Answer:
0.47m²
Explanation:
Given parameters:
Length = 9.025 x 10⁶m
Width = 5.215 x 10⁻⁸m
Unknown:
Area of the rectangle = ?
Solution:
Area is the derived from the product of the length and width of a body.
Area = length x width = 9.025 x 10⁶m x 5.215 x 10⁻⁸m
Area = 0.47m²
Answer: Ammonium, when heated with aqueous base, will give off NH3 (ammonia) gas, (and depending, water vapor). This will leave the Cr2O3(s). From then on,
it is just adding or subtraction of gases or water vapor. You probably heard “Loss of electrons is Oxidation”, “Gain of Electrons is reduction”. That should help.
Explanation: This isn’t an explanation but an interesting point; Acid-Base and RedOx reactions are useful to the most complex of any Chemistry. Get this down, and Organic Chemistry will be much easier.
150 grams of water because if 225 grams of propane are burned with 125 grams of oxyegen then there will be 150 grams of water
Answer:
condensation
Explanation:
when gases change to liqud it condenses.This occurs when the temperature is lowered
First, draw the 2-hexene. Th is is a molecule of six carbons with a double bond in the second carbon:
CH3 - CH = CH2 - CH2 - CH2 - CH3
Secong, put one Br on the second carbon and one Br on the third carbon:
CH3 - CBr = CBr - CH2 - CH2 - CH3
Third, cis means that the two Br are placed in opposed positions, this is drawn with one Br up and the other down. So, you need to represent the position of the Br in the space:
H Br H H H
| | | | |
H - C - C = C - C - C - C - H
| | | | |
H Br H H H
The important fact to realize is that the two Br are in opposed sides of the molecule.
