Why does food have potential energy?

Chemistry
2 answers:
Sonja [21]3 years ago
6 0

Answer:

that's because food molecules contain potential energy, or stored energy, that can do work in the future. When your body breaks down these molecules, energy is released that it can use to do work, like walk or think.

Answer:

So that if we feel weak, energy is released through it so we can do work and do stuff like walk or think. It's like stored energy that can do things for the future.

Please give brainliest if it helped.

Sulfonation of naphthalene, C10H8, results in two products. One product is kinetically favored and predominates in the beginning
Marrrta [24]

Explanation:

The sulfonation of the naphthalene yield 2 products under different conditions:

<u>When the reaction is carried at 80 °C, 1-naphthalenesulfonic acid is the major product because it is kinetically favoured product as arenium ion formed in the transition state corresponding to 1-naphthalenesulfonic acid is more stable due to better resonance stabilization. </u>

<u>When the reaction is carried at 160 °C, 2-naphthalenesulfonic acid is the major product as it is more stable than 1-naphthalenesulfonic acid because of  steric interaction of the sulfonic acid group in 1-position and the hydrogen in 8-position.</u>

The products are shown in image below.

Which pair of compounds will form a buffer in aqueous solution?
nikdorinn [45]
Buffer solutions consist of an aqueous solution of a weak acid and its conjugate base or a weak base and its conjugate acid. Buffer solutions are used to have better control of the pH of solutions.

An example of a weak acid and its conjugate base is acetic acid (CH3COOH) and sodium acetate (CH3COONa).

How much Ca(NO3)2 should be weighed out to have 0.650 mol?A) 66.4 g.B) 97.68.C) 107 g.D) 133 g.E) 165 g.
Bogdan [553]

Answer:

C) 107 g

Explanation:

Step 1: Calculate the molar mass of Ca(NO₃)₂

We can calculate the molar mass of Ca(NO₃)₂ by adding the masses of its elements.

M = 1 × Ca + 2 × N + 2 × 3 × O

M = 1 × 40.08 g/mol + 2 × 14.01 g/mol + 6 × 16.00 g/mol

M = 164.10 g/mol

Step 2: Calculate the mass corresponding to 0.650 moles of Ca(NO₃)₂

We multiply the number of moles by the molar mass.

0.650 mol × 164.10 g/mol = 107 g
