Answer:
from the pic:

since molar mass is 118.084 g/mol;


It is an aldehyde with structure ( second pic )
Explanation:
Relation between length of a curve and angle is as follows.
l = 
where, R = radius of curve
= angle in radians
Also, l =
.......... (1)
If curve has a degree of curvature
for standard length s, then
R =
........... (2)
Now, substitute the value of R from equation (2) into equation (1) as follows.
l =
If s = 30 m, then calculate the value of l as follows.
l =
=
= 452 m
thus, we can conclude that the length of the curve is 452 m.
Answer:
Friction and Automobile Tires. ... On dry surfaces you might get as high as 0.9 as a coefficient of friction, but driving them on wet roads would be dangerous since the wet road coefficient might be as low as 0.1

Answer:
This is a single replacement reaction because I replaces Br.
Using p1v1/t1=p2v2/t2
p1=50
p2=225
v1=400ml
v2=?
t1=-20=253k
t2=60=333k
50x400/253=225xv2/333
7.9=0.7xv2
v2=7.9/0.7
v2=11.3ml
