what are the physical and chemical properties of bases?

Answers

Answer: Acids are chemical substances which are characterized by a sour taste in an aqueous medium. They have the tendency to turn blue litmus red. On the other hand, bases are chemical substances which are characterized by a bitter taste and are slippery to the touch. Some bases are soluble in water while others are not. Acids give off H+ (Hydrogen) ions in water; bases give off OH- (Hydroxide) ions in water. Acids generally taste sour due to the sour H+ ion; bases taste bitter due to the OH- ion; but they may have other tastes depending on the other part of the molecule. Bases are usually soapy in nature.

Explanation: Acids

Aqueous solutions of acids are electrolytes, meaning that they conduct electrical current. ...

Acids have a sour taste. ...

Acids change the color of certain acid-base indicates. ...

Acids react with active metals to yield hydrogen gas. ...

Acids react with bases to produce a salt compound and water.

Acids taste sour, conduct electricity when dissolved in water, and react with metals to produce hydrogen gas. Certain indicator compounds, such as litmus, can be used to detect acids. Acids turn blue litmus paper red. The strength of acids is measured on the pH scale.

What is a mole of something? Why do scientists use the concept of a mole?

Answers

Answer: A mole is a chemical unit to measure mass of substance.

Explanation:

A mole can be defined as 6.02214076 × 1023 of atoms, ions, molecules and others. A mole is the total amount of discrete entity within a substance present in the form of atoms, ions, and molecules. As atoms, ions, molecules are small entities within any substance so it is necessary to measure each of them and recognize them so the scientists development the concept of mole. It is the convenient unit of measurement because of the presence of greater number of molecules, atoms, and ions present in any substance.

Answer:

The mole is an SI unit used to measure the amount of any substance. One mole is exactly 6.02214076×10 23 particles.

Explanation:

The concept of the mole is important for scientists because it means that one mole of any element has exactly the same number of atoms as one mole of any other element. This information allows chemists to count atomic particles for even very complex chemistry formulas and reactions.

A gas occupies occupies a volume of 0.2 L at 76 mmHg. What volume will the gas occupy at 760 mmHg?

Answers

Answer:

0.02

Explanation:

To solve this problem we use the Boyle's law equation

P1V1 = P2V2

P1 = 76mmHg

V1 = 0.2L

P2 = 760mmHg

V2 = unknown

Substituting values into the equation;

76mmHg * 0.2L = 760mmHg * v2

15.2 = 760V2

Divide through by 760 to get v2

15.2/760 = 0.02

So the gas will occupy a volume of 0.02 at 760mmHg

More bushes of potatoes will be produced if the soil is fertilized more WHAT IS THE INDEPENDENT VAIRABLE AND THE DEPENDENT VARIABLE

Answers

Answer:

The dependent variable is the bushes of potatoes while the soil is an independent variable.

Explanation:

An experiment can be defined as an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).

This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.

Cause and effect can be defined as the relationship between two things or events in which an occurrence one (cause) leads to the occurrence of another (effect).

In an experiment , the variable being manipulated by an experimenter is known as an independent variable while the dependent variable is the event expected to change when the independent variable is manipulated.

Hence, the dependent variable is the bushes of potatoes while the soil is an independent variable.

Chlorine and hydrogen gas react to form hydrogen chloride as shown in the following reaction: Cl 2 (g)+H 2 (g) 2HCl (g) If a 48.5 L sample of chlorine gas was reacted with excess hydrogen at 450 K and 1.20 atm , how many grams of hydrogen chloride is produced ?

It’s 1.58 moles

Answers

Answer:

H

Explanation:

Approximately 1229.80 grams of hydrogen chloride (HCl) is produced.

We must use the specified number of moles of the limiting reactant, in this case chlorine gas [tex](Cl_2)[/tex], to calculate the mass of hydrogen chloride (HCl) produced during the reaction. We can see from the balanced equation that 1 mole of [tex]Cl_2[/tex] results in the formation of 2 moles of HCl.

Given:

Volume of Cl2 gas = 48.5 L

Temperature (T) = 450 K

Pressure (P) = 1.20 atm

Moles of Cl2 = 1.58 moles

The ideal gas law equation can be used to calculate the amount of HCl produced:

PV = nRT

Where:

P = pressure

V = volume

n = moles

R = ideal gas constant

T = temperature

First, we must use the ideal gas law equation to obtain the amount of HCl in moles:

n(HCl) = (P * V) / (R * T)

Using the known values:

P = 1.20 atmV = 48.5 LR = 0.0821 L·atm/(K·mol)T = 450 K

n(HCl) = (1.20 atm * 48.5 L) / (0.0821 L·atm/(K·mol) * 450 K)

≈ 33.73 moles

To the nearest two decimal places, the mass of HCl is equal to its molar mass times its molar mass, or 33.73 mol times 36.46 g/mol, or 1229.80 g.

Mass of HCl = moles of HCl * molar mass of HCl

= 33.73 moles * 36.46 g/mol

≈ 1229.80 grams (rounded to two decimal places)

Therefore, approximately 1229.80 grams of hydrogen chloride (HCl) is produced.

Sodium chloride, NaCl, can be used to melt snow. How many moles of sodium chloride are in a 10 kg bag?

Answers

Answer:

171 moles of sodium chloride

Explanation:

Number of moles = mass/molar mass

Molar mass of sodium chloride = 58.5 g/mol

mass of sodium chloride = 10 Kg or 10,000 g

Now, to obtain the number of moles of sodium chloride;

Number of moles = 10,000 g/58.5 g/mol

Number of moles = 171 moles of sodium chloride

What is a chemical change?

Chemical changes are defined as changes which occur when a substance combines with another substance to form a new substance.Alternatively, when a substance breaks down or decomposes to give new substances it is also considered to be a chemical change.

There are several characteristics of chemical changes like change in color, change in state , change in odor and change in composition . During chemical change there is also formation of precipitate an insoluble mass of substance or even evolution of gases.

There are three types of chemical changes:

1) inorganic changes

2)organic changes

3) biochemical changes

During chemical changes atoms are rearranged and changes are accompanied by an energy change as new substances are formed.

Sulfuric acid reacts with aluminum hydroxide by double replacement producing aluminum sulfate and water Write chemical reaction. If 30 g of sulfuric acid reacts with 25 g of aluminum hydroxide, identify the limiting reactant?

Answers

Answer: [tex]H_2SO_4[/tex] is the limiting reagent.

Explanation:

A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.  

The balanced chemical equation is:

[tex]3H_2SO_4(aq)+2Al(OH)_3(aq)\rightarrow Al_2(SO_4)_3(aq)+6H_2O(l)[/tex]

To calculate the moles :

[tex]\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}[/tex]    

[tex]\text{Moles of} H_2SO_4 =\frac{30g}{98g/mol}=0.31moles[/tex]

[tex]\text{Moles of} Al(OH)_3=\frac{25g}{78g/mol}=0.32moles[/tex]  

According to stoichiometry :

3 moles of [tex]H_2SO_4[/tex] require = 2 moles of [tex]Al(OH)_3[/tex]

Thus 0.31 moles of [tex]H_2SO_4[/tex] will require=[tex]\frac{2}{3}\times 0.31=0.21moles[/tex]  of [tex]Al(OH)_3[/tex]

Thus [tex]H_2SO_4[/tex] is the limiting reagent as it limits the formation of product and [tex]Al(OH)_3[/tex] is the excess reagent.
