• ## Which statement best explains why a carbon atom can bond easily with other atoms? It is an ion. It is an organic element. It has four valence electrons. It forms hydrogen bonds.

Answer : The mass of produced will be, 6.16 grams. Explanation : Given, Mass of = 14 g Mass of = 56.70 g Molar mass of = 100 g/mole Molar mass of = 36.5 g/mole Molar mass of = 44 g/mole First we have to calculate the moles of and . Now we have to

• ## Which shows the correct relationship? A.) Eo cell > 0 = nonspontaneous reaction B.) Eo cell > 0 = spontaneous reaction C.) Eo cell = 0 = nonspontaneous reaction D.) Eo cell Answer: B.) > 0 = spontaneous reactionExplanation:The standard emf of a cell is related to Gibbs free energy by following relation: = gibbs free energyn= no of electrons gained or lostF= faraday’s constant = standard emfwhen = +ve, reaction is non spontaneous= -ve, reaction is spontaneous= 0, reaction is in equilibriumThus reaction is spontaneous when = +veThus reaction is non spontaneous when = -veThus reaction is in equilibrium when = 0.

• ## From your knowledge about the distribution of electrons in the levels and from the atomic number (in parentheses), indicate the most likely charge on the ion when this atom forms an ion. (Remember the 2, 8, 18 level distribution.) Answer Choices: 0 -1 +1 -2 +2

The equation that shows  acts as the acid is Further Explanation: Acids and bases can be defined in many ways based on different theories, which are as follows: 1. Arrhenius theory: According to this theory, acid is defined as the one which produces hydrogen or hydronium ions in a solution, while the base is defined

• ## How many electrons can exist on the following energy levels

Hi! Great first step would be to understand the scenario (in my opinion). So two great ways would be to draw a picture or rephrase it. If something else works, do that! You just need to “see” the situation so that you can take some away from it. Then I think a good next step

• ## This one question is on fotoeletric effect. Does the kinetic energy of the ejected electrons from metal depends on the intensity of radiation that is hitting that metal.
