A, because a synthesis reaction is A+B—> AB
B is a decomposition AB—> A+B (opposite of synthesis)
C is acids and base acid 1 + base 1 —> acid 2 + base 2
D is double displacement AB+CD —> AD+CB
A is correct. Potential energy decreases and turns into kinetic energy.
They are made up of chains of Hydrogen and c) Carbon
Chemical equilibrium is a condition where the rate of product made is same as the rate of reactant made. Since the reaction to the left is same as the reaction to the right, so the amount of reactant and product will not be changed (doesn't mean that the amount is same, it just won't increase or decrease).
It's called equilibrium since there will be no change in their amount.
Answer:
C. 1:30
Explanation:
The toy car is .5 feet long and the actual car is 15 feet long
This gives you a ratio of
.5:15
Now for everything you have to remember this
.5:15
=1:30
=2:45
=3:60
C is the only answer that matches any of the ratios above.
Even if you went farther in the ratios none of them would match this ratio.
Hope this helped.
