Transition metals seem to have fairly even levels of reactivity though it seems they to react more with bases than acids. If I didn’t know from the lessons, I would say alkali and alkaline earth metals weren’t very reactive. 
 
(That's my answer when I did a lab about the reaction of metals for chemistry at least.)

In the Penny Lab that we ran, what is the independent variable? Question 1 options: the soap the number of water drops the penny
motikmotik

Answer:

I'd say it's the number of water drops.

Explanation:

The number of water drops is what you're controlling or purposely controlling and that answer choice makes the most sense out of the other answer choices. So I'd say it's "The Number of Water Drops."

Between a water molecule and an anion, like Cl-, a _____A_____ occurs between a _____B_____ of the water molecule and the anion.
AVprozaik [17]

Between a water molecule and an anion, like Cl-, a hydrogen bon occurs between hydrogen atom of the water molecule and the anion.

<h3>What is hydrogen bond?</h3>

Hydrogen bond is a weak bond between two molecules resulting from an electrostatic attraction between a proton in one molecule and an electronegative atom in the other. Hydrogen atom in water molecule attract anion due to presence of hydrogen bond.

So we can conclude that hydrogen bond occurs between hydrogen atom of the water molecule and the anion.

Answer : The volume of gas will be, 113.5 L

Explanation :

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}

where,

P_1 = initial pressure of gas = 60 atm

P_2 = final pressure of gas = 30 atm

V_1 = initial volume of gas = 29 L

V_2 = final volume of gas = ?

T_1 = initial temperature of gas = 115 K

T_2 = final temperature of gas = 225 K

Now put all the given values in the above equation, we get:

\frac{60atm\times 29L}{115K}=\frac{30atm\times V_2}{225K}

V_2=113.5L

Therefore, the volume of gas will be, 113.5 L
