Answer: Chloroplast- A) An organelle that contains chlorophyll and in which photosynthesis takes place.

Chlorophyll- C) A green pigment present in all plants that absorbs light to provide energy for photosynthesis

Energy- B) A capacity to do work that can produce physical changes within living and nonliving systems.

Glucose- D) A type of sugar that is produced during photosynthesis to store chemical energy

Explanation:

Chloroplast- A) An organelle that contains chlorophyll and in which photosynthesis takes place:  In plants, chloroplasts is a organelle found in the leaves or green cells in which the process of photosynthesis takes place.

Chlorophyll- C) A green pigment present in all plants that absorbs light to provide energy for photosynthesis: Chlorophyll is a green pigment, found in the chloroplast organelle of plant cells. These pigments captures energy from sunlight. The light energy is used to produce food in the form of carbohydrates.

Energy- B) A capacity to do work that can produce physical changes within living and nonliving systems: Energy in the form of light, heat and chemical brings physical changes in the form, structure and function of living and non-living systems.

Glucose- D) A type of sugar that is produced during photosynthesis to store chemical energy: Photosynthesis is a biochemical pathway, in which energy from sun is converted into food in the form of glucose. The food energy is used to prepare chemical energy required for various metabolic activities in plants such as respiration. The chemical energy is produced in the form of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate).

How many molecules (not moles of nh3 are produced from 5.01×10?4 g of h2?
Irina-Kira [14]
2,02g     -------    6,02×10²³
5,01×10⁴g  ---    x

x=\frac{5,01*10^{4}g*6,02*10^{23}}{2,02g}=14,93*10^{27}

N₂         +        3H₂       ⇒           2NH₃
1mol      :        3mol        :           2mol
                       18,06×10²³  :       12,04×10²³
                       14,93×10²⁷  :        y

y=\frac{14,93*10^{27}*12,04*10^{23}}{18,06*10^{23}}\approx9,95*10^{27}

How many hydrogen atoms are in 5.20 mol of ammonium sulfide?
Fofino [41]
1) Molecular formula of ammonium sulfide

(NH4)2 S

2) That means that there are 2*4 = 8 atoms of hydrogen in each molecule of ammoium sulfide, so in 5.20 mol of molecules will be 8 * 5.20 mol = 41.6 moles of atoms of hydrogen

3) To pass to number of atoms multiply by Avogadro's number: 6.022 * 10^23

41.6 moles * 6.022 * 10^23 atoms / mol = 250.5 * 10^23 = 2.50 * 10^25 atoms

Answer: 2.50 * 10^25

What is the value of the activation energy of the uncatalyzed reaction?
Lubov Fominskaja [6]
The value of the activation energy of an uncatalyzed reaction is greater than that of a catalyzed reaction. As we know, a catalyst provides an alternative path for the reaction to happen at a faster rate. So, for a catalyzed reactio, activation energy is lesser than the original path.
