The reason why 1-hydroxy-2-methyl-5-isopropylbenzene is not the correct systematic name for carvacrol is because the substituents are not listed alphabetically.
IUPAC nomenclature provides the correct and acceptable system of naming organic compounds which are internationally acceptable among scientists.
According to the rules of IUPAC nomenclature, compounds are named in alphabetical order. The names of the locants are ordered in such a way that they have the lowest number. Following IUPAC nomenclature, the correct name of the compound ought to be, 1-hydroxy-5-isopropyl-2-methylbenzene.

Answer:
a) 2Ba + O2 → 2BaO
b) 2HCl + Mg → MgCl2 + H2
c) 2HCl + CuO → CuCl2 + H2O
d) Fe + O2 → Fe2O3
Explanation:
Okay so for
a), you must add 2 at the front of Ba and BaO bcuz you're gonna need your equation balanced.
like as you can see, O has 2 so yeahh, you've got to balance it nicely.
b) you must add 2 in front of HCl bcuz the Cl and H after the reaction happened has 2 in them, were talking about balancing so XD
c) and yes again, you're gonna have to add 2 in front of HCl bcuz of the same reason as b).
d) D is definitely a special case bcuz, Fe3+ with O2, so well if you do the cross multiplication technique you'll automatically get Fe2O3. Yas that's it.

Answer:
Rules for naming simple covalent compounds:
1. Name the non-metal furthest to the left on the periodic table by its elemental name.

Explanation:
The green light emitted by a stoplight has a wavelength of 505 nm. What is the frequency of this photon? (c = 3.00 × 10⁸ m/s).
Answer:
5.9405*10^14 Hz
Explanation:
Remember the equation c=v*λ
v=frequency
λ=wavelength
By manipulating the equation, we can get it in terms of frequency:
c/λ=v
Now convert wavelength to meters (1nm=m*10^-9)
5.05*10^-7m (2 decimal places were shifted to make the number between 1-10, hence the -7 exponent)
Use the manipulated equation:
(3.00*10^8)/(5.05*10^-7), which yields:
5.9405*10^14 Hz (or s^-1)
The frequency of the photon will be "[tex]5.9405\times 10^{14} \ Hz[/tex]".
According to the question,
Wavelength,
[tex]\lambda = 505 \ nm[/tex]or,
[tex]= 5.05\times 10^{-7} \ m[/tex]
As we know the equation,
→ [tex]c = v\times \lambda[/tex]
or,
→ [tex]v = \frac{c}{\lambda}[/tex]
By putting the values, we get
[tex]= \frac{3.00\times 10^8}{5.05\times 10^{-7}}[/tex]
[tex]= 5.9405\times 10^{14} \ Hz[/tex]
Thus the above answer is right.

calculate the mass in grams of two cubic inches (2.00 in³)" of gold. density of gold =19.3 g cm-.³
Taking into account the definition of density, the mass of two cubic inches (2.00 in³) of gold is 632.54 grams.
But first you must know the definition of density. Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.
In other words, density is a scalar quantity referring to the amount of mass in a given volume of a substance, that is, it shows the relationship between the weight (mass) of a substance and the volume it occupies.
Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
[tex]density=\frac{mass}{volume}[/tex]
In this case, you know that:
Density= 19.3 g/cm³ Volume= 2 in³= 32.7741 cm³ (being 1 in³= 16.3871 cm³)Replacing in the definition of density:
[tex]19.3\frac{g}{cm^{3} } =\frac{mass}{32.7741 cm^{3} }[/tex]
Solving:
mass= 19.3 [tex]\frac{g}{cm^{3} }[/tex]× 32.7741 cm³
mass= 632.54 g
In summary, the mass of two cubic inches (2.00 in³) of gold is 632.54 grams.

On vacation, Aria went scuba diving in the Pacific Ocean for the very first time. She rose toward the surface of the water at a steady speed for 4 minutes. She rose 36 meters in that time. What was her speed? HELP ME ASAP!!!!!!!!!!!!!
Aria speed during scuba diving was 0.15 m/s.
Speed is the ratio of the distance travelled to the time taken. Speed is given by:
Speed = distance / time
Given that the distance travelled was 36 meters and the time was 4 minutes, hence:
Time = 4 minutes × 60 seconds per minute = 240 seconds
Speed = 36 m / 240 s
Speed = 0.15 m/s
Therefore Aria speed during scuba diving was 0.15 m/s.

Explain why the element of an atom doesn't change if you remove or add electrons or neutrons
Answer:
If you could miraculously remove two neutrons from an atom's nucleus, the atomic number and electrical charge would stay unaltered. Because neutrons have no electrical charge, adding or removing them from the nucleus has no effect on the nucleus's electrical charge. It does, however, alter the nucleus's mass. Isotopes are formed by adding or subtracting neutrons from the nucleus.

Explain the process of ionization in at least 1 paragraph.
Brainliest goes to best explanation!
Explanation:
Ionization is the process by which ions are formed by gain or loss of an electron from an atom or molecule. If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it becomes positively charged (a cation). Energy may be lost or gained in the formation of an ion.

Refer to the observations of the test tubes from part A. Determine which metal (or hydrogen) in each test tube is
more reactive. Remember that the less reactive metal (or hydrogen) will typically end up in pure form as an
element, so no reaction will occur if the less reactive metal (or hydrogen) is the one that begins in pure form
Answer:
More Reactive:
iron
hydrogen
zinc
magnesium
zinc
iron
Explanation:
The reactivity of metals can be determined based on their ability to displace other metals from their compounds or to displace hydrogen from acids. Generally, metals that are higher in the reactivity series can displace metals lower in the series.
1. **Iron & Copper:** Iron is more reactive than copper. If iron is present in its pure form, it would displace copper from its compound.
2. **Copper & Hydrogen:** Hydrogen is less reactive than copper. No reaction will occur if hydrogen is the element in pure form.
3. **Zinc & Iron:** Zinc is more reactive than iron. If zinc is present in its pure form, it would displace iron from its compound.
4. **Iron & Magnesium:** Magnesium is more reactive than iron. If magnesium is present in its pure form, it would displace iron from its compound.
5. **Zinc & Hydrogen:** Hydrogen is less reactive than zinc. No reaction will occur if hydrogen is the element in pure form.
6. **Iron & Hydrogen:** Hydrogen is less reactive than iron. No reaction will occur if hydrogen is the element in pure form.
Remember, the reactivity series is a ranking of metals based on their tendency to lose electrons and form positive ions. Elements higher in the series can displace elements lower in the series from their compounds in certain reactions.
