Calcium Sulfide is an ionic compound made up of Ca²⁺ and S²⁻.Ca²⁺ is formed as,
Ca → Ca²⁺ + 2 e⁻
These two electrons are accepte by Sulfur as,
S + 2 e⁻ → S²⁻
So, before accepting 2 electrons S was having six valence electrons, after accepting two electrons from Ca it has 8 electrons which are present in four pairs.
Answer: Different parts of the sun rotate at different rates.
Explanation:
The statement that best describes the motion of the sun is that different parts of the sun rotate at different rates.
First and foremost, we should note that the rotation of the sun is on its axis and also the sun isn't a solid. Due to this, its motion will be that there'll be rotation of different part of it at different rates. Assuming the sun was solid, then all of its parts will move together.
Gases have three characteristic properties: (1) they are easy to compress<span>, (2) they expand to </span>fill<span> their containers, and (3) they occupy far more space than the liquids or solids from which they form. An internal</span>combustion engine<span> provides a good example of the ease with which gases can be compressed.</span>
<span>biological reactions that happen within cells while reducing the complex interactions found in a whole cell. Eukaryotic and prokaryotic cells have been used for creation of these simplified environments[1]. Subcellular fractions can be isolated by ultracentrifugation to provide molecular machinery that can be used in reactions in the absence of many of the other cellular components.
Cell-free biosystems can be prepared by mixing a number of purified enzymes and coenzymes. Cell-free biosystems are proposed as a new low-cost biomanufacturing platform compared to microbial fermentation used for thousands of years. Cell-free biosystems have several advantages suitable in industrial applications</span>
Answer:
The length of the cubical container will be 17.206 m.
Explanation:
Amount of carbon dioxide gas generated in year by person = 10,000 kg
1 kg = 1000 g
10,000 kg = 10,000 × 1000 g = 10,000,000 g
Moles of carbon dioxide =
Volume of carbon dioxide gas at STP= V
STP conditions = P = 1 atm , T = 273 K
Using Ideal gas equation ;
Let the side of the cube = a
Volume of the cube =
The length of the cubical container will be 17.206 m.
