Answer: Yes, the solute is a weak electrolyte
Explanation:
Depression in freezing point is given by:
= Depression in freezing point
i= vant hoff factor = ?
= freezing point constant = 
m= molality
As i for non electrolytes is 1, the given compound must be an electrolyte and a weak electrolyte as the value is only slightly greater than 1.
D-Carbon Dioxide
Hope this helps :)
A) a resistor, which converts some electric energy to thermal energy.
In this question, the <span>patient needs to be given exactly 500 ml of a 5.0%. The content of the glucose should be:
</span>weight= volume * density* concentration<span>
500ml * 1mg/ml *5%= 25mg.
The </span><span>stock solution is 35%, then the amount needed in ml would be:
weight= volume * density* concentration
25mg= volume * 1mg/ml *35%
volume= 25/35%= 500/7= 71.43ml</span>
Answer:
The effective nuclear charge for a 2nd row electron in Sulfur is +8
Explanation:
Zeff = Z (# of protons) - S (# of shielded electrons)
Since there are 8 electrons in the first and second rows combined, there are 8 shielding electrons.
The number of protons in Sulfur is 16.
Therefore,
Zeff = 16 - 8
Zeff = 8
(It's been awhile, so I am not 100% sure)
