The chemical formula of the solute is NaNO3. The mass of this is 1.4*85=119 g. The boiling point of the solution is higher than water. The molarity of this solution is 1.4/2=0.7 M.
Yes. You can either treat the entire polyatomic ion as a unit or separate the elements in the polyatomic ion. Pay attention the parentheses and subscripts, though. Those can confuse people a lot. I personally find it easier to just treat it as a whole unit.
The reaction equation is:
Li + Br → LiBr
39 grams of Li = 39 / 7 = 5.57 moles of lithium
41.5 grams of Br = 41.5 / 80 = 0.52 mole of bromine
Answer:
CaO
how:
since its an iconic compound (metal(Ca)+non-metal(O)=iconic(CaO) we have to take account the charges
so;
now we will cross them
since both the values are same will cross it out.
hence: CaO
<span>To solve this question, you need to find the equation of the reaction. I assume that the equation look like this:
2NaBr+F2</span>→<span>2NaF+<span>Br<span>2
In the equation, you can see that every 1 F2 molecule there used there will be 2 NaF(sodium fluoride) formed. So, the number of </span></span></span>sodium fluoride produced would be: <span>0.480 mol * 2= 0.96 moles</span>
