One mole of ice at 0°C is added to two moles of water at 50°C under a constant external pressure of 1 atm. This process is carri

ed out in a thermally insulated vessel, such that no heat can escape the vessel. When equilibrium is reached, all of the ice has melted. Given: Δ H f u s i o n ∘ ( H 2 O a t 0 ∘ C ) = 6.01 k J m o l C p ( H 2 O , l i q u i d ) = 75 J m o l K a) (7 Points) Calculate the final temperature of the mixture (in °C).

Answer:

T2 = 29.79°C

Explanation:

Equliibrium signifies that heat loss = heat gained

Heat gained by Ice;

H = ML

Mass, M = Number of moles * Molar mass = 1 * 18 = 18g

l = 6.01 k J m o l = 334 J/g

C = 4.186 J/g

H =  18(334)

H = 6012

Heat lost by water

H = MCΔT

H = 18 * 4.186 * (50 - T2)

H = 3767.4 - 75.348T2

Since H = H, we have;

6012 = 3767.4 - 75.348T2

- 75.348T2 = 3767 - 6012

T2 = 2245 / 75.348

T2 = 29.79°C

An atom that has 14 protons and 17 neutrons is an isotope of which element?
ale4655 [162]
This is an isotope of silicon since it has 14 protons.  for an element, you can have different numbers of neutrons, however, if you change the number of protons the identity of the element changes.

for example, carbon 14 and carbon 12 both have 6 protons.  The only thing that changed was the number of neutrons which went from 6 to 8.

LUCKY_DIMON [66]

Answer:

[See Below]

Explanation:

Hey~There!

________________________

→ <u>Conversion</u>:

  • 1 ~cm=1000~liters

→ <u>Write out an equation</u>:

  • 129*1000=129000

________________________

→ <u>So your answer would be</u>:

  • 129000~liters
