Answer:
Step 1: The answer is option (b) NaOEt
Step 2: The answer is option (k) OH-, H2O, heat then H3O
Step 3: The answer is option (a) heat, -CO2
Step 4: na (no reagent)
Explanation:
See the attached file for the explanation.
Pneumonia is caused when an H3 is positive to any form so therefore the answer would be the element of a pneumonia will be a positive 6392
The atomic mass of the element = 24.309547
<h3>Further explanation</h3>
Given
Isotopes of Mg
Required
The atomic mass
Solution
Atomic mass is the average atomic mass of all its isotopes
Mass atom X = mass isotope 1 . % + mass isotope 2.% ..
The atomic mass of the element(Mg) :
= 23.98504 . 0.7870 + 24.98584 . 0.1013 + 25.98259 . 0.1117
= 18.876226 + 2.531066 + 2.902255
= 24.309547
The answer is B 5.40 x 10^14 Hz
Answer:
That's not possible. When a limiting reactant is called out in a stoichiometry problem, what that means is there's enough of all the other reactants for the limiting one to be completely consumed in the formation of product/products
