M1V1 = M2V2
225M1 = (2)(120)
225M1 = 240
M1 = 240/225 = 1.066 M C
Answer:
KOH molar mass = 39 + 16 + 1 = 56g
To make 1 L of 1M soln needs 56g KOH
To make 500mL 1M needs 56/2 = 28g
To make 500mL 0.2M needs 28 x 0.2gn:
Answer:
308.7 mL
Explanation:
V1/T1 =V2/T2 T must be in K units
V2 = V1T2/T1
= (.250)(95 + 273.15) / (25 + 273.15) = .3087 LITER
<h2>Nucleosynthesis.</h2>
Explanation:
A. the Big Bang occurred; the Big Crunch occurred
Nucleosynthesis is the process by which new atomic nucleus are formed from pre-existing protons and neutrons.
According to cosmic theories, the nucleosythesis began one minute after the occurrence of Big bang and will end with the big Crunch.
The Big bang theory describes all the processes by which the universe came into existence while the big crunch theory explains how universe will come to an end. A
Answer:
Black holes are astronomical objects that have such strong gravity, not even light can escape. Neutron stars are dead stars that are incredibly dense. ... Both objects are cosmological monsters, but black holes are considerably more massive than neutron stars.
