Answer:
Always carry the microscope with two hands. One on the arm and one underneath the base of the microscope.
Answer:
Kb is termed as Ebullioscopic constant.
Explanation:
According to Boiling point elevation phenomenon, any solution will be exhibiting higher boiling point compared to its pure solvent. So this increase in the boiling point of any liquid when a solute is added in the host is termed as boiling point elevation phenomenon. Thus, the boiling point elevation should be related with the molality of the solution b . So the ratio of increase in the boiling point or the boiling point elevation temperature to the molality of the solution gives a constant termed as ebullioscopic constant and denoted as Kb. In other words, we can state the boiling point elevation temperature is directly proportional to the molality of solution with Kb as proportionality constant.
Answer is: 3. Water and carbon dioxide should both be moved to the products side, and glucose and oxygen should be moved to the reactants side.
Balanced chemical reaction for cellular respiration (convert biochemical energy):
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy, or:
glucose + oxygen → carbon dioxide + water + energy.
This reaction is exothermic (energy is released).
Answer:
a lithium atom (Z=3, A=7 AMU) contains three protons (found from Z), three electrons (as the number of protons is equal to the number of electrons in an atom), and four neutrons (7 – 3 = 4).
Explanation:
It’s is a pure substance because nothing is mixed with it and a molecule gas because it’s is a gas and it’s by its self
