Answer:
2 grams.
Explanation:
H2 + O2 ---> H2O2
Using molar masses:
2*1 g hydrogen reacts with 2*16 g oxygen.
so 2g H2 reacts with 32 g O2.
- Energy transformation includes ATP and ADP. at the point when energy is delivered, the response will in general separate a bigger particle to a more modest structure.
- For this situation, the bigger particle is ATP comprised of three phosphates bunches while ADP is just made out of two phosphate gatherings.
<h3>What is the energy source for the conversion of
ADP and ATP?</h3>
- The energy expected for the change of ADP into ATP is acquired from light during photosynthesis and from exothermic responses during cell breath in the two plants and creatures.
- ADP is produced on hydrolysis of ATP and the energy released in the process is utilised to carry out various cellular processes.

Answer:
37.1°C.
Explanation:
- Firstly, we need to calculate the amount of heat (Q) released through this reaction:
<em>∵ ΔHsoln = Q/n</em>
no. of moles (n) of NaOH = mass/molar mass = (2.5 g)/(40 g/mol) = 0.0625 mol.
<em>The negative sign of ΔHsoln indicates that the reaction is exothermic.</em>
∴ Q = (n)(ΔHsoln) = (0.0625 mol)(44.51 kJ/mol) = 2.78 kJ.
Q = m.c.ΔT,
where, Q is the amount of heat released to water (Q = 2781.87 J).
m is the mass of water (m = 55.0 g, suppose density of water = 1.0 g/mL).
c is the specific heat capacity of water (c = 4.18 J/g.°C).
ΔT is the difference in T (ΔT = final temperature - initial temperature = final temperature - 25°C).
∴ (2781.87 J) = (55.0 g)(4.18 J/g.°C)(final temperature - 25°C)
∴ (final temperature - 25°C) = (2781.87 J)/(55.0 g)(4.18 J/g.°C) = 12.1.
<em>∴ final temperature = 25°C + 12.1 = 37.1°C.</em>
Hydrogen ion, strictly, the nucleus of a hydrogen atom separated from its accompanying electron. The hydrogen nucleus is made up of a particle carrying a unit positive electric charge, called a proton. The isolated hydrogen ion, represented by the symbol H+, is therefore customarily used to represent a proton.
