Evidence of Earth’s plate tectonic activity is most obvious after an earthquake. Which explanation best describes this plate tec

tonic movement?
A: Earth’s plates stress one another. However, when an earthquake occurs, plate movement is due to an unbalanced force on the plates.

B: Earth’s plates are moving fast. However, the force of friction slows their movement.

C: The force of gravity causes the floating plates to move up and down. The plate movement sometimes results in earthquakes.

D: Earth’s plates continually place stress on one another. However, the force is balanced during an earthquake.

Plutonium−239 (t1/2 = 2.41 × 104 yr) represents a serious nuclear waste hazard. if seven half-lives are required to reach a tole
dimulka [17.4K]
The half-life of Plutonium−239, t1/2 is 2.41 × 10⁴<span> yrs

time taken to reach tolerable level = seven half-lives
                                                      = 7 x t1/2
                                                      = 7 x </span>2.41 × 10⁴ yrs
                                                      = 168700 yrs
                                                      = 1.687 x 10⁵ yrs

Hence, the period of time that <span>Plutonium-239 must be stored is </span>1.687 x 10⁵ years.

How many grams of NaOH are contained in 500 mL of a 0.80 M sodium hydroxide solution?
4vir4ik [10]

This is molarity: moles of solute/liters of solution. (Not molality)

1. Plug in what we know:

500 mL = 0.5 L

0.80 = moles/0.5

0.80*0.5 = moles

moles = 0.4

2. NaOH is given as 40 g/mole, so calculate the grams:

0.4 * 40 = 16 grams

answer: 16 grams
