Consider the reaction ch4 + 2 o2 → co2 + 2 h2o exactly 14.5 moles of co2 are produced upon reaction of 34.6 moles of o2 and how many moles of ch4?

14.5 moles of methane had produced 14.5 moles of carbon dioxide.

Explanation:

Moles of oxygen gas = 34.6 moles

According to reaction 1 mole of methane reacts with 2 moles of oxygen.

The 34.6 moles of oxygen gas will react with :

of methane

According to reaction 1 mole of methane gives 1 moles of carbon dioxide .

The 14.5 moles of carbon dioxide gas will be obtained from:

of methane

As we can see that oxygen is present in an excess , which means that formation of carbon dioxide would have depend upon moles of methane.

So, the moles of methane used to form 14.5 moles of carbon dioxide will be:

of methane

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.

the answer is 75.0%.
