Determine the percent water in MgSO4*7H20?
Semmy [17]

Answer:

\% H_2O=51.2\%

Explanation:

Hello!

In this case, since the percent water is computed by dividing the amount of water by the total mass of the hydrate; we infer we first need the molar mass of water and that of the hydrate as shown below:

MM_{MgSO_4* 7H_2O}=120.36 g/mol+7*18.02g/mol\\\\MM_{MgSO_4* 7H_2O}=246.5g/mol

Thus, the percent water is:

\% H_2O=\frac{7*MM_{H_2O}}{MM_{MgSO_4* 7H_2O}} *100\%\\\\

So we plug in to obtain:

\% H_2O=\frac{7*18.02}{246.5} *100\%\\\\\% H_2O=51.2\%

Best regards!

Rosa drew a flow chart of the carbon cycle.
Lisa [10]

The correct Answer is A.

The Flow chart of the Carbon Cycle, will look as follows:

1. Carbon dioxide in the atmosphere.

2. Producers undergo photosynthesis (in this process plants among other producers like algae, use CO2 to produce energy).

3. Consumers eat producers (a primary level of consumer like a rabbit eats the producers or plants).

4. Decomposers return Carbon to the soil and release waste.

And the  cycle continues again, by going back to step 1.
