I will have to go with carbon monoxide
Lustrous (shiny)
Good conductors of heat and electricity.
High melting point.
High density (heavy for their size)
Malleable (can be hammered)
Ductile (can be drawn into wires)
Usually solid at room temperature (an exception is mercury)
Opaque as a thin sheet (can't see through metals)
<u>Answer:</u> The pH of the cleaning compound is 10.44
<u>Explanation:</u>
pH is defined as the negative logarithm of hydrogen or hydronium ion concentration that are present in a solution.
The equation representing pH of the solution follows:
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
We are given:
![[H^+]=3.6\times 10^{-11}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D3.6%5Ctimes%2010%5E%7B-11%7D)
Putting values in above equation, we get:


Hence, the pH of the cleaning compound is 10.44
Aldehydes oxidise to form carboxylic acids
Answer:
CH 4 (g) + 20 2 (g)- CO 2 (g) + 2H 2 0 (g)
Explanation:
A balanced chemical reaction equation is one in which the number of atoms of each element on the reactants side is equal to the number of atoms of each element on the product side.
We can balance the equation by carrying out an atom count, that is, we count the atoms of each element on the reactant side and on the products side.
For instance;
Carbon has one atom on both sides of the reaction equation
Oxygen has four atoms on both sides of the reaction equation
Hydrogen has four atoms on both sides of the reaction equation.
Hence we can say that the reaction equation is balanced.
