I believe you mean NaCI*, (sodium chloride) . Sodium Chloride is not an element, it is known as an ionic compound, reason being because it forms an ionic bond with Na and CI.

Answer:
So ²³⁵UF₆ effuses 1.0043 times faster than ²³⁸UF₆
Explanation:
The rate of effusion of two gases A and B can be expressed by <em>Graham's law</em>:

Where M is the molar mass, and in this case A is ²³⁵UF₆ while B is ²³⁸UF₆.
So now we <u>calculate the molar mass of each mass</u>:
²³⁵UF₆ ⇒235 + 6*19 = 349 g/mol
²³⁸UF₆ ⇒238 + 6*19 = 352 g/mol
Putting the data in Graham's law:
= 1.0043
So ²³⁵UF₆ effuses 1.0043 times faster than ²³⁸UF₆.
Answer:
Coal is the fossil fuel causing the most pollution.
Explanation:
I hope this helps.
This is the pattern formed in a fluid when heating causes part of the fluid to rise and then cooling causes it to sink again. Within Earth's mantle they circulate heat and drive plate tectonic processes. Within the atmosphere and oceans, they drive winds and weather patterns:Convection Cell
