Answer:
The height of Everest. Controversy over the exact elevation of the summit developed because of variations in snow level, gravity deviation, and light refraction. The figure 29,028 feet (8,848 metres), plus or minus a fraction, was established by the Survey of India between 1952 and 1954 and became widely accepted.
Answer:
4.5 M
Explanation:
70.0 ml was mixed in 3.00 M of Na2SO4
30.0 ml was mixed in 1.00 M of NACL
The first step is to convert 70 ml to liters
= 70/1000
= 0.07 liters
The formular for molarity is
moles/liters
The number of moles in Na2S04 can be calculated as follows
Let y represent the number of moles
3M= y moles/0.07
= 3×0.07
= 0.21 moles
Since Na2So4 has 2 moles of Na then the number of moles is
= 2×0.21
= 0.42 moles
Convert 30ml to liters
= 30/1000
= 0.03 liters
The number of moles in Nacl can be calculated as follows
Let y represent the number of moles
1M= y moles/0.03
= 1×0.03
= 0.03 moles
Since Nacl has 1 mole of Na then the number of moles is
= 1 × 0.03
= 0.03 moles
Therefore the final Na+ can be calculated as follows
Total moles = 0.03 moles + 0.42 moles
= 0.45 moles
Total liters= 0.07 liters + 0.03 liters
= 0.1 liters
Na+ = 0.45/0.1
= 4.5 M
Hence the final Na+ in the solution is 4.5 M
<h2><em>Summary: Jupiter is the largest and widest planet in the solar system. Jupiter's moon name is Europa. Jupiter only has one 79 moons that we know of. Jupiter is the 5th planet from the sun.Jupiter’s mass is 318 times larger than Earth.A year on Jupiter is equal to 11.9 Earth Years.</em></h2>
A liquid takes 10.14 x 10^6 J of energy to boil 28.47 kg at 298 K. Using the Latent heats of vaporization of some of the substances:
Acetone: 538,900 
Ammonia: 1,371,000
Propane: 356,000
Methane: 480,600
Ethanol: 841,000
Calculating the latent heat of vaporization of the given substance:
Heat required = 
Mass of the substance boiled = 28.47 kg
Latent heat of vaporization =
So the substance boiled is propane.
