Convert the following into balanced equations. ( use the lowest possible ) when gallium metal is heated in oxygen gas, it melts and forms solid gallium(iii) oxide. (b) liquid hexane burns in oxygen gas to form carbon dioxide gas and water vapor. (c) when solutions of calcium chloride and sodium phosphate are mixed, solid calcium phosphate forms and sodium chloride remains in solution.

Explanation:

(a) Balanced reaction of gallium with oxygen is as follows:

(b)

Multiply the carbon dioxide by 6 to balance carbon as follows:

After that multiply H2O by 7 to balance hydrogen as follows:

Finally balance oxygen by multiplying O2 by 19/2. Therefore, balanced reaction is as follows:

(c)

first balance calcium, by multiply by 3 as follows:

After that balance phosphorous by multiplying by 2 as follows:

Finally balance Na by multiplying NaCl by 6. Therefore, balance reaction is as follows:

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
