On the off chance that 888 cloves go into 500mL, at that point 888÷5 ought to go into 500÷5 mL of sauce. This implies, roughly 177.77 cloves of garlic ought to go into 100mL of tomato sauce.

we must increase the cloves required for 100mL by 9. This implies, 177.77×9 cloves of garlic must go into 100×9 mL of sauce.

But as Raphael has utilized 121212 cloves of garlic in 900mL of sauce, which is much, much more than 1600 cloves (which Emily would have utilized), able to say that choice A will be genuine, that's , Emily would fine the sauce as well garlicky.

Emily believes Raphael's tomato sauce is overly garlicky, which may be determined by the unitary method's requirement for the number of garlic cloves.

If 500 mL of sauce contains 888 cloves, then 888 mL of sauce should contain 888 mL of cloves. According to this, there should be about 177.77 garlic cloves per 100 milliliters of tomato sauce. We must add nine more cloves to the 100mL requirement. This suggests that 177.77.9 garlic cloves must be added to 100.09 mL of sauce. But since Raphael used 121212 garlic cloves—more than 1600 cloves—in 900mL of sauce, we may say that option A is the real deal, which means Emily would find the sauce to be overly garlicky.

A buffer is any mechanism that resists changes in ph.

A buffer is a substance that can withstand a pH change when acidic or basic components are added. Small additions of acid or base can be neutralized by it, keeping the pH of the solution largely stable. This is crucial for procedures and/or chemical reactions that call for a range of pH values that is precise and consistent. Strong acids or bases added in small amounts don't cause buffer solutions to change pH. A buffer is something that combines a weak acid and its salt, such as acetic acid and sodium acetate that is CH3COOH and CH3COONa solution.

A Lewis structure, also known as a Lewis dot diagram, is a way to represent the bonding and non-bonding electrons in a molecule. It is named after Gilbert N. Lewis, who introduced it in 1916. A Lewis structure shows the chemical symbol of each atom in the molecule and the electrons that are involved in the chemical bonds. It is used to predict the molecular geometry, reactivity, and other chemical properties of a molecule.

The formal charge on the Nitrogen atom is 0 and each Oxygen atom has a formal charge of -1. A structure that minimizes the formal charge is one in which the formal charges on all the atoms are as close to zero as possible. This can be achieved by using the electrons from the central Nitrogen atom (N) to form single bonds with each Oxygen atom (O)

The salt become less soluble in water when the temperature of the water decreases. Solubility increases with the increase in temperature.

The term solubility is the maximum quantity of solute that can dissolve in a certain quantity of solvent or quantity of solution at a specified temperature or pressure. An increase in temperature produces an increase in solubility. The effect of temperature on solubility can be explained on the basis of Le Chatelier's Principle. This principle is of value in predicting how much a system will respond to a change in external conditions. An increase in temperature puts a stress on the equilibrium condition and causes it to shift to the right. The stress is relieved because the dissolving process consumes some of the heat. Therefore, the solubility increases with an increase in temperature.

In mixture or solution, the ratio of an individual component to the total number of moles is called its mole fraction.

Let n1 be the number of moles of CaCl₂ and n2 be the number of moles of water.

molar mass of CaCl₂ = 111 g

weight = 25.5 g

number of moles = 25.5 /111 g = 0.22 moles.

Mole fraction of CaCl₂ = 0.105

then, n1/ (n1 + n2) = 0.105

0.22/ (0.22 + n2) = 0.105

0.22 = (n2 + 0.22) 0.105

0.105 n2 = 0.1969

n2 = 0.1969 /0.105 = 1.87.

Osmosis is the movement of solvent molecules through a semi-permeable membrane from a solution with a low solute concentration to a solution with a high solute concentration, in order to balance the concentration of the solution.

Three conditions needed for osmosis to occur are:

The disk will float on the surface of the water after making holes. The portion removed from the disk decreases the mass of the disk and becomes lighter.

The floating or sinking of the object is explained by Archimedes' principle. When the weight force on an object is countered by the water's upward push, the thing floats. Water exerts an upward force proportional to the volume of the submerged object. Water depth or volume has no bearing on this upward force. The object will sink if the downward force of the weight is greater than the upward force of the water on it. The thing will rise if the contrary is true because rising is the opposite of sinking.
