Acetylene C2H2 gas is often used in welding torches because of the very high heat produced when it reacts with oxygen O2 gas, pr

yawa3891 [41]

Answer:

The correct answer is 0.11 mol O₂

Explanation:

The chemical equation for the reaction of acetylene (C₂H₂) with O₂ to produce carbon dioxide (CO₂) and water (H₂O) is the following:

2 C₂H₂(g) + 5 O₂(g) → 4 CO₂(g) + 2 H₂O(g)

The chemical equation is balanced : with the proper estequiometrical coefficients. According to this, 2 moles of C₂H₂ reacts with 5 moles of O₂ to give 4 moles of CO₂ and 2 moles of H₂O.

In order to calculate how many moles of O₂ are needed to produce 0.085 moles of CO₂, we multiply the 0.085 moles of CO₂ by the factor 5 moles O₂/4 moles CO₂ (because 4 moles of CO₂ are produced by 5 moles of O₂ according to the chemical equation):

0.085 moles CO₂ x (5 moles O₂/4 moles CO₂) = 0.10625 moles O₂ = 0.11 moles O₂

Rank the ions in each set in order of increasing size, and explain your ranking:

Paha777 [63]

Explanation:

Lithium, sodium and potassium are all group 1A elements and when we move down a group then there occurs an increase in atomic size of the elements. As lithium is the smallest and potassium being the largest so, when each of them will lose an electron and obtain a positive charge then size of lithium will further decrease.

Therefore, ions are ranked according to their increase in size as follows.

$Li^{+} < Na^{+} < K^{+}$

When an atom tends to gain electrons then it acquires a negative charge. This means that size of the atom increases.

So, more is the negative charge present on an atom more will be its atomic size. Therefore, correct order of increasing size for $Se^{2-}, Rb^{+}, Br$ is as follows.

$Br < Rb^{+} < Se^{2-}$

Similarly, order of increasing size of $O^{2-}, F^{-}, N^{3-}$ is as follows.

$F^{-} < O^{2-} < N^{3-}$
