Dietary protein will not be digested if Hcl were not being produced in sufficient quantities.
In the stomach, there are some glands found on the stomach lining that helps to release hydrochloric acid (HCl). Their major role is to dissolve food and produce an acidic medium.
The acidic media promotes and improves the conversion of pepsinogen to pepsin. Pepsin acts as an enzyme that supports protein digestion.
Protein digestion requires a pH of around 1.8 which can be achieved by the secretion of HCl.
As a result, if HCI is not released in the stomach in sufficient quantities, pepsin will not be activated and it would have a detrimental impact on protein digestion.
Therefore, we can conclude that dietary protein will not be digested if Hcl were not being produced in sufficient quantities.

what quantities vary between isotopes of an element
The quantities that vary in the isotopes of the same element is number of nucleons and the number of neutrons.
Isotopes are atoms of the same element that have different numbers of neutrons. The number of protons and electrons in isotopes of an element remains the same because they determine the element's chemical properties.
Nucleons refers to the collective number of protons and the neutrons present inside the nucleus. Isotopes can have different physical properties due to the varying number of neutrons.
Therefore, the isotopes differ in the quantity of number of neutrons and the nucleons present.

3.5 mol/L
Explanation:
First convert the 139.9g of LiCl into moles of LiCl. Don't do the sig fig rule until the very end.
Second, take 930mL of LiCl and divide it by 1000 to convert it to liters.
Third use the molarity formula which is M=mol/L and divide 0.930L by 3.300773877mol and you will get 3.549219223. This is where the sig fig rule will come into play. 3.5mol/L is a reasonable answer for this problem.

Is this equation balanced? Explain why the equation S+3O2 → SO3 is balanced or is not balanced. Use four different words from the word bank to earn (4 points).
We can check if the equation is balanced by comparing the number of atoms of each element on the reactant and product sides. The reaction is only balanced if the number of atoms of each element is equal.
S + 3O₂ → SO₃
Reactant Product
S 1 1

based on the activity series, which metal dissolves in hydrochloric acid to produce hydrogen gas, but does not react with steam or liquid water?
Answer: Iron
Explanation: does not react with water, but hydrochloric acid will dissolve them, displacing the hydrogen from the HCl. Iron reacts with hydrogen chloride to produce iron chloride, FeCl2 — sometimes known as ferrous chloride.
To solve such this we must know the concept of chemical reaction. Iron is the metal, which dissolves in hydrochloric acid to produce hydrogen gas, but does not react with steam.
What is chemical reaction?Chemical reaction is a process in which two or more than two molecules collide in right orientation and energy to form a new chemical compound. The mass of the overall reaction should be conserved. There are so many types of chemical reaction reaction like combination reaction, double displacement reaction.
When metals react with acid the liberation of hydrogen gas take place. Metal which is at top of reactivity series react with both acid and steam or liquid water. Iron is the only metals which dissolves in hydrochloric acid to produce hydrogen gas, but does not react with steam or liquid water.
Therefore, iron is the metal, which dissolves in hydrochloric acid to produce hydrogen gas, but does not react with steam.

what is the molar mass of dimethylglyoxime, c4h8n2o2?
Explanation:
The molar mass of a compound can be calculated by finding the molar of the individual atoms that combine to make the compound.
Molar mass of compound =
∑ (molar mass of element × number of atoms of the element)
∴ Molar mass of dimethylglyoxime
= 4C + 8H + 2N + 2O
= [(4 × 12.011) + (8 × 1.0080) + (2 × 14.007) + (2 × 15.999)] g/mol
= 116.12 g/mol

Overlap of the electron clouds of two atoms results in a(n)
a hydrogen bond
b dipole
C ionic bond
d covalent bond
Check it
We know that the electron clouds of two atoms overlapping is a bond, because that signifies that the electrons are being shared in a bond.
So, I'm going to go through some definitions of these different types of bonds, because they have very specific circumstances.
A hydrogen bond is a bond between an electronegative atom and a hydrogen molecule (which is not what this question says, this isn't stated anywhere).
A dipole is a difference in electron density on two different atoms (so this isn't even close to what the question is stating, a dipole is not even a bond)
An ionic bond is an unequal sharing of electrons between two atoms (because the question doesn't state this specific fact, then it can't be this option).
By process of elimination, we know the answer is covalent bond, but just in case, we can also look at the definition of a covalent bond: a bond that involves the sharing of electrons between atoms.
That is exactly what the question is asking for! Therefore, your answer is d. covalent bond
