Searching for this question, I found the options on the internet.
"1.<span />Two atoms share electrons so they can fill their outer shells<span>2.The constant motion of electrons and the creation of charge imbalances bonds two molecules together3.A hydrogen atom with a slight positive charge is attracted to a negative charge of another molecule or atom4.One atom loses one or more electrons and the other atom gains one or more electrons"
The correct answer would be number 1. A covalent bond is achieved when two atoms share electrons from their outer shell so that they have a full outer shell leading to the electronic configuration balance they need.</span>
The equation is L = m/M
First, covert 10. grams of AgNO3 to moles which is 0.059 moles.
Divide 0.059 moles by 0.25M which is 0.24 liters.
<span>The correct answer is 1. compound. There are three elements and not just one so it's not element. Mixtures wouldn't have the same properties that you described but these do so it's a compounds. Solution is not a solid thing but rather a liquid one. The two samples are therefore compounds.</span>
The amount of chemical energy a substance has is influenced by its structure and the bond the substance has.
Some bond is release energy when broken, other bond need some energy to break. The structure will also influence the chemical energy.
One of substance with high chemical energy is adenosine triphosphate which was used as energy source in a living organism. The phosphate bond in this molecule worth about 30.5 kJ/moles
Mass of iodine solid produced = 1.6 g
Iodine solid has a molecular formula : I2
Atomic mass of iodine = 126.904 g/mol
Therefore, molar mass of I2 solid = 2* 126.904 = 253.808 g/mol
Number of moles of a given substance is the ratio of its mass to the molar mass
# moles of I2 solid = mass of I2 solid/molar mass = 1.6 g/253.808 = 0.00630 moles
Hence, the # moles of iodine solid produced is 0.00630 moles
