Answer:
324.554 K
Explanation:
Which can be converted back to °C by subtracting 273
Once again thus answer can be found using the gas law P1/T1 =P2/T2
Remember to convert to Kelvin before doing the calculations by adding 273
Answer:
The pH would be 1.
Explanation:
The pH of an acid can be found by using the formula pH = - log [H⁺]. This was a method developed to be able to measure the pH of substances.
Since the concentration of HNO₃ is 0.1 M, then it also means that the concentration of H⁺ ions is 0.1 M.
By substituting for the formula: pH of 0.1 M HNO₃ = - log [0.1]
= 1
Answer : Option 4) 
Explanation : is the only sample of matter which can be classified as a solution. As the solution can be defined as a liquid mixture which contains a minor component (the solute) that is uniformly distributed within the major component (the solvent).
In this case, the solute is 
which is dissolved in water which acts as an solvent. Also, it has a subscript which is aq. which means aqueous, is often given to the solution in which the solvent is water.
Therefore, is the correct answer.
Answer:
Explanation:
a) O (oxygen) but there's not enough info to determine the isotope
b) superscript-37 subscript-17 Cl
c) superscript-60 subscript-27 Co
d) superscript-57 subscript-26 Fe
e) don't know what you mean here
f) superscript-7 subscript-3 Li
Edit:
a) superscript-17 subscript-8 O
e) superscript-131 subscript-53 I
