Draw the structure of the product that is formed when the compound shown below is treated with ch3co3h under aqueous acidic conditions.

Answer:

Disadvantages of acid rain:

• Acid rain affects the fresh water ponds and lakes and destroys the aquatic life as some species of fishes are rare and may be extinct

• it can affect the trees particularly those that are high altitude

• It can damage historical monuments and buildings

•soil can be affected and can lead to deaths of good microbes

Advantages of acid rain:

• it makes holes in limestone below ground, which creates caves and places to store groundwater, as well as providing habitat for some species

• But the new study shows that sulfuric in acid may have benefits, limiting global warming by counteracting the natural production of methane gases by microbes in wetland areas.

Answer:

the body can losse heat through Radiation,since Radiation does not involve the direct contact of two mediums

Answer:

yes

Explanation:

Answer:

The energy of atomic orbitals increases as the principal quantum number, n, increases. In any atom with two or more electrons, the repulsion between the electrons makes energies of subshells with different values of I differ so that the energy of the orbitals increases within a shell in the order s< p <d<f. Figure 1 depicts how these two trends in increasing energy relate. The 1s orbital at the bottom of the diagram is the orbital with electrons of lowest energy. The energy increases as we move up to the 2s and then 2p, 3s, and 3p orbitals, showing that the increasing n value has more influence on energy than the increasing I value for small atoms. However, this pattern does not hold for larger atoms. The 3d orbital is higher in energy than the 4s orbital. Such overlaps continue to occur frequently as we move up the chart.

Pressure Cooking

Explanation:

Pressure cooking is a very old cooking method that’s experienced a recent resurgence thanks to a new generation of cookers that promise a speedy, set-it-and-forget-it path to dinner. These devices, whether electrical or stovetop, are all much safer than those of decades ago (which tended to explode), with mechanisms to prevent them from accumulating too much pressure. If you read the owner’s manual carefully, however, you’ll still find one important precaution to take when cooking under pressure: adding water. Water and pressure cooking go hand in hand. In fact, it’s water that helps generate the high-pressure environment that makes your food cook faster.

Most pressure cooker instructions state a minimum amount of water required for pressure cooking even a tiny amount of food. Inside the tightly sealed pressure cooker, the water is heated and eventually boils into steam. Since the steam cannot escape, it collects above the food. All those trapped water molecules increase the pressure inside the cooker.

Answer: the answer is plasma membrane

Explanation:

Plasma membrane is made up of lipoproteins. There are two layers of lipids and the protein molecules are embedded in it. It is present in both plant cell and animal cell. The membrane is selectively permeable i.e., it allows only certain substances to pass.

The parts of the cell is made up of lipoprotein is Plasma Membrane. So, the correct option is (B).

The plasma membrane is made up of lipoproteins. There are two layers of lipids and protein molecules are embedded in it. It is present in both plant cell and animal cell. The membrane is selectively permeable i.e. it allows only certain substances to pass through.

The plasma membrane is also called the cell membrane which is a biological membrane that separates and protects the interior of all cells from the external environment. The plasma membrane controls the transport of materials entering and exiting the cell.

It provides a definite environment inside the cell. It also has many different functions such as transporting nutrients into the cell and removing toxins from the cell. The second is that the membrane of the cell, which would be the plasma membrane, would contain proteins that interact with other cells.

Thus, the parts of the cell is made up of lipoprotein is Plasma Membrane. So, the correct option is (B).

It is possible to divide cells into two classifications: eukaryotic cells, which have a nucleus, and prokaryotic cells, which do not possess a nucleus but do contain a nucleoid area. In contrast to prokaryotes, which are one-celled creatures, eukaryotes may be either single-celled or multicellular in nature.

It's easier to answer what makes it unsaturated.

H - C ≡ C - H

This is Acetylene. It has three shared bonds between the two carbons. That many bonds makes it unsaturated.

     H   H

H - C - C - H

     H   H

Draw lines from 1 H on top to the Carbon underneath Do the same with the other hydrogen. Make the two Hydrogens on the bottom do the same thing.

The point is that Carbon has 4 bonds. 1 bond goes to the other Carbon. The other 3 take on Hydrogen. That molecule is saturated: nothing can be added in its natural state.

Answer:

Salt molecules block water molecules from packing together when temperature is lowered. It then prevents them from becoming ice. More water molecules leave the solid phase than the ones entering the solid phase. Freezing point depression occurs when the freezing point of the liquid is lowered by addition of solute.

The volume of the dry nitrogen gas at STP is 57.4 mL

From the question given above, the following data were obtained:

Initial volume (V₁) = 77 mL

Initial temperature (T₁) = 50 °C = 50 + 273 = 323 K

Initial pressure (P₁) = 763 – 92.5 = 670.5 mmHg

Final temperature (T₂) = STP = 273 K

Final pressure (P₂) = 760 mmHg

The volume of the dry nitrogen can be obtained by using the combine gas equation as follow:

[tex] \frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2} \\ \\ \frac{670.5 \times 77}{323} = \frac{760 \times V_2}{273} \\ \\ cross \: multiply \\ \\ 323 \times 760 \times V_2 = 670.5 \times 77 \times 273 \\ \\ divide \: both \: side \: by \: 323 \times 760 \\ \\ V_2 = \: \frac{670.5 \times 77 \times 273 }{323 \times 760} \\ \\ V_2 = 57.4 \: ml[/tex]

mix the food with digestive juices that have acids and enzymes, breaking it into much smaller, digestible pieces

Explanation:

The ice cube which was solid has turned into the liquid water because the air temperature is warmer than the freezers. Which means the ice particles gather heat energy from the warmer air. Therefore the ice particles have enough energy to break apart (melt)into smaller particle arrangements.

Answer:

Q = 2.877 mole (4 sig. figs.)

Using Q = m·c·ΔT => m = Q/c·ΔT

Q = 27.16 Kj

c = 27.17 j/g·°C = 0.02717 Kj/g·°C

ΔT = 347.6 °C  

Q = 27.16 Kj/(0.02417j/mol·°C)(347.6°C) = 2.87.6869965 mol (calc. ans.)

D

Explanation:

Answer:

its not D it's B trust me

Explanation:

When particles move fast enough, these forces can no longer keep particles together.

Recall that the particles of a substance are in constant random motion. Hence, when more energy is added to the system, the particles within the system will have greater motion, and the temperature will increase.

The forces that keep molecules together in a particular state of matter are electrostatic forces. When particles move fast enough, these forces can no longer keep particles together.

It is common to use the analogy of an elastic material to represent the bonding between atoms in molecules. However, this analogy is not apt in a phase change because, for a phase change from liquid to gas, the bonds break completely and particles can move independently of each other.

We know that the average kinetic energy of the molecules of a substance depends on the temperature of the body. Therefore, a sample of liquid benzene at 80ºC and a sample of gaseous benzene at 80ºC will have the same average kinetic energy as benzene molecules.
