A solution is measured to have a pH of 2.3. What is most likely also true about the solution?1.)It has a low hydroxide ion concentration.
2.)It has a low hydronium ion concentration.
3.)It is neutral.
4.)It has no H2O molecules.

Answers

Answer 1

Answer: According to the pH scale, a solution that has a pH of < 7 is considered an acid. Since it is established that the solution is an acid, there will be a low OH- concentration (hydroxide ion) in solution. In terms of hydronium ion, an acid has a higher amount of hydronium ion concentration.

Change the following data into scientific notation.

5 000 000 km

Answers

To find out scientific notation, you want to make sure that number is less than 10. So do 5.000000, you don't rally need the zeros but I just want to make my point. So use 10^x meaning ten the whatever power adds zeros like 5.000000x10^6 meaning it is increasing it by six zeros moving it out of the decimals and letting become 5,000,000.

Answer:

the answer is B) 5x10^6

Which is an example of larceny? A. taking a man's wallet while threatening him with a firearm. B. taking $50 from an unattended purse. C. stealing a man's car? D. breaking into a home and stealing $10,000 cash

Answers

Taking $50 from an unattended purse is an example of larceny. The correct Option is B.

What is Larceny?

Larceny is a type of theft that involves the taking of someone else's property without their consent and with the intent to permanently deprive them of it. It is often referred to as "simple theft" and is considered a crime in most legal systems around the world.

Larceny can take many forms, including stealing money or goods from a store, taking personal property from an individual, or taking valuables from an unattended location. The key element of larceny is that the property is taken without the owner's consent, and the perpetrator intends to keep the property permanently.

The severity of the crime of larceny can vary depending on the value of the property stolen and the circumstances of the theft. In many legal systems, larceny is classified as a misdemeanor or a felony, with the latter carrying a more severe penalty.

In addition to criminal penalties, a person convicted of larceny may also be subject to civil lawsuits and may be required to pay restitution to the victim. Overall, larceny is a serious crime that can have significant consequences for both the perpetrator and the victim.

Here in the question,

Larceny is a type of theft that involves the taking of someone else's property without their consent, with the intent to permanently deprive them of it. It is often referred to as "simple theft."

Option A (taking a man's wallet while threatening him with a firearm) is an example of robbery, which involves the use of force or threat of force to take someone else's property.

Option C (stealing a man's car) is an example of grand theft auto, which is a specific type of larceny that involves the theft of a motor vehicle.

Option D (breaking into a home and stealing $10,000 cash) is an example of burglary, which involves unauthorized entry into a building with the intent to commit a crime, such as theft.

Therefore, the correct option that is an example of larceny is B (taking $50 from an unattended purse) as it involves the taking of someone else's property without their consent, with the intent to permanently deprive them of it.

Gaseous helium is in thermal equilibrium with liquid helium at 6.4 K. The mass of a helium atom is 6.65 × 10−27 kg and Boltzmann’s constant is 1.38066 × 10−23 J/K. Determine the most probable speed of a helium atom. Answer in units of m/s.

Answers

Answer:

162.78 m/s is the most probable speed of a helium atom.

Explanation:

The most probable speed:

$v_(mp)=\sqrt{(2K_bT)/(m)}$

$K_b$ = Boltzmann’s constant = $1.38066* 10^(-23) J/K$

T = temperature of the gas

m = mass of the gas particle.

Given, m = $6.65* 10^(-27) kg$

T = 6.4 K

Substituting all the given values :

$v_(mp)=\sqrt{(2* 1.38066* 10^(-23) J/K* 6.4 K)/(6.65* 10^(-27) kg)}$

$v_(mp)=162.78 m/s$

162.78 m/s is the most probable speed of a helium atom.
