<u>Answer:</u> Silver has 47 electrons, 47 protons and 43 neutrons. Barium has 56 electrons, 56 protons and 76 neutrons.
<u>Explanation:</u>
Atomic number is defined as the number of protons or electrons that are present in a neutral atom.
Atomic number = number of protons = number of electrons
Mass number is defined as the sum of number of protons and neutrons that are present in an atom.
Mass number = Number of protons + Number of neutrons
Atomic number = 47
Mass number = 90
Atomic number = Number of protons = Number of electrons = 47
Number of neutrons = Mass number - Atomic number = 90 - 47 = 43
Hence, silver has 47 electrons, 47 protons and 43 neutrons.
Atomic number = 56
Mass number = 132
Atomic number = Number of protons = Number of electrons = 56
Number of neutrons = Mass number - Atomic number = 132 - 56 = 76
Hence, barium has 56 electrons, 56 protons and 76 neutrons.
Technically speaking, yes you can. Using a microscope though.
Answer:
the answer is Fungi
Explanation:
it makes its own food and doesn't move from place to place that why this is the answer
Filter flasks are
also known as vacuum, suction or the Buchner flasks. They have thick walls and also
have a short glass tube. The thick walls are designed to enable the filter withstand
high pressures of vacuum applied to filter substances. Generally this is used
for filtering.
While the Erlenmeyer flask
also called as a conical flask, is a titration flask which consists of a
conical body, a flat bottom, and round neck. This is used for used for general
uses such as mixing, titrations, preparation of cultures, for
recrystallization, and for supporting filter funnels.
<span>Lastly, the Volumetric flasks are graduated flasks which having markings
for different volumes. They are calibrated accurately for a specific amount of
liquid that can be contained in it hence this is specially used for storing
precise amounts of liquid. </span>
