Answer:

The correct answer is - d. single replacement or displacement.

Explanation:

The displacement or replacement reaction is the reaction in which the less reactive molecule or element is replaced by the more reactive element or molecule in the reaction. If there is only one replacement occurs its termed as a replacement or single replacement reaction.

In this case, if chlorine gas passes through the water solution of KI (potassium iodide), solid iodine and KCl are produced by the displacement or replacement reaction. Here iodine is less reactive so replaced by the more reactive chlorine.

2KI(aq)+Cl2 (g)→2KCl(aq)+I2 (s)

What were the defects in Ruther Ford Atomic model?

juin [17]

the RutherFord atomic model has the limitations in explaining the stability of the atom and the stability of the electron.

Explanation:

As we know basically the atom comprises of the positively charged proton and negative charge electron and no charge neutron.
In these particles, electron revolves with the nucleus as a centre in the orbit with the different energy levels.
So by this revolving action, there will be the loss of energy and thus electrons are to be falling into the nucleus which affects the stability of the electron.
The atom is said to be neutral electrically if the protons and electrons are equal. So in the above case if the electrons on losing the energy if it fells into the nucleus, as a result, the stability of the atom is affected which makes the atom as ions.

How does the sun cause wind

Juli2301 [7.4K]

Well, the sun heats up colder areas, the temperature difference causes wind. (sorry if wrong)

Answer:

1. Cells contain DNA that is passed cell to cell during cell divison.

2. Cells are similiar in chemical composition and reactions that maintin homeostasis.

3. All basic chemical and physiological functions are carried out inside the cell.

Given the following information regarding the masses and relative abundances for the isotopes of an element, determine its atomi

Ilia_Sergeevich [38]

Answer:

Average atomic mass = 58.51047 amu

The symbol is $Ni$

Explanation:

The formula for the calculation of the average atomic mass is:

$Average\ atomic\ mass=(\frac {\%\ of\ the\ first\ isotope}{100}\times {Mass\ of\ the\ first\ isotope})+(\frac {\%\ of\ the\ second\ isotope}{100}\times {Mass\ of\ the\ second\ isotope})+(\frac {\%\ of\ the\ third\ isotope}{100}\times {Mass\ of\ the\ third\ isotope})+(\frac {\%\ of\ the\ fourth\ isotope}{100}\times {Mass\ of\ the\ fourth\ isotope})+(\frac {\%\ of\ the\ fifth\ isotope}{100}\times {Mass\ of\ the\ fifth\ isotope})$

Given that:

For first isotope:

% = 68.274 %

Mass = 57.9353 amu

For second isotope:

% = 26.095 %

Mass = 58.9332 amu

For third isotope:

% = 1.134 %

Mass = 61.9283 amu

For fourth isotope:

% = 3.593 %

Mass = 63.9280 amu

For fifth isotope:

% = 0.904 %

Mass = 63.9280 amu

Thus,

$Average\ atomic\ mass=\frac{68.274}{100}\times {57.9353}+\frac{26.095}{100}\times {58.9332}+\frac{1.134}{100}\times {61.9283}+\frac{3.593}{100}\times {63.9280}+\frac{0.904}{100}\times {63.9280}$

$Average\ atomic\ mass=39.55474 +15.37861854+0.702266922+2.29693304+0.57790912$

Average atomic mass = 58.51047 amu

The symbol is $Ni$
