Identifying Types of Reactions: For each reaction shown, determine whether it is a synthesis, decomposition, combustion, single replacement, or double replacement (precipitation) reaction. Then balance the equation. Example: Synthesis reaction Mg + S = MgS

Solve these equations:
1. ___Pb2+(aq) + ___ I-(aq) --> ___ PbI2(s)
2. ___Na+___O2 ___Na2O
3. ___Cl2 +___ NaBr ___NaCl + ___Br2
4. ___Ti + ___N2 ___TiN4
5. ___CH4 + ___O2___CO2+ ___H2O
6. ___N2 + ___H2 → ___NH3
7. ___HgO ___Hg + ___O2
8. ___KCl ___K + ___Cl2
9. ___NaCl + ___AgNO3 → ___NaNO3 + ___AgCl(s)
10. ___Ag2O → ___Ag + ___O2
11. ___FeCl2+ ___Zn → ___ ZnCl2 + ___Fe

pretty sure it's false

96.77 amp

explanation:

rl = 250/100 = 2.5 ohms.

egl = 250 + (100 × 0.1) + 2 = 262 v.

at 700 r.p.m., eg2 = 262 × 700/1000 = 183.4 v.

if ia is the new current, then eg2 - 2 - (ia × 0.1) = 2.5 ia

which means this will give ia = 96.77 amp.

answer: the potential energy decreases from 379 j to 243 j

explanation:

for the law of conservation of energy, the total energy in a system must be conserved. the total energy of the system is given by the sum of kinetic (k) and potential (u) energy:

e = k + u

the total energy is e=675 j, and this does not change.

initially, the kinetic energy is k=296 j, so the potential energy is

at the end, the kinetic energy is k=432 j, so the potential energy is

so, we see that the potential energy has decreased from 379 j to 243 j.
