Answer:

+2.5

Explanation:

So the oxidation number of S in Na2S4O6is +2.5.

Answer:

Explanation:

Oxidation number of Na = 1+   There are two of them, so it is 2*1 = 2

Oxidation number of O =  2-    There are 6 of them so 6 * 2-    =  -12

There are 4 S's so the oxidation number is 4*S

Now set up a small equation

2 + 4s - 12 = 0

And solve.

2 - 12 + 4s =0

-10 + 4s =   0

4s = 10

4s/4 =10/4

s = 2.5

Two basic properties of the gas phase are
Molodets [167]
The choices can be found elsewhere and as follows:

A.) a definite shape and a definite volume
B.) a definite shape but no definite volume
C.) no definite shape and no definite volume

I believe the correct answer is option C. Two basic properties of the gas phase would be it has no definite shape and no definite volume. It takes the shape and volume of its container. Hope this answers the question.

A researcher is measuring changes in the density of the upper atmosphere over time. Which units should be used for the density m
valina [46]

Answer:

lbm/ft³ or psi/ft

Explanation:

The description in the question shows the density to measured is that of gases (upper atmosphere). The density of a gas can be described as the mass of the gas divided by the volume of the gas at a certain temperature and pressure. It's unit can be represented as lbm/ft³ or psi/ft.

NOTE:

"lbm" means "lean body mass" which is a unit for mass or weight and can be described as the pound mass

"psi" means "pound per square inch"; is also a unit for mass or weight

When a sample of a gas is heated in a sealed, rigid container from 200. K to 400. K, the pressure exerted by the gas is:
gavmur [86]
When a sample of a gas is heated in a sealed, rigid container from 200 degree Kelvin to 400 degree Kelvin, the pressure exerted by the gas is increased by a factor 2. Heating any gas actually increases the volume of the gas within a container. As the temperature of the gas rises, the molecules of the gas start moving faster and start striking the walls of the container in which it is kept with more force. The volume of the container tries to expand to accommodate the fast colliding molecules of the gas.
