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

your answer is c) plasma

weight of any object is given by

w = m*g

where m is mass of the object and g is the acceleration due to gravity.

for earth the value of g is 9.8 m/s^2 so

w=117.6 n m=12 g=?

117.6=12g => g=9.8 m/s^2

which is the force of gravity on earth.
