Mole ratio compares the subscripts of two compounds in a balanced reaction.
(1 Point)
TRUE
FALSE
Answer:
The correct option is FALSE
Explanation:
Mole ratio is the ratio of the number of moles of two compounds in a balanced chemical reaction. Number of moles of a compound in a chemical reaction is the number written before the compound.
For example, the mole ratio of Iron (Fe) and water (H₂O) in the equation below is 3:4
3Fe + 4H₂O ⇒ Fe₃O₄ + 4H₂
Thus, mole ratio does not compare subscripts of compounds.
Why do you think it might be useful to know the distance between a gun fired and its target? (Forensics)
Answer:
Yes, because in situations where an individual has been shot, it may be helpful for investigators to know how far away the shooter was from the victim. For example, in some cases a defendant accused of murderr may say that the shooting happened in self-defence. The actual distance between the two individuals may indicate whether the defendant is telling the truth. Similarly, knowing the approximate distance of a shot can help forensic scientists determine if a death was a suic ! de, or if it was a homic! de made to look like a suic! de.

The isotope 106 46Pd (106 on top and 46 on bottom)
has
1. 60 protons.
2. 106 neutrons.
3. 46 neutrons.
4. 60 neutrons.
Can I also have an explanation as well plz
Answer:
4. 60 neutrons.
Explanation:
The given isotopes;
¹⁰⁶₄₆Pd
In this isotope, we can deduce that the mass number is the superscript and the atomic number is the subscript;
Mass number = 106
Atomic number = 46
Mass number is the number of protons and neutrons in an atom;
Mass number = Protons + neutrons
Atomic number is the number of protons
So, Number of protons = 46
Number of neutrons = Mass number - Atomic number
= 106 - 46
= 60
Number of neutrons = 60
A molecule _____. is made of more than one atom is the same as a compound must be made of more than one element can only contain two atoms
Answer:
it is not an act answer but it has information
Explanation:
A molecule is defined as two or more atoms of the same element different element that are bound together. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (H2O).
A molecule is made up of two or more atoms, and it can be composed of atoms of the same element or different elements.
A molecule is a particle that consists of two or more atoms chemically bonded together. It is the smallest unit of a compound that retains the chemical properties of that compound.
Molecules can be composed of atoms of the same element or different elements. When atoms of the same element combine to form a molecule, it is called a diatomic molecule.
On the other hand, molecules can also be formed when atoms of different elements combine. In this case, the molecule is considered a compound. Compounds are composed of two or more different elements chemically bonded together.
Hence, a molecule is made up of two or more atoms, and it can be composed of atoms of the same element or different elements.

Two students are planning an investigation to determine if ionic or covalent bonds have stronger intermolecular. They are using salt (ionic), sugar (polar covalent), and moth balls (nonpolar covalent). Which one of the tests would not be relevant to their experiment?
Answer:
conductivity in water/ solid state
Explanation:
becuase, they both dissolve in water the same, therofre it is the least helpful.
The test that will be least helpful to determine if ionic or covalent bonds have stronger intermolecular is solubility in water. Therefore, option (B) is correct.
What is the covalent and ionic bond?The covalent bonds are formed by the shared pair of electrons between the atoms while the ionic bonds are formed by the complete transfer of electrons between the atoms. Methane is covalent while NaCl is an ionic compound.
Ionic compounds have strong intermolecular forces of attraction while covalent compounds don't. The covalent solids exhibit less melting point compared to the ionic compound.
Covalent compounds are generally more flammable than ionic solids. Salt conducts electricity in the water while sugar does not conduct electricity in the water.
As both students are trying to find the stronger intermolecular forces between ionic or covalent bonds, both salt and sugar are soluble in water. Therefore, the solubility in water would not be relevant to their experiment

Explanation:
Why are gamma rays not able to reflect off a mirrors surface
Answer:
the Ray's go right through it
Explanation:
the Ray's are so small they punch right through them
Answer:
Explanation:
The reason why is based in something called the plasma frequency of the metal of a mirror. A metal, as you may know, is composed of a series of atom (ion, effectively) cores - nuclei, together with some, but not all, of their bound electrons - which contribute the remaining outermost electrons of their unbound forms to a communally shared "electron sea" - kind of like a giant, distributed omnidirectional covalent bond that extends all throughout the whole metal crystal (here we're just considering a single crystal for simplicity). The electrons are quantumed out all over the full extent of the crystal and effectively form a sort of "gas" throughout and permeating the metal.
When an electromagnetic wave approaches that gas, the free charges within it - the electrons - start oscillating, and as they do so, they set up another wave going outward at the same time as the first is going in. This begins as soon as the first wave begins to impinge.
However, if the wave oscillation is fast enough, the electrons can't keep up due to their mass, and thus they are unable to form the reflected wave. The frequency at which this occurs is called the metal's plasma frequency (and is inversely proportional to the square root of the mass, so that a high mass particle would have a lower plasma frequency). The name comes from the fact that the metal can be thought of in a sense as a kind of "solid plasma" - ions with free electrons, the difference with what most people think of as a "plasma" being here the ions are not free to move about of their own accord.
is disilicon tetraoxide held together by a covalent or polar covalent?
Explanation:
The compound disilicon tetraoxide has the formula;
Si₂O₄;
This compound is held together by a polar covalent bond. A polar covalent bond occurs between two species that shares electrons. In this bond type, the more electronegative element draws the shared electrons more closer to itself.
Oxygen is more electronegative than silicon. It will draw the shared electrons more closer. This leaves a partial positive charge on the silicon and a negative charge on the oxygen.
