Answer: when an ionic compound dissolves in water, the positive ends of the water molecules are attracted to the anions and the negative ends are attracted to the cations.
Hydrogen Chloride (HCl) is a compound which forms an acidic solution when dissolved in water.
Hope it helps :)
Explanation:
Answer:
563712.04903 Pa
Explanation:
m = Mass of material = 3.3 kg
r = Radius of sphere = 1.25 m
v = Volume of balloon = 
M = Molar mass of helium = 
= Density of surrounding air = 
R = Gas constant = 8.314 J/mol K
T = Temperature = 345 K
Weight of balloon + Weight of helium = Weight of air displaced
Mass of helium is 6.4356 kg
Moles of helium
Ideal gas law
The absolute pressure of the Helium gas is 563712.04903 Pa
Given conditions:
height of object = 7.5cmdistance of object from mirror = 14 cmfocus length = -7 cmimage distance = ?
Using mirror formula:
1/(focus length) = 1/(object distance) + 1/(image distance)
or, -1/7 = 1/14 + 1/(image distance)
or, image distance = -4.66cm (the image formed is a virtual image)
Also, magnification of image is:
image height /height of object = - image distance /object distance
or, image height = - image distance / object distance * height of object
or, image height = -(-4.66) / 14 * 7.5 = 2.49 = 3(nearest whole number)
V=IR however in this case we will rearrange it into R= V/I. Which leads to R=15.0/0.30. And your answer becomes 50.
At the top, due to the fact that POTENTIAL energy is Stored energy.
