Answer:

They have mobile charged particles.

Explanation:

Plasma refers to very hot matter such that the electrons in matter are ripped away from the atoms leading to the formation of an ionized gas.

We know that the carriers of electricity are charged particles. Any state of matter that has an abundance of charge carriers will definitely be a good conductor of electricity.

Therefore, plasmas are good conductors of electricity because they have a lot of mobile charged particles.

Choose the following statements that show evidence for a chemical reaction.
Leno4ka [110]

Explanation:

A chemical reaction is defined as the reaction in which bonds between the reactants either break or form which leads to the formation of a new substance.

For example, 2Li + Cl_{2} \rightarrow 2LiCl

So, when we drop a sodium metal into water then it produces a frizzing sound which shows the metal is reacting with water.

We know that when two aqueous solutions chemically react with each other then it may lead to the formation of an insoluble substance which is known as precipitate.

This means that formation of a precipitate is also a chemical reaction.

Thus, we can conclude that following are the statements which show evidence for a chemical reaction.

  • Dropping sodium metal into water produces fizzing.
  • Mixing two aqueous solutions produces a precipitate.

Which type of compounds are likely to be nonconductors in their solid forms but conductors when they are mixed with water
Blizzard [7]
Ionic compounds. because when in solid form they are held firmly in place therefore they cannot move to conduct electric current.

A balloon that had a volume of 3.50 L at 25.0°C is placed in a hot room at 40.0°C. If the pressure remains constant at 1.00 atm,
inna [77]

Answer:

3.676 L.

Explanation:

  • We can use the general law of ideal gas: PV = nRT.

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R  is the general gas constant,

T is the temperature of the gas in K.

  • If n and P are constant, and have different values of V and T:

(V₁T₂) = (V₂T₁)

  • Knowing that:

V₁ = 3.5 L, T₁ = 25°C + 273 = 298 K,

V₂ = ??? L, T₂ = 40°C + 273 = 313 K,

  • Applying in the above equation

(V₁T₂) = (V₂T₁)

∴ V₂ = (V₁T₂)/(T₁) = (3.5 L)(313 K)/(298 K) = 3.676 L.
