Answer 1

Answer:

1.  c

2. ionic

3. c

4. ionic

5. alloy or ionic

Explanation:

Answer 2

The compound classification.

The compounds are classified as per several different criteria and one common elements is the specific element that is present this makes it an iconic or a molecular. The presence of the oxides, hydrides, and various atomic groups.

Hence the answer is melting point to conductivity classified as c, iconic, c, iconic, and alloy.

A poor conductor of electricity will have a conductivity classification of c. The 396 good conductors will be iconic and a 0 C not teste will have a conductivity of c. The 200 C of good conductor will be iconic and 20 C of good conductor will be alloy or iconic.

Which statement is true about a rock layer deposited on top of another rock layer?
A- It is younger than the rock layer below.
B- It is older than the rock layer below.
C- It is the same age as the rock layer below.
D- It is no different than the rock layer below

Answers

Hello there!

Your answer is C.

Answer:

The right option is; A. It is younger than the rock layer below.

Explanation:

A rock layer deposited on top of another rock layer is younger than the rock layer below. This is based on the law of superposition which states that in any undeformed sequence of rocks that are laid down in layers, the youngest layer of rock will be on top of the sequence, while the oldest layer will be at the bottom of the sequence.

A gas occupies 11.2 liters at 0.860 atm. What is the pressure if the volume becomes 15.0 L? (Boyle)

Answers

Answer:

0.642 atm

Explanation:

The new pressure can be found by using the formula for Boyle's law which is

[tex]P_1V_1 = P_2V_2[/tex]

Since we are finding the new pressure

[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]

From the question we have

[tex]P_2 = \frac{11.2 \times 0.86}{15} = \frac{9.632}{15} \\ = 0.64213333...[/tex]

We have the final answer as

0.642 atm

Hope this helps you

Given:

Initial Volume [tex] \sf (V_1) [/tex] = 11.2 L

Initial Pressure [tex] \sf (P_1) [/tex] = 0.860 atm

Final Volume [tex] \sf (V_2) [/tex] = 15.0 L

To Find:

Final Pressure [tex] \sf (P_2) [/tex]

Concept/Theory:

[tex] \bf{ \underline{Boyle's \: Law} \: (Pressure - Volume \: Relationship)}[/tex]

"At constant temperature, the pressure of a fixed amount of gas varies inversely with the volume of the gas."

[tex] \bf{P \propto \dfrac{1}{V} \: (at \: constant \: T \: and \: n)}[/tex]

It can be also stated as "At constant temperature, the product of pressure and volume of fixed amount of a gas remains constant."

[tex] \bf{PV = Constant}[/tex]

If the initial pressure and volume of a fixed amount of gas at constant temperature are [tex] \sf (P_1) [/tex] & [tex] \sf (V_1) [/tex] and final pressure of the gas is [tex] \sf (P_2) [/tex] and volume occupied is [tex] \sf (V_2) [/tex], then according to Boyle's law;

[tex] \bf{P_1V_1 = P_2V_2 = Constant}[/tex]

OR

[tex] \bf{\dfrac{P_1}{P_2} = \dfrac{V_2}{V_1}}[/tex]

Answer:

By using Boyle's Law, we get:

[tex] \rm \longrightarrow \dfrac{0.860}{P_2} = \dfrac{15.0}{11.2} \\ \\ \rm \longrightarrow P_2 = \dfrac{11.2}{15.0} \times 0.860 \\ \\ \rm \longrightarrow P_2 = \dfrac{9.632}{15.0} \\ \\ \rm \longrightarrow P_2 = 0.642 \: atm[/tex]

[tex] \therefore [/tex] Final Pressure [tex] \sf (P_2) [/tex] = 0.642 atm

Hydrofluoric acid (HF) can be prepared according to the following equation:
CaF2 + H2SO4 2 HF + CaSO4.
How many grams of HF can be prepared from 75.0 g of H2SO4 and 63.0 g of CaF2?
In the above problem, which reactant is limiting and which is in excess?

Answers

Given the balanced equation:

( Reaction type : double replacement)

CaF2 + H2SO4 → CaSO4 + 2HFI

We can determine the number of grams prepared from the quantity of 75.0 H2SO4, and 63.0g of CaF2 by converting these grams to moles per substance.

This can be done by evaluating the atomic mass of each element of the substance, and totaling it to find the molecular mass.

For H2SO4 or hydrogen sulfate it's molecular mass is the sum of the quantity of atomic mass per element. H×2 + S×1 + O×4 = ≈1.01×2 + ≈32.06×1 + ≈16×4 = 2.02 + 32.06 + 64 = 98.08 u (Dalton's or Da) or g / mol.

For CaF2 or calcium fluoride, it's molecular mass adds 1 atomic mass of calcium and 2 atomic masses of fluoride due to the number of atoms.

Ca×1 + F×2 = ≈40.07×1 + ≈19×2 = 40.08 + 38 = 78.07 u (Da or Dalton's) or g / mol.

The limiting  reactant in the given balanced reaction is sulphuric acid. The mass of HF produced from 75 g of H₂SO₄ is 30 g.

What is limiting reactant?

The limiting reactant in a species is the reactant which is fewer in amount and thus determine the yield of the product.

In the given reaction, one mole of calcium fluoride reacts with one mole of sulphuric acid to give two moles of HF. The molar mass of calcium fluoride CaF₂ is 78 g/mol the weight taken here is 63 g. Thus number of moles is 63/78 = 0.87 moles.

The molar mass of sulphuric acid H₂SO₄ is 100g/mol. The weight taken here is 75 g and thus, number of moles is 75/100 = 0.75 moles. One mole of calcium fluoride need one mole of H₂SO₄ . Thus 0.87 neede 0.87 moles of H₂SO₄ . But here we have only 0.75. Thus it is the limiting reactant.

As per the reaction, one mole or 100 g of H₂SO₄  produce 2 moles or 40 g of HF (molar mass = 20 g/mol). Thus mass of HF produced from 75 g is calculated as follows:

mass of HF = (75 × 40)/100

                   =  30 g.

Hence, mass of HF produced in this reaction is 30 g.

Why do clothes stick together when coming out of a dryer? And do the clothes start off as neutral?

Answers

here is what came up when i searched it up:

"The attraction between protons and electrons can also make clothes stick together in the dryer. When you dry clothes in the dryer, different fabrics rub together, and electrons from a cotton sock (for instance) may rub off onto a polyester shirt."

Sometimes, clothes can get stuck together after they come out of a dryer because of static electricity.

No, clothes may not start off as neutral. Whether clothes have static charges before going into the dryer depends on different things.

Why do clothes stick together when coming out of a dryer?  

Static electricity happens when certain things touch and create an uneven amount of electrons. This can cause one material to have a positive charge and the other to have a negative charge. When clothes move and touch each other in a dryer, this rubbing can cause static electricity.

If the clothes are cleaned and dried correctly, they should have no charge or be evenly charged.

In each case, state whether the forces are balanced or unbalanced. If unbalanced, calculate the net force and describe the direction of the resultant force.

Answers

Answer:

Check explanation section.

Explanation:

In order to understand balanced force and unbalanced forces the first law of Newton should be considered as a basic knowledge.

For Balanced forces, there is equal equality in the direction of the forces. In balanced forces, there is no acceleration.

For unbalanced forces, there is acceleration that is go say there is going to be movement. Therefore, net force is equal to unbalanced forces.

Answer: since there is movement that is acceleration, then the force here is unbalanced force. The resultant force is downwards.towards the greater force direction.
