Answer:
-OOH
Explanation:
This forms an acid if it comes in contact with a metal
Periodic table is an arrangement of chemical elements in an organized manner with atomic number. Elements are distributed in columns and groups in periodic table according to their properties.
Many elements have their isotopes and mostly are radioactive but isotopes are not mentioned on the periodic table, elements are mentioned there and all trans-uranium elements are most radioactive.
Answer:
on the PH scale anything with a ph of 1-7 is acidic, anything 7-14 is basic, in this case the solution mentioned in the question is basic.
Answer:
compounds
Explanation:
the actual term would be chemical compound
25 moles of C3H8 will be produced from 75 moles of CO2.
<h3>Mole calculation</h3>
To find the value of moles of a product from the number of moles of a reactant, it is necessary to observe the stoichiometric ratio between them:

Analyzing the reaction, it is possible to see that the stoichiometric ratio is 1:3, so we can perform the following expression:
C3H8 CO2


So, 25 moles of C3H8 will be produced from 75 moles of CO2.
