what is the mass of 3.0 x x times 10^23 atoms of neon?
Answer:
10.09 grams
Explanation:
First you need to know the number of moles you are dealing with.
If you know that each mole has 6.022x10²³ of something (in this case of atoms), you can divide 3x10²³ atoms of neons by 6.022x10²³ to obtain the number of moles.
You have 0.5 moles of Neon, so then by the periodic table, you see that the molar mass of neon is 20.18g/mol, so by each mole you have 20.18 grams of neon. Multiply 20.18 grams by 0.5 moles and you got 10.09 grams of Neon

A student measures the acidity of a solution and
concludes that it has a pH of 2.70. However, the
seller claims that its pH is 3.20. What is the
percent error in the student's measurement?
Answer:
15.63%
Explanation:
The formula of error percentage is:
([experimental value-real value]/real value)100%
You divide the subtraction of the absolute value of experimental value (the one you got during a experiment) and the one that's "proven" to be right by again, the proven value. You got a decimal and all you have to do is multiply it by 100%

How is the polarity of a bond different from the polarity of a molecule?
Answer:
A polar bond is one where the charge distribution between the two atoms in the bond is unequal. A polar molecule is one where the charge distribution around the molecule is not symmetric. It results from having polar bonds and also a molecular structure where the bond polarities do not cancel.

Which of the following liquids has the highest viscosity
A water
B oil
C milk
D honey
Answer:
honey has the highest viscosity
According to the given option, honey is the liquid that has the highest viscosity. So, the correct option is D.
What do you mean by Viscosity?Viscosity may be defined as the effects of a liquid by probity of which an internal resistance comes into play when the liquid is in movement and resists the comparable motion between its distinct layers.
Among all the given options, honey possesses more strong intermolecular attractive forces that result in the high compaction of particles in the honey.
After honey, Oil is more viscous followed by milk, and then water.
Therefore, the correct option for this question is D.

The ribosomes of plant cells are sites for the synthesis of
(a) ATP (b) nucleic acids (c) sugars (d) proteins
Answer:
Proteins
Explanation:
Their Function Formation Encoded in mRNA into polypeptide chains of amino acids that produces protein
The ribosome of plant cells are sites for the synthesis of proteins. The correct option is (d).
What are ribosomes?Ribosomes are organelles that take part in the synthesis of proteins. The prokaryotic cell's ribosomes are smaller than the eukaryotic cell's ribosomes.
Currently, ribosomal RNA is a component of the cell's ribosome or protein-building machinery. The process of making proteins, or translation, is carried out by ribosomes.
The ribosome, which translates the genetic code generated in mRNA into an amino acid sequence, is universally responsible for protein synthesis. The two ribosomal subunits, small and big, come together to form the full ribosome, which is used to produce proteins.
Therefore, the correct option is (d) proteins.

If the energy of the H–H bond is 452 kJ/mol. The energy of the O=O bond is 598 kJ/mol. The energy of the O–H bond is 367 kJ/mol, which bond would be the strongest? Which bond would be the weakest?
Taking into account the bond energy, the O=O bond is the strongest and the O–H bond is the weakest.
The bond energy is the average total energy that would be released by the formation of a mole of chemical bonds, from their constituent fragments (all in the gaseous state).
In other words, the normal or standard bond enthalpy is defined as the change in enthalpy or heat released, under standard conditions of 1 atmosphere and 25ºC, that accompanies the reaction of formation of one mole of bonds from the isolated atoms in gaseous state.
The higher the bond energy, the stronger and more stable the bond will be.
So, taking into account all the previous, the O=O bond is the strongest and the O–H bond is the weakest.
