Answer: Eventually, the metal will cool down and warm up. Overtime the metal and the water will come to the same temperature. This happens because the hot metal is giving energy to the water.

Explanation:This process is called thermal equilibrium. It's the same thing as when you put a spoon in hot tea the spoon gets hot and the tea cools down. Hope this helps!!

What is the predicted order of first ionization energies from highest to lowest for lithium (Li), sodium (Na), potassium (K), an
natima [27]

Answer:

Rb > K > Na > Li

Explanation:

Ionization energy increases up the period and up the group.

From the periodic table, we can see that Li is the going to have the highest ionization energy and Rb is going to have the lowest.

Therefore, the correct answer is the first choice

___AsCl3+____H2S-->___As2S3+___HCI​
Alex17521 [72]

Answer:

2 AsCl₃ + 3 H₂S → As₂S₃ + 6 HCl

Explanation:

When we balance a chemical equation, what we are trying to do is to achieve the same number of atoms for each element on both sides of the arrow. On the right of the arrow is where we can find the products, while the reactants are found on the left of the arrow.

We usually balance O and H atoms last.

AsCl₃ + H₂S → As₂S₃ +HCl

<u>reactants</u>

As --- 1

Cl --- 3

H --- 2

S --- 1

<u>products</u>

As --- 2

Cl --- 1

H --- 1

S --- 3

2 AsCl₃ + H₂S → As₂S₃ +HCl

<u>reactants</u>

As --- 2

Cl --- 6

H --- 2

S --- 1

<u>products</u>

As --- 2

Cl --- 1

H --- 1

S --- 3

The number of As atoms is now balanced.

2 AsCl₃ + 3 H₂S → As₂S₃ +HCl

<u>reactants</u>

As --- 2

Cl --- 6

H --- 6

S --- 3

<u>products</u>

As --- 2

Cl --- 1

H --- 1

S --- 3

The number of S atoms is now equal on both sides.

2 AsCl₃ + 3 H₂S → As₂S₃ + 6 HCl

<u>reactants</u>

As --- 2

Cl --- 6

H --- 6

S --- 3

<u>products</u>

As --- 2

Cl --- 6

H --- 6

S --- 3

The equation is now balanced.
