Explanation:
For multiplication or division, the rule is to count the number of significant figures in each number being multiplied or divided and then limit the significant figures in the answer to the lowest count.
a. 20.0 meters x 0012.65 meters
The numbers are;
20.0 (3 s.f) and 12.65 (4 s.f)
The multiplication gives; 253
Since 253 is already in 3 s.f, that's the answer.
b. 002.5 × 103 meters + 3.50 × 102 meters
The numbers are;
002.5 (2 s.f), 103 (3 s.f), 3.50 (3 s.f) and 102 (3 s.f)
002.5 × 103 = 257.5 = 260 (2 s.f)
3.50 × 102 = 357 = 360 (2 s.f)
260 + 360 = 620
No
1. I know it
2. If you watch the odd1sout, he did a science project about this and it had LITERALLY NO EFFECT
27g of 's × 1 mole/32.065g equals 0.84
13.4g of o × 1 mole/16g equals 0.83
Divide all these by the smallest number then round to the nearest number.
Explanation:
A reversible reaction is a reaction which results in the formation of products which gives back reactants. Therefore, it is said that a reversible reaction occurs in both forward and backward direction.
Thus, it can be concluded that a reversible reaction is a reaction that takes place in the both directions . If the reaction were to equilibrium, the rate of the forward reaction would equal that of the reverse reaction.equilibrium.
