Ch4+br2=ch3br+hbr which type of reaction does this equation represent
Neporo4naja [7]
<span>this could be a substitution reaction. as you will locate, between the hydrogen's on the propane chain replaced into substituted for a Br from Br2. that's particularly no longer a addition reaction! addition reactions artwork once you have a AlkENE! by using fact that's an AlkANE it would not have a double bond to act as a nucleophile to attack the Br2 (which might act as a electrophile to boot reactions).</span>

Why can’t an atom lose or gain a proton
Veronika [31]

Explanation:

Atoms never gain protons; they become positively charge only by losing electrons. A positive ion is called a cation (pronounced: CAT-eye-on). You may have notice that the number of neutrons in each of these ions was not specified.

A marble rolls off horizontally from the edge of table top 1.50 m above the floor. it strikes the floor 2.0 m from the base of t
GrogVix [38]

a. t=0.553 s

b. vox(horizontal speed) = 3.62 m/s

<h3>Further explanation</h3>

Given

h = 1.5 m

x = 2 m

Required

a. time

b. vo=initial speed

Solution

Free fall motion

a. h = 1/2 gt²(vertical motion=h=voyt+1/2gt²⇒voy = 0)

\tt t=\sqrt{\dfrac{2h}{g} }

t = √2h/g

t = √2.1.5/9.8

t=0.553 s

b. x=vox.t(horizontal motion)

\tt x=v_{ox}\times t

vox=x/t

vox=2/0.553

vox=3.62 m/s
