The reaction 4Al + 3O₂ → 2Al₂O₃ is a synthesis or also called combination reaction because reactants combine to produce a new compound (Option 2).
<h3>What is a synthesis combination reaction?</h3>
In chemistry, a synthesis or combination reaction is any type of chemical reaction in which two or more molecules called reactants combine to produce one or more molecules called products of such reaction.
Therefore, with this data, we can see that a synthesis or combination reaction is a chemical process where two or more molecules combine to produce a new molecule known as a product.

<u>Ques</u><u>tion</u><u>:</u>
Azaria's pet lizard runs a distance of 45 meters in 24 seconds. What is the speed of the lizard?
_________________________________________________
<u>Solu</u><u>tion</u><u>:</u>
We are given,
- Distance = d = 45 m
- Time = t = 24 s
Speed is given by:
Putting the given values,
s = (45 m)/(24 s)
=> s = 1.875 m/s
_________________________________________________
Answer:
zero
Explanation:
Speed is constant so, the acceleration is zero and hence the force is zero. So the work done is defined as he product of force and the distance traveled in the direction of force.
W = F x d
W = 0 x 250
W = 0 J
Thus, the work done is zero.
Answer:
(A)
Explanation:
No, because it is not orbited by another star
Hope this help :)
Answer:
T1 cos 15 = T2 cos 26
T1 = T2 cos 26 / cos 15
T1 = 0.930 T2 ------------(1)
T1 sin 15 + T2 sin 26 = m g
substitute eqn(1)
(0.930 T2 ) sin 15 + T2 sin 26 = 230 * 9.8
0.241 T2 + 0.438 T2 = 2254
Tension in right cable T2 = 3319 N
substitute in eqn (1)
T1 = 0.930 * 3319
Tension in left cable T1 = 3087
