Answer:
Sodium Chloride is salt
Explanation:
Basically, its used to help absorb and transport nutrients, its also used to help blood pressure along with maintaining the right balance of fluid. These will all be helpful to our bodies and environment.

Answer:
98.4 kPa
Explanation:
Step 1: Given and required data
- Partial pressure of water vapor at 60°C (pH₂O): 19.9 kPa (this info is tabulated)
- Partial pressure of nitrogen (pN₂): 53.0 kPa
- Partial pressure of helium (pHe): 25.5 kPa
Step 2: Calculate the total pressure of the gaseous mixture
The total pressure of the gaseous mixture (P) os equal to the sum of the partial pressures of the gases that form it.
P = pH₂O + pN₂ + pHe
P = 19.9 kPa + 53.0 kPa + 25.5 kPa = 98.4 kPa
Answer:
25.2°C
Explanation:
Given parameters:
Energy applied to the water = 1000J
Mass of water = 50g
Final temperature = 30°C
Unknown:
Initial temperature = ?
Solution:
To solve this problem, we use the expression below:
H = m c Ф
H is the energy absorbed
m is the mass
c is the specific heat capacity
Ф is the change in temperature
1000 = 50 x 4.184 x (30 - initial temperature )
1000 = 209.2(30 - initial temperature)
4.78 = 30 - initial temperature
4.78 - 30 = - initial temperature
Initial temperature = 25.2°C
