Anit [1.1K]4 years ago
6 0

Answer:

Valence electrons.

Explanation:

Hello,

In this case, the electron dot structure is widely known for representing the valence electrons as dots placed around the chemical symbol and they are defined as the electrons configured at the outermost shell of the studied atom. Commonly, electrons are placed up to two on each side of the elemental symbol for a maximum of eight. For instance, sodium has one valence electron, sulfur has six valence electrons, helium has eight valence electrons and so on. Valence electrons are known to be dependent of the electron configuration.

Best regards.

It is possible to make a model of a fission chain reaction with mousetraps and table tennis balls, with the balls placed on an a
konstantin123 [22]

Answer:

The table tennis balls represent neutrons that are released when the nucleus splits and cause other nuclei to split

Explanation:

Nuclear fission is defined as the separation of a nucleus into two smaller nuclei.

It takes a neutron to set off a nuclear fission reaction. When that occurs, neutrons are released and those neutrons in turn are what set off other nuclear fissions. This is defined as a Nuclear Fission Chain Reaction. In the model, the one tennis ball that will be thrown will  be modeled as the starting neutron that sets of the initial (first) fission. The mouse traps with tennis balls represent the other nucleuses waiting to be struck by the one tennis ball. Once the initial tennis ball strikes the first mouse trap, that mouse trap will release its tennis ball hitting others and continuing the cycle.

It can also be modeled as such:

g Green plants use light from the Sun to drive photosynthesis, a chemical reaction in which liquid water and carbon dioxide gas
julsineya [31]

Answer:

0.10 moles of oxygen produced by the reaction of 0.10 of water.

Explanation:

The photosynthesis reaction is given by :

6CO_2(g)+6H_2O(l)\rightarrow C_6H_{12}O_6(aq)+ 6O_2(g)

Moles of water = 0.10 mole

According to reaction, 6 moles of water gives 6 moles of oxygen gas,then 0.10 moles of water will give :

\frac{6}{6}\times 0.10 mol=0.10 mol of oxygen gas

0.10 moles of oxygen produced by the reaction of 0.10 of water.

Which of the following concerning the effects of temperature and pressure on solubility is/are correct?
just olya [345]

Answer:

None of the options are correct.

Explanation:

1) when the temperature of the solution is increased the solubility of the gas in the liquid decreases , hence option 1 is incorrect.

2)The heat released by the dissolution of an ionic compound in water is heat of hydration of the compound and is independent of the initial temperature of the solution.

3) The solubility of a liquid in water is not affected significantly by the pressure changes in the system as gases only have a significant cahne in solubility with change in pressure.
