Answer:
the answer should be c
Explanation: why because 37/19 k toward 0+1e +37/18 AR is equivalent to the beta decay and it describes the best beta decay in the formula.
Answer:
Absolute zero temperature: Absolute zero is the temperature at which a substance have very low internal energy or in other words no heat energy in the particle.
Explanation: The temperature is very low and the particles are very cold. On cooling, speed of particle decrease. On the Celsius scale, - 273.15 is the absolute zero and on the Kelvin scale, 0 k is the absolute zero. On absolute zero temperature, the movement in the particles occurs at very low speed near to zero.
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:
Stirring will help cool a hot drink because it speeds up the process of convection by bringing the hottest liquid at the bottom to the top
