Answer:
A metal only replaces a metal, and a nonmetal only replaces a nonmetal. Only a more reactive element can replace the other element in the compound with which it reacts.
Answer:
3.0 L of NH₃
Solution:
The equation is as follow,
N₂ + 3 H₂ → 2 NH₃
According to equation,
67.2 L (3 mole) H₂ at STP produces = 44.8 L (3 mole) of NH₃
So,
4.50 L of H₂ will produce = X L of NH₃
Solving for X,
X = (4.50 L × 44.8 L) ÷ 67.2 L
X = 3.0 L of NH₃
Answer:
The volume occupied by molecules becomes a significant part of the total volume.
Attractions between molecules cause a reduction in volume.
Explanation:
C is wrong. The masses of molecules are constant.
Answer:
Robots will be created to allow scientists to use computer programs.
Explanation:
There are some other answers, but this one is more sufficient. :)
Answer:
2.52atm for sure
Explanation:
We know that:
P1= 2.80atm
T1= 400k
T2= 360k
And we want to find P2= ?
We have an equation: P1/T1 = P2/T2
Multiple both side by T2 to remove it
P2 = 2.52
