A very specific procedure scientists follow when conducting experiments is known as the
PtichkaEL [24]

Answer:

Scientific Method.

Explanation:

A scientific method is basically a method or a process when you conduct an experiment. Normally, the process goes like this:

1. You make like a question or something that you want to investigate, it's like the aim of the experiment.

2. You make an experiment and a hypothesis. A hypothesis is basically a guess on how the results of the experiment would turn out. You don't have to be correct for the hypothesis since there is no right or wrong answer.

3. Conduct the experiment. I don't think this needs a detailed explanation since experiments vary from one another.

4. Collect results. The data you collect come in different ways based on your experiment, but it is crucial you get data so that you can answer your question in 1.

5. Make inferences. You can't directly get a conclusion or answer from the results, so inferences are needed.

6. Craft a conclusion or answer. This is the final step when conducting an experiment and the part where you have the answer you needed when you conducted the experiment :)

If 25.0 g NO are produced, how many grams of nitrogen gas are used?
ivanzaharov [21]

Based on the assumption that the reaction involves N and O to produce NO, if 25.0 g of NO are produced, the amount of N gas used would be 11.66 grams

<h3>Stoichiometric calculation</h3>

From the equation of the reaction:

       N + O ---------> NO

Mole ratio of N to NO is 1:1

Mole of 25.0 g of NO = 25/30.01 = 0.833 moles

Equivalent mole of N = 0.833 moles

Mass of 0.833 moles N = 0.833 x 14 = 11.66 grams

A group of students are measuring how the acceleration of a mass will change when it is acted
Virty [35]

The scatter plot that shows a positive correlation between force and acceleration.

<h3>What is the relationship between acceleration of an object and the applied force?</h3>

The acceleration of an object is the change in velocity with time.

  • Acceleration = change in velocity/time

Force is defined as an agent which causes a change in the motion or state of rest of a body.

According to Newton's law of motion, the rate of change of velocity of an object is directly proportional to the applied force and takes place in the direction of the applied force.

Force and acceleration have a positive correlation.

Therefore, the scatter plot which will most closely match the measurements that the students will obtain is that which shows a positive correlation between force and acceleration.

In conclusion, acceleration of a object is proportional to the applied force.
