nomenclature of this compound
​

1 mL =\(10^{-3}\) L

so $155$ mL =$155\times10^{-3}$ L

Now, $1$ gallon = $3.785$ L , or $1$ L= $\frac1{3.785}$ gallons

so $155\times10^{-3}$ L= $155\times10^{-3}\times \frac{1}{3.785}=40.95\times 10^{-3}$ gallons

and this is for each day, so just divide by 1 (day) to get the ratw gallons/day

i.e. $40.95\times 10^{-3}$ gal/day

Answer: 22.5 percent of incoming solar radiation goes directly to the surface of the Earth and is absorbed.

Explanation: Transfer of radiation through a planet's atmosphere. A planet and its atmosphere, in our solar system, can radiate back to space only as much energy as it absorbs from incoming solar radiation.

Answer:

Explanation:

I have the notes

"Only about 40 percent actually reaches the surface of the earth"

"our atmosphere and clouds reflect bout 40 percent of incoming solar radiation back into outer space"

"The remaining 60 percent is responsible for warming the earth"

"About 20 percent of this radiation is absorbed directly by the atmosphere"

The molecule with the structure of NBr5 cannot exist because nitrogen does not have a low enough electronegativity to be the central atom of this molecule. The correct option is (D).

In the given molecule, nitrogen is the central atom and is bonded with three bromine atoms. Nitrogen has five valence electrons, and each bromine has seven valence electrons. To complete the octet of each atom, a total of 32 valence electrons are required.

However, if we try to draw the Lewis structure for this molecule, we find that it is not possible to complete the octets for all six atoms using only valence electrons.

Additionally, nitrogen is more electronegative than bromine, meaning it attracts electrons more strongly. Thus, it is unlikely for nitrogen to be a terminal atom in a molecule with a halogen like bromine. Therefore, nitrogen cannot be the central atom in a molecule with three bromine atoms, and such a molecule cannot exist. Option (D) is the correct answer.

The majority of carbon dioxide in the body is transported in the form of bicarbonate ions (\(HCO_{3-}\)) in the blood.

When carbon dioxide (\(CO_{2}\)) enters the red blood cells, it reacts with water (\(H_{2}O\)) to form carbonic acid (\(H_{2}CO_{3}\)).

This reaction is catalyzed by an enzyme called carbonic anhydrase. Carbonic acid then dissociates into a bicarbonate ion (\(HCO_{3-}\)) and a hydrogen ion (H+).

The bicarbonate ion is transported out of the red blood cells and into the plasma, while the hydrogen ion binds to hemoglobin or is buffered by bicarbonate in the plasma.

This process helps to regulate the pH of the blood and ensures that the body's tissues receive an adequate supply of oxygen.

0.0917 grams of KOH are needed to neutralize 13.6 mL of 0.12 M HCl in stomach acid.

What is stomach acid?

Stomach acid, also known as gastric acid or gastric juice, is a digestive fluid that is produced in the stomach. It plays a vital role in the process of digestion by breaking down food and providing an acidic environment for the activation of digestive enzymes. Stomach acid is primarily composed of hydrochloric acid (HCl) along with other substances such as mucus, enzymes, and electrolytes.

The balanced equation for the neutralization reaction between HCl and KOH is:

HCl + KOH → KCl + H₂O

From the balanced equation, we can see that the stoichiometric ratio between HCl and KOH is 1:1. This means that for every mole of HCl, we need 1 mole of KOH to completely neutralize it.

First, let's calculate the number of moles of HCl in 13.6 mL of 0.12 M solution:

moles of HCl = volume (in L) * concentration (in mol/L)

= 0.0136 L * 0.12 mol/L

= 0.001632 mol

Since the stoichiometric ratio between HCl and KOH is 1:1, we need an equal number of moles of KOH to neutralize the HCl. Therefore, we need 0.001632 mol of KOH.

Next, we can calculate the mass of KOH using its molar mass:

mass of KOH = moles of KOH * molar mass of KOH

= 0.001632 mol * (39.10 g/mol + 16.00 g/mol + 1.01 g/mol)

= 0.001632 mol * 56.11 g/mol

= 0.0917 g

Therefore, 0.0917 grams of KOH are needed to neutralize 13.6 mL of 0.12 M HCl in stomach acid.

When selecting a material for a safe baking dish, consider its thermal stability, non-reactivity, inertness, resistance to corrosion, and food-grade safety. These chemical properties will help ensure that the baking dish is safe and durable for use in a cooking environment.

When choosing a material to make a safe baking dish, it is important to consider the following chemical properties:

1. Thermal stability: The material should be able to withstand high temperatures without breaking down or releasing harmful substances.

2. Non-reactivity: The material should not react with the food or other substances in the oven, ensuring that the dish remains safe for use and does not affect the taste or quality of the food.

3. Inertness: The material should be inert, meaning it does not participate in any chemical reactions with the food or oven environment.

4. Resistance to corrosion: The material should resist corrosion from food acids, salts, and moisture present in the baking environment.

5. Food-grade safety: The material should be certified as food-grade, ensuring that it is safe for contact with food and does not pose any health risks.

The approximate temperature of the H₂O after thermal equilibrium was reached is 23.4°C (option d).

The amount of heat absorbed by the water is given as 300.0 J. The mass of water is 50.0 g and the specific heat capacity of water is 4.2 J/g°C. Let's use the equation:

Q = m * c * ΔT

where Q is the heat absorbed, m is the mass of the water, c is the specific heat capacity of water, and ΔT is the change in temperature.

Substituting the given values, we get:

300.0 J = 50.0 g * 4.2 J/g°C * ΔT

Solving for ΔT, we get:

ΔT = 300.0 J / (50.0 g * 4.2 J/g°C) = 1.43°C

The final temperature of the water can be calculated by adding the change in temperature to the initial temperature:

Final temperature = 22.0°C + 1.43°C ≈ 23.4°C

Therefore, the approximate temperature of the H₂O after thermal equilibrium was reached is 23.4°C (option d).

To find the new volume of the container, we can use Boyle's Law, which states that the pressure and volume of a gas are inversely proportional at constant temperature.

Boyle's Law formula: P1 * V1 = P2 * V2

Where:

P1 = Initial pressure

V1 = Initial volume

P2 = Final pressure

V2 = Final volume

Given:

P1 = 1.5 atm

V1 = 3.0 L

P2 = 2.0 atm (new pressure)

V2 = ? (new volume)

Using the formula, we can solve for V2:

P1 * V1 = P2 * V2

1.5 atm * 3.0 L = 2.0 atm * V2

Simplifying the equation:

4.5 L·atm = 2.0 atm * V2

Dividing both sides of the equation by 2.0 atm:

4.5 L·atm / 2.0 atm = V2

V2 = 2.25 L

Therefore, the new volume of the container is 2.25 L.

The statement "Reaction of heating potassium permanganate produces potassium manganate" is false.

The reaction of heating potassium permanganate (KMnO₄) does not produce potassium manganate (K₂MnO₄). Instead, it undergoes a thermal decomposition reaction, resulting in the formation of different products.

When heated, potassium permanganate decomposes into potassium manganate (K₂MnO₄), manganese dioxide (MnO₂), and oxygen gas (O₂).

The reaction can be represented as follows:

2 KMnO₄(s) → K₂MnO₄(s) + MnO₂(s) + O₂(g)

Therefore, heating potassium permanganate leads to the formation of potassium manganate, along with manganese dioxide and oxygen gas. The color change from purple to green observed during the reaction is due to the formation of potassium manganate.

However, it is important to note that potassium manganate is not the sole product of the reaction but one of the products alongside manganese dioxide and oxygen gas.
