Which bond pair does not have a polar covalent bond? P – Cl O – H S – Cl H – Cl Cl – Cl

So,

A polar covalent bond is a bond between two atoms that has a low electronegativity difference (usually 0.1 < x < 1.9, which is kind of the border between nonpolar covalent and ionic, respectively).  The most prominent example of a polar covalent bond is water, where the oxygen atom has an electronegativity of 3.5 and the hydrogen atoms have electronegativities of 2.1.  The electronegativity difference is 3.5-2.1 = 1.4, which is still in covalent territory, but still a polar bond.  This is why lowercase delta's appear beside oxygen atoms in drawings.

Examining, the four options, we immediately see that option D is Cl-Cl.  A bond between two of the same atoms inevitably implies an electronegativity difference of zero, which means a nonpolar covalent bond: electrons are equally shared.  Anywhere you see two identical atoms bonding (except for metals), you will have a nonpolar covalent bond.

The correct answer is D.

Business owners must consider the products mission statement, a unique brand, the timing, the packaging, promotion, the audience.
To create a product you first need a problem then a solution. So if the problem is that water bottles aren’t holding enough water, the solution would be to create bigger yet lighter water bottles.
Let’s say you are to create a water bottle that is sturdier than others and can hold more water but weigh less. You would first consider the target audience. People that exercise and are into fitness would find the product more useful. So many making changes to the product to better fit their needs will help. Next the promotion and timing . It would be best to release the product near New Years since that’s when most people go to gyms. This will allow your product to reach a greater target audience and have more sales. Also testing your bottle to make sure it’s up to what you’re proving and so on.

Which enzymes has the most significant effect on the chemical digestion of kool aid drink?
BartSMP [9]

Answer:

pancreatic amylase, lingual amylase, intestinal amylase

Explanation:

When considering a sugar drink, the enzymes involved in its digestion are first the alpha amylase found in saliva, responsible for degrading starch molecules, thus generating unique molecules of monosaccharides. Then the ones in charge of continuing with the digestion will be the pancreatic amylase and the intestine at the duodenal level.

Decide which element probably has a boiling point most and least similar to the boiling point of potassium.
larisa86 [58]

Explanation:

  • The boiling point of Potassium is most similar to the element sodium , since , both the elements belong to the same group i.e. , the group one , Hence , the most of the physical chemical properties are same , irrespective of some exceptions .

Hence , the Boiling point of Potassium and sodium are the same .

  • The boiling point of Potassium is least similar to the element helium , since , both the elements belong to different groups , Since , Helium has a negative boiling point and is one of the most stable element , being a noble gas .

The longer the reaction time is, the the reaction rate is. Reaction time is to reaction rate.
Nostrana [21]

Answer:

False.

Explanation:

Rate of reaction  also depends on the number of collision that is being happening in reacting molecules. So concentration of the reactants is also important to decide the rate of reaction.

The rate of reaction is dependent on the concentration as well.

As the concentration of reactants decreases with time number of collisions also decreases .
