Answer:
C
Explanation:
Please see the attached picture for the explanation.
<u>Le Châtelier's principle</u><u>:</u>
When a stress is applied to a system at equilibrium, the system will respond by shifting in the direction that opposes/ minimizes the effect of the stress.
• This stress could be the addition or removal of a product or reactant, changes in the concentration of the products or reactants, or a change in temperature.
☆ Why can heat be written on the same side of the products when the reaction is exothermic?
• Exothermic means that heat is released, thus heat can be treated as a product.
• I like to remember it as Exothermic → Exit
Explanation:
An atom is the smallest particle of an element which can exist freely in nature...
7.38mol Fe(6.022x10^23 over 1 mol)= 44.4x10^23 but now you need to move the decimal because 44 isn’t between 1 & 9.
4.44x10^24
<span>Density is a value for
mass, such as kg, divided by a value for volume, such as m3. Density is a
physical property of a substance that represents the mass of that substance per
unit volume. We calculate the density using the equation
Density = mass / volume
The units asked for the density would be </span>penny<span>weights per peck. </span> The conversion factors are as follows:
1 pennyweight (pw) = 1.55 grams
<span>1 hogshead (hh) = 238.5 liters </span>
<span>1 peck = 9.091 liters
</span>
We calculate as follows:
mass = 54.424 kg ( 1000 g / 1kg ) ( 1 pennyweight / 1.55 g ) = 35112.26 pennyweight
volume = <span>0.250 hogsheads ( 238.5 L / 1 hogshead ) ( 1 peck / 9.091 L ) = 6.56 peck
Density = </span>35112.26 pennyweight / 6.56 peck = 5353.55 pw / peck
