Answer:
The atomic number equals number of protons and electrons
This is true when an atom is in neutral state.
The correct answer is C. As heated material gets closer to the surface, it begins to cool.
Explanation:
Convection currents involve the flow and movement of particles in gases or liquids due to changes in temperature and density. This occurs on the Earth's mantle, which is partially liquid and it is located between the core (center of Earth) and the crust composed of plates.
In this way, molten material that is near the core heats and rises as it is less dense, but once it reaches the crust it cools, and after some time it sinks again as the magma increases its density. This cycle is constant and causes the movement of the plates in the crust, that might move apart or toward other plates. According to this, the only accurate statement is "As heated material gets closer to the surface, it begins to cool".

Answer: The molarity of silver nitrate in the diluted solution is 0.015 M
Explanation:
Molarity of a solution is defined as the number of moles of solute dissolved per Liter of the solution.
According to the dilution law,
where,
= molarity of concentrated solution = 0.150 M
= volume of concentrated solution = 10.0 ml
= molarity of diluted solution = ?
= volume of diluted solution = 100.0 ml
Thus the molarity of silver nitrate in the diluted solution is 0.015 M
