Ricky and Shemane, who are stoked to be learning stoich, were working diligently on a chemistry assignment in class. Ricky reali

zed that in most chemical reactions, there’s an excess of one reactant. How would Shemane correctly explain to Ricky why this occurs?
the reaction will continue until all of the limiting reactant is consumed.

reactions do not take place unless there are unequal amounts of reactants.


the reaction will continue until all of the excess reactant is consumed.


reactions occur too quickly if equal amounts of reactants are used.

Information about how a chemical reacts under high pressure can be found in the ""reactivity"" section of a msds. True or false?
dezoksy [38]

Information about how a chemical reacts under high pressure can be found in the "reactivity" section of a MSDS: True.

<h3>What is MSDS?</h3>

MSDS is an abbreviation for Material Safety Data Sheet and it can be defined as a text-based document which is designed and developed to provide more information with respect to the chemical and physical properties of an equipment, chemical compound, or substance, based on the following:

  • Reactivity
  • Flammability
  • Temperature
  • Radioactivity

In this context, we can infer and logically deduce that it is true that the information about how a chemical react would under high pressure can be found in the "reactivity" section of a Material Safety Data Sheet (MSDS).

Imagine that you could increase the gravitational
Monica [59]

Answer:

You weight would be doubled because gravitational force is doubled

2. Challenges:

a. Everyone’s body would have to adjust to the new weight and learn to walk again

b. Earth would be closer to the sun, so everything would be hotter on Earth

c. Flying airplanes and driving cars might no longer work at all (talk about how difficult this would make traveling)

3. Benefits:

a. Time would go by much slower so technically everyone would live longer

b. Balloons wouldn’t fly off anymore

Answer 3 &amp; 4
Anastasy [175]

Answer:

The answer  for 2-hexene is that the structure should have 6 carbon with a double bond beginning on the 2nd carbon atom.

The answer for 1-pentyne is that the structure should have 5 carbon with triple bond beginning on the 1st carbon atom.

Explanation:

<u>2-Hexene</u>

The structural formula for 2-hexene will have 6 carbons because the nomenclature has a -hex prefix, which stands for 6 carbons.

The -ene suffix of the nomenclature means that the organic compound is an alkene. Alkenes are hydrocarbons that contain double covalent bond and  have the suffix -ene.

The double bond is on the 2 carbon atom because the nomenclature states that the double bond will be on the 2 carbon atom.

<u>1-Pentyne</u>

The structure will have 5 carbons since the -pent prefix means 5 carbons.

The structure has a triple bond because the -yne suffix means that the structure is an alkyne. An alkyne is a hydrocarbon with triple covalent bonds.

Also, the position of the triple bond is known because the nomenclature of the alkyne states that the triple bond is on the 1st carbon.

All of the cells in the body need oxygen. Hemoglobin molecules in red blood cells transport oxygen through the bloodstream. Oxyg
tankabanditka [31]

Answer:

High partial pressure of oxygen in the tissues.

Explanation:

Hemoglobin is a protein found in the red blood cells that is responsible for the transportation of oxygen from the lungs to the rest of the tissues in the body. The partial pressure determines whether oxygen is loaded or unloaded into the hemoglobin.

When there is lack of oxygen in our bodies, we experience hypoxia.
