3. Let's try out the atomic mass equation. Suppose you have a mixture of two nitrogen isotopes. For every 1 Nitrogen-15 isotopes, there are 3 Nitrogen-14 isotopes. Determine the abundance of each isotope in this mixture. Predict the average atomic mass of this mixture. Hint: This is NOT the mixture of nitrogen found in nature. You can check your answer by clicking "My Mixture" under isotope mixture. Next, create the mixture described in the problem. 14.50 amu 14.00 amu 14.25 amu 14.75 amu

Below are some objectives. Check if each objective possesses the SMART characteristics. If not, please suggest a revision for that objective. 1. know the meaning of atomic number and atomic mass 2. describe, on the molecular level, the effect of heating and cooling on the motion of molecules of a gas 3. identify different atoms 4. develop and use a model to describe how the total number of atoms does not change in a chemical reaction and thus mass is conserved. 5. understand the formation of ions in ionic compounds

When a chemical reaction occurs, atoms rearrange to form now compounds, but no new atoms are created nor are any destroyed This concept is called conservation of mass. Mass conservation can be seen in a balanced chemical equation where the numbers of each kind of atom are the same on both sides of the reaction arrow. The figure (Figure 1) shows the reaction of element A (lavender spheres) with element B (tan spheres). Write the balanced chemical equation for this reaction in terms of A and B. Express your answer as a chemical equation. When balancing chemical equations with polyatomic ions, it may help to balance the ion as a whole. For example, the ion PO_4^3 can be treated as a unit and balanced in both the reactants and the product, or you can break it down and balance each atom separately. Phosphoric acid reacts with magnesium hydroxide to produce magnesium phosphate and water via the following reaction: Balance the equation, then enter the coefficients, in order, in the answer…

Of all chlorine atoms, 75.771% are chlorine-35. Chlorine-35 atoms have a mass of 34.96885 amu. All other chlorine atoms are chlorine-37 and these have a mass of 36.96590. Calculate the average atomic mass of chlorine. Hint: Percentages must equal 100, so 100 - 75.771 = the missing percent.
