Answer:
pure copper does not react with acetic acid.
Answer:
Explanation:
The following are the order of point from oldest to most recent
1. Atoms are tiny indivisible particles that make up all mater.
it is Postulate of Dalton's atomic theory. this theory was put forward in 1803
2. Negatively charged electrons are embedded in a mass of positive charge.
In 1897 J.J Thomson discovered that atom consist of tiny negatively charged particles called electrons that are uniformly spread in +vely charged matrix this model called as plum pudding model.
3. Atoms consist of mostly empty space with a dense nucleus of positive charge.
While doing experiment on gold foil Rutherford presented a model in 1909 and stated that atom consist mostly empty space with dense nucleus.
4. Electrons occupy specific energy levels surrounding a positively charged nucleus.
Niels Bohr in 1913 put forward a model to explain atomic orbitals/energy level. This is a postulate of Bohr model.
5. Electrons move about a positively charged nucleus in clouds that are defined by probabilities.
In 1926 Erwin Schrödinger explain the wave function of electrons and its probability.
Answer:
The new volume is 66.3 mL
Explanation:
Boyle's law states that pressure and volume are inversely proportional, and that P1V1=P2V2
P1 = 0.428 atm
P2=1.55 atm
V1 = 240 mL
V2 = ??
(0.428)(240)=(1.55)(V2)
102.72 = 1.55x
x = 102.72/1.55 = 66.27 mL.
