Explanation:
0.566kg *(1mol/0.197 kg)= 2.87 mol gold
note how the units cancel out, if the units do not cancel out (kg/kg=1) then u did something wrong
Boiling water. <span>heat goes from the burner into the pot which heats the water at the bottom. this hot water rises and cooler water moves down to replace it, causing a circular motion.</span>
The sun . plz give me a nice thank you
Answer:
About 13 cm
Explanation:
We are given that
Length of cylinder,l=15 cm=
1 m=100 cm
h=4 cm=
Horizontal velocity of the existing water stream=
Where 
Using the formula

h'=l-h=15-4=11 cm=
Initial velocity of water stream,u=0

Distance, d=vt
Using the formula


Answer:
Silicon (2.33 g/cm3) < Titanium (4.51 g/cm3) < Nickel (8.9 g/cm³) < Copper (8.96 g/cm³)
Explanation:
Density of copper = 8.96 g/cm³
Density of Nickel = 8.9 g/cm³
Density of Titanium = 4.51 g/cm3
density of silicon = 2.33 g/cm3
The correct order of above metals based on the increasing density is as follow
Silicon (2.33 g/cm3) < Titanium (4.51 g/cm3) < Nickel (8.9 g/cm³) < Copper (8.96 g/cm³)
Thus, copper has the highest density among all.
