Among ammonia, neon and copper,
Ammonia is a compound
Neon is an element
Copper is an element
Ammonia is a compound as it is made up of nitrogen and hydrogen that combines in a ratio that is 1 :3 to form 1 mole of ammonia.
And copper and neon are element as they consist of only one type of atom.
So the answer is that Ammonia is a compound
Neon is an element
Copper is an element
Hello!
The volume of the gas when its pressure is increased to 880 mm Hg is
88,64 mLThis question can be easily answered using the
Boyle's Law, which states that as pressure increases, the volume is lower. It can be expressed in a mathematical way as follows:
So, from this equation we can clear V₂ to find the volume at 880 mm Hg:
Have a nice day!
The amount of seawater that will be displaced would be 1.3274 x
<h3>Density and volume</h3>
Density = mass/volume.
Since a floating object displaces its own weight, a 4247 tons ship will also displace the same amount of water.
4247 tons of seawater = 3.8528 x g
volume of 3.8528 x g seawater = mass/density = 3.8528 x g/1.025 = 3758829268.29 cubic centimeter.
3758829268.29 = 132741.80 or 1.3274 x

For [Ca +2 ]:
0.0010 mol/l · 0.05 l =
For [ SO4 -2 ] :
0.01 mol/l · 0.05 l =
Cumulative volume:
50 ml + 50 ml = 10 ml = 0.1 l
[Ca +2 ] =
[SO4 - 2] =
