Answer:
sulfur will form an ion with negative charge
yes its ionic. thats too big of a difference for it to be any type of covalent or metallic.
Answer:
Re=2094,76
Explanation:
For a fluid that circulates inside a straight circular pipe, the Reynolds number is given by:
where (using the international measurement system):
- ρ: density of the fluid [kg/m3]
- v: velocity of the fluid [m/s]
- D: diameter of the pipe through which the fluid circulates [m]
- μ: dynamic viscosity [Pa.s]
To solve the probelm, we just need to replace our data using <u>THE CORRECT UNITS</u> in the Reynolds number equation. So we have:
ρ=1051 kg/m3,
v=34,3 cm/s=0,343 m/s
D=2,15 cm = 0,0215 m
μ = 3,7 cp * 10^-3 Pa.s/1 cp = 3,7*10^-3 Pa.s
Replacing in the main equation:
So the Reynolds number is 2094,76 (note that the Reynolds number is a dimensionless quantity).
Alcohols have higher boiling points than do ethers and alkanes of similar molar masses.
<h3>What is meant by Boiling Point ?</h3>
The temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid is called the boiling point of the substance.
Approximately boiling point of Ethanol: 78.4°C, ether: 34.6°C, ethanes: 68°C
The reason for the difference is that it takes more energy to separate alcohol molecules then it does to separate alkane molecules and ether molecules.
The OH group in alcohol allows molecules to engage in hydrogen bonding.
Therefore Boiling point are in the order ;
Alcohol > alkane > ethers

Answer:
Alpha, Beta, and Gamma particles according to ability to penetrate matter.
Explanation:
- Alpha represent the largest particle which penetrates the least with a positive charge,
- Beta particles carry a negative charge, and
- Gamma rays are neutral.
