Will lithium become a cation or anion?

Answers

Answer 1

Answer:

Lithium Cation is a monovalent cation that is metabolized much like sodium and is important in many cellular functions inside or on the surface of cells. lithium has a single valence electron that is easily given up to form a cation. Because of this, lithium is a good conductor of heat and electricity as well as a highly reactive element, though it is the least reactive of the alkali metals

Define activation energy.Activation energy is Define activation energy.the energy barrier that must be surmounted in order for the reactants to transform into products.the energy difference between the reactants and the products.the energy released by the reactants while transforming into products.the energy released by the products while transforming into reactant

Answers

Answer:

the energy barrier that must be surmounted in order for the reactants to transform into products.

Explanation:

When we draw a reaction profile, there is always a hump that is found between the reactants and products. This hump is called the activation energy.

The activation energy of a reaction stands as a sort of barrier between reactants and products which must be surmounted before the reactants are converted into products.

Only reactants that possess the activation energy can be converted from reactants to products.

A base is a substance which neutralizes an acid. Which of these substances is not a base?

A. aqueous ammonia
B. sodium chloride
C. sodium carbonate
D. calcium oxide

Answers

Answer: C
im sorry if its wrong but i already took this in school

Among these, sodium chloride is a substance which is not a base, therefore option (b) is correct.

What do you mean by a base in a chemical reaction?

A base is a chemical species that donates electrons, accepts protons, or releases hydroxide (OH-) ions in aqueous solution. A base is a molecule or ion able to accept a hydrogen ion from an acid.

A strong base completely dissociates into its ions in water. Bases react vigorously with acids and organic matter. Bases react in predictable ways with pH indicators.

A base substance is  a solution that has a pH level of more than 7.  Bases react with acids to form salts which is called neutralization reaction.

Among these  since sodium chloride is not a base, hence option(b) is correct.

Iron(II) sulfide has a molar mass of 87.91 g/mol. 50 grams of
this substance would contain about 3.011 x 1023 molecules.
TRUE
FALSE

Answers

Answer:

true

Explanation:

Answer:

[tex]\boxed {\boxed {\sf False}}[/tex]

Explanation:

We want to know if 50 grams of iron (II) sulfide contains 3.011 * 10²³ molecules.  Let's calculated and check.

1. Convert Grams to Moles

We know there are 50 grams of iron (II) sulfide or FeS If we want to convert from grams to moles, we use the molar mass (mass per 1 mole). This is given to us and it is 87.91 grams per mole for this substance. Let's create a ratio.

[tex]\frac {87.91 \ g \ FeS}{ 1 \ mol \ FeS}[/tex]

We want to convert 50 grams of FeS to moles, so we multiply by this value.

[tex]50 \ g \ FeS *\frac {87.91 \ g \ FeS}{ 1 \ mol \ FeS}[/tex]

Flip the ratio so the grams of FeS cancel.

[tex]50 \ g \ FeS *\frac {1 \ mol \ FeS}{ 87.91 \ g \ FeS}[/tex]

[tex]50*\frac {1 \ mol \ FeS}{ 87.91}[/tex]

[tex]\frac {50}{ 87.91} \ mol \ FeS[/tex]

[tex]0.5687635081 \ mol \ FeS[/tex]

2. Convert Moles to Molecules

1 mole of any substance contains the same number of particles (atoms, molecules, formula units, etc.). This is Avogadro's Number or 6.022 *10²³. In this case, the particles are molecules of FeS. Create another ratio.

[tex]\frac {6.022 *10^{23} \ molecules \ FeS}{ 1 \ mol \ FeS}[/tex]

We want to convert 0.5687635081 moles of FeS to molecules, so we multiply by this value.

[tex]0.5687635081 \ mol \ FeS*\frac {6.022 *10^{23} \ molecules \ FeS}{ 1 \ mol \ FeS}[/tex]

The units of moles of FeS cancel.

