When there are equal numbers of atoms represented on both the reactant and the product sides,...
State the number of atoms of each element on the reactant and on the product sides of the following equations: a. CH4(g) + 2O2(g) àCO2(g) + 2H2O(g) b. 4P(s) + 5O2(g) à P4O10(s) c. 4NH3(g) + 6NO(g) à 5N2(g) + 6H2O(g) d.6CO2(g) + 6H2O(l) à C3H12O6(aq) + 6O2(g)
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...
An ordinary (fair) die is a cube with the numbers 1 through 6 on the sides (represented by painted spots). Imagine that such a die is rolled twice in succession and that the face values of the two rolls are added together. This sum is recorded as the outcome of a single trial of a random experiment. Compute the probability of each of the following events. Event A: The sum is greater than 8. Event B: The sum is divisible by 4 or...

please provide a detailed explaination and H'Nmr and C’nmr analyiys for both the reactant and product. please indicate the the ppm, spliting, chemical shifts and what they can tell is Exp.2 Epoxidation of Cholesterol with MCPBA МСРВА CHCI НО.
Problem 2: Below are several chemical equations. For each equation, identify which atoms are oxidized and which atoms are reduced. It is possible to have a type of atom that is both oxidized and reduced in the same chemical process. (How? Assign oxidation numbers to each element on both sides of the equation. If the number goes up, the atom is oxidized. If the number goes down, it's reduced.) a. N2(g) + 2 O2(g) → 2 NO2(g) b. CH4(g) +...
Objective Find the ratio of moles of reactant to moles of a product for the reaction below. Compare mass and mole amounts of reactants to determine the amount of products that can be/are made. Background Chemical reactions are represented by balanced chemical equations. Proper interpretation of an equation provides a great deal of information about the reaction it represents and about the substances involved in the reaction. For example, the coefficients in a balanced equation indicate the number of moles...

How many oxygen atoms are on the reactant side of this chemical equation? K2SO4(aq)+Pb(NO3)2(aq)→2KNO3(aq)+PbSO4(s)
1. 2. 3. Balancing Oxidation-Reduction Reactions 1. Assign oxidation numbers. 2. Separate into oxidation and reduction half reactions. 3. Balance each half reaction using the following steps: a. Balance all elements except oxygen or hydrogen. b. Balance oxygen by adding H20. c. Balance hydrogen by adding H*. d. Balance charge by adding electrons: Electrons go on the RIGHT (product side) for OXIDATION reactions. Electrons go on the LEFT (reactant side) for REDUCTION reactions. e. In BASIC solution, do this additional...
