Magnetism is a non contact force. This is brcause magnetism “acts on an object without being in physical contact with it”
Answer:
Mass of Fe produced = 44.7 g
Explanation:
Given data:
Mass of Fe produced in gram = ?
Mass of FeO react = 57 g
Solution:
Chemical equation:
2Al + 3FeO → 3Fe + Al₂O₃
Number of moles of FeO:
Number of moles = mass/ molar mass
Number of moles = 57 g/ 71.844 g/mol
Number of moles = 0.8 mol
Now we will compare the moles of Fe with FeO from balance chemical equation.
FeO : Fe
3 : 3
0.8 : 0.8
Mass of Fe:
Mass = Mass × molar mass
Mass = 0.8 mol × 55.845 g/mol
Mass = 44.7 g
I’m not 100% sure but I think it’s 1098
Explanation:
Potassium and Sodium are both metals on the periodic table. Both elements are found on the s-block of the table. Therefore, it is not possible for both of them to combine to form a compound.
For a compound to form two elements must combine in a definite order to given single product.
The combination is facilitated by a loss, gain or sharing of electrons between two species. This leads to an attraction between the combining species.
Both Sodium and potassium would prefer to lose electrons and there is no reason for them to combine to form a compound.
Answer:
The atria and ventricles work together, alternately contracting and relaxing to pump blood through your heart. The electrical system of your heart is the power source that makes this possible.
Your heartbeat is triggered by electrical impulses that travel down a special pathway through your heart:
