Answer: C3H4 (Propayne) have a triple bond.
Explanation:
The hydrocarbons which having triple bond are called alkyne. The general formula of alkyne is CnH2n-2. Here, n is number of carbon atoms.
In alkyne, the number of hydrogen atom is 2 less than double the number of carbon atoms.
Thus, the compound C3H4 (Propyne) have a triple bond.
Answer:
The mass of silver is 49 g (0.049 kg).
Explanation:
Initial temperature =
C
Final temperature =
C
Quantity of heat required = 117.5 J
Specific heat capacity of silver = 0.240 J/g
mass of the silver can be determined by;
Q = mcΔθ
Where: Q is the quantity of heat required, m is the mass of substance, c is the specific heat capacity of the substance and Δθ is the change in temperature.
So that,
117.5 = m x 0.240 x (40 - 30)
117.5 = m x 0.24 x 10
= 2.4m
m = 
= 48.9583
m ≅
m = 49 g
The mass of silver is 49 g (0.049 kg).
