Answer:

1. 1 mole of NaCl.

2. 1 mole of H₂O.

Explanation:

The balanced equation for the reaction is given below:

HCl + NaOH —> NaCl + H₂O

From the balanced equation above,

1 mole of HCl reacted with 1 mole of NaOH to produce 1 mole of NaCl and 1 mole of H₂O.

Next, we shall determine the limiting reactant. This can be obtained as follow:

From the balanced equation above, we can see that 1 mole of HCl reacted completely with 1 mole of NaOH. Therefore, HCl is the limiting reactant and NaOH is the excess reactant since we have 3.6 moles of NaOH.

1. Determination of the amount of NaCl produced from the reaction.

NOTE: The limiting reactant is used to determine the maximum amount produced since all of it is consumed in the reaction.

The limiting reactant is HCl and the amount of NaCl produced can be obtained as follow:

From the balanced equation above, we can see that 1 mole of HCl reacted to 1 mole of NaCl.

Thus, 1 mole of NaCl was produced.

2. Determination of the amount of H₂O produced from the reaction.

From the balanced equation above, it is evident that 1 mole of HCl reacted to produce 1 mole of H₂O.

Thus, 1 mole of H₂O was produced.

Answer:

The usual culprit is burning coal.

Explanation:

This produces a lot of carbon dioxide as well as sulphur dioxide. Other industrial processes, and vehicle emissions, produce similar oxides unless they are 'scrubbed' out. They react with atmospheric moisture to produce acids like carbonic, sulphurous and nitrous acids. Which is then precipitated. It should be remembered that a volcanic eruption has this effect too.

Answer:

Freezing T° of solution is -142.4°C

Explanation:

This excersise is about colligative properties, in this case freezing point depression,

ΔT = Kf . m . i

Where ΔT = Freezing T° of solvent - Freezing T° of solution

Kf = Cryoscopic constant

m = mol/kg (molality)

i = Number of ions dissolved.

Water is not ionic, so i = 1

Let's find out m.

We determine mass of water, by density

498ml . 1 g/mL = 498 g

We convert the mass of water to moles → 498 g . 1mol/18g = 27.6 moles

We determine mass of solvent by density

2500 mL . 0.789 g/mL = 1972.5 g

Notice, we had to convert L to mL to cancel units.

1 cm³ = 1 mL

We convert the mass from g to kg → 1972.5 g . 1kg /1000g = 1.97kg

We determine m = mol/kg → 27.6mol / 1.97kg = 13.9 m

Kf for ethanol is: 1.99 °C/m

Freezing T° for ethanol is: -114.6°C

We replace at formula: - 114.6°C - Freezing T° solution = 1.99 °C/m . 13.9 m . 1

- 114.6°C - Freezing T° solution = 27.8 °C

- Freezing T° solution  = 27.8°C + 114.6°C

Freezing T° Solution = - 142.4 °C

Answer: its D

Explanation: A.P.E.X.

The question is incomplete, the complete question is;

Choose the aqueous solution that has the highest boiling point. These are all solutions of nonvolatile solutes and you should assume ideal van't Hoff factors where applicable. 0.100 m C6H12O6 0.100 m AlCl3 0.100 m NaCl 0.100 m MgCl2 They all have the same boiling point.

Answer:

AlCl3 0.100 m

Explanation:

Let us remember that the boiling point elevation is given by;

ΔTb = Kb m i

Where;

ΔTb = boiling point elevation

Kb = boiling point constant

m = molality of the solution

i = Van't Hoff factor

We can see from the question that all the solutions possess the same molality, ΔTb now depends on the value of the Van't Hoff factor which in turn depends on the number of particles in solution.

AlCl3 yields four particles in solution, hence ΔTb is highest for AlCl3 . The solution having the highest value of ΔTb also has the highest boiling point.

The given reaction is an example of displacement reaction. Here, one mole of oxygen reacts with one mole of oxygen molecules. Hence theoretically 32 g of sulphur needs 32 g of oxygen.

Displacement reactions are a kind of reactions where one element or group is displaced with other element or group. There are both single displacement and double displacement reaction.

The reaction of sulfur oxide with metallic copper producing copper oxide and copper sulphide is an example of single displacement reaction. The prior reaction for this is the combination of sulfur and oxygen.

Here, one mole of oxygen reacts with one mole of oxygen molecules. Hence theoretically 32 g of sulphur needs 32 g of oxygen. Thus each is reacting in 1 :1 ratio and giving the oxide of sulfur.

Atoms are said to be electrically neutral when they have the same number of protons and electrons.

Now, Nitrogen atom has a mass number of 14 and an atomic number of 7. This means that it has 7 number of protons and 7 number of electrons.

From the definition of electrically neutral atoms, it's clear that nitrogen falls into that category.

Answer:

Dihydrogen Monoxide (DHMO) is perhaps the single most prevalent of all chemicals that can be dangerous to human life. Despite this truth, most people are not unduly concerned about the dangers of Dihydrogen Monoxide. Governments, civic leaders, corporations, military organizations, and citizens in every walk of life seem to either be ignorant of or shrug off the truth about Dihydrogen Monoxide as not being applicable to them. In 1997, the Dihydrogen Monoxide Research Division was formed and went online spreading the truth about DIHYDROGEN MONOXIDE. As word has spread, so too has the public awareness of Dihydrogen Monoxide and its implications involving the Internet and accessibility of such information. To that end, the DMRD's web site at DHMO.org continues to provide the most comprehensive collection of Dihydrogen Monoxide information available anywhere.

Explanation:

DHMO has been the dihydrogen monoxide. It has been responsible for the death of males and children as it causes tissue damage.

The DHMO has been the hydric acid and is one of the major constituents of acid rain. Gas has been responsible for greenhouse gas. Ingestion may lead to tissue damage with symptoms of nausea, vomiting, and electrolyte imbalance.

The companies dumping waste in the rivers and lakes have been warned for the removal of DHMO as it has been harmful to the males and children, and results in death.
