Answer:
CH2O
Explanation:
Firstly, we need to convert the masses of the elements to percentage compositions. This can be done by placing the mass of each element over the total mass multiplied by 100% . We can start with carbon.
C = 5.692/14.229 * 100 = 40%
O = 7.582/14.229 * 100 = 53.29%
H = 0.955/14.229 * 100 = 6.71%
We then proceed to divide each percentage composition by their atomic mass of 12, 16 and 1 respectively.
C = 40/12 = 3.333
O = 53.29/16 = 3.33
H = 6.71/2 = 6.71
Dividing by the smaller value which is 3.33
C = 3.33/3.33 = 1
O = 3.33/3.33= 1
H = 6.71/3.33 = 2
The empirical formula of the compound ribose is CH2O
Answer:
I think finding the source of the fire would be the most difficult aspect seeing as though the fire would have burned any evidence
Explanation:
Answer is all of the above. Solids have definite shapes, volumes, and mass. Liquids don't have a fixed shape, but have a fixed volume. Gases have neither a fixed shape, volume, or mass
Answer:
triangular prism
Explanation:
triangular prism scatters light through it into 7 spectrum colours , I'm not sure it's the right answer please make sure of it from someone else
The mass number goes on top, and the atomic number goes on bottom.
Therefore, the answer is C:
40
K
19
