Copper is a metal with the ability to conduct electricity, so copper wires are often used in small household appliances. The abi

lity to
conduct electricity is a drag and drop answer here property of copper. Iron, on the other hand, reacts with oxygen to form iron oxide, also
known as rust. The ability of iron to rust is a drag and drop answer here property of the metal As scientists characterize certain metals, they
investigate physical properties like drag and drop answer here and chemical properties like drag and drop answer here.

Answer:

physical property

Chemical property

melting point

Reactivity with a strong acid

Explanation:

The ability to conduct electricity is a physical property of copper. Most electrical cables are made of copper owing to its high electrical conductivity.

The rusting of iron is a chemical reaction. Rust is actually hydrated iron III oxide. Hence it is a chemical property of iron.

The melting points of metals can be used to classify them. The greater the density of metals, the higher their melting point.

The ability of metals to react with acids separates metals into highly reactive, moderately reactive and unreactive metals.

BY ANSWERING THIS QUESTION UR PUTTING IT ON UR MOM's LIFE THAT U WON'T STEAL MY POINTS.
Yakvenalex [24]

Answer:

T_2=-125.58\°C

Explanation:

Hello!

In this case, considering the Gay-Lussac's law which describes the pressure-temperature behavior as a directly proportional relationship by holding the volume as constant, we write:

\frac{T_1}{P_1} =\frac{T_2}{P_2}

Whereas solving for the final temperature T2, we get:

T_2=\frac{T_1P_2}{P_1}

Thus, we plug in the given data (temperature in Kelvins) to obtain:

T_2=\frac{(22+273.15)K*1.75atm}{3.50atm} \\\\T_2=147.58K-273.15\\\\T_2=-125.58\°C

Best regards!

Which of the following statements is (are) true about enzyme-catalyzed reactions? a. The reaction is faster than the same reacti
Brums [2.3K]

Answer : The correct option is A.

Explanation :

Enzyme-catalyzed reaction :

Enzyme act as a biological catalyst and the role of catalyst is to increase the rate of chemical reaction by lowering the activation energy.

Most of the chemical reactions are slow in the absence of enzyme but in the presence of enzyme, the reaction become faster. That means the Enzyme accelerate the rate of reaction.

Therefore, the correct answer is the reaction is faster than the same reaction in the absence of the enzyme.
