What types of mixtures are these? (Homogeneous Mixture Hetergeneous Mixture)
1 answer:
Explanation: A <u>homogeneous mixture</u> is a solid, liquid, or gaseous mixture that has the same proportions of its components throughout any given sample. The components that make them up are evenly distributed and the appearance of the solution is uniform throughout.
A<u> heterogeneous mixture</u> has components whose proportions vary throughout the sample. The components of a heterogeneous mixture are visible and not uniform throughout. A heterogeneous mixture is simply any mixture that is not uniform in composition.
a) Peanuts and almonds mixed together in a bowl : The components(Peanuts and almonds) are visible in a bowl and are not evenly distributed and also not uniform throughout. So this is a 'heterogeneous mixture'.
b) Bucket full of sand and gravel : The components(sand and gravel) are visible in a bucket and are not evenly distributed and also not uniform throughout. So this is a 'heterogeneous mixture'.
c) Cup of tea and sugar : The components(tea and sugar) are evenly distributed and the appearance of the solution is uniform throughout. So this is a 'Homogeneous mixture'.
d) Food coloring dissolved in water : The components(Food coloring and water) are evenly distributed and the appearance of the solution is uniform throughout. So this is a 'Homogeneous mixture'.

Explanation:
Hello.
In this case, taking into account that HCl has one molecule of hydrogen per mole of compound which weights 36.45 g/mol, we compute the number of molecules of hydrogen in hydrochloric acid by considering the given mass and the Avogadro's number:
Now, from the 180 g of water, we see two hydrogen molecules per molecule of water, thus, by also using the Avogadro's number we compute the molecules of hydrogen in water:
Thus, the total number of molecules turns out:
