I think the answer would be b because your throat is reacting to the cough?
The theoretical proportion is given by the balanced chemical equation:
2 mol NBr / 3 mol Na OH
Then x mol NaOH / 40 mol NBr3 = 3mol NaOH/2 mol NBr3
Solve for x, x = 40 * 3/2 = 60 mol NaOH.
Given that there are 48 mol NaOH (less than 60) this is the limitant reactant and the other is the excess reactant.
Answer: NBr3..
Battery represents a simple machine
A. They are the most destructive earthquake waves.
D. They can move in a rolling pattern through rock, like an ocean wave.
Explanation:
Surface waves are seismic waves that cause the most destruction during an earthquake.
Rayleigh waves are known to cause rolling pattern of rocks just like an ocean waves.
- Seismic waves are elastic waves that notably transmits energy.
- They usually accompany earthquakes.
- There are two broad categories of these waves.
- Surface and body waves.
- Seismic surface waves are low frequency and long wavelength waves.
- They travel very close to the surface.
- They are made up of Love and Rayleigh waves.
- Love waves travels laterally in a horizontal fashion.
- Rayleigh waves rolls like ocean waves in the ground.
- The bulk of the destruction caused during an earthquakes is due to these waves.
- They are the last waves to arrive a seismic station

Answer: it would be 0.026 moles
Explanation: PV=nRT, P is the pressure of gas, V is the volume it occupies n is the number of moles of gas present in the sample, R is the universal gas constant which is equal to 0.0821 atm L/mol K and T is the absolute temperature of the gas
