I believe the correct answer to your question is Brittle. Hope I'm correct let me know.
The nitrogenous bases on the two strands of DNA pair up, purine with pyrimidine (A with T, G with C), and are held together by weak hydrogen bonds. Watson and Crick discovered that DNA had two sides, or strands, and that these strands were twisted together like a twisted ladder -- the double helix.Mar
5.911 grams of manganese dioxide and 1.224 gram of water are consumed.
<h3>What is Balanced Chemical Equation ?</h3>
The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.
The given reaction balanced equation is:
Zn(s) + MnO₂(s) + H₂O(l) → ZnO(s) + Mn(OH)₂(s)
<h3>How to find the number of moles ?</h3>
To find the number of moles use the expression:
Number of moles = 
Here,
Mass of Zn = 4.50 g
Molar mass of Zn = 65.4 g/mol
Now put the value in above expression
Number of moles of Zn = 
= 
= 0.068 mol
Mass of MnO₂ = Moles of MnO₂ × Molar mass of MnO₂
= 0.068 mol × 86.9368 g/mol
= 5.911 g
Mass of H₂O = Moles of H₂O × Molar mass of H₂O
= 0.068 mol × 18.0 g/mol
= 1.224 g
Thus from the above conclusion we can say that 5.911 grams of manganese dioxide and 1.224 gram of water are consumed.

Answer:
Area is 0.08504
and
are needed for polishing
Explanation:
(a) ft is unit of F.P.S system whether mm is unit of M.K.S system.
According to unit conversion, 
So, 
hence, 
So, area of telescope lens is 0.08504
(b)
are polished in 45s
So,
are polished in
or 
Answer:
A. internal arrangement of atoms
Explanation:
An atom can be defined as the smallest unit comprising of matter that forms all chemical elements. Thus, atoms are basically the building blocks of matters and as such defines the structure of a chemical element.
Generally, these atoms are typically made up of three distinct particles and these are protons, neutrons and electrons.
Hence, all the physical properties of a mineral result from the mineral's internal arrangement of atoms.
