Answer:
The answer to your question is: SiCl₄
Explanation:
Data
amount of Si 1.71 g
amount of Cl 8.63 g
MW Si = 28 g
MW Cl = 35.5
Process (rule of three)
For Si For Cl
28 g of Si ------------------ 1 mol 35.5 g of Cl --------------- 1 mol
1.71g of Si --------------- x 8.63 g of Cl -------------- x
x = 1.71 x 1 / 28 = 0.06 mol x = 8.63 x 1 / 35.5 = 0.24 mol
Now, divide both results by the lowest of them.
Si = 0.06 mol / 0.06 = 1 molecule of Si Cl = 0.24 / 0.06 = 4 molecules of Cl
Finally
Si₁ Cl₄ or SiCl₄
Temperature is related to the kinetic energy the atoms within any given
substance. Within a solid, we can therefore assume that the density will
increase as the solid is cooled to a low temperature, as this will
cause a loss in kinetic energy and the atoms won't be able to move as
freely.
It’s A because those chemicals combines make 5.6 grams if you measure it.
Answer:
A. sulfur dioxide
Explanation:
The volcanoes are able to influence the global climate both on the short term and on the long term. The end result can be either cooling off of the climate, or warming up of it, depending on what type of gasses are the volcanoes going to release in the atmosphere, as well as how much of them. The sulfur dioxide is a gas that is released by the volcanoes that causes cooling off of the climate. This gas is going through conversion and becomes sulfuric acid, and it is able to restrict the amount of sunlight reaching the surface of the Earth, as well as increasing the reflective properties of the atmosphere, resulting in a few years of significant cooling of the climate.
