<span>Lyle stirs 5.0 grams of salt into a beaker of water. He then adds 15.0 grams of pure iodine to the mixture. If the total mass of the new mixture is 225 grams, what is the mass of the water

Answer:
two
Explanation:
When two distinct elements are chemically combined, chemical bonds form between their atoms. the result is called a chemical compound
<h2>ANSWER:</h2><h2>_____________________________________</h2><h3>
Why is there no reaction between silver and copper (II) nitrate?</h3>
For the reaction to occur, it is necessary that the metal which replaces the metal from the compound LIES above that metal in the ELECTROCHEMICAL SERIES(ECS). The metal in the compound here is Copper (II) nitrate where as the metal trying to displace is silver. Silver lies below the copper in a ECS, that means Copper is more reactive than silver. The reaction is not possible because more reactive metal displaces less reactive metal from its compound, and silver is LESS reactive than copper so it cant displace the copper from copper nitrate.
<h2>_____________________________________</h2><h2>THE ELECTROCHEMICAL SERIES IS ATTACHED BELOW</h2>
Here,
Heat gain by the first sample of water + Heat lost by the second sample of water is equal to zero (0).
Now, Mass of water sample one = 108 g (given)
Mass of water sample two = 66.9 g (given)
Temperature for water sample one =
Let, temperature for water sample two =x
And, final temperature =
Now,
where, = final temperature
= initial temperature
Substitute all the given values in above formula:
[tex x =84.81^{0}C [/tex]
1. 1086.04 mmHg
2.70.213 mmHg
3. 95.954 kPa
<h3>Further explanation</h3>
Pressure (P) is the force applied per unit area
Can be formulated :
P = pressure (SI=Pascal(Pa))
F= force applied (N)
A=area(m²)
The unit of pressure can be expressed in atm, mmHg, or Pascal
