Answer:
yo, would this be addition, multiplication, division, or subtraction?
Explanation:
Answer:
Ionic bond occurs between two atoms that have different:
a) Electron
Explanation:
according to the definition of ionic bond,
it is the electrostatic force of attraction that holds the two oppositely charged ions together and an ionic bond or electrovalent bond is formed when one atom gains electrons while the other atom loses electrons from its outermost level or orbit.
Answer:
#atoms C-12 = 3.01 x 10²³
Explanation:
Convert grams to moles and multiply by Avogadro's Number.
6 g C-12 = (6g/12g·mol⁻¹) = 0.50 mol C-12
No. C-12 atoms in 0.50 mol C-12 = 0.50 mol C-12 x 6.02E23 atoms/mole = 3.01E23
2.66 molecules of ammonia are produced
Explanation:
We have bellow the chemical reaction between nitrogen (N₂) and hydrogen (H₂) which produce ammonia (NH₃):
N₂ + 3 H₂ → 2 NH₃
From the chemical reaction we see that 1 molecule of nitrogen reacts with 3 molecules of hydrogen, so 4 molecules of nitrogen will react with 12 molecules of hydrogen but we only have 4 molecules of hydrogen available, so the limiting reactant will the hydrogen. Knowing this we devise the following reasoning:
if 3 molecules of hydrogen produces 2 molecules of ammonia
then 4 molecules of hydrogen produces X molecules of ammonia
X = (4 × 2) / 3 = 2.66 molecules of ammonia
However it does not make sense to produce half a molecule of something (you can not do this in the real world), the problem will make sense if you talk about the number of moles of each substance, because in 1 mole of substance you have 6.022 × 10²³ molecules.
You may find in the attached picture the drawing of the molecules.

Answer:
125 = 5*4.186*m
m = 125 / 5*4.186 = 5.97g of water.
Explanation:
The water is increased by 5 degrees. This means that for every gram of water, it takes 5*4.186 J to increase the temperature by 5 degrees, aka 5*4.186 J/g
hope this help:)
