Answer:
34 g of NH₃ were produced in the reaction
Explanation:
N₂ (g) + 3H₂ (g) → 2NH₃ (g)
Moles of N₂ → 28 g / 28 g/m = 1 mol
Moles of H₂ → 25g / 2 g/m = 12.5 moles
Clearly, the limiting is the nitrogen.
1 mol of N₂ produced 2 moles of ammonia
So, If I have 1 mol, I'll produce the same amount
2 moles of NH₃ = Mol . Molar mass
2 m . 17 g/m = 34 g
Answer:
When water temperature increases (right), the rate of evaporation also increases. In turn, the amount of water vapor in the "air space" above the water increases. ... But, with increased evaporation, more water molecules exist in the air above the water, which in turn increases the condensation rate.
It can be shown that matter is neither created nor destroyed in a chemical reaction by taking a critical look at the each atom in both sides of the reaction (reactant and product sides).
1 atom of Mg started the reaction and 1 atom is also present in the products.
8 atoms of O are present in the reactants and 8 is also present in the products.
4 H atoms are present in the reactants and 4 are also present in the products.
2 N atoms are present in the reactants and 2 are also in the products.
In other words, the total number of each atom that is present in the reactants are also present in the product. Nothing has been lost during the reaction, although, the forms of each atom might have changed.

Answer:
The two elements are POLONIUM and RADIUM.
Explanation:
Maria Curie is a French physicist and chemist, though she was of a Polish naturals. She was the first woman to receive a Noble Price which she earned for conducting leading and head way research on radioactivity. She discovered the theory of radioactivity; also the techniques isolating radioactive isotopes. These helped her and her husband discover Polium and Radium.
