Sample Response: No, thermal energy is not being transferred by radiation in this image. The eggs are in direct contact with the metal pan, which is in direct contact with the gas flame, so this is conduction, not radiation. Radiation transfers thermal energy by electromagnetic waves, not by direct contact.
Explanation:
No, thermal energy is not being transferred by radiation in this image.
The eggs are in direct contact with the metal pan, which is in direct contact with the gas flame.
Thermal energy is being transferred by conduction.
Radiation transfers thermal energy by electromagnetic waves.
Radiation does not transfer thermal energy by direct contact.
Thermal energy is the heat energy that is produced with an increase in temperature. No, thermal energy is not transferred by radiation when eggs are cooked.
What is radiation?Radiation is the process of thermal energy transfer that emits heat in all directions and does not require an intervening medium to travel.
Thermal energy is not transferred by radiation in the image as the eggs are in contact with the pan and the pan is in direct contact with a flame that radiates the heat by conduction.
Therefore, heat transfers by conduction and not by radiation.

How do I know the number of molecules in a equation
Answer:
Calculate he number of moles you have by taking the Mass / molar mass. if you have 1000 grams ; then 1,000 g / 151.001 g/mol = X g moles. Then multiply by Avogadros # = 6.022140857 × 10^23 molecules per g mole. The result is the # of molecules of MnSO4.

Jacob walked into a shop to buy cups for his house. He saw the cups shown below. Why does the cup on the right appear yellow? A. The cup absorbs yellow light but reflects all other colors of light. B. The cup reflects yellow light but refracts all other colors of light. C. The cup refracts yellow light but absorbs all other colors of light. D. The cup reflects yellow light but absorbs all other colors of light.
Answer:
D. The cup reflects yellow light but absorbs all other colors of light.
Explanation:
The cup in the shop appears yellow because the cup reflects yellow light but absorbs all colors of light.
Due to the materials the cup is made of, it is able to specifically reflect yellow and absorb other radiation types.
The color we see are products of the part of visible radiations they reflect.
The cup in this instance reflects yellow and absorbs other color.

Answer:
6
Explanation:
which type of cell is shown in the diagram - a plant cell, a yeast cell or a bacterial cell
Answer:
bacterial cell plant cells dont have a tail
Explanation:
The type of cell shown in the diagram is the bacterial cell as plant cell do not have tails while bacteria have tail.
Bacteria are prokaryotic unicellular organisms. They have a relatively simple cell structure compared to eukaryotic cells. They also do not possess any membrane-bound organelles such as a nucleus. However, do they possess genetic material (DNA or RNA) in the intracellular space called the nucleoid.
Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes. Prokaryotes are the dominant living creatures on Earth, having been present for perhaps three-quarters of Earth history and having adapted to almost all available ecological habitats.

Explanation:
What is the molar mass of Al(NO3)3 · 3H2O?
Answer:
Go to your periodic table and look for each element. Find the mass for Aluminum, Nitrogen, Oxygen, and Hydrogen.
After you find those, for each compound you must add them together and find the least amount of sig figs after the decimal point.
For the first compound, Al(NO3)3, you will have a total of
1 Aluminum atom
3 Nitrogen atoms
9 Oxygen atoms
Aluminum has 26.982 g/mol
Nitrogen has 14.007 g/mol
Oxygen has 15.999 g/mol
Now multiply those numbers by the amount of atoms of each element.
(1)26.982 g/mol = 26.982 g/mol
(3)14.007 g/mol = 42.021 g/mol
(9)15.999 g/mol = 143.991 g/mol
now add all of those numbers together, and you see that their least significant figure after the decimal is 3, so round to 3 digits after the decimal point.
26.983 + 42.021 + 143.991 = 212.994
now do the same for the other compound
to start you off.. you have
6 Hydrogen atoms
3 Oxygen atoms
Hydrogen has 1.009 g/mol
Oxygen has 15.999 g/mol
the least significant figure after the decimal point is 3, so round you 3 digits after the decimal point.
after you finish getting your totals, you. until them and find the greatest sig fig over all. comment on this if you need further instruction :)

Isotopes of the same element must have the same
A. atomic number
B. mass number
C. number of nucleons
D. number of neutrons
Answer:
D. number of neutrons
Explanation:
Isotopes of the same element must have the same number of neutrons. Neutrons of an atom are the uncharged particles within the nucleus.
Isotopy is the existence of two or more atoms of the same element having the same atomic number but having different mass number due to the differences in the number of neutrons in their various nuclei.
Therefore, isotopes differs based on the number of neutrons they contain.
Answer:
D. number of neutrons
Explanation:
Two isotopes of the same element have the same number of protons in the nucleus, but differ in the number of neutrons. The nucleon number is equal to the total number of protons and neutrons in the nucleus. ... The atomic mass number A is equal to the total number of protons and neutrons.

How many moles of S2 are needed to produce 1.50 moles of SO2 gas
Answer:
1.5moles of S;
Explanation:
The reaction expression is given as:
S + O₂ → SO₂
Number of moles of SO₂ = 1.5moles
From the balanced reaction expression:
1 mole of SO₂ will be produced from 1 mole of S;
So; 1.5moles of SO₂ will produce 1.5moles of S;
The moles of S₂ needed to produce 1.50 moles of SO₂ gas is 1.5 mol.
What are moles?The mole is a SI unit of measurement that is used to calculate the quantity of any substance.
The reaction is
S + O₂ → SO₂
The number of moles of SO₂ is 1.50 mol
1 mole of S produce 1 mole of SO₂
Then, 1.5 mole of S will produce 1.5 SO₂
Thus, the moles are 1.5.
