If this is a true or false I would say true... Hope this helps?
The symbol of an isotope that atom of its element contains 50 electrons and 70 neutrons is Tin (Sn).
The Isotope may be characterized as one of two or more types of atoms of a chemical element that significantly have the same number of protons but with different numbers of neutrons and therefore different atomic masses.
In a more simple sense, an isotope may be defined as an atom that has the same atomic number but different atomic mass and physical properties.
According to the question,
The number of electrons an atom possesses = 50.
The number of neutrons = 70.
Since, the number of electrons = the number of protons = the atomic mass of an atom = 50.
∴ According to the periodic table, an element having an atomic number of 50 is known as Tin (Sn).
Its atomic mass = the number of protons + the number of neutrons.
= 50 + 70 = 120 amu.
Therefore, the symbol of an isotope that the atom of its element contains 50 electrons and 70 neutrons is Tin (Sn).

Answer:
Explained below.
Explanation:
Formula when magnesium reacts with hydrochloric acid is given by;
Mg(s) + 2HCl(aq) = MgCl2(aq) + H2(g)
So, from the equation, we can see that the gas formed is hydrogen.
This hydrogen gas is collected by a method known as water displacement.
This gas can be tested for by holding a burning splint near to the top of the test container. The resulting effect should be a high pitched pop sound because the hydrogen gas will react with the oxygen gas in the air to result in a small explosion.
Answer : The structural formula of 2-pentyne is shown below.
Explanation :
Structural formula : In the structural formula, the bonding and type of bonds which holds the atoms in molecule together are shown.
The given name of compound is, 2-pentyne.
A suffix '-yne' present at the end of the name represent the alkyne group.
For the number of carbon atom, we use prefix as 'meth' for 1, 'eth' for 2, 'prop' for 3, 'but' for 4, 'pent' for 5, 'hex' for 6, 'sept' for 7, 'oct' for 8, 'nona' for 9 and 'deca' for 10.
In this compound, the parent chain is 5 membered and a triple bond is present at 2nd position of the parent chain.
Thus, the structural formula of 2-pentyne is shown below.
b.It is a heterogeneous catalyst, so only a small amount is needed and it is easily separated from the products.
c.It is a homogeneous catalyst, so although a large amount is needed, it is easily separated from the products.
d.It is a heterogeneous catalyst, so a large amount is needed and it exits with the products.
