Water has a density of 0.9982 g/mL, so it will sink.
Platinum, Copper, Palladium, Silver
Explanation:
These metals noble metals that are inert and nonreactive to a large extent. This is why they used for a wide range of engineering works.
- They are classified as platinum group metals.
- These metals are a group of minerals that are inert and nonreactive.
- They have huge economic values.

Answer: only Br2.
Justification.
In a chemical reaction the element that gains electrons experiments a reduction in its oxidation state, that is why it is said that it is reduced.
So, to know what element is being reduced you need to calculate the oxidation states of the elements involved.
Here I indicate the oxidation states of each element if the reaction putting them inside parenthesis:
Reactants side Products side
K (0) K (1+)
Br (0) Br(1-)
So, K lost one electron, increasing its oxidation statefrom 0 to 1+, meaning that it is being oxidized.
And, each atom of Br gained one electron, reducing its oxidation state from 0 to 1-, meaning it is being reduced.
Therefore, the answer is that Br2 is the substance being reduced.
The hydrogen and oxygen<span> atoms from H</span>₂O are <span>bonded together through covalent </span>bonding.
C2H2 is the right answer I believe
