Answer:2H₂+ O₂→ 2H₂O the reactants are 2H₂ and O₂ ... if the theoretical yield is 95 g of water after the chemical reaction you may have only 45g of water
i think
Explanation:
Atoms of particles are so small that they cannot be divided further by any physical means.
<h3>What are atoms?</h3>
According to John Dalton, atoms are the smallest, indivisible particles of elements.
However, it was later found out that chemically, atoms consist of protons, neutrons, and electrons.
Thus, the indivisibility of atoms that John Dalton was referring to must be that of physical division.
In other words, the particles of atoms are so small that dividing them further using physical means is absolutely impossible.

energy to raise temperature is 590 J
Given:
mass of silver sample = 0.5 kg
initial temperature = 200 k
final temperature = 205 k
specific heat of silver = 236 j/kgk
To Find:
energy to raise temperature
Solution: The heat energy required to raise the temperature of of a substance through is called its specific heat capacity.
Q = cmΔt
where c= constant of proportionality, called specific heat capacity of the body
Q = mass x specific heat x ∆t
= 0.5 x 236 x ( 205-200 )
= 590 J
So, energy to raise temperature is 590 J

Answer:
The correct answer is 639 L H₂
Explanation:
We use the ideal gas equation:
We have the following data:
n = 28.3 mol
T= 297 K
P= 1.08 atm
R= 0.082 L.atm/K.mol (gas constant)
We introduce the data in the gas equation to calculate the volume (V):
PV=nRT
⇒V =nRT/P = (28.3 mol x 0.082 L.atm/K.mol x 297 K)/(1.08 atm) = 638.2 L ≅ 639 L
Therefore, the correct option is 639 L H₂
