Explanation:
The boiling point of petrol is 483K and that of water in 373K. Since the difference between the boiling point temperatures is high, we can use the method of distillation as explained above to obtain petrol and water from the liquid mixture. Therefore, the correct answer is option (A).
Answer:
21.32 L
Explanation:
First, convert grams to moles using molar mass. C has a mass of 12 and O has a mass of 16. CO2 will therefore have a mass of 28 g/mol. Divide 22 by 28 to get about 0.79 moles. Convert C to Kelvin by adding 273; getting 323K. Then use the ideal gas law (PV=nRT) to solve for V (V=nRT/P). This gets you 21.32 L, hope this helps!
Here we have to choose the specific iron ion preset in the compound FeO among the given ions.
The iron ion present in FeO is iron (II) ion.
The compound FeO is a neutral compound. Where the anion is oxide ion (O²⁻) thus the cation should also contain two unit positive charge. Thus Fe²⁺. Hence , the iron ion is Fe (II) ion.
The ferride ion means Fe²⁻ ion which cannot be present in FeO as the anion is already present which is O²⁻.
The iron (I) ion means iron present in +1 state, then to neutralize the compound 2 iron (I) is needed but in compound FeO there is only one iron present. Thus it cannot be iron (I) ion.
The ferride (I) ion means Fe¹⁻, which cannot be the state of the iron in FeO as there already present an anion which is O²⁻ ion.
Answer: Mixtures are the substances composed of two or more forms of matter. You can separate them by physical methods. Such examples include a mixture of salt and water, a mixture of sugar and water, different gases, air, etc.
Explanation:
I would go with D. All of the above.
