Answers
Answer:
It is rigid.
It has a very high melting point.
Explanation:
It conducts electricity. It is rigid. It has a very high melting point. It is magnetic. It is shiny. It rusts.The two properties that are needed for the metal grill out of the options are its rigidity and high melting point.
The rigidity of the metal grill will enable it to hold materials to be grilled without problems while the high melting point will enable the grill to remain intact at the high temperature required for the successful grilling of certain food materials.

a) The density of water _______ as water changes from liquid to steam.
b) As the temperature increases, the rate of diffusion of a gas _______.
c) At constant volume, if the temperature of a gas is decreases, its pressure _______.
Answers
Answer:
a) decrease
b) increase
c) decrease
Explanation:
a) The density of water decreases as water changes from liquid to steam.
The density of substances are higher when their molecules are very close to each other having strongest bonding forces. When water is change from liquid to steam it means water molecules are not close to each other as they are in liquid state because now water is changed into gaseous form and molecules are further apart from each other. Thus, density goes to decrease.
b) As the temperature increases, the rate of diffusion of a gas increase.
As temperature increases molecules gets more kinetic energy and rate of diffusion increases.
c) At constant volume, if the temperature of a gas is decreases, its pressure decreases.
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
As temperature decreases its pressure also goes to decrease and vice versa.

Which reaction is reversible and could reach dynamic equilibrium?
O A. Burning a wood log
O B. Frying an egg
O C. 3H2 + N2 = 2NH3
O D. 2Mg + 02 → 2Mgo
Answers
Answer:
The correct answer is - option C. 3H2 + N2 = 2NH3
Explanation:
If in a chemical reaction the rate of the forward reaction and the rate of reverse reaction are equal, this is called dynamic equilibrium. Due to this equal rate of both side reactions, there is no change in the system. In this type of reaction, the concentration of reactants and products remain constant and the overall reaction is continuous.
Dynamic reactions can be reached by reversible reactions such as 3H2 + N2 = 2NH3 where the concentration of hydrogen and nitrogen and concentration of the ammonia remains constant and rate of the both side are equal.
Answer:
3H2 + N2 = 2NH3

So if you read out loud each sentence and put one of the words from the word bank in the sentence only a few will make sense. So if you read the second sentence out loud with one of the words that you have and one of them sounds correct then you fill it in. Also like your paper says one word can be used multiple times.
