Answer:
V = 2.75 L
Explanation:
Given that,
Mass of liquid glycerol, m = 3470 g
The density of liquid glycerol, d = 1.26 g/cm³
We need to find the volume of liquid glycerol.
We know that,
Density=mass/volume
We know that, 1 cm³ = 0.001 L
V = 2.75 L
So, the volume of liquid glycerol is 2.75 L.
Given:
AgCl (s) ===> Ag+ (aq) + Cl- (aq)
- negative entropy
H2O(g) ===> H2O(l)
- positive entropy
2Na (s) + Cl2 (g) ===> 2NaCl (s)
- positive entropy
Br2(l) ===> Br2 (s)
-positive entropy
They are identified to have positive or negative values of entropy based on the phases of the reactants and products.
I'm assuming this refers to nuclear fission, which is in fact used to create heat, causing steam to spin turbines.
In which case, Uranium atoms are split by absorbing neutrons inside the reactor of a nuclear power station.
The nuclear reaction occurring is known as alpha-decay, and during this process, an alpha particle is released from a heavy radioactive nucleus to form a lighter more stable nucleus. The alpha particle is equivalent to a helium nucleus, which means it contains 2 protons and two neutrons (net charge of +2)
The decay equation is:
Rn → Po + α
Answer:
The particles of matter are in constant motion.
Explanation:
Let us consider each statement:
1) Matter consists of only large molecules: No it is not necessary that matter consists of only large molecules, it depends upon the nature of matter.
2) Matter is made up of only charged particles: no the matter may have any kind of particles charged or uncharged.
3) The particles of matter are in constant motion: Yes according to kinetic theory the matter particles are in constant motion.
4)The particles of matter have zero kinetic energy: it is not possible.
