Ch4 + 2o2 → co2 + 2h2o, δh = -890 kj/mol how much energy is released when 59.7 grams of methane (ch4) reacts with oxygen?

- 3321 kJ of heat is released.

Solution:- The given balanced equation is:

From this balanced combustion equation, 890 kJ of heat is released by the combustion of 1 mol of methane.

We could convert given grams of methane to moles and multiply by the delta H value of the reaction to get the total heat released by the combustion of 59.7 grams of methane as:

= -3321 kJ

The negative sign indicates the heat is released. So, 3321 kJ of heat is released by the combustion of 59.7 grams of methane.

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.
