Answer:

Part A:

"360 grams of NaCl can be dissolved in 1 L water. So, 2000 grams sugar can be dissolved in 1 L water then we can say that the solubility of salt is lesser in water as to sugar and both heightened by increasing the temperature. If we make a batch of 800 L we can add sugar, 1600 kg at 25 0c. We can add salt is 288 kg at 25 0c and the ingredient tomato is having low solubility."

Tomato soup is made of the following ingredients:

In order to make tomato soup, the salt NaCl is first added, then followed by sugar. This is to ensure increase in the boiling point of water and to reduce the heating time of the tomato soup.

The solution is heated to induce more dissolution if solute and finally the tomato powder is added.

In order to optimize the manufacturing process, changes should be made in the design, supply and composition of the soup.

Therefore, an optimized manufacturing process will reduce cost of production.

Answer:

V = 25.7 L.  

Explanation:

Hello there!

In this case, according to the given information, it turns out possible for us to solve for the volume of hydrogen, by firstly calculating the moles of this gas produced by 37.6 g of magnesium, according to the 1:1 mole ratio between them:

[tex]n_{H_2}=37.6gMg*\frac{1molMg}{24.305gMg}*\frac{1molH_2}{1molMg}=1.55molH_2[/tex]

Now, we use the ideal gas equation:

[tex]PV=nRT[/tex]

To solve for the volume, and obtain:

[tex]V=\frac{nRT}{P}\\\\V=\frac{1.55mol*0.08206\frac{atm*L}{mol*K}*293.15K}{1.45atm}\\\\V=25.7L[/tex]

Answer:

Disrupted food webs

increased competition

disrupted life-cycle events

forced relocation

Explanation:

Global warming refers to a gradual rise in the temperature of the earth due to the increase in the concentration of greenhouse gases in the atmosphere which trap infrared radiation close to the earth.

This gradual increase in the temperature of the earth often have devastating effects on the lives of various organisms on earth. These effects include;

Disrupted food webs

increased competition

disrupted life-cycle events

forced relocation

Due to changes that occur in the ecosystem as a result of global warming, many species may be compelled to relocate from place to place. This in turn disrupts food webs and may lead to disruption of life cycle events of the concerned organisms. Decrease in the number of certain populations due to global warming may lead to increased competition among species for food.

Friendship is, in many respects, a "comfortable" love relationship. Friendships involve as little or as much intimacy as the partners are inclined to express at any given time. Friends are not normally obligated to exchange benefits, but do so in ways that are often so natural as to be unwitting. The ties that bind them are by unfettered mutual consent. In spite of its being so comfortable, in fact because of it, friendship contributes in unique ways .

Se administran 2500 gramos de solución por día.

Explanation:

Dado

Volumen de la solución = 2,5 litros

Como sabemos 1 litro = 1000 gramos

Por lo tanto, 2.5 litros = 2500 gramos

Se administran 2,5 litros en un intervalo de 24 horas o 1 día.

De ahí que se pueda decir que se administran 2500 gramos de solución al día.

Answer:

The final volume is 6.4 L.

Explanation:

Dilution is reducing the concentration of a chemical and is achieved by adding more solvent to the same amount of solute. In other words, dilution is the procedure that is followed to prepare a less concentrated solution from a more concentrated one, and it simply consists of adding more solvent.

In a dilution the amount of solute does not vary, and as only more volume (and mass) of solvent is being added, the concentration of the solute decreases.

In a dilution the expression is used:

Ci*Vi = Cf*Vf

where:

In this case:

Replacing:

8 M* 2 L= 2.5 M* Vf

Solving:

[tex]Vf=\frac{8 M* 2 L}{2.5 M}[/tex]

Vf=6.4 L

The final volume is 6.4 L.

Answer:

The initial  E°  for the second cell is the same as for the first cell.

Explanation:

Because the overall chemical reaction that occurs in the cell does not change.

The first galvanic cell generated the cell potential of +1.10 V. The second galvanic cell generates the same cell potential because the overall cell reaction remains the same.

The galvanic cell is given as the electrochemical cell that generates the exchange of chemical and electrical energy.

The cell potential is described as the rate of reaction with the difference in the potential of the cathode and the anode.

The reduction and the oxidation potential are governed by the number of electrons transferred in the chemical reaction.

In the second galvanic cell, the number of electrons transferred from the copper electrode will be equivalent to the first electrode, as the chemical reaction is the same. Thus, the cell potential of the second galvanic cell will be the same as the first cell.

Answer:

D.

HCl is acid

Ca(OH)2 is base

CaCl2 is salt

In the given chemical equation Ca(OH)2 is the base and CaCl2 is the salt, thus  option D is correct.

A chemical equation is a symbolic representation of a chemical reaction that shows the products, reactants, and direction of the reaction.

An acid is any hydrogen-containing substance that is capable of donating a proton (hydrogen ion) to another substance.

A base is a chemical species that donates electrons, accepts protons, or releases hydroxide (OH-) ions in aqueous solution.

A salt, in chemistry, is defined as the product formed from the neutralisation reaction of acids and bases.

Therefore,  in this chemical  equation  option D is true about the equation i.e

Ca(OH)2 is the base and CaCl2 is the salt.
