I think thats the answer but feel free to check my work
Answer:
5.00 moles..hope it helps
Answer:
the volume will increase
Explanation:
The kinetic energy of gas molecules depend upon the temperature . If temperature is increased , the molecules will move faster . When temperature is decreased , they move slower .
Hence when more molecules are added to a gas without changing its temperature , the velocity of gas molecules will remain unchanged .
Since pressure is also constant , it is volume which will be increased .
It can be explained from universal gas formula as follows
PV = nRT
P , R and T is constant ,
V ∝ n
Volume is proportional to n which depends upon number of molecules .
So volume will increase if number of molecules increases .
Answer:
The force of gravity between them would be doubled.
Answer:
A. 2Cu(s) + S(s) → Cu₂S(s)
B. 2C₈H₁₈(g) + 25O₂(g) → 16CO₂(g) + 18H₂O(g)
C. 2SO₂(g) + O₂(g) → 2SO₃(g)
Explanation:
A. Let's think the reactants:
Cu and S
The product is: CuS
Equation: 2Cu(s) + S(s) → Cu₂S(s)
B. The reactants are:
O₂ and C₈H₁₈
The products are: water and CO₂
This is a combustion reaction: 2C₈H₁₈(g) + 25O₂(g) → 16CO₂(g) + 18H₂O(g)
C. Reactants: SO₂ and O₂
Products: SO₃
Equation: 2SO₂(g) + O₂(g) → 2SO₃(g)
