Answer:
A. your reaction makes more products.
Explanation:
This is a fun question dealing with idea of Le Chatelier's principle.
In an exothermic reaction, you produce heat. This means that heat will act as a product (or be on the product side).
Suppose there's an imaginary equation:
A + B -----> C (Now if I lower the amount of B, the equilibrium will shift to left to make up the lost B, or to bring the system back to equilibrium)
Apply the same concept as above below:
A + B -------> C + Heat (as I mentioned, since this is exothermic reaction heat is written as product, so if you lower the temperature, which means basically lower the heat, the reaction will shift towards right to make up the lost heat, in this process you will make extra C which is products. Thus, your reaction makes more products.
Option "A" is the correct answer.
Texas produces more crude oil than any other state in the Union. Texas has 27 petroleum refineries with a total capacity of more than 5.1 million barrels of oil per day. Daily production of refined oil makes up 29% of the united State's refining capacity.
Texas and oil are synonymous. In 2006, the oil industry employed 3.1 percent of the state's workforce and produced $ 30.6 billion in earned income.
The oil drilled in Texas is used for everything from vehicle fuel to heating homes. Most of the oil in Texas is produced through drilling which differs from the tar-sand production of Alaska where the oil is closer to the surface.
Answer: The molarity of an HCl solution is 0.218 M if 43.6 mL of a 0.125 M NaOH solution are needed to titrate a 25.0 mL sample of the acid.
Explanation:
Given: 
= 43.6 mL, 
= 0.125 M
= 25.0 mL, 
= ?
Formula used to calculate the concentration of acid is as follows.
Substitute the values into above formula.
Thus, we can conclude that the molarity of an HCl solution is 0.218 M if 43.6 mL of a 0.125 M NaOH solution are needed to titrate a 25.0 mL sample of the acid.
While metal B is being reduced from an ion to a solid metal, metal A is being oxidized.
Metal A is being displaced because, through oxidation, it transforms from a solid metal to ions in a solution.
What is Oxidation ?
Redox reactions include a change in the oxidation state of the substrate. Loss of electrons or a rise in an element's oxidation state are both considered to be oxidation.
Gaining electrons or lowering the oxidation state of an element or its constituent atoms are both examples of reduction.
In general, the term "reduction" refers to a reaction in which a chemical receives additional electrons; the compound that gets electrons is referred to as being reduced. We can think of the transformation of a ketone or an aldehyde into an alcohol as a two-electron reduction because hydride can be thought of as a proton plus two electrons.
So finally we can say that Metal A is being oxidized.

the complete question in attached figure
Let
x------------------- > actual yield
y------------------- > theoretical yield
z------------------- > percent yield
we have that
z=x/y
we know
x=47 g
y=56 g
therefore
z=47/56=0.839 ---------------- > 83.9%
the answer is the option C 83.9%
