What is responsible for the larger size of an anion in comparison with the atom from which it is form?

Answer:

They are examples of heterogeneous

Explanation:

By definition, a pure substance or a homogeneous mixture consists of a single phase. A heterogeneous mixture consists of two or more phases. When oil and water are combined, they do not mix evenly, but instead form two separate layers.

Explanation:

A strong electrolyte is usually defined as a substance that dissociates completely in solution to form ions.

A strong electrolyte will dissociate completely in solution and lead to a bright light. A nonelectrolyte will not light the bulb at all. A weak electrolyte or a substance that is not too soluble in water will produce a dim light.

Since CaBr2 is not as soluble in water as NaCl, it does not produce bright light as NaCl does hence 0.20 M solution of the solution will lead to a dim light.

Answer:

increase and then decrease

Explanation:

as a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter. As the frequency decreases, the wavelength gets longer. There are two basic types of waves: mechanical and electromagnetic

Answer:

We inhale oxygen through our nasal pasage and mouth, it passes epiglottis which leads air down to the lungs. It travels down the windpipe into right and left bronchi. Around alveoli (small air filled sacks) tiny capillaries bring blood to exchange gases. Oxygen moves from the lungs into the bloodstream and carbon dioxide moves from the bloodstream into the lungs where we exhale back from our mouth

The map is down below.

Explanation:

Answer:

so for every 1 kg it's 10 to the three. So we multiply 5.84 times 47.867 divided by 10 to the three, which is just 1000. Doing that should give you 0.280 kg of titanium.

Explanation:

The mass of 5.84 moles of titanium (Ti) is 0.279 kg.

Moles can be defined as the amount of substances present in a system that contain the same number of entities as the number of atoms in 12g of carbon 12.

Given moles of Titanium = 5.84 moles

Molar mass of Titanium = 47.867 g

Mass = Moles x Molar mass

Mass of Titanium = 5.84 x 47.867

= 279.54g

To convert in kgs = 279.54 / 1000

= 0.279kg

Hence, the mass of 5.84 moles of titanium (Ti) is 0.279 kg.

Answer:

iron

Explanation:

iron is the only metal in the answer choices that rusts because an oxidation reaction occurs as soon as it is exposed to water and oxygen.

Given parameters:

Radius of cylinder  = 1.045cm

Height of cylinder  = 30.48cm

Unknown:

Volume of the cylinder  = ?

A cylinder is a solid body. The volume is usually calculated using the mathematical expression below;

     Volume of cylinder  = π r² h

  π  = 3.141

   r  = radius of cylinder

   h = height of cylinder

Now, input the parameters and solve;

          Volume of cylinder  = 3.141 x 1.045² x 30.48

                                            = 104.547cm³

To the nearest tenth gives 104.5cm³

The volume of the cylinder is 104.5cm³

Answer:

Explanation:

Increasing the level of component measured doesn't really significantly affect density, with exception of weight and volume. the above serves to make density an effective property in the identification of several materials. 

According to the balanced equation 4Fe2O3 -> 6FeO + O2, we find that 4 moles of Fe2O3 produce 6 moles of FeO. Using this ratio, we can calculate that 8 moles of Fe2O3 will produce 12 moles of FeO.

To balance the equation:

Fe2O3 -> FeO + O2

We need to ensure that the number of atoms of each element is equal on both sides of the equation. Here's the balanced equation:

4Fe2O3 -> 6FeO + O2

From the balanced equation, we can see that 4 moles of Fe2O3 produce 6 moles of FeO.

To find how many moles of FeO are produced from 8 moles of Fe2O3, we can set up a proportion:

4 moles Fe2O3 / 6 moles FeO = 8 moles Fe2O3 / x moles FeO

Cross-multiplying and solving for x:

4 * x = 6 * 8

x = (6 * 8) / 4

x = 12

Therefore, 8 moles of Fe2O3 will produce 12 moles of FeO.

To get the net Ionic equation we must get rid of spectator ions, I.E. the ions that repeat on either side of the equation.

This becomes the following net ionic.

[tex]Ni_{2}[/tex][tex](aq)^{+}[/tex] + [tex]S_{2} (aq)^{2} -[/tex] → [tex]2NiS(s)[/tex]

Given balanced equation:

Fe₂O₃ + 2Al → Al₂O₃ + 2Fe

Molar masses:

Fe₂O₃: 159.69 g/mol

Al: 26.98 g/mol

Al₂O₃: 101.96 g/mol

The equation tells us that 1 mole of Fe₂O₃ reacts with 2 moles of Al to produce 1 mole of Al₂O₃.

Step 1: Calculate the number of moles of Al₂O₃ produced:

Using the mole ratio from the balanced equation, we find that the number of moles of Al₂O₃ is equal to the number of moles of Fe₂O₃ used.

So, the moles of Al₂O₃ produced = moles of Fe₂O₃ used = 1 mole.

Step 2: Convert moles to grams:

To convert moles of Al₂O₃ to grams, we multiply by the molar mass of Al₂O₃.

Grams of Al₂O₃ produced = moles of Al₂O₃ produced × molar mass of Al₂O₃

Grams of Al₂O₃ produced = 1 mole × 101.96 g/mol

Grams of Al₂O₃ produced = 101.96 grams

Therefore, 101.96 grams of aluminum oxide (Al₂O₃) are produced in the reaction.
