Answer:
New volume = 105.6 mL
Explanation:
Given that,
Temperature, T = 240.0 K
Pressure, P = 670 mm Hg
Volume, V = 128 mL
New temperature = -75°C = 198 K
We need to find the new volume. Let it is V'. The relation between volume and the temperature is given by :
![V=kT\\\\\dfrac{V}{V'}=\dfrac{T}{T'}\\\\V'=\dfrac{VT'}{T}\\\\V'=\dfrac{128\times 198}{240}\\\\V'=105.6\ mL](https://tex.z-dn.net/?f=V%3DkT%5C%5C%5C%5C%5Cdfrac%7BV%7D%7BV%27%7D%3D%5Cdfrac%7BT%7D%7BT%27%7D%5C%5C%5C%5CV%27%3D%5Cdfrac%7BVT%27%7D%7BT%7D%5C%5C%5C%5CV%27%3D%5Cdfrac%7B128%5Ctimes%20198%7D%7B240%7D%5C%5C%5C%5CV%27%3D105.6%5C%20mL)
So, the new volume is equal to 105.6 mL.
Answer:
The correct classification of the statement is all compounds.
Explanation:
- All matter is defined as something that entirely has weight and occupies some sought of space. That's why it can't be used to describe the above statement.
- All elements are defined as substances that have an equal number of protons. The atoms in an element contain an exact atomic number.
- All compounds can be defined as a formation that takes place when a variety of atoms are chemically combined. Hence, this explains the answer above.
- All pure substances mean that the substance is not mixed with anything at all. It's just by itself.
The hybridization will be sp3. I hope that is helpful.
That would be a change in energy. C.
Changes in color, shape, state may or not may occur.
Answer:
D.It restores trees to areas where they once grew.
Explanation:
This is because reafforestation is the process where new tress are planted either natural or intentionally stocking of new tress to areas where the trees has been depleted before or defforested before. It restores new tress to the area or it support the growth of new trees.
