Answer:
negative
Explanation:
When something slows down, its acceleration is the opposite of the velocity.
<span>By convention maternal alleles are represented in first row and paternal alleles in first column (leaving the first square empty), thus each square shows the genotype of the progeny formed as the result of cross between corresponding alleles</span>
3. Plasma
- indefinite shape & volume
- affected by magnetic and electric field
- drift and flow freely
4. Liquids have fixed volume meaning packed tighter together as gases do not have fixed shape or volume .
D would be correct
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
