Answer is A) Al4C3 + 3H2O -> CH4 + 4Al(OH)3
One the left side there are 3 carbon atoms, or moles of carbon, and on the write side there is only one.
In order to solve these problems, count the number of atoms on each side and make sure that for each element, the number of atoms are equal.
For example, for the last problem, we have 1 zinc atom on each sidde, two hydrogen atoms, and two chlorine atoms.
Answer:
physical
Explanation:
if it is asking to determine what it is a sign of or how to identify that characteristic it would be a physical.
Generally, the rate of a reaction will decrease with increasing temperature, although there are some exceptions in the case of non-elementary reactions. However it is more likely that the first statement is false.
Half-life is a measure of the time taken for a to reach 1/2 of its initial concentration, and is generally completely independent of reagent concentration within a first order reaction, which is likely what this reaction is, therefore statement 2 is also likely false.
Hope this helps!
