Answer: The density of glycerol will be
Explanation:
Density is defined as the mass contained per unit volume.
Given : Mass of glycerol= g
Volume of bromine = 3.25 L=
Putting in the values we get:
Thus density of glycerol will be
The density of glycerol used in cosmetics and soaps is 1.26 g/cm³.
FURTHER EXPLANATION
Density is the measure of the compactness of a material. It is the mass per given volume. This can be expressed mathematically as:
(equation 1)
To solve the problem, we first sort the given in the problem:
mass = 4.10 × 10³ g
volume - 3.25 L
The problem is asking for the density in units of g/cm³ which means that we must first convert the volume from liters to cm³.
Now we can plug in the values of mass and volume into equation 1:
Since the given in the problem both have 3 significant figures, the final answer must also have three significant digits only. Therefore,
The density of glycerol is greater than 1, so when mixed with water it will sink.

Answer: The correct answer is Image 3.
Explanation:
Lewis dot structure is defined as the structure which represents the number of valence electrons around the atom. The electrons are represented as dots.
From the structure, we can easily determine the number of bonding and non-bonding electrons. Non-bonding electrons are considered as lone pair of electrons.
Carbon is the 6th element of the periodic table having electronic configuration of
This element has 4 valence electrons.
Chlorine is the 17th element of the periodic table having electronic configuration of
This element has 7 valence electrons.
The lewis dot structure for the compound is given below in the image attached.
Hence, the correct answer is Image 3.
High stability over long time and source need not be replaced
High penetration and high ionization
A good source of beta radiation and has a half-life of 432 years
Answer:
Ionization smoke detectors use americium as a source of alpha particles. Alpha particles from the americium source ionize air molecules. This makes some particles positively charged and some negatively charged. ... Because of this shielding, the smoke detector poses no radiation health risk when they are properly handled.
