The concentration is 5 g/L.
Concentration = mass/volume = 10 g/2 L = 5 g/L
C. 4 decorated cupcakes.
Because 12 divided by 3 = 4, so you can have 4 cupcakes each with 3 cherries
<span>1.) Adding CO2 creates a stress on the equlibrium system.which means there will be exothermic reaction in other words more product (i:e H2CO3) will be formed.
</span><span>The equilibrium will shift to the right to offset the applied stress.
</span>
Hence more H2CO3 will be produced. Option A is correct.
2.) Rate = <span>[SO2]2 x [O2] / [SO3]2.
</span>
Hence option C is correct.
Hope this helps!
The correct answer among the choice presented above would be option C. The solution that will have the greatest freezing point depression is <span>11 g of calcium fluoride (CaF2). This is because it has higher concentration among other solutions. Also, when it ionizes 3 ions are formed.</span>
Based on the given chemical equation, the value of coefficient that is used in the reaction before each molecule is 1.
<h3>What is balanced equation?</h3>
Balanced chemical equations are those equation in which each element is present in equal amount on both side of the chemical reaction.
Given chemical reaction is:
BaO₂ + H₂SO₄ → H₂O₂ + BaSO₄
Above reaction is balanced as all elements are present in equal amounts on both sides. So, the value of coefficients is 1.
Hence the required coefficients is 1.
