Explanation:
The salts in drinks help replenish the body's electrolytes lost in sweat. ... The salts in sports drinks help replenish the body's electrolytes lost in sweat. Sodium helps regulate the body's fluid balance and plays a role in muscle contraction, and potassium is also involved in muscle contraction
Answer:
- Increased volume of particles in the container
- greater vibration of particles
Explanation:
At higher temperature, the particles of the gas would be more active and vibrate more, or even have greater collisions. Alex can indicate this in the altered model to depict higher temperature.
Consequently, Charles law gives meaning to why there would be an increased volume of gas in the stable pressurized container, if the temperature were to be increased.
I hope this explanation was clear and concise?
Answer:
The highest molality will be for the NH₄NO₃ . Option 5.
Explanation:
In order to determine which of the salts has the highest molality we must know the moles of each
10 g / 149.89 g/mol = 0.0667 moles NaI
10 g / 166 g/mol = 0.0602 moles KI
10 g / 147.4 g/mol = 0.0678 moles of RbNO₃
10 g / 80 g/ mol = 0.125 moles of NH₄NO₃
To determine molality we convert the mass of solvent (water) from g to kg
800 g . 1kg / 1000 g = 0.8 kg
Molality means the moles of solute in 1kg of solvent
0.0667 moles NaI / 0.8 kg of water = 0.083 m
0.0602 moles KI / 0.8 kg of water = 0.0752 m
0.0678 moles of RbNO₃ / 0.8 kg of water = 0.0847 m
0.125 moles of NH₄NO₃ / 0.8 kg of water = 0.156 m
Answer:
Explanation:
For this problem, you will have to convert moles to atoms. Use Avogadro's number.
