Answer: Scientists are working on nuclear fusion process. Nuclear fusion is the process in which two atomic nuclei combine to form another nuclei. In the process either energy is absorbed or released due to the difference in the mass of reactants and products.
Explanation:
Answer:
H---H and Cl---Cl bonds are broken and H---Cl bonds are formed.
Explanation:
The reaction between Hydrogen and Chlorine to produce HCl is:
⇒
In this reaction the reactants are and .
The product is HCl.
The bonds existing in the reactants are
1) H---H bond in (Non polar and covalent bond)
2)Cl---Cl bond in ( Non polar and covalent bond)
The bonds existing in product is/are:
1)H---Cl bond in HCl (Polar and covalent bond)
So all the chemical bonds in the reactants are broken to produce the chemical bonds in the products
In other words,
The H---H bonds and Cl---Cl bonds are broken to produce H---Cl bonds.
Answer: B. The anion affects the color of the solution more than the intensity of the color.
Explanation:
An ionic bond is gotten when an electron is transferred from a metal atom to a non-metal one. It should be noted that the ionic bonds simply has an anion and a cation.
An anion is formed when a valence election is gained by a non metal while a cation is formed when the metal ion misplaces a valence electron.
The effect of the anion of an ionic compound on the appearance of the solution is that the anion affects the color of the solution more than the intensity of the color.
The correct number of significant figures gotten from the result of (329.5/0.45)-23.2 is infinite because there is no uncertain digit as a result of the answer being 709.022222222 when calculated.
<h3>What is a Significant figure?</h3>
These refers to the digits which contributes to the degree of accuracy of a value and is usually counted starting from the non zero digits. In cases where the zero is between other numbers it is regarded as being significant such as 70.0111 in which the number of significant figures is six.
The result gotten from the expression (329.5/0.45)-23.2 is 709.022222222 which has a recurring decimal thereby making it difficult to calculate the number of recurring decimal.
Therefore it has infinitely many significant figures because there is no uncertain digit.

The answer is gravity:
Explanation: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. Anything that has mass also has gravity.
