Answer:
B
Explanation:
Option be is the only molecular structure with 4 carbon molecules and 10 hydrogen molecules
Answer:
C) 2.99 cm^3
Explanation:
ρ=m/V
V=m/ρ=59.2/19.8=2.99 cm^3
Answer:
False
Explanation:
The term was first "officially" used by French physicist Jean Baptiste Perrin. He technically referenced the works of Avogadro
I would say C. Since the material is getting warmer, the atoms and molecules will start to move fasten and then also create more "messiness" (which is entropy with a less-nice word)
1.2 L of hydrogen can be produced at a pressure of 2 atm and a temperature of 298 K.
<h3>What is an ideal gas equation?</h3>
The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).
Step 1: Write the balanced equation
Mg + 2 HCl ⇒ MgCl₂ + H₂
Step 2: Calculate the moles corresponding to 2.3 g of Mg
The molar mass of Mg is 24.31 g/mol.
2.3 g × 1 mol ÷24.31 g = 0.095 mol
Step 3: Calculate the moles of H₂ produced
0.095 mol Mg × 1 mol H₂ ÷ 1 mol Mg = 0.095 mol H₂
Step 4: Calculate the volume occupied by the hydrogen
We will use the ideal gas equation.
P × V = n × R × T
V = n × R × T÷P
V = 0.095 mol × (0.0821 atm.L/mol.K) × 298 K÷2 atm
V = 1.2 L
