the metal loses electrons to become a positively charged cation
Explanation:
What is the question is it a fill in the blank multiple choice?
Answer:
34.9 g/mol is the molar mass for this solute
Explanation:
Formula for boiling point elevation: ΔT = Kb . m . i
ΔT = Temperatures 's difference between pure solvent and solution → 0.899°C
Kb = Ebullioscopic constant → 0.511°C/m
m = molality (moles of solute/1kg of solvent)
i = 2 → The solute is a strong electrolyte that ionizes into 2 ions
For example: AB ⇒ A⁺ + B⁻
Let's replace → 0.899°C = 0.511 °C/m . m . 2
0.899°C / 0.511 m/°C . 2 = m → 0.879 molal
This moles corresponds to 1 kg of solvent. Let's determine the molar mass
Molar mass (g/mol) → 30.76 g / 0.879 mol = 34.9 g/mol
Answer:
A system is a collection of elements or components that are organized for a common purpose. ... All of nature and the universe can be said to be a system. We've coined a word, ecosystem, for the systems on Earth that affect life systems. The term can be very useful because so many things can be described as systems.
6 ! 1ml=1cm3 (the metric systems great like that !)
