Answer: similarities
- there are some cases where the element confer some of its own properties to the compound, so there are properties which are similar between the element and the compound, for example when an element is strongly charged with electrons, the element confer this property to the compound, and this similar between them.
- the other similarity is that both, the compound and element are formed of atoms, electrons and neutrons.
differences
The principal difference is that a element is conformed only by one element but a compound can be conformed for more than two elements.

S = Sulfur
O = Oxygen
3 = "Tri" prefix
Sulfur Trioxide
Animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are mostly round and irregular in shape while plant cells have fixed, rectangular shapes.
I think b, if the spaceship is outerspace lol.
Answer:
Explanation:
You must convert the 6.00 grams of H₂ into number of moles, and then use the stoichiometry of the reaction to find the number of moles of NH₃, which can be converted into volume using the ideal gas equation.
<u></u>
<u>1. Number of moles of H</u><u>₂</u>
- number of moles = mass in grams / molar mass
- molar mass of H₂ = 2.016g/mol
- number of moles = 6.00grams / 2.016g/mol = 2.97619mol
<u></u>
<u>2. Number of moles of NH</u><u>₃</u>
<u></u>
i) Chemical equation:
ii) Mole ratio:
iii) Proportion:
- x mol NH₃ / 2.97619mol H₂ = 3 mol NH₃ / 2 mol H₂
<u>3. Volume of NH₃</u>
- V = 4.4642857mol × 0.08206 atm·liter/(K·mol) × 506K / 2.05atm
