A light-year is the distance light travels in one year. 6 trillion miles
Correct me if I’m wrong
Answer:
You first need to construct a balanced chemical equation to describe the reaction:
KOH + HNO3 ---------> KNO3 + H2O
Work out the no. moles of HNO3 being neutralized:
Moles = Volume x Concentration = (25/1000) x 0.0150 = 0.000375 moles
From the balanced equation the molar ratio of KOH to HNO3 is 1:1 so you also need 0.000375 moles of KOH to neutralise the nitric acid
Now you can work out the volume of KOH required:
Volume = Moles/Concentration = (0.000375)/0.05 = 0.0075 dm^3 = 7.5 cm^3
Answer:

During the day, due to the existence of sunlight, the procedure of photosynthesis elevations over that of respiration. Photosynthesis uses carbon dioxide to produce carbohydrates removing oxygen as a byproduct. During the night, because there is no sunlight, the rate of photosynthesis decreases. This, therefore, drives the rate of respiration to surpass the speed of photosynthesis. In respiration, oxygen is consumed and carbon dioxide is dismissed.
<h3>What is
photosynthesis?</h3>
- Photosynthesis is the process by which manufacturers use sunlight, water, and carbon dioxide to produce oxygen and energy in the form of sugar.
- The primary position of photosynthesis is to transform solar energy into chemical energy and then reserve that chemical energy for prospective use. For the most part, the planet's living designs are powered by this process.
- An illustration of photosynthesis is how plants convert sugar and significance from water, air, and sunlight into energy to grow. Description of photosynthesis is the procedure through which plants use water and carbon dioxide to assemble their food, grow and remove excess oxygen into the air.

<span>When the hexene is treated with an excess of hydrogen gas and a platinum catalyst, the product formed is
hexane.
Hexene is an unsaturated hydrocarbon. Hexene when treated with H2 gas, in presence with Pt catalyst, the double bond is broken. This results in generation of saturated hydrocarbon i.e. hexane. </span>
