100.08 is the molecular mass.
Answer:
Mass on Mars = 85 kg
Weight on Mars = 314.041 N
Explanation:
Given that:
Value of the gravitational acceleration on surface of the Mars is 0.377 times that on the Earth.
Which means that:
Mass does not depend on gravity
<u>Thus, mass on Mars is same as Mass of Earth = 85 kg</u>
<u>Weight on Mars = 85 kg × 3.6946 m/s² = 314.041 N</u>
Types of Bonds can be predicted by calculating the
difference in electronegativity.
If, Electronegativity difference is,
Less
than 0.4 then it is Non Polar Covalent
Between 0.4 and 1.7 then it is Polar Covalent
Greater than 1.7 then it is Ionic
For Ca and K,
E.N of Calcium = 1.00
E.N of Potassium = 0.82
________
E.N Difference 0.18 (Non Polar Covalent)
For Ca and Mg,
E.N of Magnesium = 1.31
E.N of Calcium = 1.00
________
E.N Difference 0.31 (Non Polar Covalent)
For Ca and Br,
E.N of Bromine = 2.96
E.N of Calcium = 1.00
________
E.N Difference 1.96 (Ionic)
For Ca and S,
E.N of Sulfur = 2.58
E.N of Calcium = 1.00
________
E.N Difference 1.58 (Polar Covalent)
Result:
The bond between Calcium and Bromine is Ionic in Nature.
Answer:
Reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.RT
