3) once dissolved, covalent bonded compounds stay as separate molecules, then it is stated that the significant species current in the systems is the molecule. The molecules of acetone room surrounded (sovated) through the molecule of water.

You are watching: Major species present when dissolved in water

This together opposed come the situation of ionic compounds that ionize. Once a compound together NaCl disappear in water, the ionizes completely, for this reason the significant speceies room not NaCl formulas, however the ions Na⁺ and also Cl⁻, not molecules.

That leader to the chrischona2015.org: the significant species present when acetone is dissolved in water is the molecule of acetone (you perform not should state the truth that the molecules of water are part of the solution, since that is no the target that the question).

93.0 mL that O2 gas is accumulated over water at 0.930 atm and also 10.0 C.what would be the volume that this dried gas at STP
ExtremeBDS <4>
Let us assume that the oxygen behaves as perfect gas such that we have the right to use the best gas equation to settle for the number of moles of O2. PV = nRT ; n = PV/RTSubstituting the well-known values, n = (0.930 atm)(93/1000 L) / (0.0821 L.atm/mol.K)(10 + 273.15K) n = 3.72 x 10^-3 molsAt STP, the volume of each mol that gas is equal to 22.4 L. Volume = (3.73 x 10^-3 mols) x (22.4 L/1 mol) volume = 0.0833 together or 83.34 mL

Minerals with the silicon-oxygen structure displayed in figure 2-1 space classified right into what group?
Snowcat <4.5K>

chrischona2015.org : alternative D) Silicates.

Explanation : The minerals with the silicon-oxygen structures are classified as silicates.

As every the definition, A silicate is any kind of member the a family which has anions consists of silicon and also oxygen, generally they have the basic formula as .

It usually has a structure which has a main silicon ion which has a charge of (+4) while each oxygen has a fee of an unfavorable two (-2) and also thus each silicon-oxygen shortcut is same to one half (1/2) that the full bond power of oxygen. Therefore, it confirms the the chrischona2015.org is Silicates.

What is the percent the Cr in Cr2O3
IgorLugansk <536>
The portion of Chromium in Chromium Oxide is calculated together follow,Step 1: calculation Molar mass of Cr₂O₃,Cr = 51.99 uO = 16 uSo, 2(51.99) + 3(16) = 103.98 + 48 = 151.98 uStep 2: Secondly division molar fixed of just chromium with full mass of Cr₂O₃ and also multiply v 100.i.e. = 
*
 × 100 = 68.41 %So, the %age composition of chromium in chromium oxide is 68.41 %.
