propose two different combinations of bonding features to account for an ihd of 5 in a molecule consisting of c and h atoms and one o atom only
Intermolecular forces are the forces that exist between molecules. These forces are responsible for the interactions between molecules, and they determine the physical and chemical properties of matter. Without intermolecular forces, matter would not exist as we know it.
Intermolecular forces are classified into four main types: dispersion forces, dipole-dipole forces, hydrogen bonding, and ion-dipole forces. Dispersion forces are the weakest of the four, but they are also the most common. Dispersion forces exist between all molecules, and they are responsible for the forces of attraction between molecules. Dipole-dipole forces are slightly stronger than dispersion forces, and they exist between molecules that have dipoles. Hydrogen bonding is the strongest of the intermolecular forces, and it exists between molecules that have hydrogen atoms bonded to nitrogen or oxygen atoms. Ion-dipole forces are the strongest of the intermolecular forces, and they exist between molecules that have an ionic charge.
Intermolecular forces are important because they determine the physical and chemical properties of matter. Without these forces, matter would not exist as we know it.

what quantity of 65 per cent acid solution must be mixed with a 20 per cent solution to produce 450 ml of a 50 per cent solution?
The answer is you will need 300 ml of 65% solution and 150 ml of 20% solution to produce 450 ml of a 50 per cent solution.
According to the question:
Start by defining variables to represent the amounts of each of the solutions that are going to be mixed.
So let x = the amount of the 65% solution, and y = the amount of the 20% solution.
First of all, you know that x + y = 450, because after they are mixed you want to have 450 ml of the 50% solution.
Second, look at how much acid is in each of the starting solutions and how much is in the ending solution.
The 65% solution is 65% acid, so the amount of acid in it is 65% of x, or .65x. Similarly, the amount of acid in the 20%
solution is 0.2y
At the end, the amount of acid you want to end up with is 50% of 450ml, so that's 225 ml.
When you mix the two solutions, you're not going to change the total amount of acid you started with. This means that
0.65x + 0.2y = 225
So, you have two solutions with two unknowns, and that's something you can solve:
x + y = 450
0.65x + 0.2y = 225
Let's use elimination. Multiply the first equation through by 0.65:
0.65x + 0.65y = 0.65*450 = 292.5
Now you have:
0.65x + 0.65y = 292.5
0.65x + 0.2y = 225
Subtract:
0.45y = 67.5
Divide by 0.45
y = 67.5 / 0.45 = 150
Since x + y = 450, that means that x = 300.
So, you will need 300 ml of 65% solution and 150 ml of 20% solution to produce 450 ml of a 50 per cent solution.

which of the following correctly explains why car tires may appear more deflated in winter than in summer? A) Atmospheric pressure outside is higher as colder air moves in during winter. B) As temperature decreases, the gas particles inside the tire move slower, collide less frequently with the walls of your tire's inner tube, and exhibit a lower pressure. C) As temperature decreases, the gas particles inside the tire move faster, collide more frequently with the walls of your tire's inner tube, and exhibit a lower pressure. D) The humidity in the air inside the tires decreases as temperatures approach freezing; below freezing, the volume occupied by the water vapor is lost when ice microcrystals form
The air compresses as it cools. Additionally, fewer molecules travel around in colder air. Less pressure will be applied to the tire walls by the air molecules. As a result, your tires appear to be flat.
Why do tires on cars lose air in the winter?Many drivers will notice a low-pressure warning light on their dashboard as winter approaches, or they may just notice that their tires don't appear to be quite as full as they should. The temperature decline is primarily to blame for this since colder air is denser and requires less tire pressure.
Why do vehicle tires lose pressure?In the winter, your tires lose air for the same physiological reason that medical professionals advise you to apply ice to an injury: cold temperatures promote contraction.

A mailing list or a marketing database is not used for this purpose. Rather fully detailed research analytics into the insight is used. Hence, the statement is false.

What hypothesis did the Miller-Urey experiment support?.
The Miller-Urey experiment provides evidence that the nucleotide base adenine can be created by combining hydrogen cyanide and ammonia in water. Many further experiments were sparked by this one.
Joan Oro discovered in 1961 that mixing ammonia and hydrogen cyanide in water might produce the nucleotide base adenine. His work resulted in a significant amount of adenine, whose molecules were created from 5 molecules of HCN. Additionally, under these circumstances, a large number of ammonia atoms is produced from HCN and ammonia.
The chemical compound hydrogen cyanide, often known as prussic acid, has the formula HCN. It boils just a little bit over room temperature and is a colourless, incredibly deadly, combustible liquid.

Dr. Metallica wants to change the property of an alloy? How could she do this?
She could do any of the above.
She could change the metal(s) used in the alloy.
She could change the nonmetal (s) used in the alloy.
She could change the percentages of the elements used in the alloy.
Dr. Metallica can change the property of an alloy by changing metal or non metal and their respective percentage in alloy.
The meaning of an alloy is a material created by combining two or more metals. Additionally, alloys can be created by combining metals with other elements. Alloys frequently display characteristics that vary greatly from those of their constituent parts. It is usual for alloys to be harder and stronger than pure metals. Copper and zinc are two metals that are mixed to make brass. A metallic element (iron) and a trace amount (up to 2%) of a non-metallic element are alloyed to form steel (carbon). Copper and tin are combined to make bronze. It is frequently used in medals, coins, trophies, heavy tools, electrical components, and gears. Bronze typically contains copper (Cu) in the range of 75% and tin (Sn) up to 12%.
Hence, property of alloy can be changed through constituent element and their percentage.
