Asubstance is followed by the symbol (l) in a chemical equation. what does the symbol represent?

B - The substance is in the liquid state

Explanation:

The symbols for the states of matter in Chemistry are as follows:

(aq) aqueous or dissolved in water

(g) gas

(s) solid

(Δ) yields heat

(l) liquid

Thus, if the symbol that follows is (l), then that means that the element is in a liquid state.

I copied this from another user on and it is correct. Enjoy the answer and remember Jesus Christ, our Lord and savior loves YOU!! God bless guys.

- The symbol (l) stands for liquid phase.

Explanations:- In chemical equations, the symbols like (s), (l), (g) and (aq) are used to represents the physical states of the elements or compounds.

(s) stands for solid, (l) stands for liquid, (g) stands for gas and (aq) stands for aqueous.

For example:-

This is the balanced equation for water formation from hydrogen and oxygen gases. (g) is written next to both hydrogen and oxygen which indicates both of these elements are gases. (l) is written next to that indicates it is liquid.

So, the symbol (l) in a chemical equation represents a liquid state of the substance.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
