Explanation:
From the word equation, it shows that when copper oxide reacts with sulphuric acid, a double replacement reaction will occur, where copper and sulphate forms a bond with each other, and so do water.
Answer:
Organisms become more complex over time.
Explanation:
We all evolved from the first bacteria, which was relatively simple. We see over time that things become more adapted, slowly adding eyes, lungs, behavioral patterns, and consciousness.
A. Atoms of chlorine (Cl)
Explanation:
The atoms of chlorine are held together by non-polar covalent bonds.
- Covalent bonds are formed between two or more atoms having zero or very small electronegativity difference.
- For homonuclear molecules where the two bonding atom are of the same kind, the electronegativity difference is zero.
- This covalent bond type is called non-polar covalent bond.
- In this bond type, there is equal sharing of the electron pair between the atoms and there is no electrostatic charge on the molecule.

Answers are:
2. It pushes on all objects that are on Earth’s surface.
3. It can be measured in atmospheres or kilopascals.
Barometric pressure (atmospheric pressure), is the pressure within the atmosphere of Earth
Atmospheric pressure decreases with increasing height, because there are fewer air molecules above a given object.
Barometer is an instrument used in meteorology to measure atmospheric pressure.
Atmospheric pressure (atm) is the force per unit area by the weight of air above that point.
Kilopascal (kPa) is a metric system pressure unit and equals to 1000 force of newton per square meter.
Atmospheric pressure results from molecular collisions of atmospheric gases.
