Answer: Water is SUPER soluble and regarded as an universal solvent because it is polar in nature and dissolves most inorganic solutes and some polar organic solutes to form aqueous solutions.
Explanation:
WATER is a substance which is composed of the elements such as hydrogen and oxygen that are combined in the ratio of 2:1. The physical properties of water include:
--> it is a colourless, odourless and tasteless liquid and
--> the boiling point of water is 100°C(this is due to the presence of hydrogen bonding).
The solubility of a solute in a solvent at a particular temperature is the maximum amount of solute in moles or grams that will saturate 1000 dm³ or grams of the solvent.
Water is regarded as a universal solvent BECAUSE it is capable of dissolving many substances. This solubility helps maintain different processes in life such as acting as the solvent which helps cells transport and use substances like oxygen or nutrients.
Answer:
2
Explanation:
As only 2 electrons can present in an orbital, so only 2 electrons in an atom can have this set of quantum numbers.
Answer:
false
Explanation:
this is because , high temperature speeds up the the random motion of particles which leads to high dissolution
Answer:
The work is -6,497.54 J
Explanation:
Work is the amount of energy transferred from one system to another by a force when a displacement occurs.
The work exchanged for a gas depends on the transformation it performs to go from the initial state to the final state.
The pressure - volume work done by a system that compresses or expands at constant pressure is given by the expression:
W= -P*ΔV
where
- W is the work exchanged by the system with the environment. Its unit of measure in the International System is the joule (J), which is equivalent to Pa*m³
- P: Pressure. Its unit of measurement in the International System is the pascal (Pa).
- ∆V: Volume variation (∆V = Vfinal - Vinitial). Its unit of measurement in the International System is cubic meter (m³)
In this case:
- Wsystem=?
- P= 5.63 atm=570,459.8 Pa (being 1 atm=101325 Pa)
- ΔV=Vfinal - Vinitial= 15.61 L - 4.22 L= 11.39 L= 0.01139 m³ (being 1 L=0.001 m³)
Replacing:
W= -570,459.8 Pa*0.01139 m³
Solving:
W=-6,497.54 J
<u><em>The work is -6,497.54 J</em></u>
Answer:
I will need six (6) bags of potting soil
Explanation:
Since you plan on planting in 10 pots and need 15 cups of potting soil per pot, the total amount of potting soil you need <em>(in cups)</em> is 10 X 15 = 150 cups of potting soil.
We have that a bag contains 25 sups. to get the number of bags needed, we have to divide 150 by 25. This will give us 150 / 25 = 6 bags.
Therefore, I will need six (6) bags of potting soil
