Answer:
0.48 moles
Explanation:
The bromide has a molarity of 2.6M.
This simply means that in 1dm^3 or 1000cm^3 of the solution, there are 2.6 moles.
Now, we need to get the number of moles in 185ml of the bromide. It is important to note that the measurement ml is the same as cm^3.
We calculate the number of moles as follows.
If 2.6mol is present in 1000ml
x mol will be present in 185 ml.
To calculate x = (185 * 2.6) ÷ 1000
= 0.481 moles = 0.48 moles to 2 s.f
Answer:
(A) An investor will exercise the option to put the bond if yields rise significantly
Explanation:
A put option on the bond is a mechanism to allow the buyer of the bond the ability to compel the lender to repay the principal on the bond. The put option offers the buyer of the bond the ability to collect the principal of the bond anytime they choose until maturity for any purpose.
Recall that once the price drops (that is, the yield increases), put options are exercised. If the yield significantly increased, the put choice on a municipal bond is executed.
The condition that will increase the entropy in a reaction is heating up the reaction (option B).
<h3>What is entropy?</h3>
Entropy in chemistry is the measure or degree of the disorder or randomness present in a chemical system.
In a chemical reaction, reacting substances called reactants collide with one another to form products.
However, the degree at which the reactants collide with one another is referred to as the entropy of the reaction.
Therefore, the condition that will increase the entropy in a reaction is heating up the reaction i.e. increase in temperature.
