Answers

Answer 1

Answer:

Answer : Option D) Proton and Neutron.

Explanation : The part of the atom that carries a positive charge is the proton, and the part that carries a neutral charge is the neutron.

A proton is a small subatomic particle, denoted by symbol $p or p^(⁺)$ , with a positive electric charge of +1 e elementary charge and a mass which is slightly less than that of a neutron. It is located at the center o atomic nucleus along with neutron. The number of protons are equal to the number of electrons of that atom but are in opposite charges.

A neutron is a subatomic particle of an atom which is of the same mass as that of proton but without an electric charge, it is present in all atomic nuclei except those of ordinary hydrogen. It is also located at the center of an atomic nucleus.

Answer 2

Answer: Proton; neutron
Protons have a positive charge
Neutrons are neutral
Electrons have a negative charge :)

Why would an electrician use parallel circuits to wire the lights in each room of a house instead of using a series circuit?A. When electricians get their license, they are only licensed to install parallel circuits. Most electricians aren't certified to install series circuits. B. Parallel circuits prevent electrons from flowing if part of the circuit is broken and therefore prevent fires. Series circuits cause more fires because electrons still flow. C. Electrons continue to flow in a parallel circuit even if part of the circuit is broken. In a series circuit, a break such as a burned out lightbulb would cause the current to stop in the whole room. D. Parallel circuits are much easier to wire and are required by the electrical code for housing construction in most communities. Series circuits are sometimes used with special approval.

Select all that apply. Which statements correspond to cellular respiration? O 2 is pumped in and forces CO 2 out. CO 2 diffuses passively out of the cell. CO 2 must be pumped out of the cell. CO 2 diffuses passively into the cell. O 2 diffuses passively when converted to CO 2. O 2 diffuses passively when produced inside the cell.

Answers

Answer:

The correct answer is CO2 diffuses passively out of the cell.

Explanation:

Carbon dioxide is one of the end product of cellular metabolism.CO2 is produced as waste material inside the body after cellular respiration.

Carbon dioxide is transported out from the body by passive diffusion process which helps the CO2 gas to move along the concentration gradient from high concentration region(body) to the low concentration region(atmosphere).

Thus CO2 ia being eliminated from our body.

Which barium salt is insoluble in water?A) BaCO3. B) BaCl2
C) Ba(ClO4)2. D) Ba(NO3)2

Answers

$\boxed{{\text{A) BaC}}{{\text{O}}_{\text{3}}}}$ is insoluble in water.

Further Explanation:

Solubility rules

These help in predicting whether the given compound is soluble or insoluble in nature. Some of the solubility rules are as follows:

1. Group 1A compounds are soluble in nature.

2. All the common compounds of ammonium ion and all acetates, chlorides, nitrates, bromides, iodides, and perchlorates are soluble in nature. But the ions whose chlorides, bromides, and iodides are not soluble are ${\text{A}}{{\text{g}}^ + }$ , ${\text{P}}{{\text{b}}^(2 + )}$ , ${\text{C}}{{\text{u}}^ + }$ and ${\text{Hg}}_2^(2 + )$ .

3. All common fluorides, except for ${\text{Pb}}{{\text{F}}_{\text{2}}}$ and group 2A fluorides are soluble. Also, all sulfates except ${\text{CaS}}{{\text{O}}_{\text{4}}}$ , ${\text{SrS}}{{\text{O}}_{\text{4}}}$ , ${\text{BaS}}{{\text{O}}_{\text{4}}}$ , ${\text{A}}{{\text{g}}_{\text{2}}}{\text{S}}{{\text{O}}_{\text{4}}}$ and ${\text{PbS}}{{\text{O}}_{\text{4}}}$ are soluble.

4. All common metal hydroxides except ${\text{Ca}}{\left( {{\text{OH}}} \right)_{\text{2}}}$ , ${\text{Sr}}{\left( {{\text{OH}}} \right)_{\text{2}}}$ , ${\text{Ba}}{\left( {{\text{OH}}} \right)_{\text{2}}}$ and hydroxides of group 1A and that of transition metals are insoluble in nature.

