Answer:

It is an unstable atom

It would have neutral charge

It would have 8 neutrons

Explanation:

Answer:

1 mol Be

Explanation:

First look at periodic table. Be (Beryllium) has an atomic mass of 9.012

1 mole of Be atoms = 9.012 g Be (this is your conversion factor)

Start with what you are given: 9.01 b Be. Then look at the periodic table. Be has an atomic weight of 9.012g. In order to cancel out the g place how you see here, cross out the g and your are left with mole Be on top. divide 9.01 by 9.012 to get .99977807. round that to 1 mol Be

[tex](\frac{9.01 g Be}{1} )(\frac{1moleBe}{9.012 gBe} )=.99977807 moleBe[/tex]

Answer:

This question is incomplete, the options to this question are:

(A)A gas station and people playing hopscotch

(B)A squirrel eating acorns and a fire burning

(C)Someone reading a book and eating a sandwich

(D)Someone sliding down the slide and someone drinking water

The answer is B

Explanation:

Energy, which cannot be created nor destroyed according to the law of conservation of energy, exists in different forms. These forms of energy are, however, interconvertible. According to this question, Henry is in the community investigating sources of chemical energy for his science experiment.

Chemical energy is one of the forms of energy produced or used up during chemical reactions. Based on the options provided, the best examples of chemical energy Henry can use is "A squirrel eating acorns and a fire burning".

- A squirrel eating acorns is a source of chemical energy Henry can use because chemical energy are stored in the bonds of the food molecule (acorns).

- A fire burning is another source of chemical energy because burning is a chemical process.

Answer:

it means plasmid dna

Explanation:

The naked DNA is a free DNA without surrounded by any protein or lipid layer. Also, The naked DNA is called plasmid DNA

i have advanced so i got this right

Answer: Naked DNA refers to DNA that is not associated with lipids, proteins, or any other molecule to help protect it. Naked DNA is the result of release of genetic material into the surrounding environment, such as from bursting cells. Incoming DNA is often incorporated into the bacterial genome after absorption.

Answer:

C ;Both have one valence electron.

Explanation:

Elements classified to be in the same group in the periodic table possess the same number of valence electrons. This means that they will react the same way with other elements as they require the same number of electrons to fill their electron shell.

This is the case of sodium (Na) and potassium (K) which both belongs to group 1. This means that they have one valence electron in their outermost shell. Hence, this accounts for the reason they both will behave chemically similar to one another.

Answer:

Conductivity, Malleability, High Melting Point, Luster

Explanation:

Transition metals have the following properties:

Conductivity (Electrical and Thermal)

Malleability (You can hit it with a hammer to mold it)

High melting point

Luster (Shininess)

Answer:

10 atoms of hydrogen

Explanation:

The atom of an element refers to the smallest indivisible substance of that element that retains its chemical properties. The atoms of an element combine to form a molecule, which then combines with atoms of other elements to form a compound.

In this case, CH3(CH2)2CH3 is a given organic compound. The number of hydrogen atoms can be determined thus:

H represents one hydrogen atom

- We have H3 - 3 atoms

- We have (H2)2 - 4 atoms

- We have H3 - 3 atoms

Altogether, this gives a total of 10 hydrogen atoms in the CH3(CH2)2CH3 compound.

Answer:

Liquid nitrogen, on the other hand, boils at a much colder temperature. Liquid nitrogen boils at -320 degrees. That means that as soon as LN2 leaves our special holders and hits the air, it instantly vaporizes because the air around it is so cold.

is your answer for the question

Answer:

they are located on the abbism

Answer:

The kinetic molecular theory can be used. Temperature is increased, so the average kinetic energy and the rms speed should also increase. This means that the gas molecules will hit the container walls more frequently and with greater force because they are all moving faster.

Explanation:

Answer:

See the answer below

Explanation:

A neutralization reaction is a reaction that involves acid and base with the production of salt and water as the end products. An example is as below:

HCl + NaOH --> NaCl + H2O

The salt produced here is NaCl. In solution, NaCl will ionize as:

[tex]NaCl --> Na^+ + Cl^-[/tex]

Hence, the salt's positive ion (Na+) was contributed by the base (NaOH) while its negative ion (Cl-) was contributed by the acid (HCl).

Answer:

The answer is 4

Explanation:

Carbon has four valence electrons and here a valence of four. Each hydrogen atom has one valence electron and is univalent

Answer:

there are 4 valence electrons, they are the ones on the outmost ring :)

Explanation:

sorry i typed it in the wrong place

Answer:

Most of us use the word 'heat' to mean something that feels warm, but science defines heat as the flow of energy from a warm object to a cooler object. ... Heat energy is the result of the movement of tiny particles called atoms, molecules or ions in solids, liquids and gases

Answer:

Yes, gold can be created from other elements. But the process requires nuclear reactions, and is so expensive that you currently cannot make money by selling the gold that you create from other elements. ...

Explanation:

Answer:true

I hope this helped! if you need explanation just ask.

Answer:

A pure substance consists only of one element or one compound, whereas a mixture consists of two or more different substances, not chemically joined together.

Answer:

The metalloids are a unique group of elements that share properties of both metals and nonmetals. They're also called the semimetals because of the shared properties of these elements along the dividing line between metals and nonmetals.

Elements: Arsenic

Explanation:

brainlist pls thx

Answer: A

Explanation: Hydrogen bonds compare with other intermolecular forces because of that fact that they are stronger than other Van Der Waals forces. So, the answer to the question should be A.

Hope this helps!

Answer: it's A

Explanation: finished the quiz

Answer:

water and oxygen

Explanation:

only iron and iron alloys can rust whereas other elements corrode. for rusting to happen, 2 substances need to be present: water and oxygen

Answer:

Metal[Iron]+Water+air[Oxygen]-->Rusting

Explanation:

Rusting is an oxidation reaction.The iron reacts with oxygen and water to form hydrated iron[III]oxide.which is seen as rust due to the change in color [to brown]

Answer:

A systems model is a process-oriented representation that emphasizes influences, or flow, of information between modules. A systems model describes how processes interact and what operations these processes perform, but it does not go into details as to how these processes are implemented.

Answer:

CO2+H20 for the first question, AlCl3 + Ag for the second or C and B

Explanation:

I am looking at it right now on Edge

c) CO₂ + H₂O

C₃H₈+O₂→ CO₂ + H₂O

Explanation:

Firstly we need to know about combustion, it is a chemical process which involves the reaction of a substance with oxygen.

The chemical reaction given below represents the combustion of propane which yields to the production of carbon dioxide and water molecule.

C₃H₈+O₂→ CO₂ + H₂O

The balanced chemical reaction is represented below:

C₃H₈ +5O₂ → 3CO₂ + 4H₂O
