The answer would be :
It is a plant cell because starch is the energy storing molecule in plant cells.
Hope this helps !

Answer:
Fluorine is a <em>non-metal, fills its shell by gaining one electron </em>and<em> becomes a negatively charged ion.</em>
Explanation:
Fluorine have seven electrons in its outermost shell. This means that fluorine is located in Group 17(<em>Halogens</em>) in the Periodic Table. Note that halogens are non-metal elements. So fluorine is a non-metal.
Fluorine fills its shell by gaining one electron because it only needs one electron to achieve stable octet electron arrangement. ( it's easier to gain one electron than to lose all seven electrons in the outermost shell)
As fluorine atom gain one electron to achieve stable octet electron arrangement, its number of electrons becomes greater than its number of protons. So it becomes a negatively charged ion.
Answer:
Initial temperature of the gas cylinder was 167.7K
Explanation:
Based on Gay-Lussac's law, the pressure of a gas under constant volume is directly proportional to its absolute temperature. The equation is:
P1*T2 = P2*T1
<em>Where P is pressure and T absolute temperature of 1, initial state and 2, final state of the gas.</em>
<em />
Replacing:
P1 = 1.25atm
T2 = 354.2K
P2 = 2.64atm
T1 = ?
1.25atm*354.2K = 2.64atm*T1
167.7K = T1
<h3>Initial temperature of the gas cylinder was 167.7K</h3>
As the intermolecular forces get weaker, the amount dissolved decreases. Ammonia can form hydrogen bonds with water thus allowing it to be more soluble. CO2 and O2 can only react through London forces, but since CO2 has a higher molecular mass, more electrons, it will have a larger in magnitude temporary dipole moment. This results in the CO2 being more soluble in water than O2.
The overall trend in solubility is NH3>CO2>O2
Because you need oxygen in your blood stream and it revives cells as it travels through.
