In a homogeneous mixture, the ingredient substances are?

Biology
1 answer:
ankoles [38]4 years ago
5 0
A homogeneous mixture is uniform, meaning... Neat and spread evenly throughout. The substances are fairly spread out throughout the mixture. An example my teacher used was Kool-Aid. You mix it and spread the mixture out evenly throughout the drink. A heterogeneous mixture is messy... Like a fruit salad. It's not orderly. The fruit and leaves in it are spread messily.
Also, a mixture (as you probably already know) can be separated without a means of using chemicals. You can separate things like a salads parts. Unlike, oxygen for example, which would be a compound, because you can't separate the elements within it (which I believe is hydrogen and carbon dioxide)

16. What explanation can be used to describe the test tube shown?
elixir [45]

Answer:

Water is polar and oil is nonpolar so the substances won't mix.

Explanation:

Water is polar covalently bonded within the molecule. This unequal sharing of the electrons results in a slightly positive and a slightly negative side of the molecule. oils are nonpolar, so they will remain separate from molecules of a polar solvent such as water.

What is the volume of 2.7 moles of N2 at STP?​
AnnyKZ [126]

Answer:

60.48L

Explanation:

By definition, at STP (Standard Temperature and Pressure), any gas takes up a volume of 22.4L.

Consequently, because the ideal gas law (PV=nRT) states that the number of moles is directly proportional to the volume of the gas, 2.7M of N2 takes up a volume of:

2.7*22.4L

=60.48L
