What is the similarity between speed and vilocity

Answers

Speed and velocity both represent a way to measure the change in position of an object relative to time. In fact, for a straight line motion, the speed and velocity of an object are the same (since distance and displacement will be the same). Speed and velocity are measured in the same units: meters per second or m/s.

Answers

Answer:

485 torr

Explanation:

Explanation:

We can solve this equation using the combined gas law:

P1V1/T1=P2V2/T2

Remember, always use the absolute (Kelvin) temperature when working with gas equations.

The temperature conversions are

T1=C+273=35o+273=308K

T2=57C+273=330K

Since we're trying to find the final pressure, let's rearrange this equation to solve for

P2:

P2=P1V1T2/T1V2

Our known values:

P1= 550 torr

V1=350mL

T1=308K

V2=425"mL

T2=330K

Let's plug these into the equation to find the final pressure:

The final pressure after it is subjected to these changes is thus 485torr

If a buffer has an initial pH of 6.34 and the acid has a Ka of 3.46 × 10-4, what is the ratio of conjugate base to weak acid in the buffer system?

Answers

Answer: The ratio of conjugate base to weak acid in the buffer system is 758 : 1

Explanation:

The dissociation constant for  acid = [tex]K_a=3.46\times 10^{-4}[/tex]

pH = 6.34

First we have to calculate the value of [tex]pK_a[/tex].

The expression used for the calculation of [tex]pK_a[/tex] is,

[tex]pK_a=-\log (K_a)[/tex]

Now put the value of [tex]K_a[/tex] in this expression, we get:

[tex]pK_a=-\log (3.46\times 10^{-4})[/tex]

[tex]pK_a=3.46[/tex]

Now we have to calculate the ratio of conjugate base to weak acid in the buffer system

Using Henderson Hesselbach equation :

[tex]pH=pK_a+\log \frac{[\text {conjugate base}]}{[Acid]}[/tex]

Now put all the given values in this expression, we get:

[tex]6.34=3.46+\log \frac{[\text {conjugate base}]}{[Acid]}[/tex]

[tex]\frac{[\text {conjugate base}]}{[Acid]}=758[/tex]

Therefore, the ratio of conjugate base to weak acid in the buffer system is 758: 1

What does a dissolved salt look like?
A. The salt crystals are surrounded by water molecules.
B. The salt crystals separate into salt molecules in the water.
C. The salt separates into ions that settle to the bottom
D. The ions in the salt are surrounded by water molecules.

Answers

Answer:

I want to say your answer is B)

The answer is D because the ions in the salt will be surrounded by water molecules

Dissolution in water occurs as a result of ionic interactions. This means that the ions (charged atoms) of the solute has to interact with the ions of water for the solute to dissolve. Based on this principle, only polar compounds can dissolve in water.

According to this question, salt is polar because it contains positive (+) and negative (-) ions. Hence, when placed in water, these ions will interact with the ions of water i.e. H+ and OH-. This causes dissolution of salt in water to form salt solution.

Hence, a dissolved salt will look like "ions in the salt are surrounded by water molecules".

3. Using formal charge formula (or electronegativity differences), to determine
the following the best structure, OCS, COS or CSO.

Answers

Answer:

Here's what I get  

Explanation:

1. Trends in atomic size

Atomic size tends to decrease from left to right across the Periodic Table.

You are adding one electron at a time. the electrons repel each other, so the size should increase.

You are also adding a proton to the nucleus. The additional attraction should pull the electrons closer to the nucleus.

The nuclear pull wins, so the atoms get smaller from left to right

Atomic size increases from top to bottom of a Group.

You are adding electrons to an extra shell, so the size should increase.

You are also adding protons to the nucleus, so the size should decrease.

The size of the outer shell wins, so the atomic size increases going down a Group.

2. Lewis structures

(a) Ammonium ion

N is the central atom. The N atom has the positive charge.

(b) Sulfur trioxide

S is the central atom, with a double bond to each of the three O atoms.

(c) Hydrogen cyanide

C is the central atom, with a triple bond to the N atom.

