the correct answer is feels slippery
Answer:
<h3>The answer is option D</h3>
Explanation:
To find the speed given the kinetic energy and mass we use the formula
where
m is the mass
v is the speed
From the question
KE = 15 J
m = 2.3 kg
We have
We have the final answer as
<h3>3.6 m/s</h3>
Hope this helps you
MB₂H₆: 2×11g+6×1g= 28 g/mol
...................
B₂H₆ + 3O₂ ---> 2HBO₂ + 2H₂O
28g.......................................2 mol......
28g B₂H₆ ---- 2 mol H₂O
19,2g B₂H₆ --- X
X = (2×19,2)/28
X = 1,37 mol H₂O

essential for a chain reaction in order to sustain itself shows that atomic
mass needs to be heavier for it to release more than one neutron. Because of
this reaction it is expected to release some energy.</span>
