This question is a critical question. as we all know, when energy is added to any state of water, the particles move faster. and when energy is taken away from any state of water, the particles reduce speed. same with the particles of air. when energy is added; they move faster. when energy is removed; they move slower. so the answer is they move faster
The answer is C. 2, 1, 2, 1
This way both sides of the reaction have the same amount of atoms of each element:
Na = 2 atoms
Cl = 2 atoms
Ca = 1 atom
F = 2 atoms
following the law of conservation of mass which says the mass remains constant, it can't be added or removed
Provided the dots represent time-lapse snapshots of an object's motion from left to right, then
(a) The underlying object is slowing down because the distance between adjacent snapshots (dots) decreases with time
(the answer is intentionally reworded to avoid sounding nonsensical)
The electrical charge of an atom is determined by the number of electrons it has gained/lost. Electrons have a negative charge. We will let "e" be the amount of electrical charge carried by an electron.
If the atom has not lost or gained any electrons, it has a neutral, or zero, charge.
If the atom has 2 extra electrons, the atom is overall negatively charged with a charge equal to -2e.
If the atom has lost 2 electrons, the atom is overall positively charged with a charge equal to +2e.
If you want the charge quantities in Coulombs, use the conversion rate:
e = 1.6×10⁻¹⁹C
Answer:
Dividing mass by volume
Explanation:
Density of a substance is defined as the mass per unit volume of the same substance. Assuming the mass of the substance is 10 Kg and it displaces volume equivalent to 5 cc then its volume will be 10/5= 2 Kg/cc. Basically, to get the density of a substance, we divide the given mass by volume
