Answer:
Q < K for both reactions. Both are spontaneous at those concentrations of substrate and product.
Explanation:
Hello,
In this case, the undergoing chemical reactions with their proper Gibbs free energy of reaction are:
The cellular concentrations are as follows: [A] = 0.050 mM, [B] = 4.0 mM, [C] = 0.060 mM and [D] = 0.010 mM.
For each case, the reaction quotient is:
A typical temperature at a cell is about 30°C, in such a way, the equilibrium constants are:
Therefore, Q < K for both reactions. Both are spontaneous at those concentrations of substrate and product.
Best regards.
<u>Answer:</u> The symbol of the ion formed is 
<u>Explanation:</u>
An ion is formed when a neutral atom looses or gains electrons.
- When an atom looses electrons, it results in the formation of positive ion known as cation.
- When an atom gains electrons, it results in the formation of negative ion known as anion.
Electronic configuration is defined as the representation of electrons around the nucleus of an atom.
Number of electrons in an atom is determined by the atomic number of that atom.
The element present in Group 2-A and in period 4 is Calcium (Ca)
Electronic configuration of Ca atom: 
This atom will loose 2 electrons to attain stable electronic configuration similar to Argon element (noble gas)
The electronic configration of 
Hence, the symbol of the ion formed is
We use acids and bases in everyday life for cooking and cleaning
Answer:
One characteristic of a sample of matter that indicates it is a pure substance is the <em>homogeneity of the molecular structure</em><em>.</em>
Explanation:
If the structure is the same all throughout such as liquid water, it is said to be homogenous.
This answer to this question is the. Type of atoms in the molecule
