Answer:
Double Displacement reaction
Explanation:
BaCl2 + Na2SO4 → 2NaCl + BaSO4
Double displacement reaction occurs when the cations and anions of the two reacting compound interchange, forming a new products. From the equation given above, Na^+ switch place with Ba^2 + and likewise Cl^- with (SO4) ^2- to form NaCl and BaSO4.
Answer:
See explanation
Explanation:
Number of protons = 28
Number of neutrons = 28
Mass of each proton = 1.007277 amu
Mass of 28 protons = 28 * 1.007277 amu = 28.203756 amu
Mass of each neutron = 1.008665 amu
Mass of 28 neutrons = 28 * 1.008665 amu = 28.24262 amu
mass defect of nickel-56 = 0.4667 amu
Binding energy = Δmc^2
Binding energy = 0.4667 *(3 * 10^8)^2
Binding energy =4.2 * 10^16 J
Binding energy per nucleon = 4.2 * 10^16 J/56
Binding energy per nucleon = 7.5 * 10^14 J
I would say that the organism that is responsible for clean up in this ecosystem are decomposers. They <span>are organisms that break down dead or decaying organisms, and in doing so, they carry out the natural process of decomposition. Hope this answers the question.</span>
Answer:
Valency is the number of bonds an element or an atom can form. Whereas valence electrons are the electrons that take part in chemical bond formation. The formation of bonds between the atoms are explained by valency. Whereas, the elemental character of an atom is explained by the valence electrons.
<span>Properties Shared by Metals and Metalloids:
1) Solid nature.
2) They both can form alloys
</span><span>Properties Shared by Metalloids and Nonmetals
1) Non-metallic nature
2) Both have narrow band gaps in band structure
Hope this helps!</span>
