Answer:
true
Explanation:
Geologic time is divided into four large segments called Eons: Hadean, Archean, Proterozoic, and Phanerozoic. The Phanerozoic Eon isdivided into Eras: Paleozoic, Mesozoic, and Cenozoic. The divisions among Eras reflect major changes in the fossil record, including the extinction and appearance of new life forms.
Hey there!:
Wavelength λ = 0.650 fm = 0.650* 10⁻¹⁵ m (1 fm = 10⁻¹⁵ m)
Speed v = 129 m/s⁻¹
Planck constant h = 6.626 * 10⁻³⁴ J.s
De Broglie equation: λ = h/mv
Mass m = h/λv
= 6.626 * 10⁻³⁴/ ( 0.650* 10⁻¹⁵ * 129)
= 6.626*10⁻³⁴ / 8.385*10⁻¹⁴
= 7.902*10⁻²¹ Kg
Hope that helps!
Hey there!
<span>In this case, the equation of Clapeyron is used :
R = 0.082
Volume in liters :
100.0 mL / 1000 => 0.1 L
</span>
P * V = n * R * T
15.0 * 0.1 = 0.500 * 0.082 * T
1.5 = 0.041 * T
T = 1.5 / 0.041
T = 36.5 K
Answer C
Answer:
The answer is
<h2>4.5 × 10²²</h2>
Explanation:
To find the number of atoms of titanium , given it's number of moles we use the formula
<h3>N = n × L</h3>
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question
n = 0.075 mol
We have
N = 0.075 × 6.02 × 10²³
We have the final answer as
<h3>4.5 × 10²²</h3>
Hope this helps you
False, metamorphic rocks are formed under pressure, is crystals are then formed into layers
