Answers:Too lazy to do it for you but here: Metal + Nonmetal = transfer of electrons = ionic Nonmetal + Nonmetal = sharing of electrons = covalent
Answers:some examples of an ionic compound + covalent compound reactions: metal oxide + acid --> water + hydrogen gas metal carbonate + acid --> water + carbon dioxide + salt also, most ionic salts dissolve in covalent compounds because of the solvent's polar nature.
Answers:The ionic balanced equation is 4 H2O + 2 MnO4- + 6 I- >> 2 MnO2 + 3 I2 + 8OH- K is a spectator ion 4H2O + 2 KMnO4 + 6 KI >> 2 MnO2 + 3 I2 + 8 KOH
Answers:1. Determine if the following compounds are likely to have ionic or covalent bonds. a. magnesium oxide, MgO ionic (metal and nonmetal) b. Strontium chloride, SrCl2 ionic (metal and nonmetal) c. Ozone, O3 covalent d. Methanol, CH4O covalent (C and O are nonmetals and H is a metal) *a metal bonded with a nonmetal forms an ionic bond; also, when an element is bonded to itself it forms a covalent bond 2. Identify which 2 of the following substances will conduct electricity, and explain why. a. aluminum foil because Aluminum is a metal and metals are highly conductive & c. potassium hydroxide, KOH, dissolved in water because potassium hydroxide dissolved in water dissociates and forms potassium and hydroxide ions; ions conduct electricity *It CAN'T be b. because sugar does not break up into ions that conduct electricity. 3. How many electrons do the carbon atoms share? Each carbon atom has 4 valence electrons, so each C atom can form 4 bonds. In HCCH, each carbon atom shares 4 electrons and sincethere are 2 of them, there are 8 electrons being shared. 4. Predict whether a silver coin can conduct electricity. What kind of bonds does silver have? The bonds between atoms are metallic which means that the outer electrons are held by weak bonds which can easily dissociate. Dissociation of ions causes electrical conductivity. 5. Describe how it is possible for calcium hydroxide, Ca(OH)2, to have both ionic and covalent bonds. Ca and O can share electrons (covalent bond) with each other or H can take electrons away (ionic bond) from Ca. 6. Explain why electrons are shared equally in ozone, O3, and unequally in carbon dioxide, CO2. In CO2, O is more electronegative meaning that it seeks to pull the electron between itself and carbon more strongly which results in unequal sharing of electrons. In O3, when atoms are bonded together, the electrons are shared equally. 7. Analyze whether dinitrogen tetroxide, N2O4, has covalent or ionic bonds. Describe how you reached this conclusion. N2O4 has covalent bonds because N and O are both nonmetals; nonmetals form covalent bonds. 8. Which element has the greater bond energy, oxygen or nitrogen? (Hint: Which element has more bonds?) Oxygen can form 6 bonds, but Nitrogen can only form 5 bonds, so Oxygen has a greater bond energy.
