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).

The ph of 0.015 m hno2 (nitrous acid) aqueous solution was measured to be 2.63. what is the value of pka of nitrous acid?
Licemer1 [7]
Nitrous acid<span> dissociates as follows:
</span>
HNO₂(s) ⇄ H⁺(aq) + NO₂⁻(aq) 
           
According to the equation, an acid constant has the following form:

Ka = [H⁺] × [NO₂⁻ ] / [HNO₂] 

From pH, we can calculate the concentration of H⁺ and NO₂⁻:

[H⁺] = 10^-pH = 10^-2.63 = 0.00234 M = [NO₂⁻]

Now, the acid constant can be calculated:

Ka = 0.00234 x 0.00234 / 0.015  = 3.66 x 10⁻⁴

And finally,

pKa = -log Ka = 3.44

If you had an object with a mass of 76g and a volume of 22 ml, what is its density? If you cut this object in half, what would b
V125BC [204]
D = M/V = 76g / 22ml = 3.4g/ml

Half ~ D = 38g / 11ml = 3.4g/ml

Even if the object you had was cut in half, it’s density would remain the same.

Vesnalui [34]

Answer:

0.01917 m^3/kg.

Explanation:

Given:

P = 15 MPa

= 1.5 × 10^4 kPa

T = 350 °C

= 350 + 273

= 623 K

Molar mass of water, m = (2 × 1) + 16

= 18 g/mol

= 0.018 kg/mol

R = 0.4615 kPa·m3/kg·K

Using ideal gas equation,

P × V = n × R × T

But n = mass/molar mass

V = (R × T)/P

V/M = (R × T)/P × m

= (0.4615 × 623)/1.5 × 10^4

= 0.01917 m^3/kg.
