Answer:
13mL
Explanation:
Step 1:
The balanced equation for the reaction. This is given below:
HNO3 + KOH —> KNO3 + H2O
From the balanced equation above, we obtained the following data:
Mole ratio of the acid (nA) = 1
Mole ratio of the base (nB) = 1
Step 2:
Data obtained from the question.
This includes the following:
Molarity of the acid (Ma) = 6M
Volume of the acid (Va) =?
Volume of the base (Vb) = 39mL
Molarity of the base (Mb) = 2M
Step 3:
Determination of the volume of the acid.
Using the equation:
MaVa/MbVb = nA/nB, the volume of the acid can be obtained as follow:
MaVa/MbVb = nA/nB
6 x Va / 2 x 39 = 1/1
Cross multiply to express in linear form
6 x Va = 2 x 39
Divide both side by 6
Va = (2 x 39)/6
Va = 13mL
Therefore, the volume of the acid (HNO3) needed for the reaction is 13mL
5480milligrams=5.47×10^1grams
5480×10^-2
5.480×10^(-2+3)
5.48×10^1grams
H 3 0 + is hydronium ion. OH- is hydroxide ion. H+ is hydrogen ion
c group A is the correct answer
After completion of the citric acid cycle, most of the usable energy from the original glucose molecule is in the form of B. ATP
The most basic kind of sugar, monosaccharides only have one kind of sugar molecule. The simplest sugar is glucose, which is also your body's primary energy source. In tests to determine blood sugar levels, sugar is measured. Fructose and galactose, two more monosaccharides, are converted into glucose via metabolism ( 1 , 2 ). For instance, ATP is necessary for both breathing and keeping your heart beating. As well as assisting in the synthesis of lipids and nerve impulses, ATP also facilitates the entry and exit of certain molecules from cells. Even some living things, including bioluminescent creatures like jellyfish and fireflies, use ATP to create light!
