺ ion.
- Zn is therefore oxidized since it's oxidation move from oxidation state 0 to oxidation state 2+.
Answer:
Natural gas
Explanation:
Natural gas is a gaseous fossil fuel produced from organic matter that is used to heat homes and cook food.
Natural gas is one of the most volatile part of hydrocarbons that exist together with fossil fuel.
- In a reservoir, natural gas is usually on top of the fossil fuel reserve.
- It can also be distilled from crude oil as they rises up on top of the column first due to their low boiling point
- The gas mixture is made up light hydrocarbons from methane to hexane.
