Answer;
FeSO4 (aq) + H2 (g)
Explanation;
The reaction between iron and dilute sulfuric acid gives a salt and hydrogen gas. (iron (ii) sulfate and hydrogen gas).
The equation for the reaction is;
Fe(s) + H2SO4 (aq) = FeSO4(aq) +H2(g)
Answer:
carbon-12 is not radioactive
Explanation:
The measurement of the age of dead carbon based life forms requires the use of a radioactive isotope hence it is often referred to as radiocarbon dating.
Carbon-12 and Carbon-14 occur together in living things.The half life of Carbon-14 is about 5670 years.
Hence, since Carbon-12 is not radioactive, it can not be used to measure the age of dead carbon based materials.
Answer:
200 kPa
(it is actually 199.999, but rounding up it is 200)
hope this helps!
