Which of following is true of liquids?
Group of answer choices
The particles move at a high rate of speed
The particles have a medium amount of kinetic energy and slide past one another.
The particles vibrate in place.
The particles have a fixed volume and shape
Answer:
The particles have a medium amount of kinetic energy and slide past one another
Explanation:
If particles move at a high rate of speed its gas, and if they vibrate in place and they have a fixed volume and shape its probably a solid. So a medium amount of kinetic enery is correct.
which substances corrode copper?
what is the molecular shape of N2O2?
Answer:
If you're just looking at the Lewis Structure from the perspective of the octet rule, it does appear that the structure is correct. Dinitrogen always has a lone pair of electrons which could conceivably be used for dative bonding as you suggest. So from that perspective there appears to be nothing wrong at all - other than that it doesn't exist in nature in this way.
Explanation:
7. Some of the following sublevels do not exist. Cross out the ones that are not real.
1s 3d 4p 2d 3f 5s 6p 1p 2s 5g 4f 1f
Answer:
1f 3f 5g 1p 2d
Explanation:
There is only 4f and 5f orbitals.
G is not an orbital.
P orbital starts with 2p
D orbital starts with 3d
Explain the process of rainwater harvesting with its advantages .
Answer:
the environmental benefits of rain water harvesting
Explanation:
rainwater harvesting can reduce stormwater runoff a property by reducing stormwater runoff rainwater harvesting can reduce is term peak flow volume and velocity in local cricket stream and rivers thereby reducing the potential for stream Bank erosion
Explain the difference, with sketches, between the titration curves of monoprotic acid and a triprotic acid.
Answer:
A monoprotic acid has only one equivalence point in a titration curve while a triprotic acid has three equivalence points.
Explanation:
Monoprotic acids, HA, are acids that are able to donate one proton per molecule during the process of ionization or dissociation as shown below:
HA ----> H⁺ + A⁻
A triprotic acid is a polyproprotic acid, that is acids that can donate more than one proton per molecule during ionization. a triprotic acid can donate three protons per molecule during the process of ionization. The dissociation of a triprotic acid is shown below;
H₃A -----> H₂A⁻ + H⁺
H₂A⁻ ----> HA²⁻ + H⁺
HA²⁻ -----> A³⁻ + H⁺
The value Ka, is known as the acid dissociation constant. It is found by looking at the equilibrium constant for the dissociation of the acid. The higher the Ka, the more the acid dissociates
A titration curve is the plot of the pH of the analyte solution versus the volume of the titrant added as the titration progresses.
In a titration curve in which base is added to acid, the pH rises slowly until the equivalent point at which point the pH remains constant before it begins to rise again on the addition of more base.
In a titration curve of a monoprotic acid, there is only one region in which the equivalence point is obtained corresponding to the point of acid of dissociation of all its protons.
In the titration curve of a triproprotic acid, three equivalent points are obtained corresponding to the point of dissociation of each of three protons of the triprotic acid.
The titration curves are shown below
Convection currents in Earth's core transfer heat and material to the surface.
True or False?
Answer: False
Explanation: The plate tectonics move due to convection currents of the mantle; the cooler upper mantle descends while the hotter lower mantles ascend. The heat that drives these convection currents emanated from the core of the earth (not the sun).
Select odd one out.

II) Na
III) Cu
IV) Ag
Explanation:
0 is the odd one...............
and rest are metals and they lose electron and 0 gain electron and is non metal

Which substance will not conduct electricity?
A aluminium
B copper
C plastic
D steel
ОА. А
Explanation:
Covalent compounds (solid, liquid, solution) do not conduct electricity. Metal elements and carbon (graphite) are conductors of electricity but non-metal elements are insulators of electricity. Ionic bonds are the electrostatic attraction between positive and negative ions.

Specify the steps included in the sedimentary rock formation
Answer:
Sedimentary rocks are the product of 1) weathering of preexisting rocks, 2) transport of the weathering products, 3) deposition of the material, followed by 4) compaction, and 5) cementation of the sediment to form a rock. The latter two steps are called lithification.
