If a bond is currently trading at its face​ (par) value, then it must be the case​ that: A. the​ bond's yield to maturity is equ
Natasha2012 [34]

Answer:

A. the​ bond's yield to maturity is equal to its coupon rate.

Explanation:

The coupon rate is that amount of bond measured on the loan amount whereas the maturity yield is the rate held up to the settlement date and the investment arise up to the maturity date.

Since the bond is currently trading at its face value that means the bond price is equal to the face or par value

So, the appropriate option is A.

PLEASE HELP ME
pishuonlain [190]

Answer:

Explanation:

Li(s)+1/2 F₂(g)→LiF(s)

In this reaction one mole of product is formed from gaseous state of reactants . So this reaction will represent the reaction for which ΔH∘rxn equals to ΔH∘f .

In other reaction one mole is not produced if we balance the reaction. The reactant must be in gaseous state .  ΔH∘f . represents heat of formation .  ΔH∘rxn represents heat of reaction .

John finds a rock that contains large, light-colored mineral crystals. the rock shows no sign of being altered by heat or pressu
cupoosta [38]

From the above statement, John can infer that the rock underwent metamorphism and also is not altered by heat or pressure.

<u>Explanation</u>:

  • Metamorphic rock is an igneous sedimentary rock and although when put through heat the rock becomes hot but does not alter its shape or melt. If the rock melts then it is only an igneous rock and not a sedimentary one.
  • During metamorphism, the chemical and the mineral content of prolith are changed due to changes in the environment based on physical and chemical conditions.
  • Even though the rocks remain solid, fluid is present between the macroscopic spaces.
  • This gives "The Geologist" accurate information of what happens beneath the earth during the formation of mountains.
  • Metamorphic rocks are like probes that go down the earth and comes back giving information of what happens underneath the surface.

In 1901, Thomas Edison invented the nickel-iron battery. The following reaction takes place in the battery. Fe(s) + 2 NiO(OH)(s)
lord [1]

Ans: Moles of Fe(OH)2 produced is 5.35 moles.


Given reaction:

Fe(s) + 2NiO(OH) (s) + 2H2O(l) → Fe(OH)2(s) + 2Ni(OH)2(aq)

Based on the reaction stoichiometry:

1 mole of Fe reacts with 2 moles of NiO(OH) to produce 1 mole of Fe(OH)2

It is given that there are:

5.35 moles of Fe

7.65 moles of NiO(OH)

Here the limiting reagent is Fe

Therefore, number of moles of Fe(OH)2 produced is 5.35 moles.
