Answer:

300 K

General Formulas and Concepts:

Atomic Structure

Diatomic Elements
Moles

Gas Laws

Ideal Gas Law: PV = nRT

P is pressure
V is volume
n is moles
R is gas constant
T is temperature

Explanation:

Step 1: Define

Identify variables

[Given] n = 0.5 mol N₂

[Given] V = 6 L

[Given] P = 2 atm

[Given] R = 0.0821 L · atm · mol⁻¹ · K⁻¹

[Solve] T

Step 2: Solve for T

Substitute in variables [Ideal Gas Law]: (2 atm)(6 L) = (0.5 mol)(0.0821 L · atm · mol⁻¹ · K⁻¹)T
Multiply [Cancel out units]: 12 atm · L = (0.04105 L · atm · K⁻¹)T
Isolate T [Cancel out units]: 292.326 K = T
Rewrite: T = 292.326 K

Step 3: Check

Follow sig fig rules and round. We are given 1 sig fig as our lowest.

292.326 K ≈ 300 K

Explain how physical and chemical properties influence the formation of ocean current and the distribution of marine life.

tia_tia [17]

<h2>Answer:</h2>

The physical and chemical properties of seawater vary according to latitude, depth, nearness to land, and input of fresh water. The physical and chemical properties of seawater have a great effect on organisms, varying especially with the size of the creature. Marine organisms have evolved a wide variety of unique physiological and morphological features that allow them to live in the sea.

Match the scientist with their scientific idea. Question 2 options: Substances combine or break apart to create new, different s

aev [14]

Answer:

1. Democritus - Matter was made of different kinds of things.

2. Bernoulli- Gases are formed from tiny particles so small you can’t see them. The particles are spread out into a certain area and move when people walk through them.

3. Priestley- Substances combine or break apart to create new, different substances.

Explanation:

1. Democritus was a philosopher who because of his immense contribution to atomic theory was regarded as the "FATHER OF SCIENCE". His idea was that matter was made of different kinds of things called which he called ATOMOS meaning ATOM.

2. Daniel Bernoulli was another outstanding mathematician and scientist who played a major part in the kinetic molecular theory of gases via his "HYDRODYNAMICA". His idea, which states that "gases are formed from tiny particles so small you can’t see them. The particles are spread out into a certain area and move when people walk through them"

was based on fluid dynamics.

3. Joseph Priestley is remarkably known for his 1774 discovery of oxygen. His findings that air is a mixture of gases and not just a substance made of one element paved the way for his idea that " Substances combine or break apart to create new, different substances".
