Answer : The image is attached below.
Explanation :
For 
:
Molar mass, M = 48 g/mol
Mass, m = 24 g
Moles, n = 
Number of particles, N = 
For 
:
Molar mass, M = 17 g/mol
Mass, m = 170 g
Moles, n = 
Number of particles, N = 
For 
:
Molar mass, M = 38 g/mol
Mass, m = 38 g
Moles, n = 
Number of particles, N = 
For 
:
Molar mass, M = 44 g/mol
Moles, n = 0.10 mol
Mass, m = 
Number of particles, N = 
For 
:
Molar mass, M = 46 g/mol
Moles, n = 0.20 mol
Mass, m = 
Number of particles, N = 
For 
:
Molar mass, M = 20 g/mol
Number of particles = 
Moles, n = 
Mass, m = 
For 
:
Molar mass, M = 44 g/mol
Number of particles = 
Moles, n = 
Mass, m = 
For unknown substance:
Number of particles = 
Mass, m = 8.5 g
Moles, n = 
Molar mass, M = 
The substance is .
Answer: To find the energy of a photon you want to use this equation: E=hf
Explanation: E is the energy of the photon in Joules; h is Planck's constant, which is always 6.63*10^-34 Joule seconds; and f is the frequency of the light in hertz.
Answer:
Yes.
Explanation:
Yes, commodities in one sector should be used in another sector because scientist invented methods in which one commodity is used in several sectors for the production of new products. Corn was used for the production of ethanol which causes the shortage of corn that was available to consumers during and after the drought condition of 2012. Due to drought, the production of corn decreases and shortage of it occurs.
Answer:
