I'm writing this in the structure of an actual pyramid.

Tertiary Consumers -- Top of the food chain
Secondary Consumers
Primary Consumers -- This is the start of heterotrophs.
Producers -- Bottom of the food chain, these are the plants/autotrophs.

When metal atoms combine chemically with atoms of other elements, what do they usually do?

Fiesta28 [93]

Answer:

Maybe I know too much chemistry but how the metals (and the non-metals) react depends on where they are in the Periodic Table. The metals in groups I and II over on the far left side are explosively reactive and loose electrons and form ionic bonds. Examples: Na+1 has lost 1 electron and Li+2 has lost 2 electrons. The metals in the higher groups are more confusing but most of them share outer shell electrons and form covalent bonds. Examples: Fe2O3 (rust) where Iron shares 2X3 electrons with Oxygen which shares 3X2 electrons. Confused enough? :-)

The answer you'll be expected to give depends on the subject of the chapter you're studying. If you're studying covalent bonds, then the answer will probably be "form covalent bonds". If you're studying ionic bonds, then the answer will be "lose electrons".

Which unit conversion allows you to convert 21.0 gallons into milliliters?

Romashka-Z-Leto [24]

79470.2mL

Explanation:

Given:

Volume = 21gallons

problem, convert to milliliters;

gallons to milliliters

1 liter = 1.057 quarts

1 gallon = 4 quarts

we can simply solve this by establishing and using a conversion factor of 1 ;

1 gallon = 4 quarts

1.057 quarts = 1 liter

0.001L = 1mL

21gallons x $\frac{4qt}{1gal} x \frac{1 liter}{1.057qt} x \frac{1mL }{0.001L}$ = 79470.2mL

we say;

From; $\frac{4qt}{1gal} x \frac{1 liter}{1.057qt} x \frac{1mL }{0.001L}$

1gallon = 3784.2mL
