We can conclude that each carbon atom in acetylene shares one pair of electrons with the hydrogen atom and three pairs with the other carbon atom.

A chemical bond is a long-lasting attraction between atoms or ions that allows molecules and crystals to form. Ionic bonds are formed by the electrostatic force between oppositely charged ions, whereas covalent bonds are formed by the sharing of electrons.

Each carbon atom in acetylene shares one pair of electrons with the hydrogen atom and three pairs with the other carbon atom.

The carbon atom contains four electrons. It requires four electrons to become stable in its outermost shell. Two carbon atoms covalently bond three pairs of electrons with each other in acetylene, and the remaining pair covalently bonds with two hydrogen atoms.

As a result of the carbon and hydrogen atoms becoming more stable, we can conclude that in acetylene, each carbon atom shares one pair of electrons with the hydrogen atom and three pairs with the other carbon atom.

Answer:

1. Dissolving powder in milk - Chemical

  - It is chemical because the milk has changed on a molecular level

2. Toasting bread - Chemical

   - It is chemical because adding heat to the bread cooks it, therefore

     changing it on a molecular level

3. Melting cheese - Physical

   - It is physical because the physical appearance was the only change

4. Slicing apples or bannanas - Physical

   - It is physical because the physical appearance was the only change

5. Frying an egg - Chemical

   - It is chemical because new particles were formed

6. Milk souring - Chemical

   -  It is chemical because it is forming a new product (lactic acid)

Explanation:

Physical Change occurs when the particles of a substance become rearranged, but do not change into different particles.  

Chemical change occurs when a new substance is formed. This process is irreversable.

2C6H10 + 17O2 = 12CO2 + 10H2O
Ad libitum [116K]

Answer:

n O2 = 2.125 mol

Explanation:

balanced reaction:

  • 2C6H10 + 17O2 → 12CO2 + 10H2O

∴ n CO2 = 1.5 mol

⇒ n O2 = (1.5 mol CO2)*(17 mol O2/12 mol CO2)

⇒ n O2 = 2.125 mol

The complete combustion of propane (C3H8) in the presence of oxygen yields CO2 and H2O: C3H8 (g) + 5O2 (g) 3CO2 (g) + 4H2O (g) a
mixas84 [53]

Answer:

26.9 L is the volume of CO₂, we obtained

Explanation:

The reaction is: C₃H₈(g) + 5O₂(g)  →  3CO₂ (g) + 4H₂O (g)

Let's determine the reactants moles:

27.5 g . 1mol / 44 g = 0.625 moles

We need density of O₂ to determine mass and then, the moles.

O₂ density = O₂ mass / O₂ volume

O₂ density . O₂ volume = O₂ mass

1.429 g/L . 45L = O₂ mass → 64.3 g

Moles of O₂ → 64.3 g . 1mol/32g = 2.009 moles

Let's find out the limiting reactant:

1 mol of propane needs 5 moles of oxygen to react

Then, 0.625 moles will react with (0.625 . 5)/1 = 3.125 moles of O₂

Oxygen is the limiting reactant, we need 3.125 moles but we only have 2.009 moles

Ratio is 5:3. 5 moles of O₂ produce 3 moles of CO₂

Therefore, 2.009 moles of O₂ must produce (2.009 .3) /5 = 1.21 moles of CO₂. Let's find out the volume, by Ideal Gases Law (STP are 1 atm and 273K, the standard conditions)

1 atm . V = 1.21 moles . 0.082 . 273K

V = (1.21 moles . 0.082 . 273K) / 1atm = 26.9 L

How does Earth's rotation affect ocean currents?
Tom [10]

Answer:

Our planet's rotation produces a force on all bodies moving relative to theEarth. ... The force, called the "Coriolis effect," causes the direction of winds and ocean currents to be deflected.

PLEASE HELP, EASY QUESTION!!!!  Which of the following best describes the freezing of water?
VLD [36.1K]
I think the correct answer would be negative change in enthalpy, low temperature and negative entropy. Freezing of water is an exothermic process which means heat is released to the surroundings so negative enthalpy. And this is seen in the change to a lower temperature. Entropy is negative which signifies that there is more order as water freezes.
