Hello!
The density of water is 1 g/mL.
Explanation:
There isn't enough data in your question, but I'll show you how to calculate the density of water from measurings using a graduated cylinder.
You probably measured the mass of the empty cylinder (Mec), then add a known volume of water (V) and after that, you measured the mass of the cylinder with water (Mwc). From this data, it's easy to calculate the density of water, using this formula:
The value you get should be close to 1 g/mL
Have a nice day!
I can’t see the picture properly...
The answer is (3). The powdered iron and the piece iron is the same substance and is just different in the shape. So the reason is the power has larger surface area for reaction occurs.
Answer:
Almost all corn oil is expeller-pressed
Explanation:
then solvent-extracted using hexane or 2-methylpentane (isohexane). The solvent is evaporated from the corn oil, recovered, and re-used. After extraction, the corn oil is then refined by degumming and/or alkali treatment, both of which remove phosphatides.Oct 16, 2020
Silicon generally forms at least polar covalent bonds, like carbon, as befits its status as a Gropu 4A nonmetal. The only obvious exception I can think of is SiC, which despite the similarity you might expect to graphite or diamond does, I think, have significant ionic or metallic character to its bonding in the solid state.
