2hf + caoh2 = CaF2 + 2H2O
Acid is 'hf' ; hydrofluoric acid
Base is 'caoh2' ; calcium hydroxide.
NB
When writing chemcial formula , single letter symbols are ALWAYS a CAPITAL letter. Two letter symbols are always ; first letter is a capital letter and the secons letter is small case. This is the internationally agreed standard. Otherwise confusion reigns.
So 'hf' should be 'HF' (Hydrogen(H) and Fluorine(F)
'caoh"' should be 'Ca(OH)2' ( Calcium (Ca) , Oxygen (O) and Hydrogen (H)).
The suffix '2' indicates that there are two hydroxide anions, which are shown in brackets. As written by yourself 'caoh2' indicates 1 x calcium , 1 x oxygen and 2 x hydrogen.
Hope that helps for future reference!!!!

What gas is used up when combustion occurs?
Combustion or burning is the sequence of exothermic chemical reactions between a fuel and an oxidant accompanied by the production of heat and conversion of chemical species.In a complete combustion reaction, a compound reacts with an oxidizing element, such as oxygen or fluorine, and the products are compounds of each element in the fuel with the oxidizing element. For example: CH4 + 2O2 → CO2 + 2H2O CH2S + 6F2 → CF4 + 2HF + SF6A simpler example can be seen in the combustion of hydrogen and oxygen, which is a commonly used reaction in rocket engines: 2H2 + O2 → 2H2O(g) + heatThe result is water vapor.
