Is it multiple choice if so can you put them down
Notice that each reactant is made up of two elements. To predict the products, all you have to do is interchange the combination of the two reactants while taking note that metal comes first, followed by nonmetals. With that being said, the reaction would be:
CaC₂ + 2 H₂O --> C₂H₂ + Ca(OH)₂
<em>So, the answer is C₂H₂.</em>
Answer:
Explanation:
From the question we are told that:
Frequency 
Generally the equation for Energy of an electromagnetic wave is mathematically given by
Where
h=Planck's constant
Therefore
