Answer:

Step 1. Asking a research question

Step 2. Do background research

Step 3. Propose a hypothesis

Step 4. Perform Controlled experiment  

Step 5. Collection of data

Step 6. Analysis of data

Step 7. Conclusion

Explanation:

A scientific method is a systematic approach to understand and explain the natural phenomenon.

The method includes the steps which should be followed in the sequence which begins with making an observation thorough senses, asking questions which could be answered, doing background research and proposing a well-educated guess called hypothesis which could be tested.

Then the experiment is performed to test the hypothesis which provides results which could be collected and analysed. Conclusions, are drawn from the results and must be communicated to the scientific community for verification.

Calculate the mass of magnesium carbonate ( MgCO3), in grams, required to produce 110.0 g of carbon dioxide using the following
bearhunter [10]

Answer:

210.7~g~MgCO_3

Explanation:

We have to start with the <u>reaction</u>:

MgCO_3~->~MgO~+~CO_2

We have the same amount of atoms on both sides, so, we can continue. The next step is to find the <u>number of moles</u> that we have in the 110.0 g of carbon dioxide, to this, we have to know the <u>atomic mass of each atom</u>:

C: 12 g/mol

O: 16 g/mol

Mg: 23.3 g/mol

If we take into account the number of atoms in the formula, we can calculate the <u>molar mass</u> of carbon dioxide:

(12*1)+(16*2)=44~g/mol

In other words: 1~mol~CO_2=~44~g~CO_2. With this in mind, we can calculate the moles:

110~g~CO_2\frac{1~mol~CO_2}{44~g~CO_2}=25~mol~CO_2

Now, the <u>molar ratio</u> between carbon dioxide and magnesium carbonate is 1:1, so:

2.5~mol~CO_2=2.5~mol~MgCO_3

With the molar mass of MgCO_3 ((23.3*1)+(12*1)+(16*3)=84.3~g/mol. With this in mind, we can calculate the <u>grams of magnesium carbonate</u>:

2.5~mol~MgCO_3\frac{84.3~g~MgCO_3}{1~mol~MgCO_3}=210.7~g~MgCO_3

I hope it helps!
