Answer:
Step-by-step explanation:
1) ∠1 + ∠2 = 180 {linear pair}
105 +∠2 = 180
∠2 = 180 - 105
∠2 = 75°
Reason: Linear pair
2) ∠3 = ∠1 {Vertically opposite angles are congruent}
∠3 = 105
Reason: Vertically opposite angles are congruent
Answer:
$ 65.59 more per week
Step-by-step explanation:
Assuming she worked <u>52</u> weeks a year as a clerk :
30534 - <u> 52</u> * 521.6 = $ 3410.80 more per year
now each WEEK that is 3410.80 / 52 = 65.59
The answer is 8 because 12 plus 4 is 16, and then 16 minus 8 is 8

Answer: 36 moles oxygen
Step-by-step explanation:
C10H8 + 12O2 ====》 10CO2 + 4H2O
From the equation of the reaction,
1 mole of napth requires 12 moles of O2
3 moles of napth would require x moles O2
X = (3 * 12) / 1
X = 36 moles of oxygen.
Therefore 3 moles of naphtalene (C10H8) would require 36 moles of oxygen
