This answer is true because it's t same amount
The mass of the ethylene glycol used is 14.26 g
<h3>What is the freezing point?</h3>
The freezing point is the temperature at which a liquid is converted to a solid.
Given that;
ΔT = 0.0°C - ( -4.3°C) = 4.3°C
ΔT = 4.3°C
But we know that
ΔT = k m i
m = ΔT/k i
m = 4.3°C/1.86 °C/m * 1
m = 2.3 m
Now;
Let the mass of ethylene glycol be m
Molar mass of ethylene glycol = 62 g/mol
Mass of solvent = 100.0 g or 0.1 Kg
Then;
2.3= m/62/0.1
2.3 = m/62 * 0.1
m = 2.3 * 62 * 0.1
m = 14.26 g

Answer:
Confine the spill to a limited area. Barricade and isolate the area to prevent spread of contamination.
Pick up broken glass with tongs, forceps, or dustpan. Place the glass into an EHSO dry waste container.
Use appropriate neutralizer and absorbents to mitigate the spill.
Contact EHSO for chemical disposal pick up.
Explanation:
Allow the wound to bleed, but do not massage it to remove any remaining broken glass.
Wash the wound with warm water and soap.
Apply first aid and seek medical attention.
Follow your facility's safety plan if the injury is severe or if you were exposed to infectious materials.
Answer: Order of the elements from most reactive to least reactive is:
Mg > Zn > Fe > H > Cu
Explanation: Reactivity of the elements is the tendency of the elements to loose or gain electrons with ease.
As, all the given elements are metals, so the metals which will loose electrons easily will be more reactive. To study the reactivity of metals, we use reactivity series.
The metals which are more reactive are placed on the top of the reactivity series and which are less reactive are placed at the bottom.
Hence, the order of the elements from most reactive to least reactive is:
Mg > Zn > Fe > H > Cu
Reactivity series is attached below.
