10 cubic inches
We will use Boyle's law that states that for a fixed amount of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional.
P1 V1 = P2 V2
Where
P1 is initial pressure = 5 psi
V1 is initial volume = 20 cubic inch
P2 is final pressure = 10 psi
V2 is final volume = unknown
V2 = P1,V1 / P2
V2 = 20 × 5 / 10
V2 = 100/10
V2 = 10 cubic inches
Answer:
Carbon has the highest mass percent
Explanation:
Step 1: Data given
Predict the element that will have the highest mass percent composition in each compound without doing any calculations.
For C3H6O, carbon will have the highest mass percent. The molar mass of of Oxygen and carbon are more or less the same. But we have 3x more Carbon than oxygen.
Identify the element that has the highest mass percent composition in C3H6O .
atomic mass C = 12.01 g/mol
atomic mass O = 16.0 g/mol
atomic mass H = 1.01 g/mol
molar mass C3H6O = 58.08 g/mol
%C = (3*12.01 / 58.08) * 100 %
%C = 62.04%
%O = (15.99 /58.08) *100%
%O = 27.53 %
%H = (6*1.01 / 58.08) * 100%
%H = 10.43
Carbon has the highest mass percent
Hope this helps. Baking soda and vinegar react chemically because one is a base and the other is an acid. Baking soda is a basic compound called sodium bicarbonate. Vinegar is a diluted solution that contains acetic acid.
basically a explosion
Answer:
Option D is the correct answer
Explanation:
There are three hydrogen bonds formed between Guanine and Cytosine base.
The first hydrogen bond is formed between the oxygen atom on Carbon-6 (C-6) of guanine, and one of the hydrogen atoms attached to the Nitrogen atom (i.e the one of the hydrogen atoms in the amino group) on the Carbon-4 (C-4)of the cytosine base.
The second hydrogen bond is formed between the hydrogen atom on Nitrogen-1 (N-1) of the guanine base and Nitrogen-3 (N-3) of the cytosine base.
The third hydrogen bond exist between one of the hydrogen atoms in the amino group attached to the second Carbon (C-2) of the guanine base, and the oxygen atom attached to the second Carbon (C-2) of the cytosine base.
