Answer:
Explanation:
1) a, b) A <em>solution</em><em> is a homogeneous mixture of two or more substances</em>. The <em>solute</em><em> is the substance present in a smaller amount</em>, and the <em>solvent</em><em> is the substance present in a larger amount. </em>
c) <em>A </em><em>saturated solution</em><em> contains the maximum amount of a solute that will dissolve in a given solvent at a specific temperature. </em>
2) See picture in attachment.
Answer:
Distance = 200 km
Distance = 204 km
Speed = 77 km/h
Time = 21.42 h
Explanation:
Given:
A.
Speed = 100 km/h , Time = 2 h
Find:
Distance
B.
Speed = 68 km/h , Time = 3 h
Find:
Distance
C.
Distance = 154 km , Time = 2 h
Find:
Speed
D.
Distance = 1500 km speed = 70 km/h
Find:
Time
Computation:
Speed = distance / time
A.
Distance = 100 x 2
Distance = 200 km
B.
Distance = 68 x 3
Distance = 204 km
C.
Speed = 154 / 2
Speed = 77 km/h
D.
Time = 1500 / 70
Time = 21.42 h
It's A. volume
Pressure =
with const depends on the chosen unit of volume
I think so...
H. The atom would no longer be aluminum
If you added a proton to an atom of aluminum it would become a silicone ion
Answer:
The mass of ammonia (NH3) that contains 
hydrogen atoms is 
g.
Explanation:
As 
atoms of hydrogen = 1 mole of the hydrogen atom
Therefore, 
atoms of hydrogen 
moles of the hydrogen atom.
Now, there are 3 moles of hydrogen atoms in 1 mole of ammonia 
.
As the mass of 1 mole of ammonia is 17g, so
when there are 3 moles of hydrogen atoms, then the mass of ammonia = 17 g
Therefore, when there are 
moles of hydrogen atoms, then the mass of ammonia 
g.
Hence, the mass of ammonia that contains hydrogen atoms is g.
