Answer:
because moles is the chemical unit*Avogadro's number, meaning it's the amount of atoms in the given unit.
Explanation:
Answer:
Newton believed that gravity was a force.
The law of universal gravitation offers a mathematical explanation for the attraction between the moon and Earth.
Newton was the first to have the idea that gravity is everywhere.
Answer:
Supersaturated solution.
Explanation:
Hello!
In this case, according to the types of solution in terms of the relative amounts of solute and solvent, we can define a point called solubility at which the amount of solute is no longer dissolved in the solvent; thus, a value of solute/solvent less than the solubility is related to unsaturated solutions, equal to the solubility is related to the saturated solutions and more than the solubility to supersaturated solutions.
Thus, since solubility is temperature-dependent, at 30 °C the solubility of sodium chloride is 36.09 g per 100 mL of water; which means that, since the solution has 50 g of sodium chloride, more than 36.09 g, we infer this is a supersaturated solution.
Best regards!
Answer:
The mass remains same after and before the reaction
Explanation:
This is because of law of conservation of mass
Which states that
- In a chemical reaction mass is neither created nor destroyed,it remains conserved .
