Answer:
54.616
Explanation:
8.647 + 45.969
or rewrite for easier look:
45.969 +
8.647 =
54.616
Hope this helped :3
Answer:
The first five elements of the periodic table are:- hydrogen, helium, lithium, beryllium, boron
Explanation:
atomic number- it is represented by the letter Z. It is basically the total number of protons present in each atom's nucleus of that element.
atomic mass- is the mass of a single atom present in the element.
electrons and protons- they are negatively and positively charged particles found in the nucleus of the atom respectively.
neutrons- they have no or zero charge and weigh more than protons.
element | atomic number | atomic mass | electrons | protons | neutrons
hydrogen (H)- 1 | 1.008 | 1 | 1 | 0
helium (He) - 2 | 4.0026 | 2 | 2 | 2
Lithium (Li) - 3 | 6.94 | 3 | 3 | 4
beryllium (Be) - 4 | 9.0122 | 4 | 4 | 5
Boron ( B) - 5 | 10.81 | 5 | 5 | 6
Answer:
C
Explanation
I would guess water vapor because it cant really change form from there unless you split it
Answer:
cellular respiration
Explanation:
All exergonic processes produced in the cell, through which substances oxidize and chemical energy is released, are grouped under the name of cellular respiration, but to break down an organic molecule the cells employ, mainly dehydrogenations that can be carried carried out in the presence or absence of atmospheric O2 oxygen. There are therefore two types of breathing: aerobic respiration and anaerobic respiration. The latter also called fermentation.
Aerobic respiration (oxidative phosphorylation)
- Use molecular O2.
- It degrades glucose to CO2 and H2O
- Exergonic
- Recovers about 50% of chemical energy
- Present in most organisms.
- It uses enzymes located in the mitochondria.
<span>Carbon must share 4 electrons total with the the two Oxygen atoms in order to fill it's outer electron shell, and each Oxygen atom must share 2 electrons with the Carbon atom to fill their electron shells. Therefore, in total 8 electrons must be shared (4+2+2=8)</span>
