Answer:
12.89 moles
Explanation:
Before we solve the question, we have to balance the equation of the reaction first. The balanced reaction will be:
2 NO + 2 H2→ N2 + 2 H2O
There are 180.5g of N2 produced, the number of produced in moles will be: 180.5g / (28g/mol)= 6.446 moles
The coefficient of H2 is two and the coefficient of N2 is one. Mean that we need two moles of H2 for every one mole of N2 produced. The number of H2 reacted will be: 2/1 * 6.446 moles = 12.89 moles
Answer:
Generally, the first ionisation energy increases along a period. But there are some exceptions one which is not an exception
Ans: Decomposition
A decomposition reaction is one in which a compound breaks down into thwo or more smaller compounds.
The given reaction is:
NaHCO3 + H2O → CO2 + NaOH + H2O
In this reaction sodium bicarbonate breaks down to carbon dioxide and water. Therefore, this represents a decomposition reaction.
The answer is 19 ahhahaha
The change in enthalpy associated with the change in the water’s temperature is 1254 J.
<h3>What is specific heat?</h3>
The amount of heat required to increase the temperature of one gram of a substance by one Celsius degree is known as specific heat.
Enthalpy change will be calculated as:
ΔH = -cmΔT, where
m = mass of water = 50g
c = specific heat of water = 4.18J/g°C
ΔT = change in temperature = 28 - 22 = 6 °C
On putting values in the above equation, we get
ΔH = -(4.18)(50)(6) = -1254 J
Hence change in enthalpy of the reaction is -1254 J.
