The condensation of a carboxylic acid with a sulfhydryl group will produce a thioester linkage.
What type of linkage is formed when a carboxylic acid reacts with a sulfhydryl group?When a carboxylic acid and a sulfhydryl group (containing a thiol functional group) undergo a condensation reaction, a thioester linkage is formed. This linkage involves the substitution of the hydroxyl group (-OH) of the carboxylic acid with the sulfhydryl group (-SH), resulting in the formation of a new carbon-sulfur bond.
Thioesters are important compounds in various biochemical processes and can be found in key molecules such as acetyl-CoA and fatty acid derivatives. They are involved in reactions such as fatty acid synthesis and protein modification.

20.What do carbon and silicon have in common?
a.They belong to the same column (family), therefore they have the same number of valence electrons.
b.They belong to the same column (family), therefore they have the same number of total electrons.
c.They belong to the same column (family), therefore they have the same number of energy levels.
d.They belong to the same column (family), therefore they have the samenumber of protons.
The carbon and silicon have in common that they belong to the same column (family), therefore they have the same number of total electrons. So, option B is correct.
What do carbon and silicon have in common?Carbon's closest analogue is silicon. Silicon and carbon are both tetravalent atoms that primarily form covalent (non-ionic) compounds. However, aside from the fact that both elements "can form four covalent bonds," there is surprisingly little in common between them.
Carbon has an atomic number of 6 and an electronic configuration of 2, 4. Silicon has an atomic number of 14 and an electronic configuration of 2, 8, 4. Because both elements have the same number of valence electrons, they are classified as being in the same group.
Thus, option B is correct.

Explanation:
Each element... A. Has only one kind of atom B. Has only one kind of molecule C. Is made of rock D. All of the above
Answer:
A. Has only one kind of atom
Explanation:
All forms of matter are composed of elements.
An element is a substance which cannot be broken down into simpler units or converted into other substances by ordinary chemical reactions. Each element is composed of only one kind of atoms which are unique to each element. There are three fundamental sub-particles present in atoms of elements; these are: protons, electrons and neutrons. An atom of an element differs from an atom of another element by its atomic number. The atomic number of an element is the number of protons present in the nucleus of the atom of that element. For example, hydrogen atoms has an atomic number of 1, while sodium atoms has an atomic umber of 11.
Atoms of the same element or different elements may combine together to form the molecules of a substance. For example, a molecule of hydrogen gas is made up of two atoms of hydrogen whereas a molecule of water is composed of two atoms of hydrogen and an atom of oxygen.
Elements can exist in any of the three physical states: solids, liquids or gases. For example, hydrogen exists as gas, mercury as a liquid, while gold exists as a solid.

Given the following equation: Na2O + H20 - 2 NaOH
How many grams of Na20 are required to produce 1.60 x 102
grams of NaOH?
g
Answer:
124g
Explanation:
The concept stoichiometry is used here to determine the mass of Na₂O. The grams of Na₂O required to produce 1.60 x 10² grams of NaOH is 124 g.
What is Stoichiometry?The stoichiometry is an important concept of chemistry which help us to use the balanced chemical equation to calculate the amounts of reactants and products. The stoichiometric coefficient is the number of molecules that can participate in the reaction.
The balanced equation is:
Na₂O + H₂O → 2NaOH
1 mole of Na₂O is required to react with 1 mole of H₂O to give 2 moles of NaOH.
62 g of Na₂O produces 80 g of NaOH.
1 g of NaOH is produced from 62/80 g of Na₂O .
1.6 × 10² g of NaOH will require 62 × 1.6 × 10² g / 80 g of Na₂O = 124 g Na₂O
Thus the grams of Na₂O required to produce 1.6 × 10² g of NaOH is 124 g.

If 3.68 grams of zinc were allowed to react with excess hydrochloric acid to produce zinc chloride and hydrogen gas, how much zinc chloride should be produced?
Suppose that 7.12 grams of zinc chloride is actually recovered, what is the per cent yield?
Answer:
Here... Since there is excess HCl, you know the Zinc will be the limiting reagent. I was able to create the reaction equation based on the info you gave: Z + 2HCl ----> ZCl2 +2H. Now, in order to find the theoretical yield of ZCl, you need to convert Zinc from grams to moles. Do this by dividing by its molar mass (65.38), thus: 3.68 (g) / 65.38 (g/mol) = 0.056286... moles.
Now, using the balanced equation we made earlier, we see that 1 mole of Zinc creates 1 mole of ZCl2. Thus our ratio is 1:1. This makes the next step easy. Since it is 1:1, we multiply the number of moles we have of Zinc (0.056286...) by the number of moles it will create of ZCl (1). (0.056286)(1) = 0.056286 moles ZCl. Now convert this to grams by multiplying by its molar mass (136.28) and you get 7.67 grams. This is your theoretical yield. The percent yield is found by dividing the actual amount obtained (7.12 g.) by the theoretical yield (7.67 g.) then multiply that by 100%. When this is done, your Percent Yield is about 92.8%

Explanation:

Shear adhesion sticks best when it is pulled down parallel to the surface.
What is shear adhesion?Shear adhesion is defined as the ability of tape due to which it resists the static forces which are applied in same plane as in backing.It is usually expressed in terms of time required by a given weight for an amount of tape to become loose from a vertical plane.
Molecular weight between two entanglements is the controlling factor of shear adhesion. Shear adhesion is affected by the following parameters which areas follows:
1)Tg of adhesive - Shear adhesion increases as Tg rises up to a certain temperature which is less than the room temperature.
2) Tan delta minimum value of adhesive- It is found that shear adhesion improves by an increase in tan delta minimum value.
3)Adhesive polarity- It is an important factor which affects adhesion such as tack,peel and shear.Adhesion performances are improved by introducing polar ingredients in the formulation.

Oxygen has 8 positively charged protons what is the number of negatively charged electrons in an atom of oxygen?
Answer:
8 electrons (e-)
Explanation:
In the atom of every elements, there are three sub-atomic particles namely: protons, electrons, and neutrons. The protons are the positively charged particles, the electrons are negatively charged while the neutrons are neutrally charged.
In an uncharged or neutral atom i.e. charge 0, the number of protons is always equal to the number of electrons because they cancel each other out. When a difference occurs in the number of these particles, the atom becomes charged i.e. an ion. According to this question, oxygen atom (O) contains 8 positively charged protons, this means that it also contains 8 negatively charged electrons in its atom.

Collision of which two types of plates create the deepest earthquakes? Why do you think this is?
Answer:
The collision of oceanic plates and any other plates in which the oceanic plate slides beneath the other plate creates the biggest earth quakes. Most of these earth quakes occur beneath the sea or oceans and can cause volcanic eruptions as well. Tsunami is another oceanic event that occurs due to earth quakes occurring due to shifting of plates beneath the sea.
is there a relationship between the relative age of stars in the number/identity of element is found within them
Yes. Stars use fusion to create nuclear energy, which is what makes them "alive". The older they are, the "bigger" the element in them is. Hydrogen turns into Helium, and when hydrogen is used up, the helium starts fusing into bigger elements. it stops at iron however. Once stars start fusing silicon to iron, it is doomed because it takes more energy than it gives off.
