Answer:
Balanced chemical equation:
SeCl₆ + O₂ → SeO₂ + 3Cl₂
Explanation:
Chemical equation:
SeCl₆ + O₂ → SeO₂ + Cl₂
Balanced chemical equation:
SeCl₆ + O₂ → SeO₂ + 3Cl₂
The above equation is balanced. There are one Se, six chlorine and two oxygen atoms are present on both side of equation The given balanced equation followed the law of conservation of mass.
Law of conservation of mass:
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
For example:
In given photosynthesis reaction:
6CO₂ + 6H₂O + energy → C₆H₁₂O₆ + 6O₂
there are six carbon atoms, eighteen oxygen atoms and twelve hydrogen atoms on the both side of equation so this reaction followed the law of conservation of mass.
Answer:
Ozone layer depletion is the thinning of the ozone layer present in the upper atmosphere. This happens when the chlorine and bromine atoms in the atmosphere come in contact with ozone and destroy the ozone molecules. One chlorine can destroy 100,000 molecules of ozone. It is destroyed more quickly than it is created
Answer:
1. provide habitats and shelter for many marine organisms 2. Coral reefs protect coastlines from storms and erosion 3. provide jobs for local communities
Explanation:
37.8 g CH2Br2 X (1 mol CH2Br2 / 173.83 g) = 4.60X10^-3 mol CH2Br2
<span>4.60X10^-3 mol CH2Br2 X (2 mol Br / 1 mol CH2Br2) X 6.02X10^23 atoms/mol = 5.54X10^21 bromine atoms.
