Answer:

The nitrogen fixing bacteria are present in the soil and in the root of the plant in the form of microorganism. It changes the gases of the nitrogen from atmosphere into the component of the solid nitrogen which the plants uses in the soil.

The bacteria coverts the free nitrogen into the form of nitrogen compounds and it decomposes nitrogen compounds into the free nitrogen.

Expressed to the correct number of significant figures, what is the correct sum of (3.04g + 4.134g + 6.1g)?
Lera25 [3.4K]

Answer:

13.3g

Explanation:

3.04g + 4.134g + 6.1g = 13.274g

=13.3g

When expressing the correct number of significant figures in addition, you go to the last common decimal place. In this case that is 0.1 because all the numbers have this decimal place.

This is because your measurement can only be as precise as the least precise measurement. The more decimal places in the measurement, the more precise the measurement.

Be sure to answer all parts. find the most acidic hydrogen in tert−butyl methyl ketone and write a chemical equation for the pro
sleet_krkn [62]
Those Hydrogen atoms which are present at alpha position to carbonyl group are mildly acidic in nature. When such acidic proton containing carbonyl compounds are treated with strong base, they yield enolates. The negative charge created on alpha carbon resonates and shifts to carbonyl oxygen resulting in formation of carbon double bond carbon.

In <span>tert−butyl methyl ketone there are two carbons at each alpha position. Among these two carbons only methyl carbon contains hydrogen atoms while the second one is bonded to further three carbons making it Quaternary carbon. The base abstracts proton from methyl group and enolate is formed. 

</span>tert−butyl methyl ketone in this case acts as acid, Hydroxyl ion acts as base, while the enolate generated is the conjugate base of <span>tert−butyl methyl ketone and Water produced is the conjugate acid of hydroxide ion.</span>

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.
