Answer
MnO₄ + 2H⁺ +3NO₂⁻ →3NO₃⁻ + Mn²⁺ +H₂O
Explanation
This is a redox reaction (oxidation-reduction reaction) which involves the transfer of electrons between two species. i.e
Mn + 6e⁻→Mn²⁺ (reduction)
3N³⁺- 6e⁻→3Mn⁵⁺(oxidation)
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. F = ma; a = F/m. This means that Force over the mass. In order to improve the acceleration without redesigning is that the company has to improve the force assuming that the mass is still the same.
Answer: 0.147 grams
Explanation:
To calculate the moles :
According to stoichiometry :
2 moles of 
require = 2 moles of ![NaOH/tex]Thus 0.049 moles of [tex]Al](https://tex.z-dn.net/?f=NaOH%2Ftex%5D%3C%2Fp%3E%3Cp%3EThus%200.049%20moles%20of%20%5Btex%5DAl)
will require=
of 
Thus is the limiting reagent as it limits the formation of product and is the excess reagent.
As 2 moles of give = 3 moles of 
Thus 0.049 moles of give =
of
Mass of 
Thus 0.147 g of will be produced from the given masses of both reactants.
I believe the answer is a compound because compounds can be separated when put together while mixtures can not.
