A man heats a balloon in the oven. The balloon initially measures 0.402 L with a temperature of 20.0°C, what will the volume of the balloon be after he heats it to a temperature of 250.0°C?

Answers

Answer 1

The volume of the balloon after he heats it to a temperature of 250.0°C is 0.718L.

How to calculate volume?

The volume of a balloon at a particular temperature can be calculated by using the Charles law formula as follows:

V1/T1 = V2/T2

Where;

V1 = initial volumeV2 = final volumeT1 = initial temperatureT2 = final temperature

According to this question, a man heats a balloon in the oven. The balloon initially measures 0.402L with a temperature of 20.0°C. However, the volume of the balloon after he heats it to a temperature of 250.0°C can be calculated as follows:

T1 = 20°C + 273 = 293KT2 = 250°C + 273 = 523K

0.402/293 = V2/523

523 × 0.402 = 293V2

210.25 = 293V2

V2 = 210.25/293

V2 = 0.718L

Therefore, the volume of the balloon after he heats it to a temperature of 250.0°C is 0.718L.

What proportion of z-scores fall between the z-score of -0.22 and a z-score of 1.7?
a) 0.4554
b) 0.0871
c) 0.5425
d) 0.4129

Answers

The proportion of z-scores fall between the z-score of - 0.22 and a z-score of 1.7 is 0.5425.

When assessed in terms of standard deviation units, a raw score's location in relation to its distance from the mean is indicated by a z-score. The z-score is positive when a value is above the mean and negative when a value is below the mean.

Because it standardizes the distribution, it enables comparison of scores on many types of variables, hence the name "standard score." A normally shaped distribution with a mean of 0 and a standard deviation (SD) of 1 is known as a standard normal distribution (SND).

The two z scores given are -0.22 and 1.7.

Now, according to the z score value table, we get;

For z score value - 0.22,

The area between the mean and z is 0.0871.

For a z score value of 1.7,

The area between the mean and z is 0.4554.

Then the proportion of z scores falling between the z score of - 0.22 and a z score of 1.7 will be:

0.0871 + 0.4554 = 0.5425

The correct option is (c).

among the elements of the main group, the general trend in the first ionization energy moving across a period is not followed between group 2 and group 13. which best explains these exceptions?

Answers

Due to the full s orbital's protection of the electron entering the p orbital, the ionization energy drops.

The full s orbital shields the electron as it enters the p orbital, lowering the ionization energy.

This process of "shielding" reduce s the net force acting on the outer shell electrons by a large amount when each new electron experiences both nucleon attraction and S orbital repulsion forces. Ionization energy consequently drops during these groupings.

The energy needed to free the outermost, or least bound, electron from an element's neutral atom is known as the first ionisation energy. First ionisation energy normally rises from left to right across a period on the periodic table. The outermost electron is more tightly connected to the nucleus as a result of the increased nuclear charge.

how many protons, neutrons and electrons are there in a neutral atom of the isotope of chlorine named chlorine-35?

Answers

Taking into account the definition of mass number, atomic number and charge of an atom, the number of protons and electrons of the isotope of chlorine named chlorine-35 is 17, while the number of neutrons is 18.

Subatomic particles

All atoms are made up of subatomic particles: protons and neutrons, which are part of their nucleus, and electrons, which revolve around them.

Atomic number

The atomic number indicates the number of protons that are present in the nucleus of an atom.

If the atom is electrically neutral, the positive charge of the protons is balanced by the negative charge of the electrons. That is, the number of protons in the nucleus is equal to the number of electrons in its orbitals, so that in a neutral atom the atomic number also indicates the number of electrons.

Mass number

The mass number indicates the total number of particles in the nucleus. That is, the mass number is the sum of the number of protons and the number of neutrons in the atomic nucleus.

Number of protons, neutrons and electrons in chlorine-35

The atomic number of chlorine is 17, while the mass number of chlorine-35 is 35.

So, being a neutral atom, by definition of atomic number the amount of protons and electrons that the isotope of chlorine has is 17.

Finally, knowing the number of protons and the atomic mass of the isotope, the number of neutrons is calculated by:

35 =17 + number of neutrons

35 - 17 = number of neutrons

18= number of neutrons

In summary, the number of protons and electrons of the isotope of chlorine named chlorine-35 is 17, while the number of neutrons is 18.

What mass of copper atoms have the same number of atoms as there are in a 4.21 gram sample of silicon?

Answers

The mass of copper atoms have the same number of atoms as there are in 4.21 g sample of silicon is 9.55 g

Avogadro's hypothesis

1 mole of silicon = 6.02×10²³ atoms

But

1 mole of silicon = 28 g

Thus, we can say that:

28 g of silicon = 6.02×10²³ atoms

How to determine the atoms in 4.21 g of silicon

28 g of silicon = 6.02×10²³ atoms

Therefore,

4.21 g of silicon = (4.21 × 6.02×10²³) / 28

4.21 g of silicon = 9.05×10²² atoms

Thus, 9.05×10²² atoms is present in 4.21 g of silicon

How to determine the mass of copper that contains 9.05×10²² atoms

From Avogadro's hypothesis ,

6.02×10²³ atoms = 1 mole of copper

But

1 mole of copper = 63.55 g

Thus, we can say that:

6.02×10²³ atoms = 63.55 g of copper

Therefore,

9.05×10²² atoms = (9.05×10²² × 63.55) / 6.02×10²³

9.05×10²² atoms = 9.55 g of copper

To increase the pH and react with the contaminants to create soluble calcium organic compounds that can be removed, hydrated lime is added to the juice. Lime excess is eliminated through carbonation or phosphoric acid addition. Depending on the needed level of final product purity, this process could be done numerous times.Two independent processes are involved in the production of sugar: (a) turning sugar cane or sugar beets into raw sugar, and (b) turning the raw sugar into refined sugar.

Which bases can be used to deprotonate a terminal alkyne? choose all that apply.

Answers

NaNH₂ can be used to deprotonate a terminal alkyne.

An analogous term (pKa) can be used to describe the acidity of terminal alkynes because they are mildly (i.e. weak) acidic. In this case, too, the lower the pKa value, the stronger the acid.

Alkynes have pKa values of around 25, therefore sodium amide, or NaNH₂, is an excellent (strong, that is) base that can deprotonate them. Indeed, sodium amide does deprotonate terminal alkynes (it can be used for elimination reactions, too).

This is possible because the NH₂⁻ anion is the conjugate base of Ammonia (NH₃) and, as a general acid-base principle, the weaker the acid, the stronger its conjugate base (Conjugate acid). Since ammonia has a pKa of about 38, NH₂⁻ is indeed a very strong base.

Sodium amide can deprotonate terminal alkynes (and alcohols, too) and it is often used when an Acetylide ion (RC₂⁻) is needed. These ions are then extremely helpful intermediates in the synthesis of organic compounds because they can react in a wide range of reactions as nucleophiles.

Facilitated diffusion :

The diffusion of solutes across the plasma membrane is facilitated by transport proteins. Passive transport is facilitated diffusion. Even though transport proteins are involved in facilitated diffusion, it is still passive transport because the solute is moving across the concentration gradient.

Why is it called facilitated diffusion?

Passive transportation is facilitated transport. Unlike simple diffusion, which occurs when materials pass through a membrane without the assistance of proteins, facilitated transport, also known as facilitated diffusion, occurs when materials diffuse across the plasma membrane with the assistance of membrane proteins.
