Why are units used that are to express the densities of gases different from those used to express the densities of solids or liquids

Answers

Answer 1

Answer: If the units for gases were the same as the units for numbers would be too small to be convenient.

For example, the density of iron is 7.87 g/cm³.

Using the same units, the density of hydrogen is 0.000 0899 g/cm³.

It is much more convenient to express the density in numbers that are easier to visualize: 0.0899 g/L, and that is still a small number.

A gas occupying a volume of 381 mL at a pressure of 5 mmHg is allowed to expand until the pressure reaches 589 mmHg. What is the final volume in mL?

Answers

The final volume of the gas is approximately 3.24 mL when the pressure has increased from 5 mmHg to 589 mmHg.

To solve this problem, we can use the combined gas law, which relates the pressure, volume, and temperature of a gas. The formula for the combined gas law is:
P1V1/T1 = P2V2/T2
where P1, V1, and T1 are the initial pressure, volume, and temperature of the gas, and P2, V2, and T2 are the final pressure, volume, and temperature of the gas.
In this problem, we are given the initial volume (V1 = 381 mL) and pressure (P1 = 5 mmHg), and we want to find the final volume (V2) when the pressure has increased to 589 mmHg. We can assume that the temperature remains constant.
We can start by rearranging the combined gas law to solve for V2:
V2 = (P1V1/T1) x (T2/P2)
Since the temperature is constant, we can simplify the formula to:
V2 = (P1V1)/P2
Plugging in the values we know, we get:
V2 = (5 mmHg x 381 mL)/589 mmHg
Simplifying, we get:
V2 = 3.24 mL

Coastal flooding occurs when_

A. Rocks or debris block rivers causing them to overflow

B. Severe weather occurs causing large waves to hit the coast

C. Huge amounts of snow and ice melt due to sudden temperature variations

D. Colossal amounts of rain fall in a short period of time

Answers

Coastal flooding occurs when normally dry, low-lying land is flooded by seawater.[1] The extent of coastal flooding is a function of the elevation inland flood waters penetrate which is controlled by the topography of the coastal land exposed to flooding.The seawater can flood the land via from several different paths:

Based on its location in the periodic table, what can most likely be predicted about phosphorus?It has three valence electrons available for bonding.
It has three nonbonding electrons.
It has five valence electrons available for bonding.
It has five nonbonding electrons.

Answers

It has 5 valence electrons available for bonding. The noble gas configuration of phosphorus is [Ne]3s²3p³ showing that phosphorus has 5 valence electrons (2 in the s orbital and 3 in the p orbital).
I hope this helps. Let me know in the comments if anything is unclear.

Answer:The answer is "It has five valence electrons available for bonding". An element's group number is equivalent to the number of valence electrons that it has. This means that since phosphorus is found on group number 5, it has 5 valence electrons that participate in bonding. It also means that it needs 3 more electrons to complete its valency.
