Answer:

14.3°C

Explanation:

q = m * c * ΔT

ΔT = \frac{q}{mc}

the specific heat of iron (c) is 0.450 J/g°C

ΔT = \frac{q}{mc} = \frac{225J}{35g * \frac{0.450 J}{g C} } = \frac{225J * g * C}{35g * 0.450J}

cancel out stuff now

ΔT = \frac{225C}{35 * 0.450} = 14.3

Refer to the following balance equation : 2c2h6 + 7o2 = 4co2 + 6 h20. How many moles of c2h6 will combust completely with 2.0 mo
n200080 [17]
1. From the balanced equation given above, the ratio of the number of moles of the hydrocarbon and oxygen is equal to 2/7. Given that there are 2 moles of oxygen,

    moles hydrocarbon = (2 moles O2)(2 moles HC / 7 moles oxygen)

Simplifying,
   moles HC = 4/7 or 0.57 moles HC

Answer: 0.57 moles HC

2. The calculation for the mass of water is shown below with the dimensional analysis and conversion factors,

  (30 g C2H6)1 mole C2H6/30 g C2H6)(6 molesH2O/2 moles C2H6)(18 g H2O/1 mole C2H6)


Simplifying,
     mass  = 54 grams of water
