Element with the largest electron cloud

AnswereYs

Explanatioynt:Yes

Answer:

When you make the electronegativities of A(Positive partial charge) and C (Negative Partial charge) less and have B with a strong electronegativity to create a very strong molecular dipole. ... Both molecules possess strong molecular dipoles.

Answer:

The shape of a molecule is mostly determined by repulsion among the pairs of electrons around a central atom.

Answer:

The reactants of cellular respiration are oxygen and sugar, which are the products of photosynthesis

Explanation:

Answer:

Delocalized electrons

Explanation:

Magnesium Chloride is an ionic compound, so its lattice structure prevents the flow of electrons. However, when you convert the ionic compound into an aqueous solution it allows movement of electrons/ions due to the breakdown of the molecular forces which make it conductible. In short, Ionic compounds as a solid are not conductible but they are in an aqueous form.

Answer:

Oxegen

Explanation:

All that oxygen has to come from somewhere. You might already know that it comes from photosynthetic organisms like plants.

Based on the balanced equation, the mole ratio of Iron to Sulphur is 8 to 1.

This means that for every mole of sulfur, 8 moles of iron is needed for the reaction.

∴ since the moles of Sulfur = 8.49 moles

                 ⇒ moles of Iron = 8.49 moles × 8

                                            = 67.92 moles

We can find the mass of copper by finding the difference between the mass of the crucible and the copper, and just the crucible. This is possible since the mass that is left would be attributed to just the copper.

Mass of copper = (Mass of crucible + copper) - Mass of crucible

                          = 5.92 g - 4.65 g

                          = 1.27 g

I don’t know what recording station you’re referring to but, When seismic waves reach the seismograph, a graphical record, or seismogram, is produced

Explanation:

The seismic waves hitting the recording station has been resulted in the seismograph, that has been evident of the earthquake.

The seismic wave has been the radiation, with the result of the movement of the earth surface. The movement has been result in the earthquake.

The intensity of the earthquake has been measured by seismograph on the Richter scale. The seismic wave results in the movement of the leads to the production of the seismograph.

Answer:

2CHCl3 + 5/2 O2 => 2CO2 + H20 + 3Cl2

Explanation:

Left Hand Side(LHS)

We have CHCl3 and O2

Right Hand Side(RHS)

We have CO2, H2O and Cl2

Balancing

To make sure that they have same values, put 2 before CHCl3 giving 2CHCl3 and 3 on Cl2(RHS) for chlorine gas giving 3Cl2

H2O remains the same

Before CO2 put 2 giving 2CO2

To make sure that oxygen is balanced put 5/2 before it. This gives 5/2 O2 (2 cancels out don't worry)

Combining all;

2CHCl3 + 5/2 O2 => 2CO2 + H20 + 3Cl2

I hope this helps. Have a nice studies.

Explanation:

Taking into account the definition of calorimetry, the change in temperature of a 5.0 g sample of water that loses 1800J of heat energy is 86.12 C.

In first place, calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.

Sensible heat is the amount of heat that a body can receive or give up without affecting its molecular structure. If the molecular structure does not change, the state (solid, liquid, gaseous) does not change. Since the molecular structure does not change, a change in temperature is observed.

In other words, sensible heat is the amount of heat that a body absorbs or releases without any changes in its physical state (phase change).

So, the equation that allows to calculate heat exchanges is:

Q = c× m× ΔT

where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.

In this case, you know:

Replacing in the expression to calculate heat exchanges:

1800 J= 4.18[tex]\frac{J}{gC}[/tex]× 5 g× ΔT

Solving:

1800 J ÷ (4.18[tex]\frac{J}{gC}[/tex]× 5 g)= ΔT

ΔT= 86.12 C

In summary, the change in temperature of a 5.0 g sample of water that loses 1800J of heat energy is 86.12 C.
