Answer:
The major ionic constituents whose concentrations can be determined from the salinity are known as conservative substances. Their constant relative concentrations are due to the large amounts of these species in the oceans in comparison t
Answer:
Number of Significant Figures: 5
The Significant Figures are 1 1 0 0 5
Explanation:
87.75 g of fructose
Explanation:
molar concentration = number of moles / volume (L)
number of moles = molar concentration × volume
number of moles of fructose = 1.5 × 0.325
number of moles of fructose = 0.4875 moles
number of moles = mass / molar weight
mass = number of moles × molar weight
mass of fructose = 0.4875 × 180
mass of fructose = 87.75 g

Answer:
The new volume is 5.92 L, which is approximately 6 L
Explanation:
As the gas temperature increases, the molecules move faster and take less time to reach the walls of the container. This means that the number of crashes per unit of time will be greater. That is, there will be an increase (for an instant) in the pressure inside the container and the volume will increase.
So Charles's Law is one of the gas laws that relates the volume and temperature of a certain amount of gas at constant pressure and says that:
- If the temperature increases the volume increases
- If the temperature decreases the volume decreases
Mathematically this is expressed by:

When you want to study two different states, an initial and a final one of a gas, this law is expressed by:

In this case:
- V1: 8 L
- T1: 473 K
- V2: ?
- T2: 350 K
Replacing:

Solving:

V2=5.92 L
<u><em>The new volume is 5.92 L, which is approximately 6 L</em></u>
Answer:
Fluorine = 7 v.e.
Sulfur = 6 v.e.
Oxygen = 6 v.e.
Nitrogen = 5 v.e.
Carbon = 4 v.e.
Explanation:
Valence electrons can be easily determined by understanding groups (columns). Every element in. . .
column 3A (13) = 3 v.e.
column 4A (14) = 4 v.e.
column 5A (15) = 5 v.e.
column 6A (16) = 6 v.e.
column 7A (17) = 7 v.e.
