How do you identify the solute and solvent of SO^2
Answer:
How to identify a solute and solvent?
It is not possible to identify the solute and solvent as different substances in a solution. In a solution of table salt and water, the salt is the solute and the water is the solvent. In the cells of your body, substances such as calcium ions and sugar are solutes, and water is the solvent.

Since sodium chloride is classified as a compound, a sample of it contains A. atoms that are gases, liquids, and solids. B. matter that cannot be reduced to atoms. C.more than one kind of atom. a solution of atoms and molecules.
Answer:
more than one kind of atom. a solution of atoms and molecules.
Explanation:
Although the formula for sodium chloride is NaCl, the compound does not contain actual NaCl molecules. Rather, it contains equal numbers of sodium ions with a charge of positive one (Na+) and chloride ions with a charge of negative one (Cl−).
Since sodium chloride is classified as a compound, a sample of it contains more than one kind of atom, a solution of atoms and molecules.
Compounds are generally made up of atoms of different elements. The elements could be two or even more than two.
Compounds are as opposed to elements because the latter contains atoms of the same substance.
Molecules are the smallest unit of a compound that can take part in reactions.

An atom's nucleus contains three protons and three neutrons. What is the
overall charge of the nucleus?
A. -3
B. +6
C. +3
D.O
Answer:
C- +3
Explanation:
Protons equal one positive charge, neutrons equal one neutral charge.
3 + 0 = 3
An atom's nucleus contains three protons and three neutrons. Then the overall charge of the nucleus is +3. Therefore, option C is correct.
What is neutron ?The neutron, symbol n or n0, is a subatomic particle with a neutral charge and slightly more mass than a proton. Atomic nuclei consist of protons and neutrons.
When alpha particles strike any of a number of light isotopes, such as isotopes of beryllium, carbon, or oxygen, neutrons are created. This means that an alpha-emitter, such as radium, polonium, or americium, can be combined with a low-atomic-weight isotope to create a neutron source.
The neutrons' main job in an atom's nucleus is to contribute to the nuclear glue, or binding energy, that binds the nucleus together. This is understandable as follows: Protons and neutrons make up an atomic nucleus.
Thus, option C is correct.

Which statement about the electron-cloud model is true? It is the currently accepted atomic model. It can easily be replaced by existing models. It specifies the location and momentum of an electron. It does not explain the formation of emission lines.
Answer:
A
Explanation:
just did the test
The electron cloud model is the modern model of the atom that contrasts the exact position of the electron. It is the currently accepted atomic model. Thus, option A is correct.
What is the electron-cloud model?The electron-cloud model is currently accepted and used model that states about the moving electron cloud around the nucleus in an atom. It contrasts with the previous models.
The electron cloud gives the probable position of the electron rather than a fixed position. It was given by Erwin Schrodinger that showed electrons no longer move in a fixed orbital around the atom.
The position of the electron is determined based on the cloud where they are most likely to be present. The field with high probability is represented as a dense area.
Therefore, option A. electron-cloud model is a modern atomic model.

Answer:

The student performed an experiment to test his hypothesis about sunlight and plant height using two plants. He kept everything the same between two tomato plants except he exposed them to different amounts of sunlight. He also used a third plant as a control group, or a group in which no variables are manipulated to confirm the results. Roberto critiqued the work. Which problem did Roberto most likely identify? 1.The sample size is too small. 2.Too many variables are manipulated. 3.It is not possible to keep the conditions the same. 4.Controls should only be used in studies of animals.
Answer:
The sample size is too small
Explanation:
In this case, the sample size refers to the number of plants in the experiment. Only one plant was assigned to each group. This sample size is too small to derive any statistically significant meaning from the outcome of the experiment.
If a larger sample size is used, a more accurate mean value will be obtained. It will also be easy to identify any outliers that could cause the data to be skewed if the sample size were to be smaller. Use of larger sample size decreases the margin of error in the experiment.

How many grams of Ag are there in 0.901 moles of Ag?
Answer:
The answer is 0.0092705727916105. We assume you are converting between moles Ag and gram.
Explanation:
Answer:
97.2 g Ag
Explanation:
Molar mass of Ag = 107.86 g/mol
0.901 moles Ag x (107.86 g Ag/ 1 mol Ag) = 97.2 g Ag
Moles cancel and you are left with grams of Ag. Multiply 0.901 by 107.86 to find grams of Silver.

The outer shell of this element was determined as illustrated here. It must be a _____.
: light metal
: heavy metal
: non metal
: noble gas
The outer shell of the given element was determined as illustrated must be a noble gas. Therefore, option D is correct.
What are noble gases?Noble gases can be described as the 6 elements that are organized in group 18 of the modern periodic table. The noble gases are Helium, Neon, Argon, Krypton, Xenon, and Radon.
Under standard temperature and pressure, noble gases exist in the gaseous form and possess low reactivity. Therefore, noble gases are also referred to as inert gas. All the noble gases exhibit stable electronic configurations in their valence shell that are completely filled. Noble gases generally exist as monoatomic.
The general outer configuration of the noble gases can be written as ns²np⁶, n is the principal quantum number. Therefore, the given electron dot diagram has eight electrons in its valence shell so it is representing a noble gas.
