what is the nature of ions formed by different atoms.

Answers

Answer 1

The nature of ions formed by different atoms is as follows:

Metal atoms form positively-charged ionsNon-metal atoms form negatively-charged ions

What are ions?

Ions are substances which are formed when neutral atoms gain or lose electrons.

There are two types of ions based on the charge the ion carries;

anions - which are negatively-chargedcations - which are positively-charged

The nature of the ions formed by different atoms depend on whether the atoms are atoms of metals or atoms of non-metals.

Metal atoms form positively-charged ions by the loss of one or more electrons as illustrated below:

M → M⁺ + e⁻

where; M is a metal atom, M⁺ is a metal ion, and e⁻ is an electron.

Non-metal atoms form negatively-charged ions by the gain of one or more electrons as illustrated below:

N + e⁻ → N⁻

where; N is a non-metal atom, N⁻ is a non-metal ion, and e⁻ is an electron.

In conclusion, the nature of ions formed by atoms depends on the nature of the atom, whether they are metallic or non-metallic atoms.

If 6.0 L of CO reacts at STP, how many liters of oxygen are required for the reaction?

Answers

Answer:

3.0 L O₂

Explanation:

If CO reacts at STP, it means that there are 1.0 moles of CO. To find the moles of O₂, you need to use the mole-to-mole ratio from the given equation.

1.0 moles CO            1 mole O₂
----------------------  x  ---------------------  =  0.5 moles O₂
                                2 moles CO

To calculate the liters of oxygen, you need to use Avogadro's Law:

V₁ / N₁ = V₂ / N₂

In this equation, "V₁" and "N₁" represent the volume and moles of the first molecule. "V₂" and "N₂" represent the volume and moles of the second molecule. You can plug the given and calculated values into the equation and simplify to isolate V₂.

V₁ = 6.0 L                     V₂ = ? L

N₁ = 1.0 moles              N₂ = 0.5 moles

V₁ / N₁ = V₂ / N₂                                            <----- Avogadro's Law

(6.0 L) / (1.0 moles) = V₂ / (0.5 moles)         <----- Insert values

6.0 = V₂ / (0.5 moles)                                   <----- Simplify left side

3.0 = V₂                                                         <----- Multiply both sides by 0.5

Answers

When 3. 41 g of C6H12O6 is dissolved in 85 ml of water the molality is 2.2m.

What is molality?

Molality is the amount of a substance dissolved in a certain mass of solvent.

Molality = moles of solute/ mass of solvent (kg)

Given,

Mass of solute = 3.14g

Molar mass of solute = 180 g

Mole of solute= given mass/molar mass

= 3.14/180

= 0.0189 mol.

Volume of solvent = 85 ml

Density of water = 1 g/cm3

Density = mass/ volume

mass = density × volume

= 1× 85

= 85g

Molality = (0.0189/ 85) × 1000

= 2.2m

Write the empirical formula for at least four ionic compounds that could be formed from the following ions:

Answers

Answer:

Fe(C₂H₃O₂)₃,  Fe(CN)₃,  Pb(C₂H₃O₂)₄,  Pb(CN)₄

Explanation:

Cations (positively charged ions) can only form ionic bonds with anions (negatively charged ions). However, you can't just simply put one cation and one anion together to form a compound. Each compound needs to been neutral, or have an overall charge of 0. When cations and anions do not have charges that perfectly cancel, you need to modify the amount of each ion in the compound.

1.) Fe(C₂HO₂)

2.) Fe(CN)

Explain why when an ion is formed, the mass of the atom does not change.

Answers

Answer:

Atoms are made up of protons, neutrons, and electrons. The mass of an atom is determined by the total number of neutrons and protons in the nucleus. The difference between an atom and an ion is the number of electrons. The change of electrons does not change the mass because electrons have a negligible mass. In other words, the mass of electrons is so small, it is considered insignificant.

How many grams of agcl would be needed to make a 4. 0 m solution with a volume of 0. 75 l?

Answers

430 g of AgCl would be needed to make a 4.0m solution with a volume of 0.75 L.

What is Molarity?The amount of a substance in a specific volume of solution is known as its molarity (M). The number of moles of a solute per liter of a solution is known as molarity.Calculation of Required amount of AgCl

Remember that mol/L is the unit of molarity (M).

