Answer:
They are the smallest units of matter
Explanation:
Atom are the basic units of a chemical element; the smallest unit of an element that retains the properties of an element
Answer:
Weigh less than 61.9 g
Explanation:
The symbol V represents the element Vanadium and He represents Helium.
Generally, 1 mol of any atom contains 6.022 * 10^23 atoms. This means we have to find the number of moles of each elements.
For V;
Number of moles = Mass / Molar mass = 61.9 / 50.94 = 1.215 mol
1 mol = 6.022 * 10^23 atoms
1.215 = x
Number of atoms = 6.022 * 10^23 * 1.215 =7.317 * 10^23
For He;
Since equal number of moles contain equal number of atoms;
Number of mol of He = 1.215 mol
Number of moles = Mass / Molar mass
Mass = Molar mass * Number of moles = 4 * 1.215 = 4.86 g
This means it would weigh less.
Answer:
Liquid volume is usually measured using either a graduated cylinder or a buret. As the name implies, a graduated cylinder is a cylindrical glass or plastic tube sealed at one end, with a calibrated scale etched (or marked) on the outside wall.
Answer is: B) titration.
Equivalence point is the point in which there is stoichiometrically equivalent amounts of acid and base.
Chemist can draw pH curve (graph showing the change in pH of a solution, which is being titrated) for titration and determine equivalence point.
The midpoint of a steep vertical section indicates the equivalence point
