<u>Answer:</u> The name for is phosphorus trihydride.
<u>Explanation:</u>
Covalent compound is defined as the compound which is formed by the sharing of electrons between the atoms forming a compound. These are usually formed when two non-metals react.
is a covalent compound because sharing of electrons takes place between hydrogen and phosphorus. Both the elements are non-metals and hence, will form covalent bond.
The nomenclature of 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..
Hence, the name for is phosphorus trihydride.

<u>Answer:</u> The final temperature of water is 32.3°C
<u>Explanation:</u>
When two solutions are mixed, the amount of heat released by solution 1 (liquid water) will be equal to the amount of heat absorbed by solution 2 (liquid water)
The equation used to calculate heat released or absorbed follows:
......(1)
where,
q = heat absorbed or released
= mass of solution 1 (liquid water) = 50.0 g
= mass of solution 2 (liquid water) = 29.0 g
= final temperature = ?
= initial temperature of solution 1 = 25°C = [273 + 25] = 298 K
= initial temperature of solution 2 = 45°C = [273 + 45] = 318 K
c = specific heat of water= 4.18 J/g.K
Putting values in equation 1, we get:
Converting this into degree Celsius, we use the conversion factor:
Hence, the final temperature of water is 32.3°C
