What is 345238 plus 11000 plus 5000 plus 1200 plus 1000 plus 1500 plus 2000 plus 35 plus 30 plus 216330 plus 8035306 equal to?
345238+11000+5000+1200+1000+1500+2000+35+30+216330+8035306 =8618639 All the operations are addition so this can all be added in one step.
What is 1 plus 2 plus 3 plus 4 plus 5 plus 6 plus 7 plus 8 plus 9 plus 9 plus 9 plus 9 plus 9 plus 0?
These numbers all add up to 81.
What is 300000000 plus 9000000 plus 200000 plus 70000 plus 30 plus 1?
300000000+9000000+200000+70000+30+1 =309270031 All the addition can happen in the same step. When all the operations are the same it can be done that way.
What is 813 plus 813 plus 812 plus 808 plus 806 plus 805 plus 804 plus 804 plus 804 plus 803 plus 802 plus 796 plus 792 plus 792 plus 783?
813+813+812+808+806+805+804+804+804+803+802+796+792+792+783 =12037 All the operations are addition so all the adding can happen in one step.
How many terms are in -3x2 plus 2y2 plus 5xy-2y plus 5x2-3y2?
All six of them
What is the equation for potassium sulfate and barium bromide?
When they react K2SO4 and BaBr2 they'll give 2KBr and BaSO4: SO42-aq + Ba2+aq ---> (BaSO4)s ('s' = solid = precipitating bariumsulfate) 2K+ and Ba2+ are spectator ions (all 'aq' = hydrated in solution)
What ions are iso-electronic with the barium ion?
Cesium(I), Cs+1 is an iso-electronic ion to Ba2+ and also iodine, I-1 ions and xenon, Xe0 atoms are iso-electronic to Ba2+ ions.They all have the [Xe] electron configuration: [2, 8, 18, 18, 8], 0
What is the the difference between soluble and solubility?
Solubility is normally measured as the amount of a substance that can dissolve in a solvent and is measured in units of (amount of substance)/(volume of solvent).Barium nitrate, for example, has a solubility of 0.105 moles/litre in water, or it can also be expressed as 27.3g/litre.The solubility product is an equilibrium constant for the process:salt (solid) cations (aq) + ions (aq)As the activity of the solid is taken to have a value of 1, the solubility product is the result of multiplying the concentrations of the dissolved ions at the solid's maximum solubility.The solubility product (Ksp) can be thought of as a more general expression of the solubility of a substance. To obtain the solubility product, we multiply the concentrations (mol/litre)* of ALL the ions that result from the substance dissolving when they are at their maximum concentration.In the case of barium nitrate, we have:Ba(NO3)2 ---> Ba2+ + NO3- + NO3-So the solubility product , Ksp = [Ba2+][NO3-][NO3-] = [Ba2+][NO3-]2The experimentally determined value of the solubility product for Barium Nitrate is 4.64×10-3.For barium nitrate dissolving in pure water, [NO3-]= 2[Ba2+], so we can writeKsp = [Ba2+][NO3-]2 = 4[Ba2+]3 = 4.64×10-3Solving this, [Ba2+] = 0.105 mol/litreAs [Ba2+] equals the concentration of barium nitrate that is dissolved, this is the solubility of barium nitrate in pure water.The usefulness of the solubility product is that we can use it to look at the effects of ions from other sources than the salt. For example, if we try to dissolve barium nitrate in 10 molar nitric acid, we use the same expression as before:Ksp = [Ba2+][NO3-]2 = 4.64×10-3But this time [NO3-] = 10 mol/litre (approx), as that is already in solution, so:100 [Ba2+] = 4.64×10-3[Ba2+] = 4.64×10-5The solubility of barium nitrate in 10M nitric acid is 4.64×10-5 Mol/litre, MUCH less than its solubility in pure water, and not something that you could determine from the solubility alone.*Strictly, we should use activity rather than concentration.
Is there a Adobe After Effects that's not extremely expensive?
nothing is cheap that is as good as After Effects, but there are free ways to get After effects.
What volume of 0.131 M BaCl2 is required to react completely with 42.0 ml of .453 MNa2SO4. This is the net ionic equation for the reaction. Ba2 plus plus SO42---- BaSO4. Correct answer equals 145 ML?
first of all, you need to recognize that one mole of Na2SO4 is reacting with one mole of BaCL2. so find the moles of the NaSO4, then you automatically have the moles of the BaCL2. if you get the moles of the BaCL2, its easy to calculate the volume of it because you already have the MOLARITY. good luck
Is Li2CO3 a electrolyte?
Yes. All salts of group 1 ions are soluble. Ba2+ is an exception to the "sulfates are soluble" rule, and neither chromium nor phosphate appears on the solubility rules.
What is solubility product constant?
At saturated solution of (partly) insoluble salt (imaginable: A2B) the following Equilibrium exists:(A2B)s --> 2A+ + B2-The thermodynamic Equilibrium constant Ksol equals: Ksol = [A+]2*[B2-] , the square hooks symbolise the ion concentration in mole/L. Note also the power in superscript [A]power which is equal to the number of ions in the (standardised) reaction equation. Further it should be noted that the amount of solid salt (A2B)s is not in the nominator of this Equilibrium equation, Ksol = [A+]2*[B2-] and that's why it is called (Equilibrium) solubility product.
Are all C plus plus classes subtypes?
no
What is 8 plus 8 plus 8 plus 6 plus 6 plus 16?
8+8+8+6+6+16 =52 All the addition can happen in the same step. When the operations are all the same you can do this.
What Is The Precipitate Of Sodium Hydroxide Magnesium Sulphate?
Magnesium Hydroxide since in the Solubility Rules it states that "All hydroxides are insoluable exceptcompounds of the alkali metals, Ca2+, Sr2+ and Ba2+" and since Magnesium is not in any one of those on the list Hydroxide is insoluable and therefore the precipitate.
What is the answer of 1 plus 12 plus 123 plus 1234 plus 12345 plus 123456 plus 1234567 plus 12345678 plus 123456789 plus 12345678910 plus 1234567891011 plus 123456789101112?
