Which element is the excess reagent when 3.00 moles of Mg is ignited in 2.20 moles of pure oxygen
Artyom0805 [142]

Answer:

Oxygen is in excess.

Explanation:

The coefficients of the balanced equation create a mole ratio that shows the ratio of how many reactants are used up and products are created.  

The mole ratio of Mg to O2 in this equation is 2:1, which means that for every two moles of Mg used, there will be 1 mole of O2 used.

If we have 3.00 moles of Mg, we will only need 1.5 moles of oxygen to completely burn the Mg. Therefore, when all 3.00 moles of Mg are used, there will still be some of the 2.20 moles of oxygen remaining.

What is the role of gluons?
igor_vitrenko [27]

The role of the gluons is to bind together the quarks that make up protons and neutrons. That is option D.

<h3>What are gluons?</h3>

Gluons are those particles found within an atom that are responsible for binding protons and neutrons together inside the nucleus of an atom.

The gluons are capable of binding the protons and neutrons together by holding together the quarks that makes up protons and neutrons.

These gluons are known to carry a color-anticolor charge which makes up the 9 types of gluons which include:

  • red anti-red,

  • red anti-blue,

  • red anti-green,

  • blue anti-red,

  • blue anti-blue,

  • blue anti-green,

  • green anti-red,

  • green anti-blue, and

  • green anti-green.

An atom is the smallest indivisible part of an element that can take part in a chemical reaction.

The proton is the positive particle of an atom which is found within the nucleus.

The neutron is the particle that is found in the nucleus of an atom which doesn't have any charge.
