the 4 by the element symbol O multiplied by the 3 on the outside of the parentheses
Answer:
<em>6960000 Nickel atoms</em>
<em></em>
Explanation:
radius = 125 pm = 125 x 10^-12 m
diameter of each atom = 125 pm x 2 = 250 pm = 250 x 10^-12 m
span of distance to be achieved = 1.74 mm = 1.74 x 10^-3 m
number of nickel atoms = (1.74 x 10^-3 m)/(250 x 10^-12 m) = <em>6960000 Nickel atoms</em>
<h2>
Answer:</h2>
The water has higher specific heat capacity which affects the lakes largely in such way that the water in a lake changes temperature slowly.
<h2>
Explanation:</h2>
Evaporation is a process of liquid changing its state to gaseous state at any temperature. Water has high specific heat due to the presence of strong hydrogen bonds. Due to which it requires heat in huge amount to raise the water (in large quantity) temperature.
Thus, the molecules will be unable to gain much kinetic energy that result in changing the temperature very slowly.
Answer:
0.02L
Explanation:
Using the formula V1/T1 = V2/T2
Given
V1 = 0.5L
T1 = 25 degrees
T2 = 1 degree
V2 =?
Substitute
0.5/25 = V2/1
Cross multiply
25V2 = 0.5
V2 = 0.5/25
V2 = 0.02L
Hence the new volume will be 0.02L
pyramidal, if you have a molecule kit, i would strongly recommend watching a video of someone using a kit explaining the different shapes and following along. It helps a lot!
