Answer:
99 L
Explanation:
Step 1: Given data
Moles of nitrogen: 4.4 moles
Step 2: Calculate the volume occupied by 4.4 moles of nitrogen
The volume occupied by a gas depends on other conditions such as pressure (P) and temperature (T). If we have this information, we can calculate the volume of the gas using the ideal gas condition.
P × V = n × R × T
Since the task doesn't inform the conditions, we can assume it is under standard pressure (1 atm) and temperature (273.15 K). At STP, 1 mole of any gas occupies 22.4 L.
4.4 mol × 22.4 L/1 mol = 99 L
Answer:
A
Explanation:
Radon is an alpha emitter. It emits alpha particles giving off gamma ray. It is a radioactive byproduct of radium-222.
Radon also penetrates the skin. This is because radon is a gas and chemically unreactive with most materials, it moves easily through very small spaces, such as those between particles of soil and rock, to the soil surface
Option B is wrong. It is produced during radioactive decay of radium and not uranium.
Option C is wrong. Radon is not a metallic element.
Option D is wrong also. It is not produced from photochemical smog
Option E is wrong. This is an extension of option B. Uranium is generally used in nuclear plant operations and not radium
Answer:
x = 130 Ms⁻¹
Explanation:
The equation is:
x = (2.4 x 10³ M⁻²s⁻¹)(0.38 M)³
The expression raised to the power of 3 is simplified:
x = (2.4 x 10³ M⁻²s⁻¹)(0.054872 M³)
The two values are multiplied together and units canceled:
x = 130 Ms⁻¹
So this isn't a question but thanks for telling me...? Next time ask a question pleaseeeee.
