Answer:
The answer to your question is: 24 grams of D
Explanation:
To answer this question we need to remember the Lavoisier law of conservation of mass, which says that in a chemical reaction matter is neither created nor destroyed.
This means that the amount of matter stays the same.
Then, the reaction is
A + B ⇒ C + D
26 g 12 g 14 g x
mass
of reactants 38 g ? mass of products, but it must be
equal to the mass of products
Then 14g + x = 38
x = 38 - 14
x = 24 g of D
Hi!
The generic equation showing how a weak base ionizes water is the following:
B(aq) + H₂O(l) ⇄ BH⁺(aq) + OH⁻(aq)
A base is described as weak when its dissociation is difficult and isn't complete. Weak Bases are chemical compounds that accept protons from water, to form the conjugate acid and the OH⁻ ion. The pH of the solution of a weak base is higher than 7. Some weak bases include ammonia (NH₃), Aluminum Hydroxide (Al(OH)₃) and Sodium Acetate (CH₃COONa).
Have a nice day!
Answer:
The compound, H₂O, will not be found on the periodic table. This is because the periodic table only consists of individual elements. That being said, the elements found within H₂O are located on the periodic table. H₂O consists of hydrogen, denoted by the symbol "H", and oxygen, denoted by the symbol "O". The subscript (the 2) tells us that there are 2 hydrogen atoms located in the H₂O molecule.
Hydrogen is the first element listed on the periodic table and can be found in the top leftmost position. Oxygen is the eighth element on the periodic able and is located in the second row at the top right.
I don't have a graph but here's what I think. The relationship is that the volume will change depending on the temperature. So think of water for an example. The volume of it will stay the same at room temperature, but if you put a glass of it in the freezer for a few hours, take it out, measure the volume, the volume would have changed greatly. Or heating and evaporating the water will do the same.
