Answer:
In chemistry, the ball-and-stick model is a molecular model of a chemical substance which is to display both the three-dimensional position of the atoms and the bonds between them. The atoms are typically represented by spheres, connected by rods which ... Double and triple bonds are usually represented by two or three curved rods, ...

<em>Calculate the energy required to heat 179g of ethanol from -2.2 °C to 19.6 °C. Assume the specific heat capacity of ethanol under these conditions is 2.44 J/g.°C. Be sure your answer has the correct number of significant digits.</em>
Step 1: Given data
- Mass of ethanol (m): 179 g
- Initial temperature: -2.2°C
- Final temperature: 19.6 °C
- Specific heat capacity of ethanol (c): 2.44 J/g.°C
Step 2: Calculate the temperature change
ΔT = 19.6 °C - (-2.2 °C) = 21.8 °C
Step 3: Calculate the energy required (Q)
We will use the following expression.
Q = c × m × ΔT
Q = 2.44 J/g.°C × 179 g × 21.8 °C
Q = 9.52 × 10³ J
Yes gas particles are infinitely small
These responses are called "Reflex Action"
Hope this helps!
To create an electron dot diagram first identify the element the diagram is about and then use dots around the symbol of the element to represent the electrons.
Each atom includes three main sub-particles: protons, neutrons, and electrons. In regular atoms, the number of protons is equal to the number of electrons.
Moreover, it is common to represent the number of electrons using Lewis structure also known as dot diagram. To create a dot diagram follow these steps:
- Find the symbol of the element and write it in the center. For example carbon = C or mercury = Hg
- Determine the number of valence electrons or the electrons in the outer shell. For example, Chlorine has 7 valence electrons.
- Represent the electrons with dots around the symbol. To do this, remember the dots are placed up, down, and to the sides of the symbol and you should draw only one electron at a time.
Note: This question is incomplete because the elements for the diagram are not provided; due to this, I answered this question based on general knowledge.
