Explanation:
Why does water freeze at a temperature lower than 0°c when salt is added to it.
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 equation for the reaction between magnesium and hydrogen is written below
mg+2hcl------mgcl (2)+H (2)
(1) what mass of magnesium would be needed to give 50g of hydrogen? (mg=24, H=1)
(2) what volume would this gas occupy at s.t.p
Answer:
Explanation:
The balanced equation says that we'll get 1 mole of H2 for every 1 mole of Mg. 50 grams of H is 50g/2 g/mole = 25 moles of H2. That means we'll need 25 moles of Mg. Convert that into grams: (25 moles Mg)*(24.3 g/mole) = 607 grams Mg.
At STP, all gases occupy 22.4 liters/miole. That means 25 moles of H2 would occupy (25 moles)*(22.4 liters/mole) = 560 liters.
Which ground-state atom has an electron configuration described by the following orbital diagram?.
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.
Which statement describes the motion of the ice particles in the ice/water bath between minutes 5 and 20?
Choose the correct answer.
Particle motion stays the same because temperature does not change.
Particle motion stays the same because the ice is not completely melted yet.
Particle motion increases because thermal energy is being transferred to the ice.
Particle motion decreases because thermal energy is being transferred away from the ice.
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.

what are some advantages and disadvantages in acid rain management, in crop fields
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.

What is SN₂ reaction ?The SN2 reaction is a nucleophilic substitution reaction that breaks one bond while forming another. The rate-determining step of the reaction involves two reacting species. SN2 is an abbreviation for Substitution Nucleophilic Bimolecular.
The reaction is bimolecular because two molecules are present in the transition state, as indicated by the number 2 in the SN2 symbol. As a result, the rate of the reaction is affected by the concentrations of both the nucleophile and the substrate.
The SN2 reaction is a nucleophilic substitution with two components in the rate determining step. -SN2 reactions are bimolecular, with bond-forming and bond-breaking steps occurring simultaneously. There is no intermediate in -SN2 reactions.
Thus, product 1-methylprop-2-ene is obtained.

Answer:
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.

what general statements can you make about the relationship between the color of a solution and the color of light it absorbs?
The color absorbed is the complementary color to the color we perceive.
The color absorbed by an object and the color we perceive are complementary. All objects that we see have different colors. The color we see is always opposite to the color absorbed by the object in the color wheel.
Hence, the color wheel can be used to show the relationship between the color perceived and the color absorbed by the object. The color absorbed is the complementary color to the color we perceive.

methane is called an organic compound why
Answer:
Explanation:
1) Organic compounds always contain only p-block elements (Groups III-VII), at least one of which must be carbon. 2) Organic compounds almost always contain one or more C-H bonds. ... Thus, all bonds are typically covalent in organic compounds. Methane (CH4) is the prototypical organic molecule.
Methane contains carbon, forming covalent bonds, and is found in living organisms, making it an organic compound.
Methane (CH₄) is considered an organic compound due to its molecular structure and occurrence in living organisms. Organic compounds are primarily composed of carbon atoms covalently bonded to hydrogen and often other elements like oxygen, nitrogen, sulfur, and more.
Methane consists of one carbon atom bonded to four hydrogen atoms through covalent bonds. Carbon's unique ability to form stable covalent bonds with other elements, including itself, leads to the vast diversity of organic molecules found in living organisms.
Methane is a crucial component of natural gas and is produced by various biological and geological processes. It is present in the digestive systems of animals, formed during decomposition, and plays a role in carbon and energy cycles.
Its prevalence in living systems and its molecular structure classify methane as an organic compound, reflecting the foundational principles of organic chemistry.
