Answer:
Explained below
Explanation:
Newton's law of inertia states that An object at rest will remain continue at rest or if in motion, will continue in motion unless in both cases it is acted upon by a net external force.
Now, If two forces on the rope are equal and opposite forces, then the net force on the rope will be zero and it will not move. Thus,balance force is present in the rope and the rope will remain at rest since the net force is zero or it will continue in motion if already in motion without stopping since net force is zero
However, if the forces are acting in the same direction, it will result in an unbalanced force which means that the net force will be equal to the sum of the two forces and this will result in a stronger force than even the 2 individual forces and consequently it will cause the rope at rest to move, or if the rope is in motion, it will cause it to stop.

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.

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.
Explanation:
Answer:
Fórmula química: SO2 estado=Gas
Punto de ebullición: -10 °C (14 °F)
Masa molar media: 64,06 g/mol
Punto de fusión: -72 °C (-97,60 °F)

Which sequence represents the relationship between temperature and volume as explained by the kinetic-molecular theory? higher temperature Right arrow more kinetic energy Right arrow more space between particles Right arrow higher volume higher temperature Right arrow less kinetic energy Right arrow less space between particles Right arrow higher volume higher temperature Right arrow more kinetic energy Right arrow less space between particles Right arrow lower volume higher temperature Right arrow less kinetic energy Right arrow more space between particles Right arrow lower volume
Answer:
higher temperature → more kinetic energy → more space between particles higher volume
Explanation:
Kinetic Molecular Theory states that gas particles exhibit perfectly elastic collisions and remain in constant motion. Absolute temperature is directly proportional to the average kinetic energy of gas particles.
The following sequence represents the relationship between temperature and volume as explained by the kinetic-molecular theory:
higher temperature → more kinetic energy → more space between particles higher volume

What are the 6 types of chemical reactions?
Answer:
Explanation:
Six common types of chemical reactions are: synthesis, decomposition, single-displacement, double-displacement, combustion and acid-base reactions .
Chemical reactions can be classified into six main types based on their characteristics. The six types of chemical reactions are Combination (Synthesis) Reaction, Decomposition Reaction, Displacement (Single Replacement) Reaction, Double Displacement (Double Replacement) Reaction, Combustion Reaction, and Redox (Oxidation-Reduction) Reaction.
Combination reactions involve the union of two or more substances to form a more complex compound. Decomposition reactions involve the breakdown of a single compound into simpler substances.
Displacement reactions occur when an element displaces another element in a compound, resulting in the formation of a new compound and a different element. Double displacement reactions involve the exchange of ions between two compounds, leading to the formation of two new compounds.
Combustion reactions occur when a substance reacts rapidly with oxygen, producing heat and light. Understanding these different types of chemical reactions helps in predicting and understanding the behavior of substances during chemical transformations.
Therefore, the six types of chemical reactions are Combination (Synthesis) Reaction, Decomposition Reaction, Displacement (Single Replacement) Reaction, Double Displacement (Double Replacement) Reaction, Combustion Reaction, and Redox (Oxidation-Reduction) Reaction.

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.

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.

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.
