Volgvan3 years ago

Answer:

When two forces acting on an object are of similar size but acting in opposite directions, we say they are forces of balance. If the forces on an object are balanced (or if there are no forces acting on it), this is what happens: the object stays stationary

Write a net ionic equation to show that benzoic acid, C6H5COOH, behaves as a Brønsted-Lowry acid in water.
Nitella [24]

Answer:

H⁺(aq) + H₂O(l) ⇄ H₃O⁺(aq)

Explanation:

According to Brönsted-Lowry acid-base theory, an acid is a substance that donates H⁺. Let's consider the molecular equation showing that benzoic acid is a Brönsted-Lowry acid.

C₆H₅COOH(aq) + H₂O(l) ⇄ C₆H₅COO⁻(aq) + H₃O⁺(aq)

The complete ionic equation includes all the ions and molecular species.

C₆H₅COO⁻(aq) + H⁺(aq) + H₂O(l) ⇄ C₆H₅COO⁻(aq) + H₃O⁺(aq)

The net ionic equation includes only the ions that participate in the reaction and the molecular species.

H⁺(aq) + H₂O(l) ⇄ H₃O⁺(aq)

A sleeping 68 kg man has a metabolic power of 65 w . you may want to review ( pages 323 - 327) . part a how many calories does h
Kazeer [188]

<u>Given:</u>

Mass = 68 kg

Power = 65 W

<u>To determine:</u>

Calories burned during an 8.0 hr sleep

<u>Explanation:</u>

Energy is expressed as:

Energy = Power * Time

Now, the unit of power = Watt (W)

1 W = 1 J/s i.e. 65 W = 65 J/s

Time = 8 hrs = 8 * 3600 s = 28800 s

Energy = 65 J/s * 28800 s = 1872000 J

Convert Joules (J) to calories (cal)

1 cal = 4.184 J

The calculated energy = 187200 J * 1 cal/4.184 = 447418 cal

Ans: The man burns nearly 447.4 kcal during an 8 hr sleep

The reaction between iodine and carbon dioxide to yield diiodine pentoxide is exothermic. How could the yield of diiodine pentox
Romashka [77]

Answer:

Increasing the temperature

Explanation:

According to Le Chatelier's principle, "if any of the conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".

Since the forward reaction is exothermic, this suggests that heat is given off in the reaction.

Increasing the temperature will favors the reverse process which is endothermic.

In going from the reactants to the the products, the reaction is deemed exothermic which suggests that it produces heat.

The backward reaction is endothermic i.e it absorbs heat. If the temperature is increased, this process will be favored and more reactants produced. Less of the diiodine pentoxide will form. There is a leftward shift of the equilibrium

Which substance is most likely to heat up the fastest?
Vladimir [108]
Specific heat is measuring how much heat is needed to raise one gram of a substance by one degree Celsius. Therefore, the substance with the lowest specific heat requires the least amount of energy to raise its temperature. This means if all of the substances got the same amount of heat, the substance with the lowest specific heat's temperature would raise the most. Or, if each substance was exposed to constant heat, the substance with the lowest specific heat would heat up the fastest. Since copper has the lowest specific heat, the answer is copper.
