Answer:
The de Broglie wavelength associated with a baseball is.
Explanation:
De-Broglie wavelength is calculated by using the formula:
.....(1)
where,
= wavelength of particle
h = Planck's constant =
m = mass of particle
v = velocity of particle
We have :
m = 220 g =0.220 kg
velocity of the baseball , v= 69 mile/h
1 mile = 1609.34 m , 1 hour = 3600 s
v =
()
The de Broglie wavelength associated with a baseball is.
Answer:
178.5g of NaCl is the maximum amount that can be dissolved
Explanation:
Solubility is defined as the maximum amount of solute that can be dissolved in aAt 20°C, the solubility of NaCl is 35.7g per 100g of water at 20°C. That means the maximum amount that can be dissolved of NaCl is:
500g water * (35.7g NaCl / 100g water) =
<h3>178.5g of NaCl is the maximum amount that can be dissolved</h3>
The answer to this question would be: Because CoCl2 will change color when humidity changes.
Cobalt chloride or CoCl2 can change its color depends on the humidity. The dry cobalt chloride will have pink color but it will changes into blue if you mix it with water. If the humidity is high, the water in the air might condense into the cobalt chloride and change its color to blue. So high humidity will cause more cobalt chloride turn into blue.
Liquid State
A liquid has a definite volume that can be measured but takes the shape of its container.
