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:
According to the subshells, the ns subshell has a sphere-like shape, and on average, lower energy than the rest of the subshells on the same quantum level
The np subshell has two lobes opposite the origin, and on average has more energy than a ns subshell since it has one more angular node, and thus np electrons are less core-like (and further away from the nucleus).
n
d orbitals have five spatial orientations:
and n
f orbitals have seven spatial orientations
The energies are on average in increasing order for the same energy level , n as follows,
nS < nP < nD < nF
Answer:
The correct statements are A amine groups are fully protonated and can be described with the chemical formula NH3+ B carboxylic acid functional groups are de protonated and can be be described with the chemical formula COO- C Amine functional groups are positively.
Explanation:
If we study the biochemical structure of an amino acid we wil see that an amino group or -NH2 is present at one end and a carboxylic group or COOH is present at another end.
Now the fact the that when an amino acid exist as zwitterion it contain same number of positive charge as well as same number of negative charge.So during zwitterion formation the carboxylic acid or -COOH liberates a proton and exist as COO- whereas the amine group accepts that proton and exist as NH3+.
Beside this the amine group -NH2 after the formation of zwitterion gains a positive charge and exist as -NH3+.
Change in size because that just means that more is added rather than anything reacting
Answer:
20
Explanation:
The acceleration in this problem is 20
Acceleration is defined as the rate of change of velocity with time. When a force is exerted on a body and the net force is greater than zero, it begins to accelerate.
- A golf ball often accelerate from rest when being hit.
- Its initial velocity in this instance is usually zero.
- As it is hit, the acceleration increases to a point where it begins to tend towards zero is momentum decreases.
- From the given problem, the mass of the ball is 0.2kg and the acceleration is 20m/s²
