Will a precipitate form when 100mL of 4.0x10^-4M Mg(NO3)2 is added to 100mL of 2.0x10^-4M NaOH? (Ksp Mg(OH)2= 1.5 x 10^-11)
200 mL of .004M BaCl2 are mixed with 600 mL of .008M K2SO4. will a precipitate form? (Ksp (BaSO4)= 1.1x10^-10)

Answers

Answer 1

Yes, Mg(OH)₂ will precipitates if ion product > Ksp.

Yes, BaSO₄ will precipitates if ion product > Ksp.

How to predict Mg(OH)₂ precipitation?

To determine whether a precipitate will form when Mg(NO₃)₂ is added to NaOH, we need to compare the ion product (Qsp) of Mg(OH)₂ to its solubility product (Ksp). If Qsp is greater than Ksp, then a precipitate will form.

Calculating Qsp for Mg(OH)₂:

Mg(NO₃)₂ → Mg₂+ + 2NO₃-

NaOH → Na+ + OH-

Mg₂+ + 2OH- → Mg(OH)₂

[Mg₂+] = 4.0x10⁻⁴ M

[OH-] = 2.0x10⁻⁴ M

Qsp = [Mg₂+][OH-]² = 4.0x10⁻⁴ x (2.0x10⁻⁴)² = 1.6x10⁻¹¹

Since Qsp is less than Ksp, which is 1.5 x 10⁻¹¹, a precipitate will not form.

How to predict BaSO₄ precipitation?

To determine whether a precipitate will form when BaCl₂ is mixed with K₂SO₄, we need to compare the ion product (Qsp) of BaSO₄ to its solubility product (Ksp). If Qsp is greater than Ksp, then a precipitate will form.

Calculating Qsp for BaSO₄:

BaCl₂ → Ba₂+ + 2Cl-

K₂SO₄ → 2K+ + SO42-

Ba₂+ + SO42- → BaSO₄

[Ba₂+] = 0.004 M

[SO42-] = 0.008 M

Qsp = [Ba₂+][SO42-] = 0.004 x 0.008 = 3.2x10⁻⁵

Since Qsp is greater than Ksp, which is 1.1x10⁻¹⁰, a precipitate will form.

howany grams of carbon dioxide CO2 is produced when 3.5 moles of octane C8H18 is burned ?

Answers

Answer:

1232 g of carbon dioxide are formed

Explanation:

As octane is being burned it would be combustion reaction.

writing the balanced equation:

C8H18 + 25/2 O2 →  9 H2O + 8 CO2

now stepping up mole ratio from the balanced equation:

                   moles of octane    :      moles of carbon dioxide

                               1                  :                    8

                                3.5             :                    X

X = 3.5 x 8 = 28

therefore when 3.5 moles of octane are burned in air 28 moles of carbon dioxide are evolved.

now in order to calculate the mass of CO2 formed

molar mass of CO2 = 12 + (16 x 2) = 44g

now calculating the mass of 28 moles:

                          moles : mass

                              1      : 44 g

                              28  :   X

X = 28 x 44 = 1232 g

1232 g of CO2 are formed

Answers

The size of the human population is affected by several factors, including age structure, survivorship rate, fertility, and migration.

Age structure refers to the distribution of individuals in a population by age. A population with a large proportion of young individuals is likely to have higher fertility rates and a higher potential for population growth. A population with a large proportion of older individuals is likely to have lower fertility rates and a lower potential for population growth.

Survivorship rate refers to the likelihood of an individual surviving to a certain age. A population with a high survivorship rate is likely to have a larger population overall, as more individuals are living to reproductive age.

What is the human population  about?

Fertility rate refers to the number of children born to women of childbearing age. A population with a high fertility rate is likely to have a higher potential for population growth.

Migration refers to the movement of individuals into or out of a population. A population with high levels of immigration is likely to have a higher potential for population growth, while a population with high levels of emigration is likely to have a lower potential for population growth.

Therefore, It is difficult to predict the size of the human population with certainty, as it depends on many complex factors and can be affected by unexpected events.

The temperature at which a substance transforms from a solid into a liquid is known as its melting point. The temperature at which a substance transforms from a solid into a liquid is known as its melting point. The balance between the solid and liquid phases is reached at the melting point. Pressure affects a substance's melting point, which is often reported at a standard pressure of 1 atmosphere, or 100 kPa. The melting point is the fixed temperature at which a solid transforms into a liquid. For instance, at 0°C, ice cubes begin to melt and turn from a solid to a liquid.

How do you find melting point?

By placing a small amount of an organic solid in a tiny capillary tube, affixing it to the stem of a thermometer centred in a heating bath, and gradually heating the bath, one may calculate the temperature at which melting begins and finishes. Melting points are frequently used to describe and rate the purity of organic and inorganic crystalline substances.

Answers

The grams of ammonia (NH₃) can be produced from the reaction of 28 grams of nitrogen gas with an excess of hydrogen gas is 34 g.

The reaction is given as :

3H₂  +   N₂  ---->  2NH₃

The mass of the Nitrogen gas = 28 g

Moles of the  N₂  = mass / molar mass

                            = 28 / 28 g/mol

                            = 1 mol

The 1 mole of the  N₂ produces the 2 moles of the NH₃

Therefore , the moles of the NH₃ = 1 × 2
