Chemistry
1 answer:
ruslelena [56]3 years ago
6 0

Answer:

Option c and d

Explanation:

John Dalton. In 1808, John Dalton proposed a theory known as Dalton’s Atomic Theory. The theory was published in a paper titled “A New Chemical Philosophy”. This theory was new to that era

The 5 postulates of Daltons' atomic theory are:

1. All the matters are made of atoms.

2. Atoms of different elements combine to form compounds

3. Compounds contain atoms in small whole-number ratios

4. Atoms can neither be created nor destroyed . (This was later proven wrong )

5. All atoms of an element are identical and have the same properties (This was later proven wrong as atoms of same element may be different in case of elements having isotopes )

Therefore, options c and d are the answer.

A gas occupies 2.22 l at 3.67 atm. what is the volume at 1.94 atm?
Iteru [2.4K]
According to Boyle's law, volume is inversely proportional to pressure. thus P=k/V
Therefore PV=k
P1V1=P2V2
In the question above,
P1=3.67atm
P2=1.94atm
V1=2.22L
V2=?
Thus substituting for the values in the gas equation;
3.67atm*2.22L=1.94atm*V2
V2=3.67atm*2.22L/1.94atm
=4.21L

Gaseous vapor observed when handling dry ice (solid co_2 ​2 ​​ ) physical or chemical
Nadya [2.5K]
<span>Dry ice is frozen carbon dioxide. It is easy to assume that the fog surrounds dry ice is carbon dioxide returning to it's gaseous however, you can not see that process. The vapors you see is the water molecules in the air condensing as a result of the cooling or energy removal by the dry ice. When energy is removed from water molecules they become colder and move slower than water in a gaseous. Similar to clouds in the air, the water condenses into a form that you can see.</span>

What is the isotope notation for an ion of silver-109 with a charge of positive 1
Arisa [49]

Answer:

The isotope notation for an ion of silver-109 with a charge of positive 1 is _{47}^{109}Ag^{1+}.

Explanation:

The elements with same atomic number with different mass numbers are called isotopes.

The isotopes of silver is as follows.

_{47}^{109}Ag,_{47}^{107}Ag

From the above two isotopes have same atomic number and different mass number.

From the given,the isotope notation for an ion of silver-109 with a charge of positive 1

It can be represented is as follows.

_{47}^{109}Ag^{1+}

General representation of isotope is as in attachment.
