Answer:
Kc of the reaction is 0.9375
Explanation:
Step 1: Data given
Moles of SO2 = 0.40 moles
Moles of O2 = 0.60 moles
Volume = 1.00 L
After the reactio we find 0.30 moles SO3
Step 2: The balanced equation
2 SO2(g) + O2(g) ⇔ 2SO3(g)
Step 3: Calculate Kc
Kc = [SO3]² / ([SO2]²[O2])
Kc = 0.30² / (0.40²*0.60)
Kc = 0.9375
Kc of the reaction is 0.9375
Answer:
The vocabulary terms are in the correct order.
Explanation:
The substances that undergo chang are called <em>reactants</em>. They are what create the products. Reactants are on the left side of the equation while the products are on the right side of the equation. The new substances are called <em>products</em>. In other words, what is produced? The products are produced. The reactant that will be used up first is called a <em>limiting reactant</em>. Why? Because it is what limits the reaction. It determines how much products can be made. The reactant that is left over then, is called the <em>excess reactant.</em> That is what is left in excess and does <u>not</u> determine how much product is made.
Answer: Option D) All of the above.
Explanation:
The ecosystem is made up of living and non-living component relating with their environment. i.e in an ecosystem, plants and animals relate with the food nutrients, climate and weather conditions, soil structure etc
Thus, all of the conditions: a rise in temperature; natural disaster like flooding; the introduction of a new animal species like a predator will definitely change the previously stable condition of an ecosystem.
For this question we use Boyle's law which states the relationship between pressure and volume. At constant temperature, pressure of a gas is inversely proportional to volume of a gas.
PV = k
where P-pressure, V - volume and k - constant
Therefore P1V1 = P2V2
where parameters for 1st instance are on the left side and parameters for the 2nd instance are on the right side.
183 ml x 310 mmHg = 90.6 ml x P2
P2 = 183 x 310 / 90.6
= 626.16 mmHg
pressure required is 626.16 mmHg
Answer:- density of the liquid is 0.21 gram per mL.
Solution:-
From given data, mass of cylinder = 10.4 g
mass of cylinder along with liquid = 11.7 g
So, mass of liquid = 11.7 g - 10.4 g = 1.3 g
Volume of liquid = 6.2 mL
Let's divide the mass by the volume to get the density of the liquid:
density =
So, the density of the liquid is 0.21 gram per mL.
