Answer:

Explanation:

The Key results in the Lab guide are results that justify the reasons to either accept or reject a hypothesis.

To summarize data related to findings in an experiments we make use of diagrams that shows the relationship between the different data.

Although the Lab guide in the question is missing a general answer within the scope of your question is provided above

Key results in an experiment are either milestone results leading to the final result of an experiment or results obtained that might not be part of the experiment but very important to the success of the experiments. therefore results that leads to the acceptance or rejection of a hypothesis in an experiment is a key result.   while

The best way to summarize data related to findings is the use of diagrams. ( graphical representation of the relationships between data contained in an experiment )

Hence we can conclude that use of diagrams is the best way to show the relationship between different data related to experimental findings while key results are results that justifies the acceptance of a hypothesis.

The rate of a chemical reaction is related to:_______
aalyn [17]

The correct answer for this question is activation energy, orientation, and frequency.

The rate of a chemical reaction is directly related to its activation energy because the higher the activation energy the lower is the rate of reaction as we know the reaction only proceed when the reactants have absorbed the enough heat energy to reach the transition state. Thus activation energy determines the rate of reaction.

The orientation of the particles is also very important as we know that the reaction between the two reactants only occur when they collide with proper orientation in time the greater the probability of the collision the greater is the rate of reaction and also the number of collisions also determines the rate of reaction.

The frequency is directly proportional to the rate of chemical reaction as the frequency of the collision increases the rate of the chemical reaction also increases.

ASAP<br>what is an electron cloud ​
Bad White [126]

Explanation:

An electron cloud is the region of space that surrounds the nucleus of an atom under the nucleus of the negatively charged sub-atomic particles.

  • An atoms is made up of some particles.
  • The proton is positively charged and it is located in the nucleus of an atom.
  • The neutrons do not carry any charges and occupies the nucleus with protons.
  • Electrons are the negatively charged particles outside the nucleus.
  • The electron cloud is portion of an atom with greatest probability of finding an electron.

The (triangle)Hrxn of formation of carbon dioxide is negative. Which statement is true? The reaction is endothermic. The reactio
ANEK [815]
The negative ion reactions that consist of the formation of carbon dioxide in the atmosphere is generally an exothermic reaction. By definition, an exothermic reaction takes place when the chemical process eventually releases heat as its by-product. It is in contrast in endothermic process wherein heat is absorbed.

A student has four resistors. Each resistor has a resistance of 100 ohms.
ValentinkaMS [17]

Answer:

The minimum resistance is 25 ohms.

Explanation:

Resistance of each resistor is 100 ohms. When resistors are connected in parallel, the equivalent resistance is lowest. For parallel combination, the equivalent resistance is given by :

\dfrac{1}{R}=\dfrac{1}{R_1}+\dfrac{1}{R_2}+....

Here, all resistors are 100 ohms. So,

\dfrac{1}{R}=\dfrac{1}{100}+\dfrac{1}{100}+\dfrac{1}{100}+\dfrac{1}{100}\\\\R=25\ \Omega

So, the minimum resistance is 25 ohms.
