Activation energy is required to start a reaction.

Answer: activation

<u>Explanation:</u>

Activation energy is the minimum energy the molecules required in order to collide with each other. Chemical reactions require a particular energy to start its function. The reaction only occurs when the products are more stable than the reactants.

This energy can be in the form of kinetic or potential energy. When the molecules collide, the molecules' kinetic energy used to stretch, sometimes bend and possibly break bonds, causing chemical reactions. Faster the objects move, more the kinetic energy it possesses.

Explanation:

moles of NH₃ = 11.9g/17.03 g/mol = 0.699 mole

moles of CN₂OH₄ = 1/2(0.699) mole =0.349 mole

Theoretical yield of CN₂OH₄ = (0.349 mole)(60 g/mole) = 20.963 grams

%Yield = Actual Yield/Theoretical Yield x 100%

= 18.5g/20.963g x 100% = 88.25%

A cylinder of compressed gas has a volume of 350 ml and a pressure of 931 torr. What volume in Liters would the gas occupy if al

hodyreva [135]

Answer:

$0.384\ \text{L}$

Explanation:

$P_1$ = Initial pressure = 931 torr = $931\times \dfrac{101.325}{760}=124.12\ \text{kPa}$

$P_2$ = Final pressure = 113 kPa

$V_1$ = Initial volume = 350 mL

$V_2$ = Final volume

From the Boyle's law we have

$P_1V_1=P_2V_2\\\Rightarrow V_2=\dfrac{P_1V_1}{P_2}\\\Rightarrow V_2=\dfrac{124.12\times 350}{113}\\\Rightarrow V_2=384.44\ \text{mL}=0.384\ \text{L}$
