What do u notice about the molecules before and after the chemical reaction
dimaraw [331]

Explanation:

In a chemical reaction, the atoms and molecules produced by the reaction are called products.

In a chemical reaction, only the atoms present in the reactants can end up in the products. No new atoms are created, and no atoms are destroyed.

In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.

Which element is most likely to allow electricity to pass through it?
yKpoI14uk [10]
Hello,
I have attached a periodic table to allow you to further understand my answer. We know elements are categorized in groups of Metals, Nonmetals, and metalloids. Let’s analyze each element. Sulfur is a nonmetal which mean it does not conduct well and does not have a good appearance, the same applies to all the other non metals on this list, including sulfur and helium. Copper is our only answer in which it fits and electricity can pass through/conduct easily. So our answer is copper. I hope this helps you with your assignment.

The pressure of a gas in a tank is 3.20 ATM at 22.0°C if the temperature is increased to 60.0°C what will the new pressure in th
ruslelena [56]

Answer:

P₂ = 3.61 atm

Explanation:

Given data:

Initial pressure of tank = 3.20 atm

Initial temperature = 22.0°C

Final temperature = 60.0°C

Final pressure = ?

Solution:

Initial temperature = 22.0°C (22.0 +273 = 295 K)

Final temperature = 60.0°C (60 +273 = 333)

According to Gay-Lussac Law,

The pressure of given amount of a gas is directly proportional to its temperature at constant volume and number of moles.

Mathematical relationship:

P₁/T₁ = P₂/T₂

Now we will put the values in formula:

3.20 atm / 295 K = P₂/333 K

P₂ = 3.20 atm × 333 K / 295 K

P₂ = 1065.6 atm. K /295 K

P₂ = 3.61 atm
