Atomic mass..so the answer is D
Molar mass <span>CH2BrCH2Br = 188.0 g/mol
1 mole ---------- 188.0 g
</span>0.500 moles ----- ?
mass = 0.500 * 188.0 / 1
= 94.0 g
Answer C
hope this helps!
There doesn't seem to be a question. I'm going to take a wild guess and say that what you want is a balanced equation.
Here is the unbalanced equation
NH4NO3(s) ===> N2(g) + O2(g) + H2O(g) Start by balancing the N2 on the left
2NH4NO3(s) ===> N2(g) + O2(g) + H2O(g) Now balance the hydrogen
2NH4NO3(s) ===> N2(g) + O2(g) + 4H2O(g) You need 8 Hs
Go for the Oxygens.
They are balanced. There's 6 on the left and 4+2 on the right.
Using the ideal gas equation:
PV = nRT, we can form:
V/n = constant
Thus,
V₁/n₁ = V₂/n₂
n₂ = 2.3 x 85.5/50.5
= 3.89 moles
Answer: <span>Ethanoic acid (CH3COOH)
Reason:
Chemical property of substance depends upon the functional group associated with the system. Compound with same functional group will have similar chemical properties.
In present case, </span>propanoic acid has an acidic functional group (-COOH). Also, ethanoic acid has an acidic functional group (-COOH).
On the other hand, propanal and1-propanol have aldehydic (-CHO) and alcoholic (-OH) functional group. <span>Propane is a pure alkane and will have minimum chemical reactivity.
Due to this, propanoic acid will have chemical properties similar to ethanoic acid. </span>
