Spongebob completed his experiment. He wrote a brief summary about the investigation. He also determined that his hypothesis statement was not right and explained why it wasn't right by providing evidence from the investigation. Spongebob utilized which step of the scientific method?
Answer:
In a 7-step scientific method, Spongebob utilized the 6th step when He wrote a brief summary of the investigation, and Spongebob utilized the 7th step when He also determined that his hypothesis statement was not right and explained why it wasn't right by providing evidence from the investigation.
Explanation:
Scientific Methods are organized ways employed by scientists to tackle problems by providing solutions to the problem or make hypotheses to which other scientists build on to provide solutions to the problem.
The steps of the scientific method are:
Step 1- Understand the Problem
Step 2- Make research
Step 3- Hypothesis.
Step 4- Conduct an experiment to test the hypothesis
Step 5- Observations.
Step 6-Results/Conclusion.
Step 7- Communicate your research

The number of electrons in the first three energy levels for four neutral elements is shown in the table. The element with the highest ionization energy is-
Answer:
The correct option is;
Element 2
Explanation:
The ionization energy is the energy required to eject an electron from a gaseous ion or atom
The ionization energy increases across the period and increases up the group
The elements with the highest ionization energy are those that have the complete octet structure in their outermost shell, which are the noble gases
Therefore, given that element 2, which has the complete octet structure in the outermost shell, then it is an element of the noble gases which have the highest ionization energy in a period, and therefore has the highest ionization energy.
On the periodic table, the element with 10 electrons is Neon, with ionization energy of 2080.68 kJ/mol which is the second highest after helium, that has only 2 electrons.

Explanation:
A student mixed several different 12 mm plastic beads together by mistake. Luckily the beads had different densities. One group of beads had a density of 0.6 g/cm3; the other beads had a density of 1.2 g/ cm3. Describe a method the student can use to sort the beads.
Answer:
The answer is "Each student will get a glass of water and drop the bead into it but the beads float 0.6 g / cm3 and slip down to 1.2 g / cm3
".
Explanation:
One's masses would've been dissimilar, even though their width and concentrations were also equal. Whenever the type-A mass is m, then the type-B mass is 2 m. One should measure then, therefore.
Water has a 1g / cm^3 density. Although Type A is higher than air, Type B is much more compact. it means will float if they place it in water type-A where type-B sinks.

Explain the difference between potential energy and kinetic energy.
Sentence Starters
"Potential Energy is. . "
"Kinetic Energy is. . "
"The difference between potential energy and kinetic energy is. . ."
Answer:
Potential energy is the stored energy in an object or thing, while kinetic energy is the energy which an object contains because of a particular motion.
Explanation:
Potential energy is energy that is stored for example a wind up toy, it has energy but in order for you to get kinetic energy, it has to move. So kinetic energy is moving energy.
The difference is that potential is stored and kinetic is moving energy.

You are an employee at "cash for gold" and a customer comes in looking to exchange gold for money. They claim to have 3.47 gram nugget of fold. How many particles (atoms) of gold are in one nugget? With work shown
Answer:
The number of atoms in 3.47 gram nugget of gold is approximately 1.0606 × 10²² atoms
Explanation:
The given mass of gold = 3.47 grams
The molar mass of gold = 196.96657 g/mol
The number of moles of gold in 3.47 grams of gold = 3.47 grams/(196.96657 g/mol)
The number of moles of gold in 3.47 gram nugget of gold = 0.01762 moles
The number of atoms in one mole of gold = 6.02 × 10²³ atoms
The number of atoms in 0.01762 moles of gold = 6.02 × 10²³ atoms/mole × 0.01762 moles
The number of atoms in 0.01762 moles of gold ≈ 1.0606 × 10²² atoms
∴ The number of atoms in 3.47 gram nugget of gold ≈ 1.0606 × 10²² atoms.

Identify and give an example of at least two molecular properties that could be used to separate a substance from a mixture.
Answer:
Two molecular properties that could be used to separate a substance from a mixture are - Filtration and Chromatography .
Explanation
Molecular property -Molecular properties include the chemical properties, physical properties, and structural properties of molecules, including medicines. Typically, molecular properties do not include a chemical compound's pharmacological or biological properties.
Filtration -: Using a filter medium that allows the fluid to move through but not the solid, filtration is a method used to distinguish solids from liquids or gases. The term 'filtration' refers whether the filter is mechanical, chemical, or physical. The filtrate is considered the fluid that flows through the filter. A surface filter, which is a solid that traps solid particles, or a depth filter, which is a bed of material that traps the solid, may be the filter medium.Usually, filtration is an imperfect operation. On the feed side of the filter or embedded in the filter media, some fluid remains and some tiny solid particles make their way through the filter.
example - Filters containing fibers that trap particulates are used by many aquariums.
Chromatography -: A laboratory method for the isolation of a mixture is chromatography. The mixture is dissolved in a fluid called the mobile phase (gas, solvent, water) that carries it through a device (a column, a capillary tube, a plate, or a sheet) on which a material called the stationary phase is fixed. For the stationary step, the different constituents of the mixture have different affinities.Chromatography can be analytical or preparatory. Preparative chromatography is intended to isolate the components of a mixture for subsequent use and is therefore a method of purification. Analytical chromatography is usually conducted with smaller quantities of material and is intended to assess the presence of analytes in a mixture or to measure their relative proportions. Both are not limited to each other.
An example of chromatography is when a chemical reaction is used to separate each of the various sized molecules on a piece of paper in a liquid compound into their own pieces.
Hence , the answer is filtration and chromatography .
