Represent the following equation pictorially (see Problem 78), using squares to represent A, circles to represent B, and triangles to represent C. A2B3+C2C2B3+A2After you have drawn the equation, use your drawing as a guide to balance it.
A friend is trying to balance the following equation: N2+H2NH3 He presents you with his version of the balanced equation: N+H3NH3 You immediately recognize that he has committed a serious error; however, he argues that there is nothing wrong, since the equation is balanced. What reason can you give to convince him that his method of balancing the equation is flawed?
Steps in Balancing Equations: 1. Write the unbalanced chemical equation, make sure you have followed correctly the rules in writing formulas of compounds 2. Take note of the elements present in the reactant and product side. 3. Count the number of atoms of each element present in the reactant and product side 4. Apply the Law of Conservation of Mass to get the same number of atoms of every element on each side of the equation Balance chemical equations by placing the appropriate coefficients before the symbol or formula Do not change the subscripts of the formula in an attempt to balance the equation as it will change the identity of the components Balance the following Chemical Equations Rewrite the equation and underlined the coefficient added
Wnich of the following statements about chemical equations is (are) /true? 1type='a'> When balancing a chemical equation, you can never change the coefficient in front of any chemical formula. i>The coefficients in a balanced chemical equation refer to the number of grains of reactants and products. i>In a chemical equation, the reactants are on the right, and the products are on the left. i>Wnen balancing a chemical equation, you can never change the subscripts of any chemical formula. i>In chemical reactions, the matter is neither created nor destroyed, so a chemical equation must have the same number of atoms on both sides of the equation.
PLEASE SOLVE THIS ASAPPP. Please disregard the answers already given. Please show your work in the same format though. THANKS. It has to do with molecules, balancing chemical equations, and Stoichiometry.
Please complete and balance the following chemical equations **picture inserted**. Please explain why we end up with 1/2 of elements for some of these and explain how it’s balanced even with the 1/2s. Thank you
Using the balanced equation from Question #8, how many grams of lead will be produced if 2.54 grams ofPbS is burned with 1.88 g of O2? Express your answer to the correct number of significant figures and youmust show all work in the form of dimensional analysis as shown in Lesson 4. (Hint: be sure to work theproblem with both PbS and O2). Grams of lead II sulfide to mol of lead II sulfide. Compare lead sulfide to lead and calculate grams of lead.
Right in the same form as a question please (balancing and stoichiometry)
Beryllium carbide (Be2C) reacts with water (H2O) to produce methane (CH4) and beryllium hydroxide (Be(OH)2). The unbalanced chemical equation for this reaction can be written as the following (Be sure to include a space between formulas and plus sign(+) and formulas and yield arrow -->) . Be2C + H2O → CH4 + Be(OH)2 Balance the chemical equation.
Balance these chemical equations (Use the lowest possible whole number coefficients, and enter 1 if you have 1NaCl for instance). a. SnO2 + H2 --> Sn + H2O b. KOH + H3(PO4) --> K3( PO4 ) + H2O c. Na3(PO4) + HCl --> NaCl + H3(PO4)
For each of the following reactions provide a balanced chemical equation andsuppose exactly 5.00g of each reactant is taken. Determine which reactant is limiting, and calculate what mass of each product is expected. (Assumethat the limiting reactant is completelyconsumed). a. sulfur + sulfuric acid sulfur dioxide + water b. manganese (IV) oxide + sulfuric acid manganese (IV) sulfate + water c.hydrogen sulfide + oxygensulfur dioxide + water d.silver nitrate + aluminum silver + aluminum nitrate
Directions: Balance the following chemical equations:1. SiCl4 + H2O → SiO2 + HCl2. Au2S3 + H2 → Au + H2S3. Al + O2 → Al2O34. Ca3(PO4)3 + H2SO4 → CaSO4 + Ca(H2PO4)25. HClO4 + P4O10 → H3PO4 + Cl2O76. FeS + O2 → FeO3 + SO27. PCl5 + H2O → H3PO4 + HCl8. C2H6O + O2 → CO2 + H2O9. C4H10O + O2 → CO2 + H2O10. Fe + O2 → Fe2O3
