Answer:

Solid phase has a fixed shape and volume

Explanation:

A solid has a definite volume and a definite shape.

A liquid a definite volume and no definite shape.

A gas no definite volume and no definite shape.

Solids

1. Solids have a definite volume and definite shape

2. The particles present in a solid are very closely packed since the intermolecular forces between them are very strong. The molecules do not move apart.

Liquids

1. Liquids have a definite volume and no definite shape

2. The particles present in a liquid are closely packed since the intermolecular forces holds the molecules close together. The molecules slide over each other.

3. Liquids take up the shape of the container

Gases

1. Gases have no definite volume and no definite shape

2. The particles present in a gas are very loosely packed since the intermolecular forces are very weak.

3. There are no attractive forces between the molecules.

4. Gases spread through the container

1. What is the relationship between ecological succession and equlibrium in an ecosystem?

alexandr1967 [171]

Answer:

Equilibrium in ecology refers to a state that occurs such that a small disturbance or change is counter balanced by another change so that the community is restored to its original state. Thus, as a community goes through multiple changes through each stage of succession, it is not in equilibrium.

Combustion of hydrocarbons such as butane () produces carbon dioxide, a "greenhouse gas." Greenhouse gases in the Earth's atmosp

Dahasolnce [82]

Answer:

1. C₄H₁₀ + ¹³/₂O₂ → 4CO₂ + 5H₂O

2. V = 596L

Explanation:

Butane (C₄H₁₀) reacts with oxygen (O₂) to produce carbon dioxide (CO₂) and water (H₂O) thus:

C₄H₁₀ + O₂ → CO₂ + H₂O

1. The balanced chemical equation is:

C₄H₁₀ + ¹³/₂O₂ → 4CO₂ + 5H₂O

2. 0,360kg of butane are:

360g× $\frac{1mol}{58,12g}$ =6,19moles of butane

These moles of butane are:

6,19moles of butane× $\frac{4CO_2}{1molButane}$ = 24,8 moles CO₂

Using V=nRT/P

Where:

n are moles (24,8 moles CO₂); R is gas constant (0,082atmL/molK); T is temperature, 20°C (293,15K); and P is pressure (1atm).

Volume (V) is:

V = 596L

What happens when an electron in its lowest energy level or ground state when it is by absorbs energy?

tester [92]

Explanation:

atom changes from a ground state to an excited state by taking on energy from its surroundings in a process called absorption. The electron absorbs the energy and jumps to a higher energy level. In the reverse process, emission, the electron returns to the ground state by releasing the extra energy it absorbed
