0.500 moles is roughly .5*6.022*10^23=3.011*10^23 atoms. This is independent of STP.
Just find the percent mass of oxygen in sucrose again. and then multiply that by 50.00.
In order to find the answer, use an ICE chart:
Ca(IO3)2...Ca2+......IO3-
<span>some.......0..........0 </span>
<span>less.......+x......+2x </span>
<span>less........x.........2x
</span>
<span>Ca(IO₃)₂ ⇄ Ca⁺² + 2 IO⁻³
</span>
K sp = [Ca⁺²][IO₃⁻]²
K sp = (x) (2 x)² = 4 x³
7.1 x 10⁻⁷ = 4 x³
<span>x = molar solubility = 5.6 x 10</span>⁻³ M
The answer is 5.6 x 10 ^ 3 M. (molar solubility)
Answer:
Reactants are transformed into products
Explanation:
Chemical reactions are happening everywhere, it may be represented by the following equation:
A(aq) + B(s) ⇒ C(g) + D(l)
The left side represent the reactants that interact to get the products.
In the parenthetycal note is the state of the compound, in this case, aquose solution (aq), solid (s), gas (g), liquid (l)
