Answer: The aluminum atom loses electrons to form an ion.
The ion that is formed is <u>positive</u>
<u></u>
<u>Second Part of the question:</u> What is the name of the aluminum ion?
<u>
</u>Answer : <u>Al+3</u>
Explanation: <em>An aluminum ion has a charge of +3. It is not a neutral atom. It has a + charge, the electrons must have been taken away (electrons have a negative charge). Since the atomic number is 13, the number of protons is thirteen. In a neutral atom, there would be thirteen electrons. You take away 3. There is 10 electrons in Aluminum Ion. </em>
The correct answer is - 1,180 km.
North America and Europe move away from one another, though on the other end of the plates, the Eurasian and the North American plates are actually merging. Since the rate of moving away is 2 cm per year, and the current distance is 1,184 km between North America and Europe, the distance between them 200,000 years ago was 1,180 km.
To get to the result we only need to multiply the number of years with the annual movement
2 x 200,000 = 400,000
Then divide the result with 100,000, as that is how much cm are in one km
400,000 / 100,000 = 4
And we get 4 km, in this case 4 km less, thus the distance between the two, 200,000 years ago, was 1,180 km.
Answer:living part of the world
Explanation:
Answer:
Naloxone is an antagonist at opioid receptors and heroin is an agonist at opioid receptors
Explanation:
An agonist is a substance that binds to a receptor and causes a biological reaction. In this case, heroine binds to opioid receptors. An antagonist blocks the reaction from the agonist, impeding the receptor's activation. Agonists and antagonists work for specific receptors, and for an antagonist to block an agonist they must bind to the same receptor, like naloxone does with heroin. Giving an antagonist that binds to one receptor and and agonist that binds to a different one means that the antagonist will have no effect.
The answer is A. 36 to 38 molecules
