Answer:
1,39 L
Explanation:
Charle's Law states that the volume of a fixed amount of gas <em>maintained at constant pressure</em> is directly proportional to the<u> absolute temperature</u> of the gas, for a constant amount of gas we can write:
As the pressure of the balloon doesn't change, we can use Charle's Law to solve the problem. Firs we change the given temperatures to absolute temperature units ( °K), using the following relations:
°K=273+°C
°K=5/9(°F-32)+273
Therefore:
V1=1.5 L, T1=273+25=298°K
V2=?, T2=5/9(36-32)+273=275,2°K
The new volume of the balloon is 1,39 L.
<u>Explanation:</u>
Phosphorus and oxygen atoms are considered as non-metals and two non-metals usually form covalent bonds.
A covalent bond is formed when sharing of electrons takes place between the atoms forming a bond.
The nomenclature of a covalent compound is given by:
- The less electronegative element is written first.
- The more electronegative element is written then, and a suffix is added with it. The suffix added is '-ide'.
- If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on..
From the two atoms, less electronegative atom is phosphorus and thus, is written first.
Naming of the given compound are as follows:
1. = The name given to this compound is tetraphosphorus heptoxide
2. = The name given to this compound is diphosphorus pentoxide
3. = The name given to this compound is diphosphorus tetroxide
4. = The name given to this compound is phosphorus monoxide
