Evaluate the carbon dioxide molecule. Explain how to determine if double or triple bonds exist in the molecule. Use details to support your
answer
Answer:
Double Bonds
Explanation:
CO2 has two double bonds going from carbon to the oxygen atoms. Each oxygen atom needs to bond twice and the carbon atom needs to bond four times. Carbon has four valence electrons, and oxygen has six. Carbon shares two of its valence electrons with each of the two oxygen atoms, forming two double bonds.

identify whether each change represents an oxidation or reduction. then determine how many electrons were involved and which side of the reaction they should appear on in the half-reaction.
In a redox reaction, we can identify 2 kinds of half-reactions:
Oxidation: the oxidation number increases.Reduction: the oxidation number decreases.Let's consider the following half-reactions.
Al ⇒ Al³⁺This is an oxidation because the oxidation number increases from 0 to 3+. To balance it, we need 3 electrons on the right side.
Cu²⁺ ⇒ CuThis is a reduction because the oxidation number decreases from 2+ to 0. To balance it, we need 2 electrons on the right side.
2 F⁻ ⇒ F₂This is an oxidation because the oxidation number increases from -1 to 0. To balance it, we need 2 electrons on the right side.
Al ⇒ Al³⁺ is an oxidation and 3 electrons on the right side are needed.Cu²⁺ ⇒ Cu is a reduction and 2 electrons on the left side are needed.2 F⁻ ⇒ F₂ is an oxidation and 2 electrons on the right side are needed.Learn more: https://brainly.com/question/2671074

a.
The mass of the products is always twice the mass of the reactants.
b.
The mass of the products stays the same during a chemical reaction
c.
The mass of the reactants stays the same during a chemical reaction
d.

1. What two factors change the speed of the atoms/molecules?
Answer:
With an increase in temperature, the particles gain kinetic energy and move faster. The actual average speed of the particles depends on their mass as well as the temperature – heavier particles move more slowly than lighter ones at the same temperature.

How should an amoeba be classified
Explanation:
Amoebas are identified by their ability to form temporary cytoplasmic extensions called pseudopodia, or false feet, by means of which they move about. This type of movement, called amoeboid movement, is considered to be the most primitive form of animal locomotion.
Determine the amount of heat energy in joules required to raise the temperature of 7.40g of water from 29.0OC to 46.0 OC Specific heat of water is: 4.184 J/gOC
The amount of heat energy in joules required to raise the temperature of 7.40g of water is 526.35 Joules
The amount of energy is expressed according to the formula expressed as:
[tex]E = mc\triangle \theta[/tex]
m is the mass of water = 7.40grams
c is the specific heat of water = 4.184 J/g⁰C
[tex]\triangle \theta = 46 - 29\\ \triangle \theta = 17^0[/tex]
Substitute the given parameters into the formula:
[tex]E = 7.4 \times 17 \times 4.184\\E=526.3472Joules[/tex]
Hence the amount of heat energy in joules required to raise the temperature of 7.40g of water is 526.35 Joules

Porphyry copper deposits that are weathered are more valuable than nonweathered deposits because ______.
Porphyry copper deposits describes copper ore bodies which are formed from large copper ore bodies due to the high temperature exerted by magmatic fluid originating below the ore deposit.
Weathered portion of the Porphyry copper resulting from the reaction of hydrothermal fluid are washed to greater depth level below the unweathered portion of the deposit. Copper deposits at greater depth are usually more concentrated with copper than those above.Hence, reason why weathered porphyry are more valuable than unweathered porphyry.

Determine the heat required to raise the temperature of 9.4 mole of water from 75.0oC to 125oC at atmospheric pressure. Note that water transitions from the liquid to the vapor state. Express your answers in Joules.
The heat capacity required to raise the temperature of 9.4 mole of water from 75.0oC to 125oC at atmospheric pressure is 35429 J.
The following information is available from the question;
Number of moles = 9.4 mole
Initial temperature = 75.0oC
Final temperature = 125oC
Molar heat capacity = 75.38 J/mol °C
Now;
H = ncθ
m = Number of moles of water
c = Molar heat capacity of water
θ = Temperature rise
Substituting values;
H = 9.4 mole × 75.38 J/mol °C × ( 125oC - 75.0oC)
H = 35429 J
