Answer:
Iodine is a mineral found in some foods. The body must have iodine to make thyroid hormones. The hormones control the body's metabolism and many other important functions. Without iodine, thyroid hormone production can decrease.
Explanation:
Hydrogen sulfide = hidrogen + sulfur
6.500 g
a) 0.384 g + x
=> 6.500 = 0.384 + x => x = 6.500 - 0.384 = 6.116 g
Answer: 6.116 g of sulfur must be obtained
b) this experiment demonstrate the conservation of mass.
c) Dalton's atomic model states that the atoms cannot be created, split or be destroyed, and so in a chemical reaction the atoms rearrange but the number of each type of atoms remain constant, so the mass of each type of atoms and the total mass remain constant.
When your substance either; change color, start to smell, explode, form bubbles, precipitate, and/or get hotter or colder.
Answer:
Between carbon and silicon, silicon element has the strongest attraction between its nucleus and its valence electrons.
because silicon's nucleus is bigger than carbon.silicon loses electrons easily than carbon.
Answer:
1.3 × 10³ g
Explanation:
Step 1: Convert the mass of calaverite to grams
We will use the relationship 1 kg = 1,000 g.
Step 2: Establish the appropriate mass ratio
The mass ratio of AuTe₂ to Au is 452.17:196.97.
Step 3: Calculate the maximum mass of pure gold that can be obtained from 3.0 × 10³ g of calaverite
