According to the given reaction, 2 moles of As react with 6 moles of NaOH. Use this ratio to find how many moles of NaOH react with 492 moles of As.

It means that you need 1476 moles of NaOH to use 492 moles of As all up.
Density = mass/volume
So..
D = 10.74/5
D = 2.148 g/mL ^3
The flask would break, the flare would drop and the ether would light on fire.
Critical thinking involves questioning and evaluating information. Critical and creative thinking both contribute to our ability to solve problems in a variety of contexts. Evaluating information is a complex, but essential, process. You can use the CRAAP test to help determine if sources and information are reliable.
The key critical thinking skills are: analysis, interpretation, inference, explanation, self-regulation, open-mindedness, and problem-solving.
Critical thinking skills are important because they enable students “to deal effectively with social, scientific, and practical problems” (Shakirova, 2007, p. 42). Simply put, students who are able to think critically are able to solve problems effectively. Merely having knowledge or information is not enough.
Hope it helps
1. The answer is; buried deep within
The deeper you go into the earth’s crust, the higher the pressure. This is due to the weight of the overlying layers of rock. Due to this pressure, there is also great heat. This heat and pressure cause the molecules of the rocks to realign themselves and the crystals of the room change causing the rock to metamorphose into a different rock.
2. The answer is; magma
Apart from the heat that is associated with the enormous pressure in the great depths of the earth crust due to the weight of overlying rock layers, magma in magma chambers in the crust also part of the intense heat in these regions. This heat changes rocks into metamorphic rocks.
3. The answer is; foliated
The pressure and temperatures in the earth's crust are not uniform. A part of rock may be subjected to a slightly higher temperature and pressure compared to another region of the rocks. This unevenness causes different crystal structures and orientations at different points in the rocks making the rock appear layered or banded.
