In order to determine the state of the manganese ion, we will look at the anion bonded to it.
MnN, N = -3 so Mn(III)
MnO, O = -2 so Mn(II)
MnBr2, Br = -2 so Mn(II)
Mn2S3, S = -2 so Mn(III)
Mn3P2, P = -3 so Mn(II)
MnI3, I = -3 so Mn(II)

For this question we will have to check the number of protons of each element from the periodic table. After this, we will remove or add electrons until the desired charge is attained (charge is difference between number of protons and electrons) since the number of protons does not change.
K+: protons = 19, electrons = 18
Cl-: protons = 17, electrons = 18
Fe+2: protons = 26, electrons = 24
The moles of B that will be needed to convert 2 moles of A into as many moles of C as possible is 6 moles
Explanation
3A +9B → 5C
The moles of B are calculated using the mole ratio.
That is; from the equation above the mole ratio of A:B is 3:9
If the moles of A required is 2 moles therefore the moles of B
= 2 x9/3= 6 moles
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:
The data shows that a heavier bat produces a faster batted ball speed. This makes intuitive sense since a heavier bat brings more momentum into the collision. ... So, using a heavier bat should result in faster hit balls, which means the hit ball will travel farther.
Explanation:
Tectonic plates, specifically divergent plates, are constantly creating new crust on the surface, pushing the older crust away. Additionally, the mantle has convection cycles that makes hot magma rise, further leading to the crust constantly moving because of that warm lava force.
