Answer:

Porque las moléculas de glucosa son salvajes

Explanation:

Answer:

Glucose cannot move across a cell membrane via simple diffusion because it is simple large and is directly rejected by the hydrophobic tails. Instead it passes across via facilitated diffusion which involves molecules moving through the membrane by passing through channel proteins.

Answer:

3.077 × 10¹⁴ Hz

Explanation:

f = ?

wavelength = 9.75 × 10-⁷m

using the formula,

c = wavelength × frequency

f = c/wavelength

but c(speed of light) = 3×10⁸m/s

f = 3 × 10⁸/9.75 × 10-⁷

f = 3.077 × 10¹⁴ s-¹

The acceleration on an object is proportional to the resultant force and inversely proportional to the mass of the object  

Newton's 2nd law explains that the acceleration produced by the resultant force on an object is proportional and in line with the resultant force and inversely proportional to the mass of the object  

∑F = m. a  

[tex]\large {\boxed {\bold {a = \frac {\sum F} {m}}}[/tex]

F = force, N  

m = mass = kg  

a = acceleration due to gravity, m / s²  

Newton's equation shows that the greater the net force applied to an object, the greater the acceleration, conversely the greater the mass of the object, the smaller the object's acceleration.

Remember to convert Celsius values to Kelvin whenever you are dealing with gas problems. This can be done by adding 273 to whatever value in Celsius you have.

Normally in these types of problems (gas law problems), you are given all the variables but one to solve. In this case, the full setup would look like this:

Dividing both sides by 291 to isolate

In my school, we learnt that we use the Kelvin value in temperature to count significant figures, so in this case, the answer should have 3 sigfigs.

Answer:

It occurs when a gas passes through a tiny hole.

Explanation:

Effusion is a term used to describe when a gaseous molecule in a container passes or escapes through a tiny/small hole. Effusion and diffusion are two properties of gases that are often used interchangeably, however, they differ.

Effusion differs from diffusion in the sense that the gas passes through a TINY HOLE that is smaller than the normal path. This is contrary to when gas disperses throughout a container as in diffusion.

The correct answer is:

A) It occurs when a gas passes through a tiny hole.

Answer: A. The s orbital is lower in energy than the p orbital

Explanation: Just did test

The S-Orbital fill before the p-orbital Because, The s-orbital is lower in energy than the p-orbital. Hence, Option (A) is correct.

The aufbau principle, from the German Aufbauprinzip, also called the aufbau rule, states that in the ground state of an atom or ion, electrons fill subshells of the lowest available energy, then they fill subshells of higher energy.

For example, the S subshell is filled before the P subshell is occupied.

Therefore, The S-Orbital fill before the p-orbital Because, The s-orbital is lower in energy than the p-orbital. Hence, Option (A) is correct.

The second choice and the fourth choice are both based on science fact. The others are examples of pseudoscience.

Answer:

A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons. An element is a substance that is made entirely from one type of atom. For example, the element hydrogen is made from atoms containing just one proton and one electron.

Explanation:

Answer:

10 kg of ice will require more energy than the released when 1 kg of water is frozen because the heat of phase transition increases as the mass increases.

Explanation:

Hello!

In this case, since the melting phase transition occurs when the solid goes to liquid and the freezing one when the liquid goes to solid, we can infer that melting is a process which requires energy to separate the molecules and freezing is a process that releases energy to gather the molecules.

Moreover, since the required energy to melt 1 g of ice is 334 J and the released energy when 1 g of water is frozen to ice is the same 334 J, if we want to melt 10 kg of ice, a higher amount of energy well be required in comparison to the released energy when 1 kg of water freezes, which is about 334000 J for the melting of those 10 kg of ice and only 334 J for the freezing of that 1 kg of water.

Answer:

Im a 100% sure it is B. average molecular speed of ethane is greater than the average molecular speed of propanol.

Explanation:

Sry I didnt' get the explaination from my teacher.

According to the Kinetic theory of gases, the average speed of all gases at the same temperature will be in the same range. Hence, option C is correct.

Kinetic theory of gases states the properties and composition of gases at a temperature and pressure. According to this theory, gaseous substances are made of tiny particles which are free to move and collide to each other.

The kinetic energy of the particles is directly proportional to the temperature. Hence, as the temperature increases, the kinetic energy increases and their average molecular speed increases.

At the same temperature, all the gases have equal range of average molecular speed irrespective of their molecular weight. Hence, at 400 K the average molecular speed of ethane and propanol will be the same.

Tin(II) sulfate (SnSO4) is a chemical compound. It is a white solid that can absorb enough moisture from the air to become fully dissolved, forming an aqueous solution; this property is known as deliquescence. It can be prepared by a displacement reaction between metallic tin and copper(II) sulfate:[4]

Sn (s) + CuSO4 (aq) → Cu (s) + SnSO4 (aq)

Tin(II) sulfate is a convenient source of tin(II) ions uncontaminated by tin(IV) species.
