Well, I'm not completely sure, but, I'm going to try and help you: First, you would need to observe the machine, which, would represent the first step. Secondly, you would have to ask yourself a question, when the ball shoots out, which way are you going to hit it? Next, you'd have to hypothesize, which way the ball will come, which way will give you the most points. etc, etc. Then, you'd make a prediction based on your hypothesis, predict the direction that will give you the most points, and which way the ball will fall. Now, when the ball shoots out, you'd gave to test your prediction, then you'd see if your hypothesis was correct. Lastly, you would iterate, and, come up with new hypotheses, and, predictions, for when you play on round two, this would, also, help you get better at the game, just as, when you perform other scientific experiments, you would have a better idea on what would happen during them. I hope this helps!!!

Draw the structures of two stereoisomeric alkenes that would give 3-hexanol as the only major product of hydroboration followed
soldi70 [24.7K]

Answer:

cis-3-hexene and trans-3-hexene

Explanation:

Hydroboration oxidation is a method of preparation of alcohol from alkene.

Hydroboration follows anti-Markovnikoff rule in which alcohol group attached to less substituted carbon. Stereochemistry of the product is always syn that is H and OH attached to the same side of the double bond.

cis-3-hexene and trans-3-hexene undergoes hydroboration to form 3-hexanol.

Is a 1.4% NaCl solution hypertonic, isotonic, or hypertonic
dusya [7]

Answer:

1.4% NaCl solution is Hypertonic

Explanation:

A hypertonic solution is type of solution that has a greater concentration of solutes (substance given in a solution) on the outside of a cell when compared with the inside of a cell.

Any solution of sodium chloride (NaCl) in water with a concentration of NaCl higher than that found in physiological saline (0.9%) is considered to be hypertonic

3.Write the symbol of the element that has a charge of +1 when it has 71 electrons.​
tigry1 [53]

The symbol : \tt _{72}^{178}Hf^{+1}

<h3>Further explanation </h3>

There are two components that accompany an element, the mass number and atomic number

Atoms are composed of 3 types of basic particles (subatomic particles): <em>protons, electrons, and neutrons </em>

The Atomic Number (Z) indicates the number of protons and electrons in an atom of an element.

Atomic number = number of protons = number of electrons ⇒ neutral number

Atomic mass is the sum of protons and neutrons

Atomic Number (Z) = Atomic mass (A) - Number of Neutrons

The element has 71 electrons and a charge of +1 , so

Number of protons = 71 + 1 = 72

Number of protons = the atomic number = 72

The element with atomic number 72 is Hafnium(Hf)

The atomic mass of Hf = 178 g/mol
