Ionic compounds conduct electricity when dissolved in water, because the dissociated ions can carry charge through the solution. Molecular compounds don't dissociate into ions and so don't conduct electricity in solution. Electrical conductivity of the compound in liquid form
Answer: it reacts with the alkali metals (M) to form a salt MX, where X is the halogen.
Explanation: Group 7A elements are halogen and they react with alkali metals like Sodium or potassium to form a salt like NaCl
Answer: Gravity.
Explanation:
Earth and other objects would have fly off into space in a straight line if there would have been no gravity in between objects.
The gravity can be defined as the force between two objects in space which keeps two objects together in the space.
It is also responsible for holding the objects in space, making them move on their orbits, not allowing the heavenly bodies to crash.
So, there would be no gravity the objects will fall off in a straight line and none of the objects would be at its specified position.
A hypothesis
-Can be tested
-Is a prediction about the expected outcome of an experiment
-Must be stated in a form that can be either proven or disproven
Your answer is D: All of the above are true
+protons and -electrons because they would eventually equal out.
