Explanation:
Cu, Na and Nd are all elements.
A compound consists of at least 2 different elements.
Calcium chloride (CaCl2) consists of calcium and chlorine atoms, therefore it is a compound.
The empirical formula for the unknown compound would be: C2H4O (2 molecules of Carbon, 4 molecules of Hydrogen, and 1 molecule of Oxygen)
35°c is equal to 95°f
To do this multiply 35 and 1.8
35 x 1.8=63
Now add 32
Resulting in the answer 95
(The equation for to solve for c and f is c1.8+32=f
