Answer:
not a solid/ dissolved in water/ through melting because the ion's electrons have to be able to move freely and they can't do this when they are solids. they can occur
In order for substances to conduct electricity, their ions must be mobile and capable of carrying a charge. Most commonly, substances conduct electricity by having freely mobile electrons or dissolved ions in their atomic structure.
In order for substances to conduct electricity, their ions must be mobile and capable of carrying a charge. Most commonly, substances conduct electricity by having freely mobile electrons or dissolved ions in their atomic structure.
For example, in metals, some electrons are not bound to individual atoms, allowing them to move through the material and carry a charge. Salty water and other conductive materials contain dissolved ions that can also move and conduct electricity.
In contrast, insulators like glass have bound electrons and ions that cannot move easily, making them poor conductors of electricity.
#SPJ3
She mixes two solutions and measures their pH before and after.
She asks her lab partner which base he thinks is hardest to study. <-- my answer
She measures the temperature of a solution before and after adding H2SO4.
Answer: Option (c) is the correct answer.
Explanation:
An experiment conducted by following a detailed and organized series of steps in such a manner that its result will reject or validate the hypothesis.
For example, using an acid-base indicator will help to measure the pH of a solution.
A scientific reaction is performed in controlled conditions with proper precautions unless it could be dangerous to perform the experiment.
Therefore, we can conclude that she asks her lab partner which base he thinks is hardest to study is not a scientific experiment.
B. A, B, C, D
C. D, B, C, A
D. A, C, B, D
B. specific heat
C. freezing point
D. solubility
B. Temperature and volume
C. Pressure and volume
D. Pressure and temperature
Answer:
D. Pressure and temperature.
Explanation:
The answer is D because when water molecules (H2o) have heat and pressure added it will boil. For exampe if your cooking pasta, you add water to your pan and when you add heat and put the lid of the pan it will boil.
A reactionarrow simply indicates that something has changed and that one thing has become another.
A chemicalreaction is a process that converts one or more substances, known as reactants, into one or more different substances, known as products.
Chemical elements or compounds are examples of substances. A chemical reaction rearranges the constituent atoms of the reactants to produce various products.
The most important characteristics of events occurring in the universe are chemical reactions.
Plants grow, fruit development, and biodegrade towards becoming rich in nitrogen for new plants through chemical reactions.
Humans along with all other animals reproduce, digest, grow, heal, and think as a result of chemical reactions.
The arrow connects the old and new things (the thing that formed). An equation of reaction employs the reactionarrow. The reactant is the thing that reacted.
Thus, this is the chief meaning of the arrow in a chemicalreaction, the it shown the reactants combined to form products.
