A coefficient is the number or letter before the variable. The variable is the unknown value.
H2O is also know as water
All of the various light
waves move with the same speed, a value
<span>abbreviated (c) equal to 3.00
× 108 m/s. The frequency ([1]) that light waves
pass a given point is</span>
measured in waves/second or
simply ‘per second’ (1/s).
the frequency of the wave f =
(3.00 × 10^8 m/s)/ 2.340 m
<span>f = 1.28x10^8 Hz</span>
Answer:
BaCl₂ and H₂SO₄
Explanation:
The reaction is the precipitation of BaSO₄ from solution.
This means that our reactants must contain the Ba ion and SO₄²⁻ ion. The reactants that meet this criteria are the; BaCl₂ aand H₂SO₄
The reaction is given as;
BaCl₂ + H₂SO₄ --> BaSO₄ + 2HCl
