Physical property of matter found between comparing mass to volume or basically dividing mass by volume is density.
Answer:
91.33 L
Explanation:
For an ideal gas, the product between the gas pressure and the gas volume is proportional to the absolute temperature of the gas. Mathematically:
where:
p is the pressure of the gas
V is the volume of the gas
T is the absolute temperature of the gas
For a transformation of the gas, we can write:
For the sample of krypton in this problem, we have:
(initial pressure)
(initial volume)
(initial temperature)
(final pressure, at stp)
(temperature at stp)
Therefore, the volume at stp is:
Sodium bicarbonate (or baking soda) will cause both exothermic and endothermic reactions when added to water. It becomes either unstable or stable carbonic acid, which will eventually become CO2. The reaction would be exothermic is when H2CO3 (Carbonic Acid unstable) is formed and endothermic is when CO2 is.
False- Strontium will need to lose two valence electrons to make its second-highest energy level be its valence energy level (being filled with an octet of electrons) and possess a more stable electronic arrangement. In order to do so, a single oxygen atom must be available, as both strontium valence electrons will be gained by the single oxygen atom.
Answer:
<h2>53,775 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
m is the mass
v is the velocity
From the question we have
We have the final answer as
<h3>53,775 J</h3>
