The solution of sugar at 60.0 degrees celcuis is 290.0 g/ 100 g water. If you add 100.0 g of sugar to 25 g of water at 60.0 degrees celcuis will the sugar dissolve?
Answer:
you will produce a saturated solution, At 0 degrees Celsius, sugar is claimed to dissolve 180 grams in 100 grams of water. This means that if you dissolve that much sugar in 100 g of water, you'll get a saturated solution.
Explanation:
The correct answer for the given question about Saturated solution is only 72.5 gram will get dissolved and rest which is 27.5 gram will remain undissolved.
How to apply concept of Saturated solution to solve this question?In question it is given that at 60° C 290 gram of sugar in 100 gram of water produce saturated solution.
So at 60° C 290/100 gram of sugar in 1 gram of water will produce saturated solution.
Hence we can say that at 60° C (290/100)×25 gram of sugar in 25 gram of water will produce saturated solution.
means at 60° C 72.5 gram of sugar in 25 gram of water will produce saturated solution.
Now, adding 100 gram of sugar in 25 gram of water.
Since you can only hope to dissolve 72.5 gram at 60°,
Hence the resulting solution will contain undissolved sugar.
So only 72.5 gram will get dissolved and rest which is 27.5 gram will remain undissolved.
Thus, We can conclude that Only 72.5 grams of sugar will dissolve, leaving the remaining sugar of 27.5 grams undissolved.

need answers to a and b !
thank you!
a) The genotype is Hh. We simply combine the two given letters together to get this genotype.
b) The phenotype is Widow's peak. The uppercase letter is the dominant allele, while the lowercase is recessive. Any presence of the dominant allele (even a single letter) will mean the dominant phenotype will present itself. We can see that HH leads to Widow's peak phenotype, so that applies to Hh as well. Only when there isn't a dominant allele at all, the genotype hh, is when the recessive phenotype will show up.

The diagram shows the breathing system in a human. What does label 1 show?
Answer:
parietal pleura
Explanation:
The pleurae, which are serous membranes, divide the thoracic cavity's wall from the lungs. The parietal pleura covers the interior of the thorax, mediastinum, and diaphragm, while the visceral pleura covers the surface of the lungs.
What is the function of parietal pleura?The perianal pleura, the outer layer, is attached to the chest wall. The lungs, mediastinum's neurovascular structures, and bronchi are all covered by the inner layer (visceral pleura).
The pleura's role in breathing is to enable the lungs to expand and collapse as efficiently as possible.
The parietal and visceral pleura can move over one another without rubbing against one another thanks to the pleural fluid's lubricating properties. The pleural layers themselves produce this fluid.
Therefore, parietal pleura, which surround the lungs in thoracic cavity.

Which coefficients correctly balance the formula equation below?
AgNO3 + CuCl2 → AgCl + Cu(NO3)2
2, 1, 2,1
1, 1, 3,1
2, 2, 3,1
2, 1, 1,2
Answer:
2, 1, 2,1
Explanation:
The chemical equation of the reaction given in this question is as follows:
AgNO3 + CuCl2 → AgCl + Cu(NO3)2
The reaction is between silver nitrate (AgNO3) and copper (I) chloride (CuCl2) to form silver chloride (AgCl) and copper nitrate (Cu(NO3)2.
However, this above equation is not BALANCED because the number of atoms of each element on both sides of the equation does not equate i.e. are not the same. To balance the equation, we have to make use of COEFFICIENTS, which are numbers used in front of each element in order to balance the equation.
The balanced equation is as follows:
2AgNO3 + CuCl2 → 2AgCl + Cu(NO3)2
From the above balanced equation, we can observe that coefficients used to balance the equation is in the order: 2, 1, 2,1

Explanation:
The can chiller has a cooling system which expels heat around the immediate vicinity of the can chiller.
Let us remember that convection is a mode of heat transfer that occurs as a result of the actual movement of the particles of a substance. In this case, we are going to consider the movement of air molecules.
As the can chiller expels heat, the air molecules around the can chiller become heated and less dense and begin to move away from the can chiller. They are quickly replaced by cold denser air.
This process of cycling of hot/cold air molecules is known as a convection current. It is set up as a result of the working of the can chiller.
Which statements about a phosphorus atom, P, are correct?
1. The nucleon number is 16.
2. The number of outer electrons is 5.
3. The proton number is 15.
Answer:
3. The proton number is 15.
Explanation:
Phosphorus, P is the element with the atomic number = 15. The atomic number = Number of protons. That means:
3. The proton number is 15.
Now, the number of protons = Number of electrons = 15.
And, nucleon number = Number of protons + number of neutrons. The must abundant phosphorus atom contains 16 neutrons and nucleon number is: 15+16 = 31.
Thus, we can know which statement is true.

What similarities are there between Beta Radiation and Alpha Radiation
The largest particle, Alpha, has the least penetrative power. Positive charge is carried by alpha particles. Two neutrons and two protons are bound together to form an alpha particle. The helium-4 nucleus was later identified as the alpha particle. Among the three types of radioactive emissions, alpha particles have the most mass. An alpha particle has approximately 8000 times the mass of a beta particle. The penetrative power of an alpha particle is reduced due to its large size.
Beta particles are negative-charged high-energy electrons or positrons. Beta particles have a higher penetrative power than alpha particles due to their smaller size.

how to determine the aspects for core and valence electrons in a periodic table. How comes in some elements like cobalt the 3d is on the valence side and arsenic the 3d is on the core side.
Answer:
See explanation
Explanation:
The electron configuration of an atom in an element determines the property of the atom. The core electrons are found inside the atom while the valence electrons are found on the outermost shell of the atom.
For cobalt, the outermost shell electron configuration is; [Ar] 3d7 4s2. The 3d7 and 4s2 are found in the valence shell of cobalt.
For arsenic, the electronic configuration is [Ar] 3d¹⁰ 4s² 4p³. The valence electrons are 4s2, 4p3. The 3d electrons are found inside the arsenic atom.
