Answer:

C. 33.6L

Explanation:

Based on the reaction, 2 moles of HCl reacts producing 1 mole of hydrogen.

To solve this question we must find the moles of hydrogen produced using the reaction. Then, with combined gas law (PV = nRT) we can find the volume produced:

<em>Moles H2:</em>

3.00 moles HCl * (1mol H2 / 2mol HCl) = 1.50 moles H2 are produced

<em>Volume:</em>

PV = nRT

V = nRT / P

<em>Where P is pressure = 1atm at STP</em>

<em>V is volume = Our incognite</em>

<em>n are moles of the gas = 1.50 moles</em>

<em>R is gas constant = 0.082atmL/molK</em>

<em>T is absolute temperature = 273.15K</em>

<em />

V = nRT / P

V = 1.50mol*0.082atmL/molK*273.15K / 1atm

V = 33.6L

<h3>C. 33.6L</h3>

Statement 2 is correct.
solids moving into solution is a physical change as the core structure of the molecules remain the same. evaporation of water and crystallization of salt are both physical changes as well.
The water does not change it's H2O chemical makeup because salt was dissolved into it.

pochemuha

Answer:

substrate concentration; one-half; the affinity of the substrate-enzyme interaction

Explanation:

The Michaelis constant, Km, refers to the substrate concentration at which a reaction proceeds at one-half of the maximum velocity. This constant most accurately reflects the affinity of the substrate-enzyme interaction.

Silver has a density of 10.5 g/cm³, and gold has a density of 19.3 g/cm³. Which would have a greater mass, 5 cm³ of silver or 5
Vedmedyk [2.9K]

Gold have a greater mass

<h3>Further explanation  </h3>

Density is a quantity derived from the mass and volume  

Density is the ratio of mass per unit volume  

The unit of density can be expressed in g/cm³ or kg/m³  

Density formula:  

\large {\boxed {\bold {\rho ~ = ~ \frac {m} {V}}}}

ρ = density  

m = mass  

v = volume  

  • mass of Silver :

\tt mass=\rho\times V\\\\mass=10.5\times 5=52.5~g

  • mass of Gold :

\tt mass=\rho\times V\\\\mass=19.3\times 5=96.5~g

Determine which intermolecular forces are the dominant (strongest) forces for a pure sample of each of the following molecules b
Ivahew [28]

Answer:

Dispersion forces- Xe, CH4

Dipole-dipole forces-CHCl3

Hydrogen Bonding-HBr, NH3, CH3COOH

Explanation:

Gases and nonpolar molecules posses only dispersion forces. Polar covalent compounds posses dipole- dipole forces. When hydrogen is bonded to a highly electronegative atom, hydrogen bonding results. These account for the arrangement of answers above.
