What is the name given to an ion that has lost electrons? someone help me please D:
marin [14]

The name given to an ion that has lost electrons is cation. Details about cations can be found below.

<h3>What is a cation?</h3>

A cation is a positively charged ion i.e. the one that would be attracted to the cathode in an electrolytic procedure.

Generally, an ion is an electrically charged atom. An ion can either be positively charged or negatively charged. The latter is called an anion while the former is called a cation.

A cation is formed when an atom loses electrons to become positively charged while an anion is formed when an atom accepts electrons to become negatively charged.

Therefore, it can be said that the name given to an ion that has lost electrons is cation.

Write the expression for the equilibrium constant for this reaction. 2N205(g) &lt;==&gt; 4N02(g) + 02(g)
Elis [28]

Answer:

K = [NO₂]⁴[O₂] / [N₂O₅]²

Explanation:

Based on the chemical equilibrium reaction:

2 N₂O₅(g) ⇄ 4NO₂(g) + O₂(g)

The equilibrium reaction is obtained as the ratio between the multiplication of the concentrations of the reactants over the products powered to its reaction coefficient. That is:

<h3>K = [NO₂]⁴[O₂] / [N₂O₅]²</h3>

Identify the balanced chemical equation that represents a combustion reaction. 2C 4H 10 + 13O 2 ⟶ 10H 2O + 8CO 2 C 4H 10 + 5O 2
kati45 [8]

Answer:

  2C₄H₁₀ + 13O₂ ⟶ 10H₂O + 8CO₂

Explanation:

  2C₄H₁₀ + 13O₂ ⟶ 10H₂O + 8CO₂  . . . . .  balanced combustion reaction

  C₄H₁₀ + 5O₂ ⟶ 5H₂O + 4CO₂  . . . . not balanced

The two reactions involving Ca are not combustion reactions.

For the reaction 5 o2(g) + 4 nh3(g)  4 no(g) + 6 h2o(g) if nh3 is being consumed at a rate of 0.50 m•s –1 , at what rate is h2o
Anika [276]
<span>In the given chemical equation, 4 moles of nh3 gas react with 5 moles of oxygen to form 6moles of water vapours (h2o). Hence each mole of nh3 contributes to production of 1.5 moles of water vapours. therefore, the rate of formation of h2o is 1.5*0.5 ms-1, i.e 0.75 moles/sec</span>
