If you mean a mineral, then the correct answer would be c. non-living
Answer:
8.13 ×10²³ atoms
Explanation:
Given data:
Mass of magnesium = 32.45 g
Number of atoms = ?
Solution:
Number of moles of Mg:
Number of moles = mass/molar mass
Number of moles = 32.45 g/ 24 g/mol
Number of moles = 1.35 mol
Number of atoms:
1 mole contain 6.022×10²³ atoms
1.35 mol × 6.022×10²³ atoms/ 1mol
8.13 ×10²³ atoms
Answer:
Explanation:
Atoms are held together by covalent bonds when they share electrons between themselves.
Covalent bonds are bonds that are formed between non-metals usually with a low electronegative difference between them. In this bond type, two non-metals donate electrons which are shared between the combining atoms and this makes them both like the corresponding noble gases. The shared electrons is what forms the covalent bonds.
An example of covalent bond is HCl, H₂S, SO₂, CO₂, O₂ etc
The equilibrium constant could be found using the relationship Kaq = [H^+] [HCOO-]/HCOOH
<h3>What is the equilibrium constant?</h3>
The equilibrium constant is a value that shows us the extent to which reactants are converted into products. We know that a very high value of the equilibrium constant implies that the reactants are mostly converted into products.
Now we have the equation of the reaction as; HCOOH(aq)⇌H^+(aq) + 〖HCOO〗^- (aq). The equilibrium constant ca now be written in terms of Kaq.
Thus the equilibrium constant is;
Kaq = [H^+] [HCOO-]/HCOOH