We can compute the necessary number of moles of solute by multiplying the concentration by the liters of solution, according to dimensional analysis.

0.75L×4.0M=3.0mol

Then, using the periodic table's molar mass for AgCl, convert from moles to grams:

3.0mol×143.321gmol=429.963g

The final step is to round to the correct significant figure, which in this case is two: 430g.

Answers

A 1. 7 m solution of the acid ha has a ph of 1. 0, then the ka of the acid is 6.25×10^(-3).

What is acid dissociation constant?

The acid dissociation constant is defined as the value which is used to measure the strength of the specific acid in the solution.

Equation for general dissociation of strong or weak acid is

HA ----- (H+) + ( A-)

Ka can be expressed as

Ka = [H+] [A-]/[HA]

where [H+] is the concentration of H+ ions

Now, we will find the value of concentration of H+ ions

pH = -log [H+]

1 = -log[H+]

[H+] = antilog(-1)

[H+] = 0.1

By using ICE table, we find that the concentration of [HA] is

1.7-0.1

= 1.6

By substituting all the values we get,

Ka = 0.1 × 0.1/1.6

= 6.25×10^(-3)

Thus, we find that the Ka value of the given solution is 6.25×10^(-3).

The dissociation reaction for ammonia is given as,

NH₃ (aq) + H₂O (l)  ⇄  NH₄⁺ (aq) + OH⁻ (aq)

Here, the concentration of ammonia is [NH₃] - x, ammonium ion is [NH₄⁺] + x, and hydroxide ion is x.

The molar concentration of ammonia is,

M = (0.12 M × 0.2 L) ÷ 0.45 L = 0.053 M

The molar concentration of ammonium ion is,

M = (0.15 M × 0.25 L) ÷ 0.45 L = 0.083 M

From the base dissociation constant and previous concentration from the reaction, the value of x or hydroxide ion is calculated as,

Kb = [NH₄⁺][OH⁻] ÷ [NH₃]

1.8 × 10⁻⁵ (0.053 - x) - (0.083 + x) × x = 0

x = [OH⁻] = 1.15 x 10⁻⁵

The pH from the hydroxide ion is calculated as,

pOH = - log [OH⁻]

= - log (1.15 x 10⁻⁵)

moles = 0.03 mole

Volume of the aqueous solution of sodium sulfate

Concentration = moles/volume in liters

0.195 = 0.03/V

V = 0.03/0.195

V = 0.15385 liters

V = 153.85 mL

Thus, the volume of the aqueous solution of sodium sulfate required is 153.85 mL.

A 400. 0 g sample of liquid water is at 30. 0 ºc. how many joules of energy are required to raise the temperature of the water to 45. 0 ºc?

Answers

Energy required to raise the temperature from 35°C - 45 °C= 25116 J.

specific heat, the quantity of warmth required to raise the temperature of one gram of a substance by means of one Celsius degree. The units of precise warmth are generally energy or joules consistent with gram according to Celsius diploma. for instance, the unique warmth of water is 1 calorie (or 4.186 joules) according to gram in step with Celsius degree.

solving,

Sample of liquid = 400. 0 g

temperature = 30. 0 ºc

joules of energy are required to raise the temperature of the water to 45. 0 ºc

therefore rise in temperature 45 - 30 = 15°C

Specific heat capacity = 4.186 J/g m °C

In kelvin = 273 + 15 = 288

          = ∴ energy required = Q = m s ( t final - t initial)

            =  400*4.186 * 15

           = 25116 joule

What is the kinetic product obtained from the addition of 1 mole of bromine to 1,3-butadiene?

Answers

From the addition of 1 equivalent of HBr to 1,3-butadiene, 3-bromo-1-butene is obtained as a product.

What is moles?

Moles are defined as the smallest base unit that is equivalent to [tex]6.02214 X 10^{23}[/tex] units.

Moles are chemical entities, which are used to measure the mass or molecular mass of the compound, molecule, or atom. The moles are, for example can be explained as equal to the mass of the atom. For example, there is one mole in 12 grams of carboncarbon.

Thus the kinetic product formed is 3-bromo-1-butene.
