Answer:
A reaction rate is a measure of how fast a reactant disappears or a product forms during a reaction.
Explanation:
It is usually defined as the change in concentration per unit time:
Δ(concentration)/Δt
The units are (moles per litre) per second.
In symbols, the units are mol/(L·s) or mol·L^-1 s^-1.
Red phosphorus and white phosphorus are solid is a physical property
Answer:
0.85M
Explanation:
Given parameters:
Mass of CuCl₂ = 400g
Volume of water = 3.5L
Unknown:
Molarity of the solution = ?
Solution:
Molarity is one of the ways of expressing the concentrations of a solution. It is defined as the number of moles per unit volume of a solvent.
Molarity =
To find the number of moles of CuCl₂;
Number of moles =
Molar mass of CuCl₂ = 63.6 + 2(35.5) = 134.6g/mol
Number of moles = = 2.97moles
Molarity = = 0.85M
Answer:The value of equilibrium constant is .
Explanation:
Expression of an equilibrium constant is given as:
The value of equilibrium constant is .
Hi there!
To find the volume of a rectangular prism, we need to multiply all of its dimensions together.
In this case, we would multiply the length, width, and depth:
4 * 4 * 8
= 16 * 8
= 128
So, the answer is 128 cubic feet.
Hope this helps!
