Answer:

The correct answer to the following question is "TRUE".

Explanation:

  • Hot spots become areas within the mantle of the planet whereby unusually warmer stones melt to form magma which grows through all the surface as well as melt through as well.
  • This seems to be a region where even the water rises through deeper inside the earth as well as warms thru the surface just above, this occurs in locations that are more or less near and nothing like the boundary of the plate.

So that the given is the correct statement.

daser333 [38]

Answer:

the degree to which they decrease CNS activity

Explanation:

Drugs can be classified as;

✓hallucinogens, example is (LSD)

✓ stimulants, example is (cocaine)

✓opium-related painkillers example is (heroin)

✓depressants

Depressants can be regarded as medicines, that lowers neurotransmission levels, that is depressing or reducing arousal or stimulation as regards to various areas of the brain. these could be tranquilizers, as well as hypnotics and

sedatives. They are drugs used in slowing brain activity, therefore, making them useful when treating anxiety, sleep disorders, panic and acute stress reactions.

Example of Depressants are;

✓Xanax

✓Halcion

✓Klonopin

✓Librium

It should be noted that Depressants are often classified according to the degree to which they decrease central nervous system (CNS) activity.

How many protons and electrons are there in a neutral atom of each of the following elements?a. carbonb. fluorinec. tind. nickel
Zolol [24]

Answer:

a.Carbon :proton number =6

             electron number =6

b. Fluorine: proton number=9

                  electron number =9

c. tin:  proton number=50

           electron number =50

d. nickel:proton number=28

           electron number =28

Explanation:

In the neutral state of an atom the number of protons is always equal to the number of electrons and that whats makes it electrically neutral as the positive charges of protons balances the negative charges of electrons.

Why is PCI 5 an exception to the octet rule, while PCI3 is not? Please use at least ONE complete content related
Kitty [74]
P has five electrons, three available to share. Since Cl has seven valence electrons, it can take on one more to accomplish an octet. In PCl3, P’s three valence electrons are evenly distributed among the three chlorine atoms. Whereas, in PCl5 there will be two electrons left over, which is why it is an exception to the octet rule.

Aqueous aluminum bromide and solid zinc are produced by the reaction of solid aluminum and aqueous zinc bromide . write a balanc
Rashid [163]
<span>3 ZnBr2 (aq) + 2 Al (s) ==> 2 AlBr3 (aq) + 3 Zn (s) The unbalanced equation is: ZnBr2 (aq) + Al (s) ==> AlBr3 (aq) +Zn (s) First, count the atoms of each element on each side of the equation: Zn 1,1 Br 2,3 Al 1,1 The zinc and aluminum, but the bromine doesn't match with 2 and 3. So look for the least common multiple of 2 and 3 which is 6 and adjust the quantities on both sides to have 6 bromine atoms on both sides. Do this by having 3 zinc bromide on the left and 2 aluminum bromide on the right, getting: 3 ZnBr2 (aq) + Al (s) ==> 2 AlBr3 (aq) +Zn (s) Now check the atom counts again for both sides: Zn 3,1 Br 6,6 Al 1,2 Now bromine matches, but zinc and aluminum doesn't. But it's easy enough to add an extra aluminum to the left and 2 more zinc to the right. Giving: 3 ZnBr2 (aq) + 2 Al (s) ==> 2 AlBr3 (aq) + 3 Zn (s) Now check the atom counts again: Zn 3,3 Br 6,6 Al 2,2 And they match. So the balanced equation is: 3 ZnBr2 (aq) + 2 Al (s) ==> 2 AlBr3 (aq) + 3 Zn (s)</span>
