Answer:
C) O, C, H, N
Explanation:
Roughly 96% of the mass of the human body is made up of the four elements which are carbon, oxygen, hydrogen and nitrogen.
The elements, oxygen and hydrogen are found predominantly in water, which makes up 60% of body's weight approximately. Element carbon is synonymous with life. The central role of the element, carbon is due to the fact that the carbon has 4 bonding sites which allow the element for the building of long and the complex chains of molecules. Nitrogen is found in the organic molecules, including the amino acids which make up proteins, and nucleic acids which make up DNA.
Answer: Deriving from ancient Chinese myths and folklores, a fox that lives a thousand years turns into a kumiho, like its Japanese and Chinese counterparts. It can freely transform, among other things, into a beautiful woman often set out to seduce boys, and eat their liver or heart (depending on the legend).
Hoped that helped!
Explanation:
Solids have definite shape and distinct boundaries as such the intermolecular forces between them is maximum
The answer is C. A, B, and C would depend on what type of electron it is.
16.94 % Zn
Explanation:
First we need the molar weight of the Zn₃(PO₄)₂:
molar weight of Zn₃(PO₄)₂ = atomic weight of Zn × 3 + atomic weight of P × 2 + atomic weight of O × 4 × 2
molar weight of Zn₃(PO₄)₂ = 65.4 × 3 + 31 × 2 + 16 × 4 × 2 = 386 g/moles
Taking in account weight of 1 mole of Zn₃(PO₄)₂ we devise the following reasoning:
if 386 g of Zn₃(PO₄)₂ contains 65.4 g of Zn
then 100 g of Zn₃(PO₄)₂ contains X g of Zn
X = (100 × 65.4) / 386 = 16.94 % Zn
