Answer:
False, assuming this is a true/false question.
Explanation:
Energy is converted from one form to another, not destroyed nor created. The suns' energy comes for energy released in nuclear reactions. Energy consumed is converted to another form, such as plant and animal sugars and carbohydrates, where it is stored in the bonds among the elements.
The density of carbon tetrachloride, given the data is 1.59 g/mL
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
with the above formula, we can determine the density of carbon tetrachloride. Details below:
<h3>How to determine the density of carbon tetrachloride</h3>
The following data were obtained from the question:
- Mass of flask = 345.8 g
- Mass of flask + carbon tetrachloride = 703.55 g
- Mass of carbon tetrachlorcide = 703.55 - 345.8 = 357.75 g
- Volume of carbon tetrachlorcide = 225 mL
- Density of carbon tetrachlorcide =?
Density = mass / volume
Density of carbon tetrachlorcide = 357.75 / 225
Density of carbon tetrachlorcide = 1.59 g/mL

Answer:
1.21 × 10⁻³⁰ m
Explanation:
1 mol of photons causing the change in the conformation of 11-retinal has an energy of 164 kJ. We can find out the wavelength (λ) associated with this energy (E) using the Planck-Einstein equation.
E = h . c . λ⁻¹
where,
h is the Planck's constant
c is the speed of light
λ = h . c . E⁻¹ = (6.63 × 10⁻³⁴ J × s) × (3.00 × 10⁸ m/s) × (164 × 10³ J)⁻¹ = 1.21 × 10⁻³⁰ m
It’s dependent on light-dependent products ATP and NADPH which aren’t present at night
