Answer:
Q = 1.68 Kcal
Explanation:
∴ m H2O = 12.0 g
∴ T1 = 35°C ≅ 308 K
∴ T2 = 175°C ≅ 448 K
∴ ΔT = T2 - T1 = 175 - 35 = 140 °C
∴ Cp H2O = 1 cal /g.°C
⇒ Q = (12.0 g)(1 cal/g°C)(140 °C)
⇒ Q = (1680 cal)*(Kcal/1000 cal)
⇒ Q = 1.68 Kcal
If it's a pH below six it's blue, if it's a pH between 6 and 7 then it would be purple, if it's above 7 it would be pink or red
If silicon bonded with three oxygen atoms, the crystalline structure called framework will be three dimensional and the silicate minerals will become lighter.

This is because all the others are landforms.
You need to find the mole of glucose by using the formula n = m/Mr. Once you have found the mole you need to follow the stoichiometric process by unknown/known using the co-efficients. Then you need to multiple your answer by the known mole of glucose whoch you have previously calculated. After that you should get the mole of oxygen then you just need to transpose the equation to get m = n×Mr, substitute ypur answers in, remebering you can find your Mr via the period table, you have your answer
