If the point of the nail can be approximated as a circle with radius 2.00 x 10-3 m, what is the pressure in megapascals
(MPa) exerted on the wall if a hammer strikes the nail with a
force of 104 N? Use 3.14 for II.

yes yes yes yes yes yes yes yes yes yes yes yes yes yes yes

explanation:

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.

did anyone actually do this? like if anyone has submitted this i rly need .

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z
