When u add the solution to the chemical's
Answer:
Powerade has the most dissolved ions, followed by Gatorade and lastly vitamin water
Explanation:
How conductive a certain solution is, is based on the kind of ions that are present or dissolved in the solution. Hence, we have it that, the higher the concentration of the ions that are present in a solution, the better it will conduct.
There is thus, a direct relationship between what is dissolved or the kind of present ions and how conductive the solution is.
A solution with more dissolved ions is a better conductor of electricity and thus has a conductivity value that is higher
Thus, we can conclude that Powerade has more dissolved ions, Gatorade has less and Vitamin water has the least
Answer:
2.19moles
Explanation:
mole = mass ÷ molar mass
Molar Mass of the compound, C135H96O9NS =
12(135) + 1(96) + 16(9) + 14 + 32
= 1620 + 96 + 144 + 14 + 32
= 1906g/mol
Next, we calculate the mass percent of Oxygen in the compound
O9 = 16(9) = 144g/mol
144/1906 × 100
= 0.0755 × 100
= 7.55%
This means that there are 0.0755g of Oxygen in 1 mole of the coal compound.
Hence, in 29.1 moles of coal, there would be 29.1 × 0.0755
= 2.19moles of Oxygen
Answer:
23.5 grams of AlBr3 will be produced by 27.20 grams of NaBr
Explanation:
The balanced equation here is
6NaBr + 1AlO3 = 3Na2O + 2AlBr3
6 moles of NaBr are required to produce 2 moles of AlBr3
Mass of one mole of NaBr = 102.894 g/mol
Mass of one mole of AlBr3 = 266.69 g/mol
Mass of 6 moles of NaBr = 6*102.894 g/mol
Mass of two moles of AlBr3 = 2*266.69 g/mol
6*102.894 g NaBr produces 2*266.69 g of AlBr3
23.5 grams of AlBr3 will be produced by (6*102.894)/(2*266.69 )*23.5 = 27.20 grams of NaBr
Earth is the only planet in the solar system with an atmosphere that
can sustain life. The blanket of gases not only contains the air that we
breathe but also protects us from the blasts of heat and radiation
emanating from the sun. It warms the planet by day and cools it at
night.
Earth's atmosphere is about 300 miles (480 kilometers) thick, but most
of it is within 10 miles (16 km) the surface. Air pressure decreases
with altitude. At sea level, air pressure is about 14.7 pounds per
square inch (1 kilogram per square centimeter). At 10,000 feet (3 km),
the air pressure is 10 pounds per square inch (0.7 kg per square cm).
There is also less oxygen to breathe.
If it were to be in a different position, life can no longer be alive on Earth.
