Answer:
1) Lithium + chlorine → Lithium chloride
2) Li + Cl₂ → LiCl
Explanation:
Skeleton equation:
Li + Cl₂ → LiCl
Skeleton equation with physical states:
Li(s) + Cl₂(g) → LiCl(s)
Balanced equation:
2Li(s) + Cl₂(g) → 2LiCl(s)
Word equation:
Lithium + chlorine → Lithium chloride
When solid lithium react with gaseous chlorine it form lithium chloride. The oxidation state of lithium is +1 while that of chlorine is -1. Thus one atom of lithium and one atom of chlorine are combined to make overall compound neutral and both are in stable state.
The atomic number of an element tells you how many protons each atom has. Losing an electron won't affect the number of protons. It will, however, change the charge on the atom. Protons are positive and electrons are negative. If there's more positive than negative then the atom has a positive charge. So the charge for the sodium atom would be +1
Answer:
False
Explanation:
An object's velocity can be described by it's direction. Because velocity is a vector. Besides velocity and acceleration are different units they can't be described by each other.
Explanation:
Molecular formula for Propene = C3H6
The isomer of propene is cyclopropane.
(Draw a triangle to show that it is cyclopropane)
The statement which describes the potential and the kinetic energy of the water is this: THE POTENTIAL ENERGY INCREASES AND THE AVERAGE KINETIC ENERGY REMAINS THE SAME.
At boiling point of water, the heat that is been added to the water is used to break the chemical bonds that holds the molecules of the water together so that they can turn into vapour. At this point, the average kinetic energy of the water remains the same while the potential energy increases.
