Answer:

Explanation:

Volcanic eruptions spew large amounts of dust particles from their surroundings into the atmosphere. Accompanying eruptions are also materials like volcanic ash and gases. These gases contribute immensely to the reserve of greenhouse gases in the atmosphere.

Gases in volcanoes are responsible to a large extent for their explosivity when an eruption occurs. The more the gases, the more explosive a volcano can be. These gases are rich in carbon dioxide, methane, etc. A vast number of them are greenhouse gases.

Dust particles also accompany an eruption. These dust can be suspended for an extended period in the atmosphere by the wind.

the best choice is the letter D. Volcanic eruptions add green house gases and fine dust particles to the atmosphere.

Answer:

8.912x10^-18

Explanation:

-dn/dt = pANa/2piMRT

100 g = initial copper

Number of moles = 100/63.546

= 1.5736

Mass of copper left = 100-10.0168

= 89.9832

Moles = 89.9832/63.546

= 1.4160

dn = 1.4160-1.5736

= -0.1576

dt = 2 hrs

A = 3.23mm² = 3.23x10^-6

M = 63.546

T = 0.0821

T = 1508k

Na = 6.023x10²³

When we insert all these into the formula above

We get

P = 8.912x10^-18atm

Saturated aqueous sodium chloride(d=1.2g/mL) is added to the following mixtures in order to dry the organic layer. Which layer i

natali 33 [55]

(a) at the bottom - high density organic compound dissolved in methylene chloride

(b) at the bottom - saturated aqueous sodium chloride

Explanation:

Sodium chloride is dissolved in water while the organic compounds are dissolved in methylene chloride. After mixing the two solutions two layers will form because water (polar molecule) will not mix with the methylene chloride (nonpolar molecule).

The layer with higher density will be at the bottom.

(a) saturated aqueous sodium chloride (d = 1.2 g/mL) - upper layer

high density organic compound dissolved in methylene chloride (d = 1.4 g/mL) - bottom layer

(b) saturated aqueous sodium chloride (d = 1.2 g/mL) - bottom layer

low density organic compound dissolved in methylene chloride (d = 1.1 g/mL) - upper layer
