Condesation is: water that collects as droplets on a cold surface when humid air is in contact with it.
An example would be: having a cold soda on a hot day, the can "sweats." Water molecules in the air as a vapor hit the colder surface of the can and turn into liquid water.
Answer:
1. Light-dependent stage
2. Light-independent stage or Calvin cycle
Explanation:
Photosynthesis is the process by which plants and other autotrophic organisms synthesize their food (glucose) in the presence of sunlight as energy source. However, this photosynthetic process, which is a metabolic reaction occurs in two stages namely; Light-dependent stage and Light-independent stage.
- The light dependent stage occurs in the thylakoid membrane of the chloroplast. It involves the synthesis of NADPH and ATP needed for the light independent stage of photosynthesis.
- The light independent stage also known as Calvin cycle occurs in the stroma of the chloroplast. This is the stage where glucose is synthesized using inorganic source of carbon (CO2).
Yes. That is a mixture. You are allowed to remove the sugar because there is sugar molecules in the water.
Answer:
14. (C) -3; 16. B. 0, 3
Explanation:
14. Ionic charge
X: ns²np³.
The element is three electrons short of having a complete octet.
It is likely to react chemically to add those three electrons and form an X³⁻ ion.
16. Orbitals in subshells
The n = 1 shell contains no p orbitals. All the other shells contain three p orbitals.
The n = 1 shell contains only one s orbital. Every higher shell contains a p subshell, and each p subshell contains three p orbitals.
The correct answer is A. molecular formula = 2 x empirical formula
The given compound C2H10N2 is the molecular formula because the ratios of the elements are not reduced into lowest terms (empirical formula). To get the empirical formula, the ratios must be reduced to the smallest possible integral ratio which gives CH5N. As a result, the ratio between both formulas is 2.
