Answer:
the answer is ethanedioc acid
Answer:
The increase in kinetic energy that comes with higher temperatures allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions.
Explanation:
Answer:
236 g/mol
Explanation:
This question is asking to calculate the molar mass/formula mass of calcium nitrate tetrahydrate with the chemical formula: Ca(NO3)2 · 4H20. This is done as follows:
Atomic mass of the constituent elements are as follows:
Ca = 40
N = 14
O = 16
H = 1
Hence, in Ca(NO3)2 · 4H20.
= 40 + {14 + 16(3)}2 + 4 {1(2) + 16}
= 40 + {14 + 48}2 + 4{2 + 16}
= 40 + {62}2 + 4{18}
= 40 + 124 + 72
= 236
Hence, the molar mass of Ca(NO3)2 · 4H20 is 236g/mol.
Answer:
In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule in atomic or molecular orbitals. For example, the electron configuration of the neon atom is 1s² 2s² 2p⁶, using the notation explained below.
Explanation:
If you place a dialysis tubing permeable only to water filled with 10% sucrose solution into a beaker filled with a 30% solution of sucrose, you would expect for the water molecules from the 10% solution to pass through the membrane and dilute the 30% solution until the concentration in both solutions are equal. Thus, in equilibrium.
