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.

1. In drawing Lewis structures, a single line (single bond) between two elements represents: ? a shared electron B. ? B 2 a shared pair of electrons c. ? an octet of electrons D. ? an unshared pair of electrons
Answer:
B a shared pair of electrons (2)
Explanation:
In Lewis structures, a single line represents a single pair of electrons. This means that the elements share 2 electrons or one pair of electrons
Hope this helps!
The shared electrons behave as if they belong to both atoms in the bond and bind the two atoms together to form a molecule. The shared electrons are typically depicted as a line (—) connecting the bonded atoms. (A line in a Lewis structure represents two electrons. Therefore, option A is correct.
What is lewis structure ?Lewis structures, also known as Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures, are diagrams that depict the bonding between atoms in a molecule as well as any lone pairs of electrons that may exist.
A Lewis structure is based on the octet rule, which states that atoms share electrons in order for each atom to have eight electrons in its outer shell. An oxygen atom, for example, has six electrons in its outer shell.
Gilbert N. Lewis, who introduced the Lewis structure in his 1916 article The Atom and the Molecule, was named after it. Lewis structures expand on the electron dot diagram concept by adding lines between atoms to represent shared pairs.
Thus, option A is correct.

Which part of atomic structure is responsible for the reactivity of atoms?
The electrons present in the valence shell of an atom are responsible for the reactivity of atoms.
What is an atom?An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.
The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.
Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

Answer:
20.03g
Explanation:
This is the formula for percentage yield:
Percentage yield = Actual Yield / Theoretical yield
Rearrange it to get the Actual yield, which would be:
Actual yield = Percentage yield (in decimal form) x Theoretical yield
We know that 75% of CO2 is produced as the percentage yield in a reaction and the theoretical yield for the mass we're supposed to find is 26.7 grams.
Percentage yield in decimal form: 0.75
Theoretical yield: 26.7g
Plug it in the equation
Actual yield = 0.75 x 26.7g
Actual yield = 20.03g

as the atoms of the elements from atomic number 3 to 9 are considered in sequence from left to right on the periodic table, the atomic radius of each successive atom is
Answer:
decreasing
Explanation:
from left to right the nuclear effective charge is increasing, attracting with a greater force the electrons and making the atom to reduces itd atomic radius
The atomic radius decreases along a period in periodic table. Thus, from the third element Li to the 9th element fluorine, atomic radius decreases and F has the lowest radius among them.
What is atomic radius?Atomic radius is the distance from the nucleus to the valence shell. The atomic radius decreases from left to right in periodic table. Thus, the higher atomic radius is exhibited by metallic elements.
The horizontal rows in the periodic table is called periods. Along a period , atomic radius decreases and electronegativity increases. When moving to the right there is no increase in the number of shells and the filling of electrons does not achieve octet except for group 18. Hence, they are electronegative.
From atomic number 3 to 9 atomic number is decreasing. Hence, among these elements, the smallest one is fluorine (Z = 9).

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 particle diagram shown above best represents the strongest intermolecular force between two ethanol, c2h6o, molecules?
The strongest intermolecular bonding in ethanol is hydrogen bonding.
Intermolecular forces are the forces that hold two molecules of a substance together in a given state of matter. For ethanol, the strongest intermolecular force is hydrogen bonding.
Hydrogen bonding occurs when hydrogen is directly linked to a highly electronegative element such as oxygen, nitrogen, fluorine or sulfur. The existence of intermolecular hydrogen bonds accounts for unusual properties such as abnormally high melting and boiling points.

Would an alkaline earth metal make a good replacement for tin in a tin can?
Answer:
Definitely not. This is because the alkaline earth metal [basically group 2 elements] are reactive and will react with the contents of the can, contaminating it.
No, alkaline earth metals would not be a good replacement for tin in a tin can because alkali from alkaline earth metals react with tin and release hydrogen.
What are alkaline earth metals?Alkaline earth metals are present in group 2 of the periodic table. They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra).
They are called alkaline earth metals because their hydroxide and oxides are highly alkaline. Their metal oxides are found in the earth's crust.
These metals have 2 electrons in their outer shell, and they are highly reactive, so they will react with the tin in a tin can.
Thus, alkali from alkaline earth metals react with tin and generate hydrogen, hence they would not make an acceptable replacement for tin in a tin can.