[tex]0.5687635081 *\frac {6.022 *10^{23} \ molecules \ FeS}{ 1 }[/tex]

[tex]0.5687635081 *{6.022 *10^{23} \ molecules \ FeS}[/tex]

[tex]3.42509385*10^{23} \ molecules \ FeS[/tex]

If we round to the thousandth place, the 0 in the tenth thousandth place tells us to leave the 5.

[tex]3.425*10^{23} \ molecules \ FeS[/tex]

50 grams of iron (II) sulfide is approximately 3.425 * 10²³ molecules, not 3.011 *10²³ so the statement is false.

Calculate the molar solubility of aluminum hydroxide (AlOH)3) in a 0.027M solution of aluminum nitrate (Al(NO3)3). The Ksp of AlOH)3 is 2.0x10-32.

Answers

Answer:

s = 5.22x10⁻⁹ M

Explanation:

Let's write the equilibrium reaction for this compound:

Al(OH)₃ <-------> Al³⁺ + 3OH⁻      Ksp = 2x10⁻³²

To get the solubility, we need to write the equilibrium expression:

Ksp = [Al³⁺] [OH⁻]³

Al(OH)₃ does not contribute to the equilibrium expression, because is a solid compound. Now, according to this, we have the following:

                   Al(OH)₃ <-------> Al³⁺ + 3OH⁻

I.                                             0          0

E.                                            s          3s

Replacing into the Ksp expression:

2x10⁻³² = (s) (3s)³

2x10⁻³² = s * 27s³

2x10⁻³² = 27s⁴

s = ⁴√2x10⁻³² / 27

s = 5.22x10⁻⁹ M

This would be the solubility of the compound.

Hope this helps

Formula Reminders

q = mHvap
q = mHfus
1. 4.01 J/gºC
2. 5910 J/g°C
3. 0.387 J/g°C

Answers

Answer: The specific heat capacity of an unknown metal is [tex]0.387 J/g^{o}C[/tex].

Explanation:

Given: Heat energy = 394 J

Mass = 15 g

Initial temperature = [tex]96^{o}C[/tex]

Final temperature = [tex]28^{o}C[/tex]

Formula used is as follows.

[tex]q = m \times C \times (T_{2} - T_{1})[/tex]

where,

q = heat energy

m = mass of substance

C = specific heat capacity

[tex]T_{1}[/tex] = initial temperature

[tex]T_{2}[/tex] = final temperature

Substitute the values into above formula as follows.

[tex]q = m \times C \times (T_{2} - T_{1})\\394 J = 15 g \times C \times (28 - 96)^{o}C\\C = \frac{394 J}{15 g \times (68^{o}C)}\\= \frac{394 J}{1020 g^{o}C}\\= 0.387 J/g^{o}C[/tex]

Thus, we can conclude that the specific heat capacity of an unknown metal is [tex]0.386 J/g^{o}C[/tex].

How is a radioactive element different from a stable element?

Answers

A radioactive element has an unstable nucleus that emits particles in the form of alpha, beta, or gamma radiation. A stable element has a nucleus that does not emit such particles

Radioactive elements are the elements into which an atom is very unstable or highly reactive because it is having more energy in its nucleus. stable elements are those who have stable and there shell are properly filled with electrons.

What are radioactive elements and stable elements?

Most radioactive chemical elements have one or more radioactive isotopes on the other hand  some chemical elements only have one type of radioactive isotopes.

A radioactive element has an unstable nucleus that emits particles in the form of alpha, beta, or gamma radiation and stable element have stable nucleus with no effect of any radiation or energy due to fully filled orbitals.

Bombarding of these radiations has to be done in the nucleus of the element after this the desired element will become a radioactive element. And there is no effect of these rays on stable elements beacuse they are unreactive to this.

The ray of alpha beta and gamma consists of some charges within them and they are radioactive radiations harmful to human eyes.
