Answer: Suspension mixture, colloidal mixture, and solution mixture
Explanation: These are the three types of mixtures, hopefully this helps.
The answer is: endothermic reaction.
This reaction is endothermic (enthalpy is higher than zero), which means that heat is added.
According to Le Chatelier's principle when the reaction is endothermic heat is included as a reactant and when the temperature increased, the heat of the system increase, so the system consume some of that heat by shifting the equilibrium to the right, producing more products.
Answer:
Correct answer is a. Ag(s) reacts spontaneously with 1M H+(aq).
Explanation:
A charasteristic of metals is that they lose easily electrons, cations tends to gain electrons to react and anions tends to lose or share electrons to react.
If you want to make a chemical reaction you must to mix a reagent that tends to lose electrons with other that tends to gain them.
In the statement (a) we have a metal that loses electrons and a cation that can obtain them, so is the right answer.
note that the other optios have :
b) Metal with metal cation, not react beacause left a medium of reaction.
c) Both loses electrons
d) Both tends to gain electrons.
Answer:
This question lacks options, the options are:
a. an observation
b. a dependent variable
c. an independent variable
d. a control
The answer is D. Control
Explanation:
According to the question, a student decides to conduct an experiment to determine the effect that the amount of time spent in sunlight has on the overall growth of a plant. The student keeps all other variables needed for the plants' growth in this experiment the same/identical. These variables kept identical by the student is called CONTROL OR CONSTANT.
One of the CONTROL is the amount of water given to each plant. The amount of water given to the two plants being tested must be the same. Hence, WATER in this experiment is a CONTROL VARIABLE.
Note that, the independent/manipulable variable is the amount of time spent in sunlight while the dependent/measurable variable is the growth of the plants.
Answer:
The answer is D control
Explanation:
FALSE
Light absorbed by objects, enters the eyes, and is refracted by the optic nerve in the retina.
B.
Light reflects off objects, enters the eyes, and is detected by the optic nerve in the retina.
C.
Light refracts off objects, enters the eyes, and is captured as a photograph by the lenses.
D.
Light reflects off objects, enters the eyes, and is detected by light-sensitive cells in the retina.
The human eye see objects through light reflects off objects, enters the eyes, and is detected by the optic nerve in the retina. The answer is letter B. The rest of the choices do not answer the question above.
