<h3>What are decomposition reactions?</h3>

Decomposition reactions are type of reactions in which a compound is broken down into two or more products.

When a soluble substance or a compound is dissolved in water it forms an aqueous solution.
When this happens the soluble compound such as ionic compounds ionizes to form ions.
This is an example of decomposition reaction, since the ionic compound decomposes it ions making it.
For example, sodium sulfide is an ionic compound that ionizes in water to form sodium and sulfide ions.

That is;

Na₂S(s) → 2Na⁺(aq) + S²⁻(aq)

Mature elephants consume an average of 600 pounds of food per day. If an elephant

MAXImum [283]

Answer:

$\large \boxed{\text{4 600 000 kg or 4600 Mg}}$

Explanation:

1. Calculate the adult life

If the elephant is an adult from its 10th birthday until the day before its 56th birthday, its

Adult life = 55 - 10 + 1 = 46 yr

2. Convert years to days

$\text{Adult life} = \text{46 yr} \times \dfrac{\text{365.25 da}}{\text{1 yr}} = \text{16 800 da}$

3. Convert days to pounds of feed

$\text{Feed} = \text{16 800 da} \times \dfrac{\text{600 lb}}{\text{1 da}} = 1.01 \times 10^{7} \text{ lb}$

4. Convert pounds to kilograms and megagrams

$\text{Feed} =1.01 \times 10^{7} \text{ lb} \times \dfrac{\text{1 kg}}{\text{2.20 lb}} =\textbf{4 600 000 kg} = \textbf{4600 Mg}\\\\\text{The elephant will eat $\large \boxed{\textbf{4 600 000 kg or 4600 Mg}}$ of food.}$

Note: The answer can have only two significant figures because that is all you gave for age of the elephant.
