Explain why the viscosity of the lava causes 2 types of erruptions

UkoKoshka [18]

Answer: The two main factors that affect how viscous lava is are the mineral content of the lava and its temperature. Lava that contains more iron and magnesium, classifying it as basaltic or mafic, has a lower viscosity than lava that has more silicates and calcium, classifying that as rhyolitic or felsic. Additionally, lava at higher temperatures flows with less viscosity than lava at lower temperatures, especially when the temperature allows some of the minerals in the lava to crystallize.

A 1.638 Gram pure sample of a compound containing only carbon hydrogen and oxygen was burned in excess oxygen gas 3.117 g of car

andrew11 [14]

Answer:

C2H6O

Explanation:

First, find the masses of C, H, and O. I used ratios.

3.117g CO2 x 1 mol CO2/44.01g CO2 x 1 mol C/1 mol CO2 x 12.01g C/1 mol C = 0.850606 g C

1.911g H2O x 1 mol H2O/18.016g H2O x 2 mol H2O/1 mol H2O x 1.008g H/1 mol H = 0.213842 g H

To find the mass of oxygen, just add the masses of C and H together and subtract that from the total mass of the sample.

1.638 - (0.850606 + 0.213842) = 0.57355 g O

Second, find the moles of C, H, and O.

0.850606g C x 1 mol C/12.01g C = 0.070825 mol C

0.213842g H x 1 mol H/1.008g H = 0.212145 mol H

0.57355 g O x 1 mol O/16g O = 0.035847 mol O

Finally, divide the number of moles of each element by the smallest value of moles calculated. In this case, the smallest value is 0.035847.

0.070825/0.035847 = 2

0.212145/0.035847 = 6

0.035847/0.035847 = 1

Avogadro’s law states that the volume (V) and number of moles (n) are directly proportional if the pressure and temperature both

natima [27]

Answer: $\frac{V_1}{V_2}=\frac{n_1}{n_2}$

Explanation:

According to the Avogadro's law, the volume of gas is directly proportional to the number of moles of gas at same pressure and temperature. That means,

$V\propto n$

or,

$\frac{V_1}{V_2}=\frac{n_1}{n_2}$

where,

$V_1$ = initial volume of gas

$V_2$ = final volume of gas

$n_1$ = initial moles of gas

$n_2$ = final moles of gas
