2p + 8 = -2p what is p

p = -2

Step-by-step explanation:

Start by subtracting 2p from both sides to get 8 = -4p. Divide both sides by -4 to get -2 = p

-2

Step-by-step explanation:

2p+8= -2p

Subtract 8 from both sides:

2p+8-8= -2p -8

Simplify:

2p= -2p-8

Add -2p to each side:

2p+2p= -8

Simplify:

4p= -8

Divide by 4:

p= -2

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:
