Calculate ΔH for the reaction: C(graphite) + 2H 2(g) + 1/2 O 2(g) => CH 3OH(l) Using the following information: C(graphite) +

Alika [10]

Answer:

$\Delta H$ for the given reaction is -238.7 kJ

Explanation:

The given reaction can be written as summation of three elementary steps such as:

$C(graphite)+O_{2}(g)\rightarrow CO_{2}(g)$ $\Delta H_{1}= -393.5 kJ$

$2H_{2}(g)+O_{2}(g)\rightarrow 2H_{2}O(l)$ $\Delta H_{2}= (2\times -285.8)kJ$

$CO_{2}(g)+2H_{2}O(l)\rightarrow CH_{3}OH(l)+\frac{3}{2}O_{2}(g)$ $\Delta H_{3}= 726.4 kJ$

---------------------------------------------------------------------------------------------------

$C(graphite)+2H_{2}(g)+\frac{1}{2}O_{2}(g)\rightarrow CH_{3}OH(l)$

$\Delta H=\Delta H_{1}+\Delta H_{2}+\Delta H_{3}=-238.7 kJ$

How do scientists classify intrusive igneous features? according to shape, texture, and their distance from the nearest volcanic

Nataliya [291]

according to shape, size, and their relationship to surrounding layers of rock

Explanation:

Scientists classify intrusive features according to their shape, size and relationship to surrounding layers of rocks.

Intrusive igneous features are the sills, di/kes, batholith, laccoiith, lopolith e.t.c

When magma cools and solidifies within the earth crust, they form intrusive igneous rocks.
Intrusive igneous rocks differs from one another in their shape, size and relationship to surrounding rocks.
For example, batholith is a large intrusive body that extends for several kilometers in the earth surface.
Sills and di/kes are smaller bodies. Sills forms parallel to orientation of rocks in an area. Di/kes are known to cut across the orientation.
