Answer:
11.6g of NH₃(g) have to react
Explanation:
For the reaction:
4 NH₃(g) + 5 O₂(g) → 4 NO(g) + 6 H₂O(g) ΔH = -905kJ
<em>4 moles of ammonia produce 905kJ</em>
Thus, if you want to produce 154kJ of energy you need:
154kJ × (4 mol NH₃ / 905kJ) = <em>0.681moles of NH₃. </em>In mass -Molar mass ammonia is 17.031g/mol-
0.681mol NH₃ × (17.031g / mol) = <em>11.6g of NH₃(g) have to react</em>
The third one is correct, not sure abt another one
Pyridoxine contains 11 hydrogen atoms, 8 carbon atoms, 3 oxygen atoms, and 1 nitrogen atom. The chemical formula would be C8H11NO3. A chemical formula of a substance tells the number of atoms of the elements that is involved in the compound. Pyrodoxine is commonly known as vitamin B6. It is mostly found in food like meat, whole grains, nuts and avocados. Also, it is can be present in dietary supplements. It has a number of important functions in the body. Dietary supplements are manufactured to prevent vitamin B6 deficiency. Also, it is used in treating a specific type of anemia or the lack of red blood cells.
Answer:
The answer is
<h2>3.68 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
<h3>
</h3>
From the question
mass of substance = 12.50 g
volume = 3.4 mL
The density of the substance is
We have the final answer as
<h3>3.68 g/mL</h3>
Hope this helps you
An ionic compound that results from the reaction of an acid and a base is called a(n) salt. the cation in this compound comes from the base while the anion comes from the acid.
When an acid and a base are together, they react to counteract each other's effects and create a salt.
Water is created when the OH(-) anion of the base and the H(+) cation of the acid mix.
A salt is a substance that is created when an anion from an acid and a base combine.
Common table salt, NaCl, is created when sodium hydroxide and hydrochloric acid are combined.
The positive ion (cation) of a base and the negative ion (anion) of an acid make up a salt.
A neutralizing reaction occurs when an acid and a base interact. Additionally, sodium chloride, generally known as table salt, is referred to as salt.
