How can I calculate the mass percent of carbon, nitrogen and oxygen in acetamide, C2H5NO?

Chemistry
1 answer:
Arte-miy333 [17]3 years ago
6 0

Partial mass of C, 12*2 = 24

Partial mass of H, 1*5 = 5

Partial mass of N, 14

Partial mass of O, 16

Now, total molar mass would be 24+5+14+16 = 59

mass % of carbon = 24 * 100 / 59 = 40.67%

If density usually increases with decreasing temperature, why does ice float on liquid water? Explain.
zepelin [54]

Answer:

If you continue to cool water past 4 degrees Celsius, its density starts to plummet (you can see this in the graph). At zero degrees, i.e., the temperature at which water turns into ice, the density of water is actually quite low. It turns out that ice has a lower density than water, and any object that has a lower density than the liquid form on which it’s kept (in this case, water) will be able to float!

What was done to the linear parent function, f(x) = x, to get the function<br>g(x) = 1/6 x​
s2008m [1.1K]

Answer:

Vertically Shrunk by a factor of 1/6

Explanation:

Parent Formula: f(x) = a(bx - c) + d

<em>a</em> - vertical shrink/stretch and x-reflections

<em>b</em> - horizontal shrink/stretch and y-reflections

<em>c</em> - horizontal movement left/right

<em>d</em> - vertical movement up/down

Since we are only modifying <em>a</em>, we are dealing with vertical shrink/stretch:

Since a < 1 (1/6 < 1), we are dealing with a vertical shrink of 1/6.

Since a > 0 (1/6 > 0), we do not have a reflection over the x-axis.

If acids are compounds that release protons (h+), how is it that sox and nox cause acid rain?
tino4ka555 [31]
The protons come from water. Sulfur oxides dissolve in water to form sulfurous and sulfuric acids, and nitrogen oxides dissolve to form nitrous and nitric acids.

Which pathway is correct? proteins to RNA to DNA, DNA to RNA to proteins , RNA to DNA to proteins or DNA to proteins to RNA
Annette [7]

Answer:

The sequence order should be DNA to RNA to Proteins.

Explanation:

For you to get the RNA sequence, you need to find a match for the DNA sequence. Your RNA sequence should only have either AUCG for your 4 nucleotide bases. Once you have the RNA sequence found by pairing it with the DNA sequence, you would then to do use an RNA codon chart to find the amino acids. These amino acids are basically your proteins.

What is a chemical change?
PIT_PIT [208]
A chemical change is a change that results in new chemicals (the reactants underwent a chemical change which resulted in new products). 
an example of a chemical change is the burning of paper. An example of something that is not a chemical change is the melting of ice.
