<span>In an equation, the symbol that would indicate a mixture is c (aq). The meanings of the symbols are: (s) - solid, (l) - liquid, (g) gas, and (aq) - aqueous. Symbol (aq) means that something is dissolved in the water. It represents an aqueous solution. </span>
The movement of gas through a tiny hole is called Effusion. Effusion occurs when there is a barrier with one or many small holes that prevent the gas to expand into the new volume unless a gas molecule happens to travel through the hole. The difference between Effusion and Diffusion is the barrier between the two volumes.
Answer:
exothermic
Explanation:
Disposable hand warmers turn up the heat in your mittens by means of an exothermic reaction that, in essence, just creates rust.
Explanation:
Natural transmutation is the spontaneous disintegration of a heavy nuclide into lighter ones or fusion of lighter nuclides into heavier ones. These processes occurs naturally without anything inducing them. Nuclear fission of light elements in the core of stars is an example of natural transmutation.
- Typically, all nuclei with atomic number greater than 83 are naturally radioactive.
²³⁸₉₂U → ²³⁴₉₂Th + ⁴₂He
In artificial transmutation, nuclear reactions are initiated through the collision of a nuclide with a high speed particle. Here, unstable nuclei are produced artificially in nuclear reactions. Such unstable nuclei also produce radiations.
¹₀n + ²³₁₁Na → ²⁴₁₁Na + γ
