Answer:
Explanation:
When you are in the laboratory and take a direct sniff of the chemicals you are using, you run the risk of damaging your mucous membranes or your lungs. When it is necessary to smell chemicals in the lab, the proper technique is to cup your hand above the container and waft the air toward your face.

This is a benefit I’m not sure if a negative
This strong current of warm water influences the climate of the east coast of Florida, keeping temperatures there warmer in the winter and cooler in the summer than the other southeastern states. Since the Gulf Stream also extends toward Europe, it warms western European countries as well.
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:
A precipitation reaction produces an insoluble solid as a result of the reaction of two dissolved chemicals in a solution. The insoluble solid, called a precipitate, sinks to the bottom of the solution or stays in suspension as cloudy particles.
