If 15.0 grams of AlBr3 are produced, how many grams of aluminum are needed?

Round your answer to two decimals.
Please i need this asap

Answers

Since AlBr3 is the sole product, we can use its coefficient to determine its molar ratio with Al. Conveniently, that ratio is 2:2 or, simplified, 1:1, which means that the number of moles of AlBr3 produced is equivalent to the number of moles of aluminum consumed in the reaction.

We must determine the number of moles of AlBr3 produced; we are given the mass of AlBr3 produced, so we divide the mass by the molar mass of AlBr3:

(15.0 g)/(266.694 g/mol) = 0.05624 mol AlBr3

Since the molar ratio of AlBr3:Al is 1:1, that means 0.05624 moles of Al were reacted. Now, all that is left is to convert the number of moles of Al to grams. We multiply the number of moles by the molar mass of Al:

(0.05624 mol)(26.982 g/mol) = 1.52 grams Al.

So, if 15.0 grams of AlBr3 are produced in this reaction, 1.52 grams of Al are needed.

Which statement is true about the ionic size of the elements in a group as one moves from bottom to top in that group?


Ionic size decreases from bottom to top within the group.


Ionic size increases from bottom to top within the group.


Ionic size does not vary in any predictable way within the group.


Ionic size stays the same within the group.

Answers

Answer:

helium

Explanation:

The first ionization energy varies in a predictable way across the periodic table. The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Thus, helium has the largest first ionization energy, while francium has one of the lowest.

Answer: 2nd answer " C "

Explanation:

First ionization energy is a periodic trend that increases up and to the right on the periodic table. After looking at the position of these elements on the periodic table, carbon is clearly the best answer-choice (B) aka " C "

Coniferous forests grow in a wide range of climates, from the coldest polar regions to the warmest tropical regions and everything in between. This statement is true.

What are conifers ?

Conifers are  a type of gymnosperm plants bearing cone like structures in which the seeds are located. Don't be fooled by the fact that coniferous woods are widespread around the world. Some of the wildest trees in the world can be found there.

Hyperion, a coastal redwood tree, is the tallest tree in the world, reaching a height of 379 feet, equivalent to a 35-story structure. From Siberia to Canada, coniferous rainforest biomes can be found. They have cold winters and warm to hot summers.

Temperatures in coniferous forests are quite low all year long. Summertime temperatures range from -7°C to 21°C, while the average wintertime temperature ranges from -54°C to -1°C. Hence, the statement is true.

1. When aqueous solutions of lead(II) nitrate (Pb(NO3)2) and sulfuric acid
(H2SO4) react, lead(II) sulfate forms as a precipitate. Identify the spectator
ions and write a balanced net ionic equation for this reaction.

The ions Pb2+ and SO42- combine to form the precipitate.

Which two ions are spectator ions?

The net ionic reaction is Pb2+ + SO42...

Answers

The spectator ions would be the ions that don't comprise the precipitate in this reaction. You have four ionic species here: Pb²⁺, NO₃⁻, H⁺, and SO₄²⁻. Since Pb²⁺ and SO₄²⁻ combine, as you are told, to form the precipitate, that leaves H⁺ and NO₃⁻ (or, in normal text, H+ and NO3-) to be the spectator ions.

Edit: NO3- might be interpreted ambiguously since it's not immediately clear that the NO3 is a polyatomic ion with a -1 charge and not an NO compound with a 3- charge, so it should be written as [NO3]- or (NO3)-.

The net ionic reaction shows the reaction without the spectator ions. In this case, that would be: Pb²⁺(aq) + SO₄²⁻(aq) → PbSO₄(s).

What happens when a particle and its antiparticle collide? (2 points)
O They combine nuclei
O They break into quarks
They are converted to energy
O They become antimatter

Answers

I believe they are converted to energy

When a particle and its antiparticle collide they are converted to energy.

What is collide?

A colloid would be a mixture in which a component made up of insoluble particles that are scattered at a microscopic scale is suspended within another component.

What is energy?

In order to accomplish work and to produce heat as well as light, energy must be supplied to a body or even to a physical system. Energy would be the quantitative attribute that does this. Energy would be transformed in form but cannot be created and destroyed, according to the rule of conservation of energy.

Annihilation occurs when a particle collides including its anti-particle. The particle and its antiparticle's whole mass are transformed back into energy to produce two gamma-ray photons. You won't find antiparticles in everyday stuff since they typically barely last for a tiny amount of time until annihilation takes place.

Therefore, the correct answer will be option (c).

What is the molarity of 930 mL of LiCl solution that contains 139.9 g of LiCI?
A. 3.5 mol/L
B. 150 mol/L
C. 3.3 mol/L
D. 3.5 x 10-3 mol/L

Answers

Answer:  A) 3.5 mol/L

Explanation:

To determine the molarity, we have to find the number of moles in the volume given, and then extrapolate to find the number of moles that would be in 1 L.

Determine the moles in the given volume

moles of LiCl = mass ÷ molar mass

                       = 139.9 g ÷ 42.39 g/mol

                       = 3.30 mol

Find the moles in 1 L

    Since 930 mL of LiCl    =   3.30 mol

    then 1000 mL of LiCl    =   (3.30 mol × 1000 mL/L) ÷ 930 mL

                                           =  3.55 mol/L

what is the maximum wavelength of photon that will eject a ground state electron from a hydrogen atom?

Answers

Answer:

9.13 x 10^-8 m

Explanation:

The maximum wavelength of photon that will eject a ground state electron from a hydrogen atom is 9.18 * 10^-8.

What is wavelength?

Wavelength is defined as the distance between identical points in the adjacent cycle of a waveform signal propagated in space or along the wires.

Wavelength is calculated as wave speed and frequency.

Wavelength = speed/frequency

SI unit of wavelength is meter.

A ground state atom is an atom in which total energy of the electron can not be lowered by transferring one or more electrons to different orbitals.

Thus, the maximum wavelength of photon that will eject a ground state electron from a hydrogen atom is 9.18 * 10^-8.
