The answer to your question is 'No'.

Matter is never created or destroyed. This is called
the Law of Conservation of mass.

In a chemical reaction, the amounts of matter before
and after the reaction are exactly equal.

If there's more matter there after the reaction, then the extra
came from somewhere during the reaction.

If there's less matter left after the reaction, then the rest
went somewhere during the reaction.

The aluminum atom______electrons to form an ion. The ion that is formed is______.

Alchen [17]

The aluminum atom_loses_____electrons to form an ion.

The ion that is formed is_Al³⁺_____.

aluminium has the electronic configuration as 1s² 2s² 2p⁶ 3s² 3p¹

from the electronic configuration , we see that aluminium can attain stability by losing 3 electrons from outer shell.

after losing 3 electrons , the ion formed is given as Al³⁺

hence the correct options to fill in the blanks are lose and Al³⁺

Is block b speeding up or slowing down once it is set into downward motion and the cat is on block a?

stepan [7]

Answer:

The answer is "Slowing down ".

Explanation:

please find the complete question in the attached file.

In this question, if the block B weight were accounted for by kinetic the friction of frame A, because the blocks pushed at a consistent speed throughout the beginning.

Afterward, on block A, the resistance intensity rises, which allows frames to also be negative, which is defined in the graph, that's why the answer Slowing down is correct.
