Answer:
2 HCl + CaCO3 = CaCl2 + H2O + CO2
Explanation:
On the right side we have 2xCl, to get the same amount we will multiply HCl on the left side by 2.
This will give us 2xH on the left side; we also have 2xH on the right side ( in H2O).
On both sides we have 1x Ca; 1x C.
On the left side we have 3XO (in CaCO3), on the right side we have 1O in H20 and 2xO in CO2, so 3x O on the right side as well.
The reaction is balanced.
The input for cellular response is O2
Answer: The two substances are the same because their intensive property is the same.
Explanation: the answer is The two substances are the same because their intensive property is the same.
this is the correct answer because the boiling point is a is a bulk property this mean that is a property of substance or sample which does not change as the amount of substance or sample changes.
also we have to keep in mind that the boiling point is is a physical property that is not dependent on the size or mass of a sample.
so we can conclude that you can change the mass, the volume of this sample or this substance the boiling point always will be the same.

Answer:
Bond is expected to be sold at the face value .
Explanation
In cases where market interest rate of bond is lower than coupon rate of bond, the bond is issued at a premium. Reason being that company is giving higher interest rate on bond , this higher rate of interest increases the price of bond, thus, bond is issued at premium.
In a scenario where market interest rate of bond is higher than coupon rate of bond, the bond is issued at Discount. This is so in that company is not returning more than market rate, therefore, to compensate that, the sale value of bond is usually lower than face value.
If the Market rate and coupon rate is equal , then bond will be issued at face value.
Considering the given question, Coupon rate of bond is 6% and market rate is also 6%. In this question , Market yield is considered to be market rate .
Therefore, there is no need to calculate present value of interest payments and redemption value at maturity to calculate price of bond.
