Both chairs are the same size and have the same number of molecules. The diagram above shows the chairs before they touch.
How does the temperature of the bottom chair compare with the temperature of the top chair before the chairs touch? What will happen after the chairs have been touching for a while?

The best way of characterizing the sucralose would be to say it is a molecule, but there is no such option. So, the closest options is "Compound", because it is composed by more than one element.

So, first blank is "Compound".

The elements on it are H, C and O. From an electronegativity table, we can see that the electronegativities are approximately:

H: 2.1

C: 2.5

O: 3.5

So, the least electronegative is H.

Second blank is "hydrogen".

The normal rule to follow is the octet rule, so we complete the shell by getting 8 electron in it.

But, the hydrogen has only 1 electron and it is on the first shell, so it can't complete the octet rule like normal, it follows the duet rule, that is, it completes 2 electrons.

Third blank is "Du".

The Sucralose is composed by nonmetals and hydrogen only, so they don't bond by ionic bonds, they form covalent bonds. Thus, they don't dissociate into ions.

Fourth blank is "False".

A bond is considered polar if the electronegativity of their elements are dfferent enough. When bonding C-C, both have the same electronegativity, so they are not polar, that is, they are non polar covalent bonds.

Fifth blank is "Non polar covalent".

O-H, on the other hand, have a very different electronegativities, one is 2.1 and the other is 3.5, so the bond will be polar.

Sixth blank is "Polar covalent".

Between the solid, liquid and gas phases, the gas is when the molecules are the most apart and solid is when the molecules are the closest. Since it is solid, the particules will be closer.

Seventh blank is "Closer".

Explanation:

Step 1 - Understanding the types of heat transfer

There are three types of heat transfer: conduction, convection and irradiation. Let's see how each one works:

a) Conduction: is when a very hot substance enters in contact with a cooler substance. The atoms in the hotter substance are moving with a greater velocity and will therefore collide with the atoms of the cooler substance.

b) Convection: it happens especially in liquids and air (fluids). The liquid is warmed up at the bottom first, via conduction. The heated bottom thus changes its density: it becomes less dense, and go up. This process repeats itself several times, warming the whole liquid.

c) Irradiation: when something is put near a heat source, but do not touch it directly. In this case, there's no direct atom collision, but indirect: the rapid atoms of the heat source collide with atoms in the air which then collide with the atoms in the object that is being heated.

Step 2 - Discovering the type of heat transfer in each scenario

In the first scenario, the water at the bottom is in direct contact with the pan. Therefore, water molecules will directly collide with "pan" molecules (probably aluminum atoms or other materials). But there's also convection. The water is not heated only by conduction.

In the second scenario, the hands are near the Bunsen burner, but not directly touching it. What is happening here is then heat irradiation, not conduction.

In the third scenario, the hand is touching the object (the handle of the pan). Even though handles are made of material that poorly conduct heat, it will increase its temperature, at least a little bit. When we touch it, we can feel it is hotter than before. In this case, only conduction is involved (from the handle to our hand). In this case atoms are directly colliding and this is the only source of heat.

Finally, in the last scenario, we also have a case of irradiation: the pan with water is near the heat source, but not directly touching it.

Step 3 - How to set an experiment

In science in general, anytime we want to investigate some effect it is good manners to investigate a system controling all other effects. We want to investigate a variable at a time.

Therefore, while both scenario 1 and 3 involve conduction, scenario 1 also involves convection, which could be a problem to a experiment intending to study conduction only.

The best experiment would be then scenario 3, hands touchind the handle of pan siting in a Bunsen burner.

Yes, both of them are considered lewis structures

Lewis structures are ways in which the valence electron of a compound are arranged around its elements using dots. It represents and shows how electrons are arranged around individual atoms.

In lewis structure, electrons are represented as dots and if it is a bonding electron, it can be represented as lines. Since the elements in the compound given are both non-metals, they are covalently bonded. This shows the reason why one of the lewis structures contains lines.

