Covalent bonds are strong bonds. Atoms that share pairs of electrons form molecules. A molecule is a group of atoms held together by covalent bonds. A diatomic molecule is a molecule containing only two atoms.
Answer:
<u><em>When balloon filled with the helium gas is left in the car at night along with the decrease in temperature the size of the balloon will get smaller or it will look like little deflated</em></u>.The above observation can be explained on the basis of Charles law:The law states that 'under constant pressure ,the volume occupied by the gas is directly proportional to the temperature of the gas'. (At constant pressure)Temperature desecrate volume will also decreases and vice versa.So, with decrease in temperature at night the temperature of the gas in the balloon will also get decreased due to which the volume of the balloon will also get decreased.
Explanation:
The chemical formula for sodium and sulfur is Na2S I believe...
Answer:
Ionization energy, electronegativity, and lattice energy are the factors that influence the formation of ionic bonds of elements.
Answer:
E. Substance A will be the limiting reactant.
Explanation:
Below is a generic equation for a reaction.
2A + 3B → C + 3DA
According to the balanced equation, the theoretical molar ratio of A to B is 2:3, that is, 2 moles of A react with 3 moles of B.
<em>If I mix 2 units of A, with 6 units of B, which of the following is true?</em>
<em>A. There would be no reaction.</em> FALSE. The reaction will occur until the limiting reactant is over
<em>B. Both reactants will fully react.</em> FALSE.
<em>C. Not enough information given.</em> FALSE.
<em>D. Substance B will be the limiting reactant.</em> FALSE. Substance B will be the reactant in excess because there are 6 moles and only 3 moles are required.
<em>E. Substance A will be the limiting reactant.</em> TRUE.
