Answer:

d . H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O

Explanation:

The given reactions are:

a . 2HgO → 2Hg + O₂,

It is a decomposition reaction, that HgO is decomposed to give Hg and O.

b . Na₂SO₄ + BaCl₂ → BaSO₄ + 2NaCl,

It is a double replacement reaction where two salts replaces their cations and anions with each others producing 2 new salts.

c . Zn + 2AgNO₃ → Zn(NO₃)₂ + 2Ag,

It is a single replacement reaction, that Zn replaces Ag from its salt.

d . H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O

It is acid-base reaction "neutralization reaction" where H₂SO₄ (acid) reacts with KOH (base) producing K₂SO₄ (salt) and water.

So, the right choice is:

d . H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O

An advantage of reproduction is that a genetic disorder in a parent might not affect the offspring.

Elan Coil [88]

The advantage of sexual reproduction is that the offspring might not get the genetic disease carried by one of the parents since a mixture of two genetics are involved in the production of offspring that shares half of each’s genetics it can be possible that genetic diseases might be skipped in the offspring.

Unlike sexual reproduction asexual reproduction has chances of genetic caring of diseases because the genes carry genetic information completely from the parent gene.

Na-23 has 12 neutrons. What is it’s atomic number?

quester [9]

Answer:

Explanation:

Data obtained from the question include:

Mass number = 23

Neutron = 12

Atomic number =.?

Next, we shall determine the number of protons present in the element.

This can be achieved by doing the following:

Mass number = Proton + Neutron

Mass number = 23

Neutron = 12

Proton =...?

Mass number = Proton + Neutron

23 = Proton + 12

Collect like terms

Proton = 23 – 12

Proton = 11

The atomic number of an element is equal to the proton number.

Atomic number = proton number

Proton number = 11

Atomic number = proton = 11

Therefore, the atomic number is 11.

Classify which compounds will dissolve in water and which ones will not dissolve in water.

vredina [299]

Answer:

Dissolves in water: Acetone, 1-propanol, Methanol

Do not dissolve in water: Hexane, Decane

Explanation:

From the principle that like dissolves like,polar substances will dissolve in polar solutions, while non-polar substances will dissolve in non-polar substances.

Water is a polar solution, therefore, polar substances will dissolve in it.From the given options:

Acetone is a polar molecule, therefore, it will dissolve in water.

1-propanol is a polar molecule, therefore, it will dissolve in water.

Hexane is a non-polar molecule, therefore, it will not dissolve in water.

Methanol is a polar molecule, therefore, it will dissolve in water.

Decane is a non-polar molecule, therefore, it will not dissolve in water
