1 - In what organelle or membrane are triacylglycerols synthesized and fatty acids elongated?
A - Lysosomes
B - Peroxisome
C - Endoplasmic reticulum
D - Ribosomes
E - Nucleus
The answer is Endoplasmic reticulum
They each have one valence electron in their outer shell, but they are also on the same row (period). If you follow this pattern, potassium will also have one valence electron.
Hope this helps!! :)
Answer:
Opion 4. The hydrogen in HCl reduce from proton to hydrogen gas (H at ground state)
Explanation:
The reaction is: Mn + HCl → MnCl₂ + H₂
Magnessium changed the oxidation state from 0 to +2
It has increased, so it was oxidized
H changed the oxidation state from +1 to 0
It has decreased, so it was reducted.
Answer:
27.2 a.m.u
Explanation:
Isotope of an element is its tendency to exist in two or more forms. Thus, the average atomic mass of the element is required. And this can be calculated by adding the individual product of the percentage isotope and its mass.
The average atomic mass of the element can be determined by:
= (70% x 26) + (30% x 30)
= (0.7 x 26) + (0.3 x 30)
= 18.2 + 9
= 27.2
Thus, the average atomic mass of element X is 27.2 a.m.u
