What is the difference between the soluble and insoluble substances​
Harrizon [31]

Soluble means that something will "dissolve" in a substance (typically water). This means that the substance is polar (like water)

insoluble is the opposite of soluble. It means that a substance will not dissolve in water. This means this is non-polar

Hope this helped!

Some one help me please I'm stuck Show using two conversion factors how you would convert from 0.020 kg into mg.
julia-pushkina [17]

Answer:

=2.0x10^4mg

Explanation:

Hello there!

In this case, when performing units conversions involving two proportional factors we need to make sure we first convert to the base unit and then to the target one; thus, since 1 kg = 1000 g and 1 g = 1000 mg, we set up the following expression:

=0.020kg*\frac{1000g}{1kg} *\frac{1000mg}{1g} \\\\=2.0x10^4mg

Best regards!

The relationship between a law and a theory is
irinina [24]
I would say it’s ‘laws are based on complex theories’.

A scientific law predicts the outcome, while a theory presents a possible explanation to why this outcome is. A law is based of a theory that supports the most data.
