Answer:
pour in hot water and It will disolve
Group 2 elements are the alkaline earth metals
Answer:
295.96 K ( = 22.81 degrees C)
Explanation:
PV = n RT R = .082057 L-Atm / (K-Mol) n = 3.5 P = 1 atm V = 85 liters
(1)(85) = 3.5 (.082057)(T)
solve for T = 295.96 K
Answer:
206 c
Explanation:
Use the Charles' Law because you have the volume and temperature given.
V1 / T1 = V2 / T2
Let's list the given:
V1 = 0.668 L
V2 = 0.942 L
T1 = 66.8 C (339.8K)
Convert all Celsius temps to Kelvin. Just add 273.
Asked: T2
Derive the formula for T2.
T2 = V2T1 / V1
= (0.942)(339.8) / 0.668
= 479K
Since the temp should be in C, just subtract 273 from 479K.
The answer is 206 C.
