John is going on a summer trip and can either stay at the Banks hotel near the ocean, or the Diamond hotel which is far inland. John wants to have warm weather and no rain on his trip. Which hotel should John stay at? (2 points)

The Banks hotel, because water from the ocean warms up the surrounding air in the summer.
The Banks hotel, because the water from the ocean heats up faster than land in the summer.
The Diamond hotel, because inland regions have less precipitation and warm faster than areas near oceans.
The Diamond hotel, because the ocean will carry warm air towards the inland regions.

Answer:

both bonding electrons come from the oxygen atom

Explanation:

A coordinate covalent bond is said to be formed when an electron pair is donated into a empty orbital of an atom from a filled orbital of another atom.

In this type of covalent bond, the shared electron pair is furnished by only one of the bonding species.

The bonding between H^+ and H2O to form H3O^+ involves donation of a lone pair of electrons on oxygen into the empty 1s orbital of  H^+ hence the two bonding electrons come from oxygen. This is why the bond is called a coordinate covalent bond.

Answer:

The intensity of the light bulb increases

Explanation:

The conductivity of a solution depends on the concentration of ions in solution. This implies that, if the concentration of ions in solution is increased, the conductivity of the solution increases accordingly.

If we add more CuSO4(s) to the CuSO4 solution, the concentration of ions in the solution and consequently the conductivity of the solution increases.

Therefore, the intensity of the light bulb increases.

Answer:

14.2L at STP

Explanation:

Based on the problem, 2 moles of NH3 produce 6 moles of HF. To solve this question we have to convert the mass of NH3 to moles. With the chemical equation find the moles of HF and using PV = nRT find the liters of HF:

Moles NH3 -Molar mass: 17.031g/mol-

3.6g NH3 * (1mol / 17.031g) = 0.211 moles NH3

Moles HF:

0.211 moles NH3 * (6mol HF / 2mol NH3) = 0.634 moles HF

Volume HF

PV = nRT; V = nRT/P

Where V is volume in liters, n are moles of the gas = 0.634 moles, R is gas constant = 0.082atmL/molK, T is absolute temperature = 273.15K at STP and P is pressure = 1atm at STP.

Replacing:

V = 0.634moles*0.082atmL/molK*273.15K / 1atm

V = 14.2L at STP

Answer:

Increasing number of electrons

Explanation:

London dispersion forces are intermolecular forces that occur due to momentary shifts in the electron cloud of atoms or molecules.

London dispersion forces are most commonly observed as the predominant kind of intermolecular forces in non-polar substances.

Generally, it is observed that the strength of these London dispersion forces tends to increase as the number of electrons in the substance increases.

Answer:

R = 40 ohms

Explanation:

Given that,

The voltage of outlet, V = 120 V

Current flowing through the device, I = 3 A

We need to find the Resistance rating of  the power cord. Let the resistance is R. We know that,

Ohm's law, V = IR

Put all the values,

[tex]R=\dfrac{V}{I}\\\\R=\dfrac{120}{3}\\\\R=40\ \Omega[/tex]

So, the resistance rating of the power cord is equal to 40 ohms.

Increasing the surface area between solute and solvent, increases the rate of dissolution.

Rate of any process will gives idea about the speed of the completion of that happening process.

Dissolution is a process in which solute particles gets dissolve in the solvent medium. If we increases the surface area of any one medium of the solution like solute or solvent then the rate of dissolution increases, as it increases the space to get attracted to each other.

Hence, option (d) is correct.

Answer:

Explanation:

To find the pH we must first find the pOH

The pOH can be found by using the formula

pOH = - log [ {OH}^{-} ]

We have

[tex]pOH = - log(8.2 \times {10}^{ - 8} ) \\ = 7.086186...[/tex]

pOH = 7.09

Next we use the equation

pH = 14 - pOH

We have

pH = 14 - 7.09

We have the final answer as

Yes, potassium metal can be used to react with an acid to prepare a soluble salt.

Acids react with metals to yield the corresponding metal salt and hydrogen gas.

One of the properties of metals is their ability to react with dilute acids to yield  a soluble salt and hydrogen gas. This is a common reaction for all metals that are above hydrogen in the activity series.

Potassium can react with a hypothetical acid HB as follows;

Answer:

B 2:2

Explanation:

Mole ratio is the comparison of the ratio of two compounds or elements in a chemical reaction. In a balanced equation, the moles of a particular compound or element is written as a coefficient. This means that mole ratio is the ratio of the coefficient of two substances in a reaction.

In this balanced chemical equation given as follows:

2CO + 02 → 2CO2

The number of moles/coefficient of carbon monoxide (CO) is 2 while that of carbon dioxide (CO2) is 2.

Hence, the mole ratio of CO to CO2 is 2:2

Explanation: if I water this plant twice a day then it will grow 3 feet because the more water it gets the bigger it grows

Answer:

I believe that it would be faster but the reaction would not happen immediately. It would take a long time for the effect to start kicking in but it will definitely speed up the process of CO2 being released into our atmosphere.

Explanation:

If CO₂ is being produced in the solution at a faster rate than H₂CO₃, then the rate of the forward reaction is faster.

Rate of any reaction tells about the duration of the completion of reaction to produce products.

Given chemical reaction is written as:

H₂CO₃ ⇄ CO₂ + H₂O

In the question it is given that CO₂ is produced at the faster rate, and it is the product of the forward reaction. So, we conclude that rate of forward reaction is faster.

Hence, the rate of forward reaction is faster.
