Answer:
There is 5720 J of heat released.
Explanation:
Step 1: Data given
Molar mass of CH6N2 = 46.07 g/mol
The heat of combustion of methylhydrazine is −1.30 × 103 kJ/mol
Mass of methylhydrazine = 202.7 grams
Step 2: Calculate number of moles
Moles CH6N2 = mass of CH6N2 / Molar mass CH6N2
Moles CH6N2 = 202.7 grams / 46.07 g/mol
Moles CH6N2 = 4.4 moles
Step 3: Calculate heat released when 202.7 grams of CH6N2 is burned
q = 1300 J/mol * 4.4 moles
q = 5720 J
(Since there is heat released, ΔH = negative)
There is 5720 J released.
Answer:
go with the fourth one because I did that one
Answer:
11.2 M
Explanation:
Given data:
Number of moles = 6.7 mol
Volume of solution = 0.6 L
Concentration /Molarity = ?
Solution:
Molarity:
It is number of moles of solute in to per kg or litters of solution. It can be calculated by the following formula.
Molarity = number of moles / Volume in L
Now we will put the values in formula.
Molarity = 6.7 mol / 0.6 L
Molarity = 11.2 mol/L
Molarity = 11.2 M
Solidity, solidness, denseness, thickness, substance, mass......
Answer:
Prokaryotic is the answer!
Explanation:
I know this because, the nucleolus is absent in the image.
