Electron was discovered by J. J. Thomson in 1897 when he was studying the properties of cathode ray.
Answer:
Covalent solids, also called network solids, are solids that are held together by covalent bonds. As such, they need localized electrons (shared between the atoms) and therefore the atoms are arranged in fixed geometries. Distortion far from this geometry can only occur through a breaking of covalent sigma bonds.
Answer:
Define Transportation in plants: Transportation in plants is when the plant transports water and other mineral throughout the whole plant from the roots to the stem and finally specific parts of a plant.
Define Respiration In Plants: Is when plants use photosynthesis to make their own food to make energy for the plant's growth
Use the atomic weights of H and Cl to calculate the answer to
question 7. For H, it is 1. For Cl it is 35.45.
<span>The
ratio of H to Cl in HCL is 1:1. Therefore, 16.2 grams of H means that there
will be 16.2 * 35.45 grams of Cl within the resulting HCl. Therefore, the grams
of HCl will be 16.2 grams + 574.29 grams = 590.5 grams of HCl</span>
Answer:
The answer to your question is Pressure = 5 atm
Explanation:
Data
Volume 1 = V1 = 0.5 l
Pressure 1 = P1 = 1 atm
Volume 2 = V2 = 0.1 l
Pressure 2 = P2 = x
Formula
To solve this problem use the Boyle's equation
V1P1 = V2P2
Solve for P2
P2 = V1P1/V2
Substitution
P2 = (0.5 x 1) / 0.1
Simplification
P2 = 0.5/0.1
Result
P2 = 5 atm
