The proper word equation  for

 4Fe + 3Sn(NO3)4  = 4Fe(NO3)3 + 3Sn  is as below

Iron + Tin (iv) nitrate =  iron(iii) nitrate + Tin

  iron displaces  tin from it compound ( Tin (iv) nitrate to form iron (iii) nitrate and tin.

from the equation above 4 moles of Fe  displaces  3 moles of Sn(NO3)4 to form 4 moles of Fe(NO3)3 and  3 moles of SN

SVETLANKA909090 [29]

The molarity of a solution is found to be 10 M.

Explanation:

  • Molarity of a solution = <u>moles solute</u>

                                        Litres solution

  • Therefore,M =<u> 50</u>

                        5

  • Molarity of a solution  = 10 M

Someone please help i don’t have much time left
REY [17]

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 \Delta H 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 (E_a) is the extra energy that must be supplied to reactants in order to cross the energy barrier and thus convert to products.

E_a for forward reaction is (40-30) = 10.
