Answer:

The correct answer would be - observing with the help of five senses.

Explanation:

To find and describe the physical properties of the given substance or the solution or liquid students can observe using their five senses. By looking at the liquid one can find its state and color, by smelling students can find the odor of the sample, by touching it one can observe and describe the texture.

Fluidity can also be measure by the touch if the solution is viscous or free-floating. By using a thermometer and using a graduated cylinder one can find the temperature at room temperature and the weight of substance respectively.

You determine that a sample of a compound contains 1. 4 mol c and 2. 1 mol h. What is the empirical formula for this compound?.
vlada-n [284]

The empirical formula of the compound is C4H1.

An empirical formula represents the whole number ratio of various atoms present in a compound.

If the mass percent of various elements present in a compound is known, its empirical formula can be determined

We are given that a compound contains 4 mole C and 1 mole H.

Hence, the ratio of C: H is 4:1, which is already in the form of the simplest whole number.

Therefore, the empirical formula of the given compound is C4H1 and its molecular mass is 12 x 4 + 1 = 49.

describe how 250 cm³ of 0.2 mol/dm³ H2SO4 could be prepared from 150 cm³ of 1.0mol/dm³ stock solution of the acid​
Reptile [31]

Answer:

Explanation:

250 cm^3 of 0.2 moldm-3 H2SO4 can be prepared from 150cm^3 of 1.0 moldm^-3 by dilution.

150cm^3 of the 1.0 moldm^-3 stock solution is measured out using a measuring cylinder and transferred into a 250 cm^3 standard volumetric flask and made up to mark. The resulting solution is now 250cm^3 of 0.2 moldm-3 H2SO4.

Ordered: 0.3 gm. Available: 300 mg/tablet. How many tablets should be given?
dimulka [17.4K]

Answer:

1 tablet

Explanation:

Assuming that gm stands for gram:

Put everything in one unit, 0.3 g = 300 mg.

And given that each tablet is 300 mg:

mass/amount = 300mg / 1 tablet

300mg / X amount = 300mg / 1 tablet

(300mg/300mg) tablet = X = 1 tablet

So it is 1 tablet you need.
