<u>Answer:</u> The amount of energy released by the reaction is ![3.47\times 10^{14}J](https://tex.z-dn.net/?f=3.47%5Ctimes%2010%5E%7B14%7DJ)
<u>Explanation:</u>
To calculate the energy released, we use Einstein equation, which is:
![E=\Delta mc^2](https://tex.z-dn.net/?f=E%3D%5CDelta%20mc%5E2)
where,
= difference between the masses of products and reactants = 3.86 g = 0.00386 kg (Conversion factor: 1 kg = 1000 g)
c = speed of light = ![3\times 10^8m/s](https://tex.z-dn.net/?f=3%5Ctimes%2010%5E8m%2Fs)
Putting values in above equation, we get:
![E=(3.86\times 10^{-3}kg)\times (3\times 10^8m/s)^2](https://tex.z-dn.net/?f=E%3D%283.86%5Ctimes%2010%5E%7B-3%7Dkg%29%5Ctimes%20%283%5Ctimes%2010%5E8m%2Fs%29%5E2)
![E=3.47\times 10^{14}J](https://tex.z-dn.net/?f=E%3D3.47%5Ctimes%2010%5E%7B14%7DJ)
Hence, the amount of energy released by the reaction is ![3.47\times 10^{14}J](https://tex.z-dn.net/?f=3.47%5Ctimes%2010%5E%7B14%7DJ)
When a light is on, it is part of a "closed" circuit.
The problem or issue in a human or natural environment caused by chemical reactions would be smog. It is a kind of air pollution, originally named for the mixture of smoke and fog in the air. <span>The atmospheric pollutants or gases that form </span>smog <span>are released in the air when fuels are burnt. When sunlight and its heat react with these gases and fine particles in the atmosphere, it is formed.</span>
Answer:
For CO2 there is one atom of carbon and two atoms of oxygen.
Explanation:
Answer:
The general formula for an acid is HnX where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).
Explanation:
The general formula for an acid is HnX) where H stands for hydrogen, n stands for the number of hydrogen ions, and X stands for the monatomic or polyatomic ions ( since those are negative charged ions, they are called anions).
An example is H2SO4, also called sulfuric acid
It shows that H2SO4 has 2 hydrogen atoms, so in the formula HnX n=2
X fro H2SO4 is SO42-, it's a polyatomic ion. Since it has a negative charge of 2- it needs 2 hydrogen atoms to bind and form H2SO4
