Answer: Option (d) is the correct answer.
Explanation:
Metals are the species which contain more number of electrons.
When a specie loses electrons then it acquires a positive charge. Whereas when an atom gains electrons then it acquires a negative charge.
Thus, as metals have more number of electrons, therefore, in order to gain stability metals readily lose electrons.
Hence, metals naturally form positive ions, by losing electrons to empty the valence shell.
There are 12 hydrogen atoms :)
Answer:
Either the first one or the third one.
Explanation:
Using process of elimination: knowing that the controlled variable is something the conductor is able to control and stays the same throughout; the amount of water is the same, but it also states that temperature is not the same throughout. This cancels out B because the amount of sugar dissolved varies and doesn’t stay the same. D fits the same criteria as well.
so now we are left with A and C.
An independent variable is something that can be by itself and doesn’t depend on anything else. Sugar is NOT independent, as it dissolves DEPENDING on the amount of liquid. So we can already rule out that sugar is a dependent variable. Both A and C have those choices though, so now we are with the control group and the independent variable.
Think about it, which is the independent variable? Water amount doesn’t depend on anything, while the temperature depends on the room. So the answer is most likely A.
Hope this helps, don’t stress about homework. Happy Holidays!
It means any of a class of salts derived from certain organic ethers or alcohols by adding a proton to the oxygen atom and thusproducing a positive ion(oxonium ion)
