There are 0.0214 mol Cs in 1.29×10²² atoms Cs.
Use <em>Avogadro’s number</em> to convert atoms of Cs to moles of Cs.
Moles of Cs = 1.29×10²² atoms Cs × (1 mol Cs /6.022 × 10²³ atoms Cs) = 0.0214 mol Cs
This is considered a physical change because the water does not change its chemical properties - it is still water. It is simply just moving its shape such as gas form, liquid form, or solid form.
Answer:
Chemical reaction, a process in which one or more substances, the reactants, are converted to one or more different substances, the products.
Answer:
The air particles are sped up and they are more spaced apart.
Explanation:
This is because when things are heated up the particles speed up and flow more freely causing them to be space apart.
