Ik it's not magnesium because that was my first answer. The correct answer would be Sulfur. Sulfur is a non metal. All the other answers are good conductors of heat
When the student crushes sugar there there occurs an increase in the number of molecules or particles of sugar. This means that now more number of sugar particles (solute) are able to interact with water (solvent).
Therefore, there will be more number of collisions taking place between the solute and solvent molecules.
As a result, sugar will dissolve readily into water as there is an increase in interaction between solute and solvent particles.
Thus, we can conclude that when he crushes the sugar and then stirs it into the water then it will work as this leads to more interaction or collisions between the solute and solvent particles.
The volume is the space it takes up, which would be the same. The mass is measured as the weight, and the steel ball would be significantly heavier. Density is mass/volume, and if the steel has a larger mass, it will therefore have a higher density.
Answer:
The energy content of substances is related to the physical state in which the substance exists. Molecules of gases are always in motion as they possess very high kinetic energy, hence, they exist as gases. Liquid molecules are less energetic than gas molecules, hence they have less flow than gases. Solid molecules on the other are fixed at a place because they possess very low kinetic energy and can only vibrate about their fixed positions.
Explanation:
The three states in which matter exist are solid, liquid and gas.
Solids are made of molecules that are closely packed together and held together by strong intermolecular forces. The particles in a solid possess very low kinetic energy and are not free to move about but can only vibrate and rotate about their fixed positions.
Liquids particles are able to move about as they possess enough kinetic energy to limit or reduce the strength of the intermolecular forces binding them together. Thus, liquids can flow.
The particles in a gas are relatively far apart and possess kinetic energy more than the particles of a liquid or solid. The intermolecular forces binding particles of gas together are weak due to the very high kinetic energy of yhe gas particlest
Answer:
This question is incomplete
Explanation:
This question is incomplete but the completed question is in the attachment below. To determine the net ionic equation, one must first write the complete equation which is shown below
LiNO₃ + NaC₂H₃O₂ ⇒ LiC₂H₃O₂ + NaNO₃
The ionic equation represented from the above equation will be
Li¹⁺ NO₃⁻ + Na¹⁺ C₂H₃O₂¹⁻ ⇒ Li¹⁺ C₂H₃O₂¹⁻ + Na¹⁺NO₃¹⁻
Because the resultant NaNO₃ formed is an ionic compound (which does not form a molecule), the correct option from the options provided is the first option