1. The volume of the cube (cm³) is 0.599 cm³

2. The density of the copper to two decimal place is 8.91 g/cm³

The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as

Density = mass / volume

V = L³

V = 0.843³

V = 0.599 cm³

Density = mass / volume

Density = 5.34 / 0.599

Density = 8.91 g/cm³

Hello!

In this case, since the decomposition of potassium chlorate is:

\(2KClO_3\rightarrow 2KCl+3O_2\)

We can see a 2:3 mole ratio between potassium chlorate and oxygen (molar mass 32.0 g/mol), thus, via stoichiometry, we compute the mass of oxygen that are produced by the decomposition of 2.50 moles of this reactant:

\(m_{O_2}=2.50molKClO_3*\frac{3molO_2}{2molKClO_3} *\frac{32.0gO_2}{1molO_2}\\\\m_{O_2}=120gO_2\)

acidic oxides are formed

metal oxides and basic oxides are basically the same.

A solution of 0.236 M NaOH containing 0.00576 molecules of hydroxide ions (OH-) is contained in 24.42 mL. Thus, 0.00288 molecules of sulfuric acid can be neutralised by 24.42 mL of 0.236 M NaOH. (H2SO4).

A neutralisation process between sodium oxide and sulfuric acid is represented by the equation above. (base and acid). An acid and a base react to create salt (Sodium Sulphate) and water as a byproduct.

We make the assumption that the hydroxide ions are present in a solution of sodium hydroxide in order to determine the number of moles of hydroxide ions (OH-) present in 24.42 mL. (NaOH)

First, we need to convert the volume of the solution from milliliters (mL) to liters (L):

24.42 mL = 0.02442 L

Next, we can use the concentration of NaOH to calculate the number of moles of OH-:

0.236 mol/L (concentration of NaOH) x 0.02442 L

= 0.00576 moles of OH-

20.0 moles of oxygen react with Antimony to form 13.3 moles of Antimony (III) Oxide. We want to calculate how many moles of Antimony (III) Oxide will be formed from 20.0 moles of oxygen. This is a stoichiometry problem.

The link between the proportional amounts of components participating in a reaction or generating a compound is known as stoichiometry, and it is often expressed as a ratio of whole integers.

Assuming a balanced chemical equation, the stoichiometric ratio between Antimony (III) Oxide  and oxygen can be used to determine the number of moles of Antimony (III) Oxide  formed.

For example, the balanced equation for the reaction of Antimony with O2 to form Antimony (III) Oxide  is:

4 Antimony + 3 O2 → 2 Antimony (III) Oxide

From this equation, it can be seen that 3 moles of oxygen react with 2 moles of Antimony (III) Oxide . Therefore, if there are 20.0 moles of O2, then the number of moles of Antimony (III) Oxide  formed would be:

20.0 moles oxygen × (2 moles Antimony (III) Oxide  / 3 moles oxygen) = 13.3 moles Antimony (III) Oxide.

Density is the ratio between the mass of a material and its volume (d = m/V) at a given temperature and pressure.

So first we need to find the mass of the material. We can do it calculating the mass of the flask with the liquid minus the mass of the flask without the liquid.

mass of the flask with the liquid = 184.0 g

mass of the flask without the liquid = 176.3 g

mass of the material = 184.0 - 176.3 = 7.7 g

Now we use the following equation: d = m/V

where:

d = density

m = mass = 7.7 g

V = 9.20 mL

d = 7.7/9.20

d = 0.84 g/mL

Answer: d = 0.84 g/mL

Explanation:

The application of force in the direction of the motion of an object. The second scenario involves applying force to a moving item that is traveling in the opposite direction.

A force is an influence that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. A force has both a direction and a magnitude.

Force is used to describe a body's tendency to modify or change its state as a result of an external cause. When force is applied, the body can also alter its size, shape, and direction.

A push or pull that an object experiences as a result of interacting with another item is known as a force. Every time two items interact, a force is exerted on each of the objects. The force is no longer felt by the two objects when the interaction ends.

Thus, Force applied to an item in motion that originates in any direction constitutes the third situation where force is created.
