Zigmanuir [339]
Since there are no choices given, my answer might not be what you're looking for. But it can definitely be a correct answer. The technique is called filtration. Filtration is a physical separation to separate the liquid and solid in a mixture. The mixture should be composed of an insoluble solid in a solvent. The mixture is usually passed through a semi-permeable barrier. In this case, a special piece of paper is used. The solvent is the liquid and the solid is the coffee bean grounds. Only the liquid can pass through the paper. The liquid that passes through the paper is generally called a filtrate.

Ap chemistry how to determine if compound is ionic or molecular bqsed on formula
ludmilkaskok [199]
Ionic compound consists of a positively charged ion and a negatively charged anion. For example, NaCl. Na (sodium) is a cation (another word for positively charged ion) and Cl (chloride) is a anion (another way for negatively charged ion.)

Molecular compounds consists of only negatively charged ions. For example Br2I is a compound of 2 elements that are negatively charged.

Unlike ionic compounds, molecular compounds consists of two or more negatively charged elements.

In a neutral atom, the number of protons is always equal to what other part of the atom?
Licemer1 [7]

Answer:

b. The number of electrons

Explanation:

A "neutral atom" has a <u>neutral charge</u>. This means that <em>its charge is equal to </em><em>zero. </em>In order for the charges to cancel out each other, the atom's <em>positive charge should be equal to the negative charge. </em>These being said, the number of electrons<em> (negatively-charged)</em> is then equal to the number of protons <em>(positively-charged). </em>Those atoms which are not neutral are called <em>"ions."</em> This means that they either have more or less electrons than the protons.

Describe how you would set up an experiment to test the rela-tionship between completion of assigned homework and the fi-nal gra
ValentinkaMS [17]

To start this test, you need to identify the variables it presents. As you may already know, there are independent and dependent variables. Independent variables are those that act on a factor, influencing it to generate a result. In the case of this experiment, the independent variable is the completion of the homework. The dependent variable, in turn, is the factor that receives the influence of the independent variable, in this experiment this variable is the final grade you received in the course.

After that you must select a number of students, give them their homework and ask each student to complete a percentage of that amount. An example of this could be that you select 11 students and ask the first to complete 0% of the homework, the second student must complete 10%, the third 20% and so on, and the 11th student must complete 100% of the homework.

after that, note what was the final grade that each student received in the course and make a graph to show the results.

The y-axis of the graph must represent the dependent variable, while the x-axis must represent the independent variable. This way you will show the exact relationship between completing homework and the final grade of the course.
