Answer:
The element of the atom.
Explanation:
The number of protons confirms what element is the atom.
Clearly volume will INCREASE almost sevenfold, as we would expect if we reduce the pressure. ... Assuming this is an ideal gas, and that the number of molecules *n* of this gas remains constant, and given that the temperature is also ... That is, in these conditions, pressure times volume is constant :
Answer: Theoretical mass of sodium sulphate (
) is 514.118 grams.
Explanation: For a given reaction,

As NaOH is used in excess, therefore it is an excess reagent and
is a limiting reagent as the quantity of the product will depend on it.
We are given 355 grams of
.
Molar mass of
= 98.079 g/mol
Molar mass of
= 142.04 g/mol
1 mole of
is producing 1 mole of
, so
98.079 g/mol of
will produce 142.04 g/mol of
355 grams of
will produce =
of 
Mass of
= 514.118 grams
B) Tellurium is a metalloid. Metalloids in some classifications are also or alternatively called “semi-metals.”
