Answer:
C
Explanation:
Single replacement reactions is when only one element gets replaced / changed. This usually looks like this: A + BC = B + AC or A + BC = C + AB
Therefore, the number of reactants must be equal to the number of products, since no actual combinations / break ups are occurring.
Answers A and D are eliminated right away since the number of products don't equal the number of reactants.
Answer B is wrong because it does not show simply one element being replaced, instead, two compounds are being formed. It doesn't look like the example given.
Only answer C shows that one element is replaced:
The iodine is replaced with bromine to form NaBr + I2
I believe it is is
1. Biomass is burned
2. water boils to steam
3. Steam turns a turbine
4. Turbine powers generator
5. Generator produces electricity
Since the prefix "centi" means hundredth, we can assume one ant is going to take up one hundredth of the length. Since multiplying anything by 1 (e.g. 2 * 1 = 2) equals that number, we can "multiply" 100 by 1 to get 100
