Answer:
When temperature increases the volume decreases too
Explanation:
In chemical read tion when the temperature increase it compress the volume of the chemical. I can be measured in degree centi grade
Answer:
1. Chromium
2. Chlorine.
3. Chlorine.
4. Chromium.
5. 12 electrons.
Explanation:
Hello,
In this case, the given reaction with the appropriate oxidation states turns out:
In such a way, the oxidation half-reaction is written for chromium as the reducing agent so it is oxidized from +3 to +6, nonetheless, since there are two chromiums undergoing such change, 6 electrons are being transferred as shown below:
On the other hand, chlorine's reduction half-reaction as the oxidizing agent result from the transfer of 6 electrons as well from +1 to 0, nonetheless, there are 6 chlorines undergoing such change:
Therefore, there are 12 electrons that are being transferred, 6 for chromium and 6 for chlorine.
Best regards.
Answer:
The new volume of a gas at 750 mmhg and with a volume of 2. 00 l when allowed to change its volume at constant temperature until the pressure is 600 mmhg is 2.5 Liters.
Explanation:
Boyle's law states that the pressure of a given amount of gas is inversely proportional to it's volume at constant temperature. It is written as;
P ∝ V
P V = K
P1 V1 = P2 V2
Parameters :
P1 = Initial pressure of the gas = 750 mmHg
V1 = Initial pressure of the gas = 2. 00 Liters
P2 = Final pressure of the gas = 600 mmHg
V2 = Fimal volume of the gas = ? Liters
Calculations :
V2 = P1 V1 ÷ P2
V2= 750 × 2. 00 ÷ 600
V2 = 1500 ÷ 600
V2 = 2.5 Liters.
Therefore, the new volume of the gas is 2. 5 Liters.
Answer:
The Columbus Day Storm of 1962 (also known as the Big Blow,[2] and originally as Typhoon Freda) was a Pacific Northwest windstorm that struck the West Coast of Canada and the Pacific Northwest coast of the United States on October 12, 1962. It is considered the benchmark of extratropical wind storms. The storm ranks among the most intense to strike the region since at least 1948, likely since the January 9, 1880 "Great Gale" and snowstorm. The storm is a contender for the title of most powerful extratropical cyclone recorded in the U.S. in the 20th century; with respect to wind velocity, it is unmatched by the March 1993 "Storm of the Century" and the "1991 Halloween Nor'easter" ("The Perfect Storm"). The system brought strong winds to the Pacific Northwest and southwest Canada, and was linked to 46 fatalities in the northwest and Northern California resulting from heavy rains and mudslides.
