Answer:
0.014 M/s
Explanation:
The rate of a chemical reaction is defined as the change in the concentration of the products or reactants over a specific period of time. The reaction rate can be calculated by dividing the change in concentration of the reactants products by the time elapsed for the given reaction. The reaction rate can also be calculated bu using:
![r = k*[CH_{3}Br]*[NaOH]](https://tex.z-dn.net/?f=r%20%3D%20k%2A%5BCH_%7B3%7DBr%5D%2A%5BNaOH%5D)
where:
r is the rate of the reaction, k is the rate constant, and [] signifies the concentration of the compound.
When the concentrations of 
and NaOH are both 0.140 M, the rate of the reaction is 0.0070 M/s.
Therefore, when the concentration of is doubled, the rate of the reaction will also be doubled, i.e. r = 2* 0.0070 = 0.014 M/s
1. Hybridization is a method of sexual reproduction whereas cloning is a method of asexual reproduction.
2. Hybrid animals are sterile, but cloned animals are fertile.
3. Hybrid organisms contain DNA from both male and female parents but cloned organisms contain DNA from only one type of parent.
4. Hybrid has superior character over its parents (improved hybrid vigor) but clones are 100% identical to their parent.
5. Hybridization gives only one hybrid progeny, whereas through cloning unlimited identical organisms can be produced.
Answer:
C. Lithium is most easily oxidized of the metals listed on the activity series and therefore it will most easily give electrons to metal cations
Explanation:
"Lithium" is a type of alkali metal that has a "single valence electron." Since it is a reactive element, it easily gives up an electron when it is combined with other elements. Such giving up of electron is meant to create compounds or bonds.
Among the common metals listed, "lithium" is the most easily oxidized. This means that it donates its electrons immediately. Such combination makes it exist as a<em> "cation"</em> or <em>"positively-charged."</em>
So, this explains the answer.

Answer: 160.40 g Fe2O3 are needed.
Explanation:
Balanced equation: 2 Al + Fe2O3 —> Al2O3 + 2Fe
54.2 g Al * 1 mol Al / 26.98 g Al * 1 mol Fe2O3 / 2 mol Al * 159.69 g Fe2O3 / 1 mol = 160.40 g Fe2O3 are needed.
