Electricity and Magnetism are related as electricity can actually make magnetic material (iron, nickel or silver) magnetic. This is called an electro magnet (a temporary magnet created by wrapping coils around a magnetic core (the electricity powers the coils, magnetising the material)).
Answer:
Sr would be the limiting reactant
5 moles
Explanation:
Since the equation is a balanced equation, the coefficient shows how each substance relates to the other in terms of the number of moles.
Reactants would be those on the left hand side of the arrow, while the products would be found on te right and side of the arrow. In this question, the reactants would be Sr and O₂.
Limiting reactant is the reactant that is insufficient; meaning to say that there is not enough of that substance and thus the reaction cannot continue. The other reactant(s) that is not limiting is called the excess reactants.
From the balanced equation, 2 moles of Sr is needed to react with 1 mole of O₂. Thus, if we have 5 moles of each reactant, Sr would be the limiting reactant since for every 1 mole of O₂, there has to be 2 moles of Sr in order for the reaction to proceed. Thus, if we have 5 moles of O₂, we would need 10 moles of Sr.
When we work out the amount of products formed, we look at the number of moles of the limiting reactant. This is because the limiting reactant determines how much is being reacted, while the excess number of moles of the excess reactant will remain unreacted.
For every 2 moles of Sr reacted, 2 moles of SrO would be produced. This means that the mole ratio of Sr to SrO is 1:1. Thus, since 5 moles of Sr has been reacted, 5 moles of the product (SrO) would be produced.
Meteorological instruments are the hardware used to test the condition of the climate at a given time. Every science has its very own interesting arrangements of lab hardware.
The answers are;
2H2+O2===>2H2O
N2+3H2==>2NH3
C3H8+5O2==>4H20+3CO2
CH4+2O2===>CO2+2H2O
2HBr +Fe==>FeBr2 +H2
I hope it helped
