What is Rutherford atomic modle

Answers

Answer 1

Answer:

Answer:

Rutherford's atomic model explained how the electrons surrounded the nucleus of protons and neutrons. His model showed how J. J. Thomson's Plum Pudding model was incorrect.

Answer 2

Answer:

Answer:Rutherford model of an atom shows that an atom is mostly an empty space,with electrons orbiting a fixed positively charged nucleus in set.

How many total valence electrons take part in a triple bond between 2 atoms?

Answers

6, to do a single bond you need two singular valence electrons to create one bond. Therefore to create a triple bond you need 6 singular valance electrons.

For metalloids on the periodic table, how do the group number and the period number relate? A. The lower the group number, the lower the period numbers, so the metalloids are found in a diagonal moving down from left to right.
B.The lower the group number, the higher the period numbers, so the metalloids are found in a diagonal moving up from left to right.
C.The higher the group number, the lower the period numbers, so the metalloids are found in a diagonal moving down from left to right.
D.The higher the group number, the higher the period numbers, so the metalloids are found in a diagonal moving up from left to right.

Answers

Answer : The correct option is A.

Explanation :

Metalloid : Metaloids are the elements whose properties lie between the metals and non-metals.

There are six commonly elements which are boron, silicon, germanium, arsenic, antimony and tellurium. The rare elements are polonium and astatine.

The relation between the group number and period number of metalloid is that the lower the group number, the lower the period numbers and the metalloids are found in a diagonal moving down from left to right in the periodic table.

Answer:

(A) The lower the group number, the lower the period numbers, so the metalloids are found in a diagonal moving down from left to right.

Explanation:

write a balanced chemical equation for the reaction of zncl2 with excess NaOH to produce Na2Zn(oh)4 sodium zincate. what mass of sodium zincate can be produced from 2.00 g of ZNCl2 with excess Naoh by this reaction?

Answers

$4NaOH _((aq)) + ZnCl_(2)_((aq)) ----\ \textgreater \ Na_(2)Zn(OH)_(4)_((ppt)) + 2NaCl (aq)$

$mol = (mass)/(molar mass)$
∴ $mol of ZnCl_(2) = (2.00 g)/([(65)+(35.5 * 2)g/mol)$
= $(2.00 g)/(136 g/mol)$
= 0.0147 mol

$Moles of Na_(2)Zn(OH)_(4) :$
$ratio of ZnCl_(2) : Na_(2)Zn(OH)_(4)$
1 : 1
∴ $Moles of Na_(2)Zn(OH)_(4) <span>$ = 0.0147 mol

Mass = Molar Mass * Mol
∴ $Mass of Na_(2)Zn(OH)_(4) <span>$ = [(23 * 2)+(65)+(16 * 4) + (1*4)] g/mol * 0.0147 mol
= 179 g/mol * 0.0147 mol
= 2.63 g

Nonrenewable energy sources _____.can be quickly replenished
are easily recycled
can eventually be used up
never cause pollution

Answers

Non-renewable energy sources CAN EVENTUALLY BE USED UP.

Non renewable energy sources refer to those energy sources that can not be replenished. Once they are used up, new one can not be formed or produced, this is because they can only be formed by natural processes and these processes take millions of years to occur. Examples of non renewable energy sources are: coal, natural gas and oil. All the fuels obtained from fossils are non renewable in nature.

Answer:

The correct answer is option C, can eventually be used up

Explanation:

Nonrenewable energy sources are those resources which if once used cannot be re used again.

For example – Coal, petroleum(petrol & diesel), fossils, natural gas etc.

These resources cannot be replenished if once they are consumed as they take millions of year to form.

Also all these resources are made up of hydrocarbons thus they produce polluting gases on burning except natural gas.

How did Moseley establish a more accurate periodic table?

During the 1960s and 1970s, Cesar Chavezworked to unionize migrant farm workers by
(1) seizing the land of the lettuce and grape
growers
(2) securing passage of federal legislation to limit
immigration
(3) using nonviolent tactics such as boycotts and
hunger strikes
(4) urging growers to reduce the workforce
through mechanization

Answers

Answer:

The correct answer is option (3) "using nonviolent tactics such as boycotts and hunger strikes".

Explanation:

Cesar Chavez was a leader of American labor and civil right activists that fought to unionized migrant farm workers by the creation of The National Farm Workers Association. Cesar Chaves used nonviolent tactics to support the migrant farm workers. For instance, when Filipino American farm workers protested for higher wages in 1965, he encouraged Americans to boycott table grapes to support them; while he once performed a 24-day hunger strike in 1972 in the Santa Rita Center as a response to Arizona prohibiting boycotts and strikes by farm workers.
