Chemistry
1 answer:
GrogVix [38]3 years ago
8 0
Answer:

5

Explanation:

In order to be able to say how many sig figs are used for the measurement 811.40 g, you need to know that

<span><span>non-zero digits are always significant</span><span>a trailing zero that follows a decimal point and a non-zero digit is always significant</span></span>

In your case, the measurement

<span>811.40</span>

has four non-zero digits and one significant trailing zero.

<span><span><span>8,1,1,4</span>→</span> non-zero digits<span><span>8,1,1,</span>0→</span> significant trailing zero</span>

Therefore, you can say that this measurement has <span>five significant figures</span>

<span>811.40→</span> <span>five significant figures</span>

What begins to happen to radioactive uranium as soon as a mineral containing it crystallizes from magma?
Aleonysh [2.5K]
<span>The radioactive uranium decays into its daughter product, lead. It would do this in magma as well, as nuclear decay depends on forces within the atom, not on the phase of the material in which the atom is a part.</span>

Calculate ΔH for the reaction: C(graphite) + 2H 2(g) + 1/2 O 2(g) =&gt; 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
