Answer:
We would see 5 peaks. 35Cl the lightest and 37Cl2 the heaviest
Explanation:
The chlorine element has two isotopes (35 Cl and 37 Cl), in the mass spectrum we can observe the m/e of the diatomic molecules. Formed by an atom of chlorine 35 and another of chlorine 35. Or one of Cl 35 and one of Cl 37. Or both of Cl 37.
We can also observe the mass of each separately. That is why we would see 5 peaks.
- Cl = 35 <------------------------- lightest
- Cl = 37
- Cl2 = 35 + 35 = 70
- Cl2 = 35 + 37 = 72
- Cl2 = 37 + 37 = 74 <-------- heaviest
It's b. hydrogen bonds between water molecules
Answer:
The number of mole is 0.04167mole
Explanation:
To convert gram to mole, we need to calculate the molecular weight of the compound
C6H12O6
C - 12
H - 1
O - 16
Molecular weight = 6 * 12 + 1 *12 + 6 * 16
= 72 + 12 + 96
= 180g/mol
To covert gram to mole
Therefore,
= 7.50g/ 180g/mol
= 0.04167 mole of glucose
Answer:
Hydrolysis
Explanation:
The phosphate groups in an ATP molecule are joined forming an ester group. Esters can be formed when an alcohol (-OH) bonds with an acid (-COOH, or, in the case of phosphoric acid, ). When this bonding occurs, the two molecules together lose a molecule of water, because the alcohol loses the hydroxyl and the acid loses an hydrogen, and the three atoms combine to form water. All the chemical bonds that are formed with the loss of a water molecule can also be broken using water, and this reaction is called hydrolysis.
Answer:
3.2 cm X 2.8 cm X 2.6 cm/ 1 cube - not exact
1 mL - exact
1 cm³ - exact
12 cubes/ 1 tray - exact
268.8 mL/tray - not exact
Explanation:
We can use the picture attached below to solve this problem. The first part is not exact because Sally is using a ruler to measure the cube which would have a margin of error, regardless of how small. The is exact, since that is the actual accurate exchange. Next, since there are 12 cubes in a single ice tray this measurement is also exact. Lastly, since Sally's initial measurement of the cubes is not exact, then the final calculated value will also not be exact.