3. COS

The best structure is that of O=C=S. It has no formal charges.

The Lewis structures for the other arrangements have formal charges.

The correct answers of this question is given below.

1. The atomic size increases going down a Group.2. (a) Ammonium ion : The N atom has the positive charge.    (b) Sulfur trioxide : Having double bond to each of the three O    atoms.    (c) hydrogen cyanide : Having a triple bond to the N atom.3. COS and it has no formal charges

Explanation:

can somebody help me name these organic compound plz​

Answers

Answer:

A. 3–Ethyl–2–methylpentane.

B. 3–Ethyl–1,5,5–trimethylcyclohexene.

Explanation:

To name the compound, we must observe the following:

1. Locate the longest continuous carbon chain. This gives the parent name.

2. Identify the substituent groups attached.

3. Locate the position of the substituent groups by giving them the lowest possible low count alphabetically.

4. Combine the above to name the compound.

Now let us name the above compounds

For compound (A)

1.The longest chain is carbon 5 i.e pentane.

2. The substitute attached are:

Ethyl => CH2CH3

Methyl => CH3

3. Ethyl comes before methyl alphabetically. But considering the structure of the compound, ethyl assume same position from either side of the compound. Therefore, we'll consider the lowest possible count for methyl. Therefore, their position is given below:

Ethyl => CH2CH3 => carbon 3.

Methyl => CH3 => carbon 2.

4. The name of the compound is:

3–Ethyl–2–methylpentane.

Compound B.

This is a cyclic structure.

1. The parent name is cyclohexene.

2. The substitute groups attached are:

Ethyl => CH2CH3

Methyl => CH3

3. Since the compound is unsaturated, the functional group is the double bond. Hence, we shall start our counting from the double bond and also considering alphabetical order of the substituent.

Please note methyl (CH3) appears three times.

Ethyl => CH2CH3 => carbon 3

Methyl => CH3 => carbon 1, 5 and 5.

4. The name of the compound is:

3–Ethyl–1,5,5–trimethylcyclohexene

Answers

i think the answer is 1.31m

hope this helps :)

A student determines that she used 0.0665 mole of sodium hydroxide (NaOH) to completely titrate 25.00 mL of sulfuric acid solution. The molarity of the sulfuric acid is 1.31 M. Therefore, option C is correct.

What is molarity?

Number of moles of solute per liter of solution is known as molarity.

The balanced chemical equation for the reaction between sodium hydroxide and sulfuric acid is:

2 NaOH + H₂SO₄ → Na₂SO₄ + 2 H₂O

According to the balanced equation, one mole of sulfuric acid reacts with two moles of sodium hydroxide. Therefore, the number of moles of sulfuric acid in the titrated solution can be calculated as:

moles of H₂SO₄ = (moles of NaOH) / 2

moles of H₂SO₄ = 0.0665 mol / 2

moles of H₂SO₄ = 0.03325 mol

The volume of the sulfuric acid solution used in the titration is 25.00 mL, which is equivalent to 0.02500 L. The molarity (M) of the sulfuric acid can be calculated as:

Molarity of H₂SO₄ = moles of H₂SO₄ / volume of H₂SO₄ solution in liters

= 0.03325 mole / 0.02500 L

= 1.31 M

Thus, option C is correct.

What is a dehydration reaction?

A reaction where two smaller molecules are combined in a chemical manner by the removal of an element from each of these molecules is called a dehydration reaction. Organic compounds are classified on the basis of structure. They are classified as aliphatic and aromatic compounds. Different kinds of chemical reactions are involved in the formation of new compounds when there is a change in bonding between the atoms.

There are some chemical reactions that form a molecule and some only show a displacement or substitution of atoms. There are synthesis or combination reactions that involve a combination of two substances to form one molecule.

On the other hand, there are decomposition reactions in which one substance decomposes to form more than one substance. There are displacement reactions which can be single or double displacement. They involve the displacement of one or more components of compounds among each other. Addition, substitution, rearrangement, elimination, and oxidation-reduction reactions are some of the common organic reactions.

Therefore, the correct option is A.
