Answer:
∴ Q = -7.52kCal
Explanation:
Using the formula for specific heat capacity:
Q = mcΔT
where ΔT = change in temperature (final - initial) = (0 - 100)°C = -100°C
m = mass (g) = 75g
c = specific heat capacity = 4.2 J/g°C in water
⇒ Q = 75 × 4.2 × -100
= -31,500J
But 1J - 0.000239kCal
<u>∴ Q = -7.52kCal</u>

Let me know if I can be of further assistance.
Answer:
A bonding that occurs between high electronegative atoms such are N, F, O and H atoms, is called a hydrogen bond. Hydrogen bond is a very strong bond. (C)
If hydrogen bonds are not formed between H atoms and N, F, O atom, then the atoms interact through dispersion forces (also known as london dispersion forces). Dispersion forces are weak and they are temporary forces formed by overlapping of orbitals. (B)
the answer you have chosen is correct
Answer:
LEAN DOUGHS
Explanation:
A lean dough is a dough low in fat and sugar. Hard crust breads and rolls such as French and Italian breads and pizza crusts. Other white and whole wheat breads and dinner rolls. These are higher in fat and sugar and sometimes contain eggs and milk solids, because they are richer, they have a softer crust.
