Answer: C(s) + O2(g) --> CO2(g)12g (C) .... 50.8g (O2)................. initial amounts0g(C) .........18.8g(O2) ................. amounts when reaction completeThat means that C was the limiting reactant, and the amount of CO2 is based on the amount of carbon that burned. Covert 12 grams of carbon to moles. The moles of CO2 will be the same, since they are in a 1:1 mole ratio. Then convert the moles of CO2 to grams.12g C x (1 mol C / 12.0 g C) x (1 mol CO2 / 1 mol C) x (44.0g CO2 / 1 mol CO2) =44 g of CO2
2 days. 20 grams of carbohydrates
Explanation:
Atomic number = number of electrons = 10
Mass number = number of electrons + number of neutrons = 10 + 14 = 24
Answer:
It's a.
Explanation:
That would be Ca2+ , F- . We see in the compound CaF2 the signs balance to give a neutral compound, 2+ balances with 2-.
We can confirm that malachite and pyrite are similar in that they are both carbonate minerals, they differ however in chemical composition and characteristics.
<h3>What is malachite and pyrite?</h3>
Pyrite is a form of iron sulfide. This mineral has come to be known as the fool's gold, for its striking resemblance to gold. Malachite, on the other hand, has been known to closely resemble emeralds and is often used as a gemstone. They are both carbonate minerals, but malachite is copper-based, giving it a different chemical composition and properties.
Therefore, we can confirm that malachite and pyrite are similar in that they are both carbonate minerals, they differ however in chemical composition and characteristics.
