Answer:
We also need the nitrogen intake
Explanation:
The nitrogen balance is the difference between the nitrogen intake and nitrogen excreted. If this calculation is positive, the body grow; if it is negative, the body is decreased.
Answer:
See the answer below
Explanation:
A neutralization reaction is a reaction that involves acid and base with the production of salt and water as the end products. An example is as below:
HCl + NaOH --> NaCl + H2O
The salt produced here is NaCl. In solution, NaCl will ionize as:
Hence, the salt's positive ion (Na+) was contributed by the base (NaOH) while its negative ion (Cl-) was contributed by the acid (HCl).
In a neutralization reaction involving Ba(OH)2 and HNO3, the salt's positive ion comes from the base and the negative ion comes from the acid. In the molecular and net ionic equations, spectator ions, which are unaltered in the process, are included and excluded respectively.
In a neutralization reaction, an acid and a base react to produce water and a salt. Taking the provided reaction of Ba(OH)2 (aq) + 2HNO3(aq) → Ba(NO3)2(aq) + 2H₂O(1), the salt's positive ion (Ba²+), also known as the cation, comes from the the base, Ba(OH)2. The salt's negative ion (NO3-), also known as the anion, comes from the acid, HNO3. This reaction also represents a molecular equation where all reactants and products are represented as neutral substances. A net ionic equation would exclude the spectator ions, ions whose presence is required to maintain charge neutrality but are chemically and physically unaltered by the process.

Answer and explanation;
Ions are formed when an atom looses or gains electrons.
-Ionic charges are created when there is an imbalance of protons and electrons on an atom. Since we can not change the number of protons on the nucleus of an atom, a positively charged ion will be created when there are fewer electrons than protons (in other words when an atom looses electron). A negatively charged ion is formed or created when there are more electrons than protons in an atom (when an atom gains electrons).
-When electron are added, you are adding more negative charge and thus, results in the creation of a negative ion (anion), and when electrons are being lost by an atom, one is removing negative charge, resulting in creation of a positive ion (cation).
B. volume and temperature only
C. volume and pressure only
D. pressure, volume, and temperature
Answer:
The correct option is D
Explanation:
The combined gas law is a combination of the three gas laws; Boyle's law, Charles' law and Gay-Lussac's law. It describes the relationship of the product of the pressure, volume and temperature of a gas to a constant as shown in the formula below
P₁V₁/T₁ = P₂V₂/T₂
Where P₁ is the initial pressure
V₁ is the initial volume
T₁ is the initial temperature (in Kelvin)
P₂ is the final pressure
V₂ is the final volume
T₂ is the final temperature (in Kelvin)
