Answer:
295.372
It should be right because Room Temperature is 72F
Answer:
The answer is
<h2>2.64 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 611 g
volume = final volume of water - initial volume of water
volume = 256.7 - 25.1 = 231.6 mL
The density of the metal is
We have the final answer as
<h3>2.64 g/mL</h3>
Hope this helps you
Answer:
n = 0.01302 moles
Explanation:
Pressure = 1.3 atm
Temperature = 31 °C + 273 = 304 K ( Converting to kelvin temperature)
Number of moles = ?
Volume = 250 mL = 0.250 L
These quantities are related by the equation below;
PV = nRT
n = PV / RT
n = (1.3 * 0.250) / (0.0821 * 304)
n = 0.01302 moles
1) Conversion of an isotope one chemical element or an isotope into another chemical element is called as nuclear transmutation.
<span>
2) In a nuclear transmutation reactions</span> can be achieved either due to radioactive decay or due to nuclear reactions.
3) In this technique, it is possible to convert a stable element into radioactive atom by bombarding in with high speed particles. The initial stable nuclei is referred as parent nuclei, the fast moving particle is referred as projectile while new element which is formed is called as daughter element.
4) In the present reaction:
<span>1 1 H+ 1 0 n -> 2 1 H
1 1H is a parent nuclei which is bombarded with the fast moving projectile
(1 0 n) to generate a new daughter nuclei (2 1H). </span>
I think the answer is B. Correct me if i'm wrong :)
