Why did 50cm3 of soil and add 50cm3 of water not give total of 100cm3?
When soil particles are mixed with water, the soil particles occupy some volume, reducing the total volume of the mixture. This is known as the phenomenon of volume reduction due to the presence of solid particles in a liquid. Therefore, mixing 50cm3 of soil with 50cm3 of water will not result in a total volume of 100cm3 because the soil particles displace some of the water volume.
How do you made nickel sulphate?
1. Tie hair up, put lab coat on and put goggles on. 2. Get a 50cm3 beaker and measure 25cm3 of sulphuric acid 3. Measure 3 grams of the nickel carbonate on the weighing scale and add it to the sulphuric acid. 4. Stir continuously with a glass rod until the reaction is complete and no color change is occurring. 5. Get a conical flask with a funnel and filter paper and filter the solution which was made. 6. When filtration is complete add solution to a beaker and heat under the safety flame of a Bunsen burner 7. After 2/3 of the solution has evaporated stop the Bunsen burner and leave solution. 8. Wait a week and crystals are formed with the name nickel sulphate.
What are the procedures for extracting iron from spinach titration?
1. wiegh approximately 15g of spinach 2. using scissors, cut the leaves into small pieces and place in a 250cm3 beacker ( if frozen simply place in beacker) 3. using a measuring cylinder, add 50cm3 1.0 moldm-3 sulphuric acid ( CARE irritant) and boil the mixutre gently for 5 mins 4. allow mixture to cool then filter it, using a buchner funnel and vacuum filtration . wash the residue in the funnel one with a little distilled water to collect all the filtrate 5. pour all the filtrate and washing s into a 100cm3 volumetric flask. make up to 100cm3 with 1.0moldm-3 sulphuric acid. stopper the flask and shake it well. 6. fill the burette with potassium manganate (VII) solution (CARE stains cloths) 7. using a pippette transfer 10cm3 of the spinach extract solution to the 250cm3 conical flask and add 50cm3 of 1.0 moldm03 potassium manganate (VII) solution from the burrette until pink colour persists for 30 seconds. lol i hope that helps lol
Why add 50cm3 of water and 50cm3 of alcohol it would not add up to 100cm3 of liquid?
If we take 50 ml of two different liquids and mix them they will not always add up to 100 ml. The mixture will be 100 ml only when the chosen liquids don't mix with each other at all, somewhat as in case of oil and water mix.Alcohol does mix well with the water and therefore the final mixture will have a volume less than 100 ml. At molecular level this happens because molecules of alcohol can fit well between water molecules (compared to molecules of oil between water), thus occupying less overall space, resulting in a smaller volume.

Which apparatus would be useful for collecting 50cm3 of gas?
A gas syringe would be useful for collecting 50cm3 of gas as it allows for accurate measurement and collection of gases in a controlled manner.
A metal cylinder has a volume of 50cm3 what is the volume of the displaced water?
The volume of displaced water for a metal cylinder with a volume of 50cm3 is: 13,210 US gallons of water or 11,000 UK gallons of water.
What is the capacity of a rats stomach?
Very small. No more than 50cm3. It depends on the rat.
What is the density of an object that has a mass of 184g and a volume of 50cm3?
Density= Mass/Volume = .183kg/50cm3= .00366 kg / m^3 the above solution is wrong because you have to get the units right density = mass/volume = kg/m^3 = 1000g/1000000cm^3 density = 0.183/0.00005 = 3660Kg/m^3
Can a 45cm3block fit in a 50cm3 space?
The cubed root of 45 is 3.5568... and the cubed root of 50 is 3.6840... Therefore, yes
A brick has a volume of 50 cm3 and a mass of 150g What is its density?
Density = Mass/Volume = 150g / 50cm3 = 150/50 g per cm3 = 3 g per cm3
What is the density of a cube with a mass of 200g and a volume of 50cm3?
Density = mass/volume , so 200/50 = 4 g / cubic cm.
How many ml of ethyl alcohol in 50ml rubbing alcohol?
It is prepared from a special denatured alcohol solution and contains approximately 70 percent by volume of pure, concentrated ethanol (ethyl alcohol) or isopropanol (isopropyl alcohol), so approximately 35 mL in a 50mL bottle.
What is the density of an object that has a mass of 184 g and a volume of 50cm3?
The density as defined as the mass per unit volume. Accordingly, the density equals 184/50 = 3.68 g/cm3
What is the density of 50 a volume of 50cm3 and a mass of 200g?
The density of the object is 4 g/cm3. To calculate density, you divide the mass by the volume. In this case, 200g / 50 cm3 = 4 g/cm3.
2008 roketa 50cc scooter what size of motor does it have?
50cc is the size of the engine/motor. 50cc means it is 50 cubic centimetres, that's 50cm3 (that 3 should be smaller and diagonally above the m to the right).
