One of the functions of scaffolds in tissue engineering is letter b. cells grow into the correct shape. Scaffolds used in tissue engineering have biomaterials with biological attributes <span>that will enhance cell attachment </span>and topography where cells morph and align.
Answer:
a. NH3+ HCl → NH4Cl
c. 2O3 → 3O2
Explanation:
A redox reaction is a reaction in which there is loss or gain of electrons. As a result of that , there is a change in the oxidation number of the species involved in the reaction.
If we look at the species shown in the answer, there isn't any change in oxidation number as we move from left to right hence they are not redox reactions.
Redox reactions lead to change in oxidation number of species from left to right.
Answer:
The answer to your question is 2.1
Explanation:
Data
Molarity = 1 l
mass = 120 g of NaCl
moles = ?
Formula
Process
1.- Calculate the number of moles of NaCl
Molecular weight NaCl = 23 + 35.5 = 58.5 g
2.- Calculate the number of moles using proportions
58.5 g of NaCl --------------- 1 mol
120.0 g of NaCl --------------- x
x = ( 120 x 1) / 58.5
x = 2.1 moles
3.- Calculate Molarity
Substitution
Simplification and result
Molarity = 2.1
The answer is A. 1350
(ALL NUMBERS Except the grams is given from the equation)
18.21mol HNO3/1 * 1mol MgN206/2mol/ 2mol HNO3 * (molar mass-->)148.30 MgN206/ 1mol MgN2O6
You multiply 18.21HNO3* 1mol MgN2O6 * 148.30MgN2O6
Then divide it by the 2mol HNO3 to get 1350
Chemical equilibrium is the point at which the forward reaction rate and the reverse reaction rate are <u>identical</u>.
