Is that a question? Doesnt seem like it
Sulfur is best to bind with oxygen. A covalent bond is a bond between two nonmetal elements. Aluminum is a metalloid and sodium is a metal. Both can't be bonded with sulfur. Neon isn't a metal but is a group 18 element, it's a noble gas. And a noble gas cannot be combined with any element because it already achieved a total of 8 valence electrons. Oxygen on the other hand can be bonded with sulfur since both are non metals
what grade is this because apparently i like to know what grade it is before i solve it
Explanation:
HCL you can do it yourself .try again
The equilibrium expression shows the ratio between
products and reactants. This expression is equal to the concentration of the
products raised to its coefficient divided by the concentration of the
reactants raised to its coefficient. The correct equilibrium expression for the
given reaction is:<span>
<span>H2CO3(aq) + H2O(l) = H3O+(aq) + HCO3-1(aq)
Kc = [HCO3-1] [H3O+] / [H2O] [H2CO3]</span></span>
