1.a) All except copper can react with dilute sulphuric acid.
REACTION OF DILUTE SULPHURIC ACID WITH COPPER (II) CARBONATE
CuCO3 (s) + H2S04 (aq)———> CuSO4(aq) +CO2(g)+ H2O (l)
REACTION OF COPPER (II) OXIDE WITH DILUTE SULPHURIC ACID
CuO (s) + H2SO4 (aq)———> CuSO4 (aq) + 2H2O (l)
Answer:
1.25 standard atmosphere = 950 Torr
Explanation:
Formula
multiply the pressure value by 760!!
We can define atomic mass the total of number of protons and number of neutrons in an atom or isotope.
<span>So when an isotope of yttrium has 39 protons and 59 neutrons, its atomic mass is equal to;
number of protons + number of neutrons = 39 + 59 = 98</span>
Would it be lack of water and food?
