Answer:
Yes
Explanation:
Yes, A substance can be a lewis acid without being a Bronsted-Lowery acid because there are some substances which cannot donate protons(Bronsted-Lowery acid) but can accept a pair of electron.
<u><em>For Example:</em></u>
Let us take the example of BF₃
BF₃ contains no proton so it is not a Bronsted Lowery Acid
However, BF₃ has an incomplete octet with 6 electrons. It needs an electron pair to complete its octet. It accepts a pair of electron to become a Lewis Acid
Answer:
a. It is equal to zero
Explanation:
As the possible results of a continuous random variable are infinite, it is most common to talk about probabilities on intervals; A singular and particular value is so difficult to obtain in an experiment because there are infinite possibilities, and a specific value is just a very little part of the possibilities.
That is the reason why, as a definition, that probability is always zero when you have a continuous random variable.
Answer:
The large relative distances between particles in a gas means that there is considerable empty space between the particles.
The assumption that particles in a gas are relatively far apart explains gas compressibility.
Compressibility is a measure of how much the volume of matter decreases under pressure.
Energy is released by a gas when it is compressed
Explanation:
The kinetic molecular theory establishes that gases are composed of molecules. These molecules of gas are far apart from each other hence there is a considerable empty space between the gas molecules. As a result of these empty spaces between gas molecules, it is possible to compress a gas.
Compressibility is defined as a measure of how much the volume of matter decreases under pressure. When a gas is compressed, work is done on the gas and energy is evolved hence the gas heats up.
Answer:
![Volume = 6.5025cm^3](https://tex.z-dn.net/?f=Volume%20%3D%206.5025cm%5E3)
Explanation:
Given
Initial Form: Onyx
Final Form: Rectangular Solid
Dimension of Solid = 5.10 cm by 5.10 cm by 2.50 mm
Required
Volume of the solid (in cm³)
The volume of a solid is calculated as thus;
![Volume = Length * Width * Height](https://tex.z-dn.net/?f=Volume%20%3D%20Length%20%2A%20Width%20%2A%20Height)
Assume the following;
![Length = 5.10cm\\Width = 5.10cm\\Height = 2.50mm](https://tex.z-dn.net/?f=Length%20%3D%205.10cm%5C%5CWidth%20%3D%205.10cm%5C%5CHeight%20%3D%202.50mm)
The first thing to do is to convert the assumed height from mm to cm
Given that;
![1mm = 0.1cm](https://tex.z-dn.net/?f=1mm%20%3D%200.1cm)
This implies that
![2.50mm = 2.50 * 0.1cm\\2.50mm = 0.25cm](https://tex.z-dn.net/?f=2.50mm%20%3D%202.50%20%2A%200.1cm%5C%5C2.50mm%20%3D%200.25cm)
Hence, the dimension of the solid in cm is:
![Length = 5.10cm\\Width = 5.10cm\\Height = 0.25cm](https://tex.z-dn.net/?f=Length%20%3D%205.10cm%5C%5CWidth%20%3D%205.10cm%5C%5CHeight%20%3D%200.25cm)
The Volume is then calculated as;
![Volume = 5.10cm* 5.10cm * 0.25cm](https://tex.z-dn.net/?f=Volume%20%3D%205.10cm%2A%205.10cm%20%2A%200.25cm)
![Volume = 6.5025cm^3](https://tex.z-dn.net/?f=Volume%20%3D%206.5025cm%5E3)
Hence, the volume of the rectangular solid is ![Volume = 6.5025cm^3](https://tex.z-dn.net/?f=Volume%20%3D%206.5025cm%5E3)
