What is conc of water?
The concentration of water is typically measured in terms of its molarity, which is equal to 55.5 mol/L at room temperature. In other terms, water makes up approximately 55.5 moles in a liter of pure water.
Why the conc h2so4 cant be used in preparation oh h2s?
h2so4 being good oxidising agent oxidises the h2s to h2o and free sulphur.so conc h2so4 cant be used in preparation of h2s gas
What is the rule for mixing acids and water?
Always add acid to water, not water to acid. This helps to prevent the acid from splashing back and causing potential harm, as adding water to acid can lead to an exothermic reaction and potentially dangerous spattering.
Is barium sulfite soluble in water?
0.16 grams of BaF2 only soluble in 1 litre of water. But it can be dissolved using Nitric acid and Hydrochloric acid. 0.5 g BaF2 + 5 ml Conc. HCl + 5 ml of Conc. Nitric acid - boil it until effervescence ceases. Add some water. You get clear solution.
Why you add talc in conc cinnamon water?
The use of talc greatly increases the surface area of the volatile substance, insuring more rapid saturation of the water
How is the strength of hydrogen peroxide changed?
Water is added to decrease the Conc^ or the water is evaporated of to increase the Conc^
What is reaction of a exothermic?
Mixing of conc. sulfuric acid with water

How could humans apply the squid's method of locomotion in the water to a human-made vehicle targeted to move in the water?

How does osmosis occur in cells?
Osmosis occurs in cells when water moves across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. This movement of water helps to maintain proper balance and hydration within the cell.
How do you make .02 N hydrochloric acid?
dilute 1.7 ml of Conc. HCl to 1000 ml with water
Define Pseudo unimolecular reaction with example?
there is no meaning in pseudo unimolecular reaction. Explanation: molecularity of a reaction is "the no. of species(ions, molecules or atoms) which collide simultaneously to give rise a chemical change or chemical reaction. a reaction can be called unimolecular (decomposition of ammonium nitrite to nitrogen and water) as single molecule decomposes to give rise to products a reaction can be called bimolecular (HI decomposes to H2 and I2) as two HI molecules are colliding. that means molecularity says about "actually how many species collide and there is nothing ambiguity (pseudo) in it. but a reaction can be called pseudo first order reaction (hydrolysis of sucrose) as rate of reaction depends on only sucrose conc. and water solvent conc. as is in excess do not affect the rate. if any one is having doubts in chemistry u can mail me at chemistry_krish@yahoomail.com
Find equilibrium constant of the reaction?
eqb constant k For a general EQN A+B=S+T the equilibrium constant can be defined by[1] k={S}{T}/{A}{B} {S} = MOLAR CONC. OF S{T} = MOLAR CONC. OF T{A} = MOLAR CONC. OF A{B} = MOLAR CONC. OF B
What is conc of water?
The concentration of water is typically measured in terms of its molarity, which is equal to 55.5 mol/L at room temperature. In other terms, water makes up approximately 55.5 moles in a liter of pure water.
What solution can make gold sparkle again but reduces its weight?
Aqua regia or royal water (mixture of conc. HCl and conc. HNO3 in the ratio of 3:1 by volume) 3HCl + HNO3 = NoCl+2 H2O + Cl . NoCl= nitrosyl chloride Cl= nascent chlorine
What ch3ch2oh gives CH3CHO?
The reaction between ethanol (CH3CH2OH) and an oxidizing agent yields acetaldehyde (CH3CHO). This process involves the loss of hydrogen atoms, resulting in the conversion of the alcohol functional group (-OH) to an aldehyde functional group (-CHO).
What does 2x concentration mean?
double conc.
