What is the kinetic energy of 3500 kg bus that is moving at 25 m/s

Answers

Answer:

1093750 J

Explanation:

The kinetic energy of an object can be found by using the formula

[tex]k = \frac{1}{2} m {v}^{2} \\ [/tex]

v is the velocity

m is the mass

From the question we have

[tex]k = \frac{1}{2} \times 3500 \times {25}^{2} \\ = 1750 \times 625 \\ = 1093750 \: \: \: \: \: [/tex]

We have the final answer as

Which property or properties can change when the pressure of a gas changes?

Answers

Answer: This law states that the volume and temperature of a gas have a direct relationship: As temperature increases, volume increases, when pressure is held constant. Heating a gas increases the kinetic energy of the particles, causing the gas to expand

Explanation:

According to this law, a gas's volume and temperature are directly correlated: When pressure is held constant, volume rises as temperature rises. The kinetic energy of the particles in a gas increases when it is heated, which causes the gas to expand.

What rules apply to gases?

According to Boyle's Law, when the temperature and mass are both constant, the volume of a given volume of gas sustained at a constant temperature varies inversely with the applied pressure.

The quantity of gas particles, the volume of the container, and the temperature of the gas all affect the pressure of a gas that is confined. The pressure will rise as the amount of gas particles in a container increases. The pressure will rise as a container's volume increases.

how is the strength of an acid affected by the number of hydrogen ions it contains​

Answers

Answer:

The greater the number of hydrogen ions, the increase in the acid strength.

Explanation:

Hydrogen ions determine the pH of the acid, greatest number of hydrogen ions give the pH value below 4 hence strong acid, and least number of hydrogen ions give a pH value above 4 but less than 7 hence a weak acid

What is Zeff of phosphorus

Answers

Answer:

Explanation:

Here is an illustration showing how to "calculate" +5 as the effective nuclear charge (Zeff) for phosphorus. We are not implying that the electrons are in orbits here, this is simply showing inner shell electrons that shield the outer valence electrons from the full nuclear charge.

We have that The effective nuclear charge Z_{eff} of 3p electron in phosphorus atom is discovered to be approximately 4.80

[tex]Z_{eff}=4.8[/tex]

It is important to note that the Z_{eff} of an element can be defined simply as the average positive charge felt by an shell electron in an atom from the various electrons around it

Hence

The effective nuclear charge Z_{eff} of 3p electron in phosphorus atom is discovered to be approximately 4.80

Why is accidental overlap of signals much more common in H-1 NMR than in C-13 NMR?

Answers

Answer:

See explanation

Explanation:

Accidental overlap of signals are common in H-1 NMR than in C-13 NMR for the following reasons;

1) 13C has a very low  natural abundance compared to H-1

2) 13C nucleus is s many times lesser in NMR sensitivity than H-1 nucleus.

3) As a result of its low abundance,  13C-13C coupling is not common.

4) Longer relaxation times do not give room for integrations.

5) Peaks in 13C spectra mainly consists of single lines.

As a result of all these, 13C-NMR spectra take longer to acquire than H-NMR. Hence, accidental overlap of signals is much more common in H-1 NMR than in C-13 NMR.

What would happen to the rate of a reaction with rate law rate = k [NO]^2[H2] if
the concentration of NO were halved?
A. The rate would be four times larger.

B. The rate would also be halved.

C. The rate would be one-fourth.

D. The rate would be doubled.

Answers

The rate of a reaction would be one-fourth.

Further explanation

Given

Rate law-r₁ = k [NO]²[H2]

Required

The rate of a reaction

Solution

The reaction rate (v) shows the change in the concentration of the substance (changes in addition to concentrations for reaction products or changes in concentration reduction for reactants) per unit time.  

Can be formulated:  

Reaction: aA ---> bB  

[tex]\large{\boxed{\boxed{\bold{v~=~-\frac{\Delta A}{\Delta t}}}}[/tex]

or  

[tex]\large{\boxed{\boxed{\bold{v~=~+\frac{\Delta B}{\Delta t}}}}[/tex]

The concentration of NO were halved, so the rate :

[tex]\tt r_2=k[\dfrac{1}{2}No]^2[H_2]\\\\r_2=\dfrac{1}{4}k.[No]^2[H_2]\\\\r_2=\dfrac{1}{4}r_1[/tex]

Answer:

C. The rate would be one-fourth.

Another option would be:

The rate would be four times larger

Why reaction between phosphorus and oxygen produces four atoms of phosphorus and five atoms of oxygen

Answers

Answer:

Reaction between an oxygen and  a phosphorus will produce oxides of phosphorus.

Explanation:

Reaction between oxygen and phosphorus produces four atoms of phosphorus with five atoms of oxygen. Sometimes it produces two atoms of phosphorus and five atoms of oxygen and sometimes four atoms of phosphorus and six atoms of oxygen. It does so depending upon the availability of oxygen. The size of phosphorus atom  interferes with the ability to form a double bonds to the other elements, such as nitrogen, oxygen, etc.
