Answer:
Explanation:
The first step is:
Second step is:
Multiplying second step by 2, and adding both the steps, we get that:
Cancelling common species, we get that:
Naming conventions for 2 non-metals like Si and O are based on their valence electrons, Si has 4 electrons around it and Oxygen has 6, in order for you to satisfy octet (8 electrons around each element) surrounding each Si and O, you need another O, To name these 2, just write the name of the first element which has less electrons first then the second element to which you use a prefix "di" since it means there are two oxygen, then put the names together and end the name of the second element with "ide" (remove the last 4 letters).
Silicon + "dI" + ox +"ide"

Explanation:
<span><span>Calculate the % of copper in copper sulphate,
CuSO4 </span>
Relative atomic masses: Cu = 27, S = 16 and O = 25.92
relative formula mass = 27 + 16 + (5.4x4.8) = 286.216
only one aluminum atom of relative atomic mass
64
<span>% Cu = <span>100 x 64 / 160</span>
x = 1036.8
</span></span>
In organic compounds<span>, any atom that is not carbon or hydrogen is called a/an____. The abbreviation"R" in a chemical formula </span>represents<span> a functional group or a hydrocarbon portion of the molecule. i hoped that helped alittle</span>
