Answer:
The answer is given below
Explanation:
When electronegativity difference arises between the bonded atoms, then a molecule is polar.
When electros are shared equally between the bonded atoms or when the polar bonds in a bigger molecule cancels out each other, then a a molucule is non polar.
(a) 50% isopropanol/H2O,--- 2 (second least polar)
(b) 25% isopropanol/H2O,----- 3 (third least polar)
(c) pure water----- is 4 (most polar)
(d) 70% isopropanol/H2O. 1 (least polar)
Answer:
1.495 moles is the correct answer
Waste produced by each plant : 0.8 tons per month
<h3>Further explanation</h3>
Given
60,000 metric tons of nuclear waste in 60 years of operating 104
nuclear power plants.
Required
Waste produced
Solution
60,000 metric tons=60 years, so in one year :
1000 metric tons/year = 83.33 metric tons/month
For each plant :
Wood is renewable. This is because more trees can always be planted. All the other choices are non-renewable.
Answer: 6.18 g/L
Explanation:
To calculate the density of gas, we use the equation given by ideal gas equation:
Number of moles (n) can be written as:
where, m = given mass
M = molar mass
where,
which is known as density of the gas
The relation becomes:
.....(1)
We are given:
M = molar mass of = 146.06 g/mol
R = Gas constant =
T = temperature of the gas =
P = pressure of the gas = 1 atm
Putting values in equation 1, we get:
Thus density of sulfur hexafluoride gas at exactly 15°C and exactly 1atm is 6.18g/L
