No. helium is an element. A mixture should have more than one substances.
the gas mixture is 32.1 ratio if you put too much it will be too rich and cause plug fouling if you dont put enough it will be too lean and blow the top end so mix it 32.1 ratio with 2 gallons of gas and it should run like a dream
you should try to float because quicksand is a mixture of water and sand.
When the solutes (soluble ingredients) mix together with the solvents (insoluble ingredients) to form a mixture that is of the same consistancy throughout. Eg - When making concrete the cement should be fully mixed, making a homogenous mixture so as to maximise strength. ------------------------ You get a solution.
A mixture like saltwater (Sodium Chloride) is said to be homogeneous because the dissolved particles are not visible. Properties of Sodium Chloride include a greater density then freshwater thus making it easier for objects to float on its interface as well as having a salty flavour.
Water in a swimming pool is compound because the water and chlorine have been chemically combined.
strong and slightly flexible
yes it is an homogeneous mixture because it has only one phase
yes, just not too lean, which means to little oil which can make them seize, i run my rm250 at 32/1 which is around 310 milliliters of oil to 10 liters of petrol. and if you run the mixture too rich,(to much oil) you risk fouling your spark plug. the bottle of oil you buy should have directions on the correct mix
No because you dissolve the yeast in water.
To ensure that you have the more product which will be produced because the equilibrium will shift to produce it. This will produce heat and also more chemical product that you want in the equilibrium mixture.
The answer should be up in yo book guess you shoulda brought it homne.
