the answer is C
''number of atoms in each compound in a reaction.''
Explanation:
its a fact
Answer: The energy of the products exceeds the activation energy threshold.
Explanation:
In the reverse reaction, the reactants of the forward reaction are now the products of the reverse reaction and vice versa.
This means that normally since you would need the energy of the reactants of the forward reaction to exceed the activation energy threshold, in the reverse reaction, the energy of the products would need to exceed the activation energy threshold.
Answer:
Explanation:
1. Mass of zinc
The density of zinc is 7.14 g/cm³
D = m/V
2. Volume of aluminium
The density of aluminium is 2.60/cm³.
The answer is NO
N has 5 valence electrons
O has 6
Therefore combined there is 11 electrons so they will never complete the octet
The balanced equation that shows the reaction between oxalic acid and permanganate ion in an acidic medium is: 2MnO4- + 5H2C2O4 + 6H+ -> 2Mn(2+) + 10CO2 + 8H2O. Thus, 1 mole of oxalic acid reacts with 0.4 mole of permanganate ion. This was obtained using stoichiometry:
1 mol H2C2O4 x (2 mol MnO4-/ 5 mol H2C2O4) = 0.4 mol MnO4-
In this redox reaction, the permanganate is reduced to manganese(II) ion.
