You heat 2.53 grams of metallic mercury in air, which produces 2.73 grams of red-orange residue. Assume that the chemical change is the reaction of the metal with oxygen in the air.
What is the mass of oxygen that react? When you strongly heat the red- orange residue, it decomposes to give her back the mercury and release the oxygen, which you collect. What is the mass of oxygen you collected?
A sample of solid silver oxide with a mass of 11.4 grams was reduced to elemental silver by heating under a flow of methane gas, CH4. The reaction produced 10.6 grams of silver.
Write a balanced chemical reaction for the reaction between silver oxide and methane gas. The only products formed in the reaction are solid silver metal, carbon dioxide gas, and water vapor. Include the phases of each reactant and product.
1) Combination Reactions (A+ B à AB): Two elements (or simple
compounds) become one compound.
Mg(s) + O,(g) à MgO(s)
SO((g)
S(s) + O2(g) à
2) Decomposition Reactions (AB à A+ B or ABC à AC + BC): A
compound becomes two or more elements (or simpler compounds).
Н,О() а Н,(g) + 0,(g)
CO,(g)
CUCO;(s) à CuO(s) +
3) Single Replacement Reactions (A+ BC à AC + B): An element (a
metal or a halogen) replaces another element (metal or halogen) in
solution.
Zn(s) + CUSO,(aq) à ZnSO̟(aq) + Cu(s)
NaBr(aq) à NaClI(aq) + Br,(aq)
Cl,(aq) +
4) Double Replacement Reactions (AB + CD à AD + CB): Two elements
"switch" (metals replace each other or hydrogen and a metal replace each
other).
Nal(aq) + Pb(NO,),(aq) à NaNO,(aq) à PbI,(s)
NaOH(aq) ӑ H,О() + NaCl{aq)
НС(аq) +
Reactions may be done in any order. You DO NOT have to indicate
the phase(s) of the products. Record observation(s) and write the
balanced chemical equation in Table 1. Reaction #1 has been done for
you.

- 3.83 For the reaction of nitrogen, N2, and hydrogen, H2, to form ammonia, NH3, a student is attempting to draw a particulate diagram, as shown below. Did the student draw a correct representation of the reaction? If not, what was the error the student made?arrow_forwardWhich of these statements are qualitative? Which are quantitative? Explain your choice in each case. (a) Sodium is a silvery-white metal. (b) Aluminum melts at 660 C. (c) Carbon makes up about 23% of the human body by mass. (d) Pure carbon occurs in different forms: graphite, diamond, and fullerenes.arrow_forwardOn October 21, 1982, the Bureau of the Mint changed the composition of pennies (see Exercise 120). Instead of an alloy of 95% Cu and 5% Zn by mass, a core of 99.2% Zn and 0.8% Cu with a thin shell of copper was adopted. The overall composition of the new penny was 97.6% Zn and 2.4% Cu by mass. Does this account for the difference in mass among die pennies in Exercise 120? Assume the volume of the individual metals that make up each penny can be added together to give the overall volume of the penny, and assume each penny is the same size. (Density of Cu = 8.96 g/cm3; density of Zn = 7.14 g/cm3).arrow_forward
