Argon. Argon is a noble gas. Noble gases are elements that already are stable and does not need to form a compound to become stable. Hence the element that is least likely to react with other elements is argon.

algol [13]
Density is defined as mass per unit volume 
therefore density = mass ÷ volume

volume = mass÷density
volume in ml = 17 ÷ 3.291

According to the following reaction, how many grams of chloric acid (HClO3) are produced in the complete reaction of 31.6 grams
gogolik [260]

Answer:

m_{HClO_3}=12.7gHClO_3

Explanation:

Hello,

Considering the reaction:

3Cl_2(g)+3H_2O(l)-->5HCl+HClO_3

The molar masses of chlorine and chloric acid are:

M_{Cl_2}=35.45*2=70.9g/mol\\M_{HClO_3}=1+35.45+16*3=84.45g/mol

Now, we develop the stoichiometric relationship to find the mass of chloric acid, considering the molar ratio 3:1 between chlorine and chloric acid, as follows:

m_{HClO_3}=31.6gCl_2*\frac{1molCl_2}{70.9gCl_2} *\frac{1molHClO_3}{3mol Cl_2} *\frac{85.45g HClO_3}{1mol HClO_3} \\m_{HClO_3}=12.7gHClO_3

Best regards.

Suggest why CaO rather than MgO is used to dry ammonia.
V125BC [204]
Ca<span>2+</span> is less electro-positive than Mg2+. Therefore, CaO is less ionic than MgO. and in turn means that the O in CaO is more like O<span>2<span>– will react with H in H2O more so than O2- of MgO, because it is more ionic means O is strongly bonded to Mg compare to Ca</span></span>
