For the love of god answer these questions for it’s urgent.
1. some igneous rock forms from magma that cools slowly within earth’s crust. briefly describe the most likely crystallization and texture of the rock.
2. other igneous rock forms from lava that cools quickly on earth’s surface. classify the rock as either intrusive or extrusive, and identify another word used to describe this type of rock.
3. you are studying a sample of igneous rock. the rock formed on the surface of earth. it’s made mostly of light-colored minerals. the sample has just a few specks of dark-colored minerals. classify the rock by type and composition.
4. you are studying a sample of igneous rock. the rock formed within earth’s crust. the sample contains a very high concentration of dark-colored, high-density minerals. classify the rock by type and composition.
5. a scientist shows you a sample of rock called gabbro. the scientist explains that gabbro is an intrusive mafic igneous rock. explain what this means.

The p sub shell can hold up to 8 electrons in an atom. true or false?

Both josef loschmidt and amedeo avogadro contributed to our understanding of basic molecular numbers, sizes, and reaction ratios. neither scientist discovered “avogadro’s number” in the form we use it today (6.02 x 10 23). still, there’s a controversy over the name. research the contributions from these two scientists and read about how avogadro’s number got its name. briefly state what you think this number should be called, providing key details of each scientist’s contributions to this concept and a solid rationale for your case in naming the number.

Straightforward questions answered in the powerpoint slidesreaction: heating the starting materials under refluxwhat does it mean to heat under reflux? why do we choose water as the reflux solvent? what are boiling chips used for? why do we put a condenser on top of the reaction? why do we add heat and let the reaction stir for 30 minutes? why do we add sulfuric acid to the reaction after it cools as opposed to when it’s still hot? separation: filtration of precipitatewhy don’t we do an aqueous and organic extraction in the separatory funnel? why do you rinse the salicylic acid on the filter with ice cold water? purification: recrystallization of salicylic acid (no hot filtration needed)what is the difference in the amount of room temperature water vs. boiling water needed to dissolve the salicylic acid (assume a 1.2 gram yield of salicylic acid)? remember, in the lab if you need x ml of boiling water to dissolve a solid, then you should add a little more (definitely no more than 1.5 times the theoretical amount) to ensure it doesn’t recrystallize prematurely.analysis: melting point of salicylic acidwhat can you conclude if the melting point of the salicylic acid you just synthesized is 152-155oc and the 1: 1 mix of your product and “synthetic” salicylic acid is 151-154oc?
