Answer:
Intrinsic properties
Explanation:
Neutron affects the mass of an atom and intrinsic properties depend on the mass of the substance
Answer:
a. True
Explanation:
Palmitic acid is the acid found in animals and plants. It is the saturated acid that contains fats. It is extracted from palm oil and from fat sources like butter, cheese, milk and meat. It is added in milk with low fat content to add Vitamin A in it. The fat content of palmitic acid is very high. excessive consumption of palmitic acid leads to heart diseases and life risks.
Answer:
NiO
Explanation:
Firstly, we need to know the mass of oxygen used up. This is the difference between the mass of the nickel and the mass of the oxide. This is : 2.852 - 2.241 = 0.611g
Now we convert these masses to mole by dividing by their atomic masses. The atomic mass of oxygen is 16 while that of nickel is 59
O = 0.611/16 = 0.0381875
Ni = 2.241/59 = 0.037983050847458
The next thing is to divide each by the smaller number of moles, which is that of the nickel.
O = 0381875 /0.037983050847458= 1
Ni= 0.037983050847458/0.037983050847458= 1
The empirical formula is thus NiO
Am - it has an atomic number of 95 which is greater than 92.
Transuranium elements are elements with atomic levels greater than 92
