Answer:
<u><em>Bullys.</em></u>
Explanation:
<h3>{: I took the quiz in K12 and the first time I put <u><em>Pencils</em></u> but it said it was wrong and the right one is <em>Bullys. I hope this helps! :]</em></h3>
The same amount of energy is released when they recombine.
<h3>How to separate oxygen and hydrogen from water?</h3>
- Electrolysis is a promising choice for without carbon hydrogen creation from inexhaustible and atomic assets.
- Electrolysis is the method involved with utilizing power to part water into hydrogen and oxygen.
- This response happens in a unit called an electrolyzer.
- Electrolyzers can go in size from little, apparatus size hardware that is appropriate for limited scope dispersed hydrogen creation to huge scope, focal creation offices that could be tied straightforwardly to sustainable or other non-ozone depleting substance radiating types of power creation.
<h3>How Does it Work?</h3>
Like energy components, electrolyzers comprise of an anode and a cathode isolated by an electrolyte. Different electrolyzers capability in various ways, fundamentally because of the different kind of electrolyte material included and the ionic species it conducts.

Answer:
0.069moles
45.65%
Explanation:
Firstly, we need to calculate the number of moles of CO2 produced. We can use the ideal gas equation for this.
PV = nRT
n = PV/RT
according to the question,
P = 746torr
V = 1.73L
T = 26 = 26 + 273.15 = 299.15K
n = ?
R = 62.364 L. Torr/k.mol
n = (746 * 1.73)/(62.364 * 299.15) = 0.069moles
B. To get this, we can use their molar masses. The molar mass of calcium carbonate is 100g/mol while for magnesium carbonate, molar mass is 84g/mol
The percentage by mass is (84)/(84 + 100) * 6.53g = 2.98g
= 2.98/6.53 * 100 = 45.65%
The most stable conformation of 3-isopropyl-1,1dimethylcyclohexane equatorial ethyl group (more stable). The stability of ethylcyclohexane's equatorial conformer exceeds that of its axial conformer by 7.4 kJ/mol.
According to the previous section, the chair conformation with the equatorial methyl group is more stable because it reduces steric repulsion, and as a result, the equilibrium favors the more stable conformer. Strongly favoring the equatorial shape is methylcyclohexane. The methyl group is in close proximity to the axial hydrogens in the axial conformation, which has an energetically unfavorable effect known as a 1,3-diaxial interaction. The methyl group prefers the equatorial shape as a result. The conformation of ethylcyclohexane in which the ethyl group is in the equatorial position is the most stable.

Answer:
I would say that it is the bond called complementary hydrogen bonds
Explanation:
The nucleotides in a base pair are complementary which means their shape allows them to bond together with hydrogen bonds. The A-T pair forms two hydrogen bonds. The C-G pair forms three. The hydrogen bonding between complementary bases holds the two strands of DNA together.
