emmasim [6.3K]3 years ago
3 0

The promise of jobs and prosperity, among other factors, pulls people to cities. Half of the global population already lives in cities, and by 2050 two-thirds of the world's people are expected to live in urban areas. But in cities two of the most pressing problems facing the world today also come together: poverty and environmental degradation.

_CO2 + _H20 -> _C6H1206+ __O2
iVinArrow [24]

Answer: 6CO2 + 6H2O -> C6H1206 + 6O2

Explanation: This is a balanced chemical equation for photosynthesis. In photosynthesis, six molecules of carbon dioxide react with six molecules of water in the presence of sunlight to form one molecule of glucose and six molecules of oxygen. Photosynthesis is a process by which green plants manufacture their own food using sunlight. Plants cells have an organelle known as chloroplast which contains chlorophyll a green pigment that traps energy from the sun. The energy trapped by the chlorophyll is used by plants in the presence of carbon dioxide and water to drive the synthesis of glucose with the release of oxygen as the by-products.

I) predict which of the liquids would cause the largest decrease in mass of potato stick
oksian1 [2.3K]

Answer:

1 mol per dm3 sodium chloride solution

Explanation:

The liquid that would cause the largest decrease in the mass of the potato stick would be the one with  <u>1 mole per dm3 sodium chloride solution.</u>

<em>The water potential of a solution depends on the molarity of the solution, the higher the molarity, the lower the water potential and vice versa. Hence, a solution with higher molarity has the tendency to osmotically draw more water from the potato stick than a solution with lower molarity.</em>

Therefore, the potato stick will have the largest decrease in mass in 1 mol per dm3 sodium chloride when compared to the 0.5 and 0.1 mole per dm3 solutions.
