What's the deffinition of igneous rock
Aliun [14]
<span>Igneous rocks are those rocks that were formed through cooling and solidifying the molten materials. The best example for igneous rock is solid volcanic java. Lava are liquid that comes from a volcano, but once it is dried and solidify, it becomes a rock and called igneous rock.
Another example is the granite and basalt. And according to research igneous rock comes from the latin word ignis which means fire. Thus this says it all. From a liquid becomes a rock.

Caffeine, a stimulant found in coffee and soda, has the following elemental composition: 49.48% carbon, 5.19% hydrogen, 16.48% o
prisoha [69]

Answer:

Explanation:

C = 49.48

H = 5.19

O = 16.48

N = 28.85

ratio of moles

= 49.48 / 12 : 5.19 / 1 : 16.48 / 16 : 28.85 / 14

= 4.123 : 5.19 : 1.03 : 2.06

= 4 : 5 : 1 : 2

so the empirical formula = C₄ H₅O N₂

Let molecular formula = (  C₄ H₅ON₂ )ₙ ,

n ( 48 + 5 + 16 + 28 ) = 119.19

97 n = 194.19

n = 2 ( approx )

molecular formula = C₈ H₁₀O₂ N₄

WARRIOR [948]
The semi will have the hardest time changing direction because of its mass. The more mass there is, the more effort it takes to accelerate and decelerate as well as change direction.

Imagine that you're doing an experiment that requires you to smell the odor of a chemical solution in a beaker. Which procedure
mixas84 [53]

The correct answer really is B.

If you are directed to break that rule then you better be in a high level chemistry class. When I taught things like that I insisted that students just wait until the chemical permeated the fume cabinet and even then I was always very nervous.

Sometimes you have to know when to ignore a bad direction. If you are working with chlorine, for example, you should be especially careful. That stuff was used in WWI as part of a chemical warfare technique. Many men suffered grotesque deaths by breathing it in, particularly if they were in trenches. Chlorine is heavier than air. It sinks to the lowest level.
