A 0.50-quart jar contains 2.0 pounds of honey. 1.9 g/ml is the density of the honey.

Density is a measure of how much "stuff" is in a given space. For example, a block of the heavy element lead (Pb) is denser than the softer, lighter element gold (Au). Styrofoam blocks are less dense than bricks. Defined as mass per unit volume.

The density of an object is one of the most important and easiest physical properties to measure. Density is commonly used to identify pure substances and to characterize and estimate the composition of various types of mixtures. Density is an important concept because it can determine which substances float and which sink when placed in a liquid. In general, matter floats as long as its density is less than that of the liquid.

Why is a solution not a pure substance

Firlakuza [10]

It is not a pure substance, because a solution are mixed chemicals in a way that the molecules are not bonded with one another. Thus, separating them from compounds and elements, which are pure substances.

A gas occupies a volume of 650.0 mL when the pressure is 3.50 atm. What will the new volume be if the pressure is reduced to 1.6

Gemiola [76]

The new volume will be 1379 mL.

Explanation:

As per Boyle's law, the product of initial volume and initial pressure of any gas molecule is equal to the product of final volume and final pressure of those molecules.

So here the initial volume is 650 ml and the initial pressure is 3.50 atm. As the temperature is said to be constant, then this system will be obeying Boyle's law. So, the final pressure is given as 1.65 atm. As there is a reduction in the pressure, the volume of the gas is tend to get expanded.

$P_{1} V_{1} = P_{2} V_{2}$

So, $(650*10^{-3}*3.50)=(1.65*V_{2})$

$V_{2} = \frac{650*10^{-3}*3.50}{1.65} = 1379 mL$

So, the new volume of the gas on reduction in pressure is 1379 mL.

Answer:

atomic #= 1

protons equals one
Number of neutrons equals to 0
number of electrons equal to 1
mass number equals to 1

atomic number equals to 1
Protons equals to 1
number of neutrons equals to 0
number of electrons equals to 0 because the plus sign means that it loses an electron
mass number equals to 1

atomic number 17
number of protons 17
number of neutrons 18
number for electrons 18 Because negative sign means It's an anion which means it gains an electron
mass number 35

12

10 loses 2 its a cation
