Answer :
(A) Br₂ (s) : molecular solids
(B) AgCl (s) : ionic solids
(C) S (s) : atomic solids
(D) CH₄ (s) : molecular solids
Explanation :
Molecular solids : It is defined as the solids in which they are held together by covalent forces, dipole interactions as attractive forces etc.
Ionic solids : It is defined as the solids in which the atoms composed with oppositely charged ions.
Atomic solids : It is defined as the solids in which the molecules are held together by covalent forces and also includes pure substance.
(A) Br₂ (s)
It is molecular solids because they are held together by covalent forces.
(B) AgCl (s)
It is ionic solids because in this atoms composed with oppositely charged ions.
(C) S (s)
It is atomic solids because it is a pure substance.
(D) CH₄ (s)
It is molecular solids because they are held together by covalent forces.
The particles are always in motion but not much and the particles are moving slower because said rock is a solid but if said rock was a gas the particles would move much faster and farther this is due to the gaining and loss of energy (i hope that makes sense)
Answer:
pH = - log [2.12 x 10^-3]
what is the log of 2.22 x 10^-3]
Take the opposite of that,
That is the pH, now, just make certain you use the correct significant figures.
Explanation:
Ocean currents move both warm and cool water across many miles. Warm water can be carried to a cooler place like Alaska. It can bring warmer temperatures as well as warmer water to Alaska. Just like the warm water, cold water can do this as well. If cold water moves from Alaska to The Gulf of Mexico, it can cause the water and air to cool. As air travels over the ocean water vapor can condense into it. The current’s flow depends on what variables are in play. There are many different currents that connect together to heat up and cool off as they move.
Answer:
ANIMAL CELL
Animal cells are generally small in size.
They don't have a cell wall
Except the protozoan Euglena, no animal cell possesses plastids.
Vacuoles in animal cells are many, small and temporary.
Animal cells have a single highly complex and prominent Golgi apparatus.
Animal cells have centrosome and centrioles.
PLANT CELL
Plant cells are larger than animal cells.
The plasma membrane of plant cells is surrounded by a rigid cell wall of cellulose.
They have Plastids
Most mature plant cells have a permanent and large central sap vacuole.
Plant cells have many simpler units of Golgi apparatus, called dictyosomes.
Plant cells lack centrosome and centrioles.
Hope this helps!
