In the following equation, which element has been oxidized?

Chemistry
1 answer:
Bumek [7]4 years ago
6 0

The  element  that has  been  oxidized   is Al  (  Answer  A)


Explanation

 if  the oxidation number of an element is greater in the product side than the reactant  side  then the element   has lost  the electrons . This mean  that  the element  has been oxidized.

Al  is  oxidized  because  it move  from  oxidation  state  Zero(0)  in reactant side  to  oxidation state 3⁺  in product  side.

This  implies  that  Al  loses  3  electrons.

An isotope with the combination of subatomic particles (69n,50p+,50e-) is?
faust18 [17]

Answer:

A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below). Other particles exist as well, such as alpha and beta particles (which are discussed below). The Bohr model shows the three basic subatomic particles in a simple manner. Most of an atom's mass is in the nucleus—a small, dense area at the center of every atom, composed of nucleons. Nucleons include protons and neutrons. All the positive charge of an atom is contained in the nucleus, and originates from the protons. Neutrons are neutrally-charged. Electrons, which are negatively-charged, are located outside of the nucleus.

Which best explains how heat plays a role in the movement of materials within Earth's interior?
vfiekz [6]

Answer:

Hot material near the core is less dense and rises, when it cools, it becomes more dense and sinks.

Explanation:

This best explains how heat plays a role in the movement of materials within Earth's interior because it's how convection works. Convection is the circular motion that happens when warmer air or liquid which has faster moving molecules, making it less dense rises, while the cooler air or liquid drops down. Convection currents within the earth move layers of magma, and convection in the ocean creates currents.

Determine the limiting reactant in each of the following reactions:
wolverine [178]

The reactant in a chemical process known as the limiting reactant controls how much product can be produced. When the limiting reactant is completely used up, the reaction will come to an end.

<h3>Find the limiting reactant ?</h3>
  • As a result of 1 mol Sb4O6 reacting with 6 mol H2SO4, only 0.1 mol Sb4O6 reacts with 0.6 mol H2SO4, leaving only 0.5 mol H2SO4. This indicates that H2SO4 is the limiting reactant and Sb4O6 is present in excess.
  • According to your equation, which is balanced, 0.1 mol Sb4O6 should react with 0.6 mol H2SO4, yet there is only 0.5 mol H2SO4 on hand.
  • Therefore, only.083 mol of Sb4O6 are reacted.
  • The reactant that is present in the limiting amount—the limiting reactant—determines the extent to which a chemical reaction occurs.
  • The trick is really quite easy! We employ an augmented matrix to hold the data derived from the balancing equation Sb4O6 + 6H2SO4 --> 2Sb2(SO4)3 + 6H2O.
  • Although you are provided 0.5 mol of H2SO4, the reaction requires 0.6 mol. Therefore, the limiting reactant is H2SO4.
  • Only 0.0833 mol of Sb4O6 is required, but you have 0.1 mol. Sb4O6 is therefore the extra reactant.
