Answer:
Classification will be Potassium, Bromine, and Argon
Explanation:
- Potassium is more likely to lose electrons and form positive ion
- Bromine actually gain electrons and forms negative ion
- Argon does not lose or gain electrons
Answer:
[HOCH₂CH₂OH] = 24.1 m
Explanation:
Ethylene glycol → HOCH₂CH₂OH
60% by mass means that 60 g of ethylene glycol are contained in 100 g of solution.
Solution mass = Solute mass + Solvent mass
100 g = 60 g + Solvent mass
Solvent mass = 40 g
Molality are the moles of solute contained in 1kg of solvent.
We determine the moles of solute → 60 g . 1mol/62 g = 0.967 moles
We convert the mass of solvent from g to kg → 40 g . 1kg/1000 g = 0.04 kg
Molality → 0.967 mol / 0.04 kg = 24.1 m
Answer:
Independent Variable = Years
Dependent Variable = Number of Mobiles phone owners
Explanation:
Independent variables are plotted on x-axis and the dependent variables are plotted on y-axis.
In given graph the "Years" belong to x-axis hence, years are the independent variables.
Also, "Number of Mobile phones owners" belong to y-axis hence, this number is the dependent variable.
