Answer:
six neutrons
Explanation:
there are six neutrons present in C Carbon
Combustion will cause a chemical change in paper.
This is because the carbon compounds are being oxidized into carbon dioxide and water vapour (or h2o, same thing).
Answer:
Synthesis - 4
reversible- 2
exchange- 1
decomposition-3
Explanation:
In synthesis reaction two or more components combines to form a single product. example 2H2+O2⇒2H2O
In reversible reaction two reactants combine to form two products . The products then reacts and forms back the reactants. example N2 +3H2 ⇒2NH3
In exchange reaction there is an alternation of ions of reactants to form new products. AB+CD ⇒AC + BD
In decomposition reaction, molecules of a compound break down by the action of heat or light or catalyst. example CaCO3 ⇒CaO +CO2
the force that pushes magma from the magma chamber through the pipe and vent of a volcano is expanding gases.
Hope this helps you succeed. :D
