Answer: mechanical
Explanation:
its a big mechanicale thing
Lithium sulfide (Li2S) would have 2 lithium atoms for every sulfur atom and would form an ionic bond. Sodium oxide (Na2O) has 2 sodium atoms for every oxygen atom (same ratio) and forms an ionic bond.
Answer:
0.010g of C-14 would be later after 50,000 years
Explanation:
The kinetics of radioactive decay follows the equation:
Ln (N / N₀) = -kt
<em>Where N could be taken as mass after time t, </em>
<em>N₀ initial mass = 4.30g;</em>
k is rate constant = ln 2 / t(1/2)
<em>= ln 2 / 5730years = 1.2097x10⁻⁴ years ⁻¹</em>
<em />
Replacing:
Ln (N / 4.30g) = -1.2097x10⁻⁴ years ⁻¹ * 50000 years
N / 4.30 = 2.36x10⁻³
N =
<h3>0.010g of C-14 would be later after 50,000 years</h3>
Answer: 100kPa at constant temperature.
Explanation:boyles law v1/v2 = p2/p1
v1 = 1L, p1 = 150 kPa, v2 = 1.5L
so p2 = p1*v1/v2 = 150*1/1.5 = 100 kPa
