Answer:
0.06mole
Explanation:
Given parameters:
Volume of balloon = 2.5L
T = 343.5K
P = 66.7kPa; in atm gives = 0.66atm
Unknown:
Number of moles of He = ?
Solution:
To solve this problem, we use the ideal gas equation.
It is mathematically expressed as;
Pv = nRT
where p is the pressure
v is the volume
n is the number of moles
R is the gas constant
T is the temperature
0.66 x 2.5 = n x 0.082 x 343.5
n = 0.06mole

Chemical change. The heat from frying an egg causes the egg's protein to change permanently in texture and in appearance through a process.
Yes because condensed milk and
evaporated milk are similar to one another. However, there won't be the same sweet flavor but the texture is the same.
