Answer:

The correct answer would be D. sea levels would rise.

Increase in temperature (for example due to global warming) increases the rate of melting of polar ice.

Consequently, the sea levels of the polar ecosystem would increase.

In addition, the melting of the ice caps also increases the temperature of the water in the oceans. As a result, the water expands which also increases the sea levels.

Answer:

1) CO₂

2) 0.2551 g

Explanation:

The balanced reactions are:

CaCO₃ + 2HCl → CaCl₂ + H₂O + CO₂

MgCO₃ + 2HCl → MgCl₂ + H₂O + CO₂

1) The gas produced is CO₂.

2) Calculate mass of CaCO₃:

(0.5236 g) (0.4230) = 0.2215 g CaCO₃

Convert to moles:

(0.2215 g CaCO₃) (1 mol / 100.1 g) = 0.002213 mol CaCO₃

Find moles of CaCO₃:

(0.002213 mol CaCO₃) (1 mol CO₂ / mol CaCO₃) = 0.002213 mol CO₂

Convert to mass:

(0.002213 mol CO₂) (44.01 g / mol) = 0.09738 g CO₂

Calculate mass of MgCO₃:

(0.5236 g) (0.5770) = 0.3021 g MgCO₃

Convert to moles:

(0.3021 g MgCO₃) (1 mol / 84.31 g) = 0.003583 mol MgCO₃

Find moles of MgCO₃:

(0.003583 mol MgCO₃) (1 mol CO₂ / mol MgCO₃) = 0.003583 mol CO₂

Convert to mass:

(0.003583 mol CO₂) (44.01 g / mol) = 0.1577 g CO₂

Total mass of CO₂:

0.09738 g CO₂ + 0.1577 g CO₂ = 0.2551 g CO₂

andrey2020 [161]

Answer:

The cell membrane separates the external and internal environment of the cell. The cell membrane is composed of bilayer lipids, proteins and small amount of carbohydrates.

The lipid part is soluble in hydrophobic environment or with the hydrophobic part of other phospholipids because like molecules dissolve in like molecules. The hydrophobic part is non polar and hydrophilic parts is able to dissolve in polar area due to the interaction of same molecules with each other.
