AlBr3 can be used as a catalyst in the Friedel-Crafts alkylation reaction. The correct name for the compound represented by the formula AlBr3 is —
aluminum bromide
monoaluminum tribromide
aluminide bromine
aluminum tribromide
Answer:
aluminum bromide
Explanation:
Having known that AlBr3 is an ionic compound and aluminium is the central atom here, we now have to ask ourselves if Aluminium exists in other stable oxidation states.
We must take cognizance of the fact that the oxidation number of the central atom in a compound becomes part of the name of that compound when other stable oxidation states for atoms of the same elements exists.
Since the +3 state is the only stable oxidation state for aluminium, the name of the compound is simply aluminium bromide.

Explanation:
Para preparar 1 kilogramo de arcilla se requieren 400 gramos de agua. Si a nivel del laboratorio solo se cuenta con una probeta y sabemos que la densidad del agua es 1100Kg/m3 ¿Cuántos litros de agua se deben añadir?
Answer:
0.364 L
Explanation:
Para resolver este problema es necesario expresar la densidad en g/L.
Para hacer esa conversión primero convertimos m³ en L:
1 m³ = 1000 L1100 [tex]\frac{kg}{m^3}* \frac{1m^3}{1000L}[/tex] = 1.1 kg/LY después convertimos kg en g:
1.1 kg/L * [tex]\frac{1000g}{1kg}[/tex]= 1100 g/LFinalmente dividimos la masa deseada (400 g) entre la densidad, para calcular el volumen:
400 g ÷ 1100 g/L = 0.364 LWhy is a synthetic gemstone (made by humans) not considered a mineral?

For complete combustion of an organic compound needs 8 molecules of oxygen, what could the formula of this compound be?
Answer:
C5H12.
Explanation:
The compound will be C5H12.
Now consider the general formula for the combustion of an alkane;
CnH2n+2 + 3n+1/2O2-----> nCO2 + (n+1) H2O
If we substitute n=5, we have;
C5H12 + 8O2-----> 5CO2 + 6H2O
Hence the answer above.
Which of the following is a possible compound formed from Ca2+ and NO3-1?
F Ca2NO3
G Ca(NO3)2
H Ca3NO2
J CaNO
Answer:
Ca(NO3)2
.................
Ca(NO3)2 is a possible compound formed from Ca²+ and NO3-¹.
Ions, which are charged atoms of elements come together to form ionic compounds. A positively charged ion called cation reacts with a negatively charged ion called anion to form a neutral ionic compound i.e. compound with a charge of 0. In this question, cation Ca²+ reacts with anion NO3-. The ionic compound formed must have a net charge of 0. This can only happen if 2 moles of NO3- and 1 mole of Ca²+ is present in the compound. The resulting ionic compound can be chemically represented as Ca(NO3)2. Therefore, Ca(NO3)2 is a possible compound formed from Ca²+ and NO3-¹.Learn more at: https://brainly.com/question/11148793?referrer=searchResults
Where do most earthquakes occur? Where do most volcanoes occur? Why do they occur here?
Answer:
The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. The majority of Earth's volcanoes and earthquakes take place along the Ring of Fire
Explanation:
Answer:
Most earthquakes occur along the edge of the oceanic and continental plates. The belt exists along boundaries of tectonic plates, where plates of mostly oceanic crust are sinking beneath another plate.
Most volcanoes are found along a belt, called the “Ring of Fire” that encircles the Pacific Ocean. As the plates move, they spread apart, collide, or slide past each other. Sixty percent of all active volcanoes occur at the boundaries between tectonic plates.

Determine the number of moles in a sample of calcium that contains 6.34 x 1022
atoms.
Answer:
0.105 molesExplanation:
To find the number of moles in a substance given it's number of entities we use the formula
[tex]n = \frac{N}{L} \\[/tex]
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
[tex]n = \frac{6.34 \times {10}^{22} }{6.02 \times {10}^{23} } \\ = 0.105315...[/tex]
We have the final answer as
0.105 molesHope this helps you

can multiple people use one brainly account at the same time on a computer??
Answer:
No
Explanation:
...............................
Multiple people cannot use one brainly account at the same time on a computer.
No, multiple people cannot use the same Brainly account at the same time on a computer. Brainly accounts are designed to be used by individual users and are intended for personal use. Each user should have their own separate account to access and interact with the Brainly platform. Sharing an account among multiple people simultaneously can lead to confusion, conflicts, and potential violations of the platform's terms of service. It is recommended that each person creates their own individual account on Brainly for a smooth and personalized experience.
Hence, multiple people can't access brainly at the same time.

Explanation:
Which has a higher frequency: microwaves or blue light? How do you know?
Answer:
Microwaves
Explanation:
Microwaves have more energy than blue light
Among microwaves or blue light, blue light has a higher frequency. This is because blue light belongs to the visible region has a short wavelength and produces a higher amount of energy.
What is the relationship between frequency and wavelength?The frequency of any wave is inversely related to the wavelength. This means that when the frequency of the wave increases, the wavelength decreases. While the relationship between frequency is directly related to the energy.
According to the context of this question, gamma rays have the highest frequency and shorter wavelength, while radiowaves have a shorter frequency and the highest wavelength.
Therefore, blue light has a higher frequency. This is because blue light belongs to the visible region has a short wavelength and produces a higher amount of energy.

Answer:
Mass = 234 g
Explanation:
Given data:
Mass of NaCl produced = ?
Moles of chlorine = 2.0 mol
Solution:
Chemical equation:
2Na + Cl₂ → 2NaCl
now we will compare the moles of NaCl with chlorine gas.
Cl₂ : NaCl
1 : 2
2.0 : 2/1×2.0 = 4.0 mol
Mass of NaCl;
Mass = number of moles × molar mass
Mass = 4.0 mol × 58.5 g/mol

What is Zeff of phosphorus
Answer:
Explanation:
Here is an illustration showing how to "calculate" +5 as the effective nuclear charge (Zeff) for phosphorus. We are not implying that the electrons are in orbits here, this is simply showing inner shell electrons that shield the outer valence electrons from the full nuclear charge.
We have that The effective nuclear charge Z_{eff} of 3p electron in phosphorus atom is discovered to be approximately 4.80
[tex]Z_{eff}=4.8[/tex]
It is important to note that the Z_{eff} of an element can be defined simply as the average positive charge felt by an shell electron in an atom from the various electrons around it
Hence
The effective nuclear charge Z_{eff} of 3p electron in phosphorus atom is discovered to be approximately 4.80
