A) Burning
Burning is a chemical reaction while the other three answers are physical reactions.
The two atoms shown in the equation are CALCIUM and oxygen.
<span>You start off with a neutral calcium atom with a shell of two electrons, a shell of 8 around that, a shell of 8 around that, and a shell containing 2...with no charge. </span>
<span>20 protons + 20 electrons. </span>
<span>You also have an oxygen atom with a shell of 2, and a shell of 6...with no charge. </span>
<span>8 protons + 8 electrons. </span>
<span>Each ionizes to form a calcium ion with 2 electrons removed (from the outer shell), leaving a +2 charge (20 protons, 18 electrons)... </span>
<span>and an oxygen ion with 2 electrons added (to the outer shell), leaving a -2 charge (8 protons, 10 electrons). </span>
<span>Their electrostatic attraction causes them to come together to form an ionic compound of CaO in a crystal lattice.</span>
Answer:i think it is c, it explodes in water because that’s a chemical reaction
Explanation:
Answer:
2 ATP
Explanation:
glycolysis is the beginning of cellular respiration and it yielded net ATP of two produced from 1,3 bisphosphoglycerate conversion to 3-phosphoglycerate (2 ATP) and conversion of phosphoenolpyruvate to pyruvate ( 2ATP). One will recall that 2 ATP had been expended in the conversion of glucose to glucose-6-phosphate, and in the conversion of fructose-6-phosphate to fructose -1,6- bisphosphate. Other product of glycolysis are 2 NADH, 2 Pyruvate that may go into kreb cycle for further energy production depending on the organism type of respiration.
