Water has a density of 0.9982 g/mL, so it will sink.
Answer:
33 degrees
Explanation:
The critical angle for a light ray moving from a denser medium with refractive index 
to a second medium with refractive index 
is given by
In this case, the critical angle occurs when light moves from diamond to water. The index of refraction of the two materials are:
for diamond
for water
So the critical angle is
Answer: a. the inhibitor will decrease the rate of reaction.
Explanation: The rate of the reaction is affected by addition of inhibitors which are also called as negative catalysts as they decrease the rate of reaction unlike catalysts which enhance the rate of reaction.
Inhibitors delay, slow or prevent the chemical reactions by binding with the substrate or the catalyst and hence prevent them to function normally.
Answer:
liquid junction potentials
when a cell contains a boundary between two electrolytic solutions of different composition or concentration, a liquid junction potential is developed due to the "diffusion of the various components at characteristic rates in the boundary zone."

Answer:
You should start with 63.54 grams of copper.
Explanation:
The chemical reactions are processes in which the nature of the substances changes, that is, from some initial substances called reactants, totally different ones called products are obtained.
In the chemical reaction, the formulas of reagents and products appear preceded by numbers (the stoichiometric coefficients) that indicate the proportions according to which the transformation occurs. So you can say that stoichiometry establishes relationships between the molecules or elements that make up the reactants of a chemical equation with the products of said reaction. The relationships that are established are MOLAR relationships between the compounds or elements that make up the chemical equation: always in MOLES.
The stoichiometric coefficients of a chemical equation are due to the fact that the atoms present before the reaction must be the same after the reaction, although they will have been rearranged to produce new substances.
If you want 2 moles of silver (Ag), for stoichiometry of the reaction you need a moles of copper Cu. Being the molar mass of copper Cu 63.54 g / mole, then:
1 mole*63.54 g/mole= 63.54 g
