348 g of water starting at 4.0°Celsius is heated until his temperature is 37°Celsius. Calculate the amount of heat energy needed
attashe74 [19]

Answer:

48.049 kJ or 48049 J

Explanation:

Hello again.

So we know the formula q = mc\Delta t. c is the heat capacity but this time, it is not given. However, water has a very well known heat capacity which is 4.184 J/(g°C). This is in fact the number we refer to a calorie which is the amount of energy you burn that can raise the temperature of 1g of water by 1°C. So, plugging in values, you get the above. But double check if I am wrong.

Airida [17]

Answer:

Callie expect 600 molecules of CO2 to have been released as a waste during the same amount of time.

Explanation:

During cellular respiration 1 molecule of glucose undergoes oxidation to form 6 molecules of CO2 as a waste product.

     According to the question callie determined that the germinating corn seed had utilized 100 molecules of glucose.

    So 100 molecules of glucose will release 100×6=600 molecules of CO2 as a waste product.

An equilibrium mixture of O2, SO2 and SO3 contains equal concentrations of SO2 and SO3.
AleksAgata [21]

Answer:

[O₂(g)] = 0.0037M

Explanation:

            2SO₂(g) + O₂(g) => 2SO₃(g)

Conc:   [SO₂(g)]   [O₂(g)]     [SO₃(g)]  and  [SO₂(g)] = [SO₃(g)]

Kc =  [SO₃(g)]²/[O₂(g)][SO₂(g)]² => Kc = 1/[O₂(g)] = 270 if [SO₂(g)] = [SO₃(g)]

∴ [O₂(g)] = (1/270)M = 0.0037M
