a scientist obtains a small block of sodium. Sodium is a soft silvery metal. She places the block of sodium in a beaker filled with 50mL of water. What are the reactants in this chemical reaction? and explain the evidence int the products for the chemical reaction?

answer: question1

1,000 tons

question2

3: 8

question 3

store d

step-by-step explanation:

12000j is work done

d₁ = displacement of tern from arctic to antarctic = 11000 miles

d₂ = displacement of tern from antarctic to arctic =   - 11000 miles

d = total displacement for the journey

total displacement for the journey is given as

d = d₁ + d₂

d = 11000 + (-11000)

d = 0 miles

t₁ = time of travel from arctic to antarctic = 3 months = 3 x 30 days = 90 days

t₂ = time of travel from antarctic to arctic = 3 months = 3 x 30 days = 90 days

t = total time of travel

total time of travel is given as

t = t₁ + t₂

t = 90 + 90

t = 180 days

average velocity is given as

average velocity = total displacement/ total time

v = d/t

v = 0/180

v = 0 miles/day
