Answer:

A. Four C–H single bonds and two O=O double bonds.

Explanation:

  • The chemical reaction proceeds with breaking bonds in the reacting molecules and forming new bonds in the products.
  • In this reaction four single bonds are broken in CH₄ and two double bonds O=O are broken in two molecules of O₂.
  • Also, two double bonds C=O are formed in CO₂ molecules and 4 single bonds O–H are formed in 2 molecules of H₂O <em>(each molecule contain 2 new bonds)</em>.
  • <em>So, A is the right answer.</em>

The methane molecule undergoes oxidation and the carbon is oxidized to carbon dioxide and hydrogen to water.

In this reaction there is cleavage of four C-H bonds and two O=O bonds

there will be formation of two C=O bonds and four O-H bonds.

Overall due to more bond cleavage energy there will be evolution of energy. thus combustion is an exothermic reaction.

An intravenous infusion is to contain 15 mEq of potassium ion and 20 mEq of sodium ion in 500 mL of 5% dextrose injection. Using
Studentka2010 [4]

Answer:

To supply the required ions it is necessary to inject 5,6mL of 6g/30mL solution and 131,1 mL of 0,9% solution.

Explanation:

1mEq of sodium are 59mg of NaCl and 1mEq of potassium are 75mg KCl

in intravenous infusion 15 mEq of K are:

15x75mg KCl = 1,125g of KCl

And 20 mEq of Na are:

20x59mg NaCl = 1,18g of NaCl

To supply the potassium ion it is necessary to inject:

1,125g of KCl×\frac{30mL}{6g} =<em> 5,6mL  of 6g/30mL solution</em>

And, to supply the sodium ion it is necessary to inject:

1,18g of NaCl×\frac{100mL}{0,9g} = <em>131,1 mL of 0,9% solution</em>

I hope it helps!
