For each of the following unbalanced equations,
calculate how many moles of the second reactant
would be required to react completely with
exactly 25.0 g of the first reactant. Indicate
clearly the mole ratio used for each conversion.
a. Mg(s) + CuCl2(aq) → MgCl2(aq) + Cu(s)
b. AgNO3(aq) + NiCl2(aq) →
AgCl(s) + Ni(NO3)2(aq)
C. NaHSO3(aq) + NaOH(aq) →
Na2SO3(aq) + H2O(l)
d. KHCO3(aq) + HCl(aq) →
KCl(aq) + H2O(l) + CO (g)

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

the term hydride is commonly named after binary compounds that hydrogen forms with other elements of the periodic table. hydride compounds in general form with almost any element, except a few noble gases. the trends and properties vary according to the type of intermolecular force that bonds the elements together, the temperature, its molecular masses, and other components. hydrides are classified into three major groups, depending on what elements the hydrogen bonds to. the three major groups are covalent, ionic, and metallic hydrides. formally, hydride is known as the negative ion of a hydrogen, h-, also called a hydride ion. because of this negative charge, hydrides have reducing, or basic properties. its special characteristics will be further discussed.