5. All carbonates are insoluble in nature, except for sodium, potassium and ammonium.

6. Salts having ions like $\text{Cl}^-$ , $\text{Br}^-$ or $\text{I}^-$ are generally soluble except those of $\text{Ag}^+$ , $\text{Pb}^(2+)$ and ${\left( {{\text{H}}{{\text{g}}_2}} \right)^{{\text{2 + }}}}$ .

7. Group 1A and group 2A perchlorates are soluble in nature.

8. All sulfates of metals are soluble, except for lead, mercury (I), barium, and calcium sulfates.

9. The salts having nitrate ions are soluble in nature.

According to the solubility rules, only carbonates of sodium, potassium and ammonium are soluble in nature. So barium carbonate $\left( {{\text{BaC}}{{\text{O}}_{\text{3}}}} \right)$ is insoluble in nature. But chlorides, nitrates and perchlorates of barium are soluble in water. Therefore option A is the correct answer.

Subject: Chemistry

Keywords: barium, water, insoluble, solubility rules, soluble, insoluble, water, BaCO3.

BaCO₃ is generally considered insoluble in water. Carbonates are often insoluble, except for some alkali metals and ammonium carbonates. Therefore, option A is correct.

The solubility of salt depends on its nature and the interactions between its ions and water molecules. In this case, determine the solubility of each salt by considering the common solubility rules.

BaCl₂ is soluble in water. Chlorides (Cl-) are mostly soluble except for a few exceptions, such as silver chloride, lead chloride, and mercury(I) chloride.

Ba(ClO₄)₂ is soluble in water. Perchlorates (ClO4-) are typically soluble.

Ba(NO₃)₂ is soluble in water. Nitrates (NO3-) are mostly soluble.

Based on the solubility rules, the salt that is insoluble in water is BaCO₃ (barium carbonate).

Hello,How can you tell if a molecular ion will have one or ore unpaired eletrons?

For example,
"Which of the following molecules is expected to have one or more unpaired electrons? Check all that apply.

O2-
F2+
N22-
O22-"
Any help would be appreciated. ...?

Answers

I believe the correct answers from the choices listed above are the first two options. The molecules O2- and F2+ are expected to have one unpaired electron. This can be determined by looking at the value of the charge. Hope this answers the question.

Final answer:

To determine unpaired electrons, look at the valence electrons in an ion's molecule, accounting for extra or absent electrons due to the ion's charge. For instance, O2- and F2+ have one unpaired electron, but N22- is not a valid ion, and O22- electrons are all paired.

Explanation:

To determine if a molecular ion will have one or more unpaired electrons, we need to look at the number of valence electrons in the molecule and take into account any extra or absent electrons due to the charge of the ion.

For example, O2- has 12 + 1 = 13 valence electrons (6 from each oxygen atom and 1 extra due to the negative charge). It requires 14 for all the electrons to be paired (2 in each oxygen's inner shell and 4 bonds or lone pairs in the outer shell), thus there is one unpaired electron in O2-.

However, in F2+, there are only 13 electrons because one electron is lost due to the positive charge. Like oxygen, fluorine also prefers to have 7 electrons in its outer shell, so there are also unpaired electrons in F2+.

N22- doesn’t exist because nitrogen normally forms triple bond and doesn’t need or want to take extra electrons, so this molecular ion is not valid.

O22- has 14 + 2 = 16 valence electrons and this total number of valence electrons is an even number, which indicates all the electrons are paired.

Answers

These feature that was formed by hotspot volcanism is The Big Island of Hawaii. The Hawaiian Islands are actually found at the tip of several volcanoes that has been formed by a series of volcanic eruptions. Today, the Big Island sits on the hotspot, and contains the only active volcanoes of the group of islands.

The Big Island of Hawaii was formed by hotspot volcanism, whereas The Grand Canyon, The Appalachian Mountains, and The Himalaya Mountain Range were not.
