<h2>Nucleosynthesis.</h2>
Explanation:
A. the Big Bang occurred; the Big Crunch occurred
Nucleosynthesis is the process by which new atomic nucleus are formed from pre-existing protons and neutrons.
According to cosmic theories, the nucleosythesis began one minute after the occurrence of Big bang and will end with the big Crunch.
The Big bang theory describes all the processes by which the universe came into existence while the big crunch theory explains how universe will come to an end. A
Bef2 is the compound that has the most covalent character. Whichever element has the greatest electronegativity has the least difference and most covalent character.
Answer:
The calculated concentration of sodium thiosulphate solution will be less than the actual value.
Explanation:
When IO3^2- solution is added to KI solution, I2 gas is released ,then sulphuric acid is now added to facilitate reduction. In order to prevent the escape of iodine (I2) gas ,the solution must immediately be titrated with thiosulphate.
If the solution is not immediately titrated with thiosulphate, the concentration of iodine available in the system decreases. When this occurs, it will also cause a decrease in the amount of iodine available to react with thiosulphate thus decreasing the concentration of thiosulphate obtained from calculation
True.
SF are used for simplifying figures in a measurement to produce a more accurate reading.
Answer:
