Helium is a nonmetal. There are several reasons for this, it is unable to donate electrons and It has an extremely low melting point.
Answer:
Yes
Explanation:
Because it was false because it has been the substance abuse permalink
Answer: Flow rate is inversely proportional to viscosity.
Explanation: The relation is called Poiseuille's law, which describes the smooth flow of a fluid along a tube.
Answer: Energy of reactants = 30, Energy of products = 10
Exothermic
Activation energy for forward reaction is 10.
Explanation:
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and
for the reaction comes out to be negative.
Energy of reactants = 30
Energy of products = 10
Thus as energy of the product < energy of the reactant, the reaction is exothermic.
Activation energy
is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.
for forward reaction is (40-30) = 10.
