Answer : The correct option is B: The acid donates an H + ion.

Explanation :

According to Bronsted -Lowry theory, an acid is a substance that donates a proton. The substance that is left after the proton is donated is known as "conjugate base" of that acid.

Consider a general acid HA. The dissociation reaction of the acid can be written as follows.

$HA (aq) + H_{2}O (l)\rightleftharpoons H_{3}O^{+} (aq)+ A^{-}(aq)$

In the above example, HA behaves as an acid because it donates proton to H₂O. When the proton is donated, A⁻is formed on the product side which is a conjugate base of HA.

From above discussion, we can say that a substance and its conjugate differ by a proton, H⁺ only.

Therefore the acid donates an H + ion is the correct option.

Can show some work for 4x = -12

timama [110]

4x = -12

First, divide both sides by 4. / Your problem should look like: $x = -\frac{12}{4}$
Second, since 4 goes into 3 to get 12, simplify it by 3. / Your problem should look like: $x = -3$

Answer: x = -3

Describe the oxygen/carbon dioxide cycle using plants and animals.

Vikentia [17]

Answer:

The process of photosynthesis in plants releases oxygen into the atmosphere. Respiration by plants and animals, as they use the energy stored in food, and the process of decomposition of dead organisms, releases carbon dioxide into the atmosphere. All three work together to maintain the carbon dioxide-oxygen cycle.

If body fats has a density of 0.94 g/mL and 3.0 liters of fat are removed, how many pounds of fat were removed from the patient?

-Dominant- [34]

Answer:

6.217 pounds

Explanation:

We are given;

Density of body fats 0.94 g/mL
Volume of fats removed = 3.0 L

We are required to determine the mass of fats removed in pounds.

We need to know that;

Density = Mass ÷ volume

1 L = 1000 mL, thus, volume is 3000 mL

Rearranging the formula;

Mass = Density × Volume

= 0.94 g/mL × 3000 mL

= 2,820 g

but, 1 pound = 453.592 g

Therefore;

Mass = 2,820 g ÷ 453.592 g per pound

= 6.217 pounds

Thus, the amount of fats removed is 6.217 pounds
