Answer:
n = 0.01302 moles
Explanation:
Pressure = 1.3 atm
Temperature = 31 °C + 273 = 304 K ( Converting to kelvin temperature)
Number of moles = ?
Volume = 250 mL = 0.250 L
These quantities are related by the equation below;
PV = nRT
n = PV / RT
n = (1.3 * 0.250) / (0.0821 * 304)
n = 0.01302 moles
If you combine zinc with apple juice it is toxic.
Answer: 1560632 joules
Explanation:
The change in thermal energy (Q) required to heat ice depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Given that:
Q = ?
Mass of frozen water (ice) = 1kg
C = 4184 J/(kg K)
Φ = (Final temperature - Initial temperature)
= 100°C - 0°C = 100°C
Convert 100°C to Kelvin
(100°C + 273) = 373K
Then, Q = MCΦ
Q = 1kg x 4184 J/(kg K) x 373K
Q = 1560632 joules
Thus, the change in thermal energy is 1560632 joules
Both processes occur in place. No movement is involved in weathering. Chemical weathering involves a chemical change in at least some of the minerals within a rock. Mechanical weathering involves physically breaking rocks into fragments without changing the chemical make-up of the minerals within it.
