Answer:
See below!
Explanation:
Chlorine is very electronegative, meaning that it will pull electrons, or negativity toward itself. When it pulls the negativity towards itself, the chlorine becomes partially negative and the carbon becomes partially positive. Because of this, the compound is polar.
I believe the correct answer would be the third option. It is the burette that is the apparatus that is used in titration. It is the best apparatus to use since you can easily control the amount you add to the sample solution. Also, you can easily read off the volume that was added.
Answer:
A cation is formed when a metal ion loses a valence electron while an anion is formed when a non-metal gains a valence electron. They both achieve a more stable electronic configuration through this exchange.
Answer: The partial pressure of oxygen is 76.56 atm , partial pressure of carbon dioxide is 10.44 atm and the total pressure is 87 atm.
Explanation:
According to the ideal gas equation:'
P = Pressure of the gas = ?
V= Volume of the gas =
T= Temperature of the gas = 10°C = 373 K
R= Gas constant = 0.0821 atmL/K mol
n= moles of gas= 0.25 +0.034 = 0.284 moles
= mole fraction of oxygen=,
=mole fraction of carbon dioxide=
partial pressure of oxygen =
partial pressure of carbon dioxide=
The partial pressure of oxygen is 76.56 atm , partial pressure of carbon dioxide is 10.44 atm and the total pressure is 87 atm.
Answer:
2-methylpropan-2-ol
Explanation:
In this case, we can start with a linear structure of 3 carbons. In carbon 2 we can put a methyl group (). In this same carbon we can put the "OH" group and we will obtain "<u>2-methylpropan-2-ol</u>".
In this molecule, the central atom has 3 bonds with another carbons, so, this central atom is a teritary one. Therefore, we will have a <u>tertiary alcohol.</u>
