Phase 3 is the integration phrase
Answer:
Option D) Compound B may have a lower molecular weight.
Explanation:
Compound A and B are standing at the same temperature yet compound A is evaporating more slowly than compound B.
This simply indicates that compound B have a lower molecular weight than compound A.
This can further be seen when gasoline and kerosene are placed under same temperature. The gasoline will evaporate faster than kerosene because the molecular weight of the gasoline is low when compared to that of the kerosene.
Explanation:
A column on the periodic table represents a period.
These are some of the variations observed across a period;
- Atomic radii decreases progressively from left to right due to the progressive increase in the nuclear charge without an attendant increase in the number of electronic shells.
- Ionization energy increases progressively from left to right due to decreasing atomic radii.
- Electronegativity increases from left to right.
- Electropositivity decreases across a period.
I think the answer would be 1.58 g.
Electrolysis is the process of applying an electrical current to a solution in order to separate the components of that liquid phase solution on the basis of their charge. If we consider molten calcium hydroxide, the ions present will be:
Ca⁺²
OH⁻
The cations, the ones with a positive charge, will be reduced at the cathode. Therefore, calcium metal will be produced at the cathode. The anions will be oxidized at the anode, which means hydrogen gas will be produced at the anode.
