Someone added the answer already hope that helps you out
Technetium, with atomic number denoted Z43, is the lowest-numbered element in the periodic table of which all isotopes are radioactive
Rust does not have the properties to catch onto flames. However, if you light it on fire, then it would probably catch in flames but not instantly and will not continue to burn unless you have soaked it in oil or flammable object or substance. :) Hope this helps!
Answer:
C
Explanation:
because it remains the same
Explanation:
(6.1). The reaction equation will be as follows.

Assuming the value of
as
and let the solubility of each specie involved in this reaction is "s". The expression for
will be as follows.
(Solids are nor considered)
=
s = 
= 
= 
Therefore, solubility of barium sulfate in water is
.
(6.2). As the molar mass of
is 233.38 g/mol
Therefore, the solubility is g/L will be calculated as follows.

= 
Therefore, solubility of barium sulfate in grams per liter is
.
