Sorry for the late reply. I was trying to find ways to solve this problem on my own and I still don't get it. Yeah, it was the whole solution that was heated up. But I still don't get why it's 400g? I used the molar masses to calculate the masses in grams of the following compounds and these...

Hi, everyone! There's a question I found on website I'm using and the answer key here is given. My question is this, where did the 400g come from? According to the definition of enthalpy of neutralization (chem libretexts), the standard enthalpy change of neutralization is the enthalpy change...

Thank you. Would it be possible to say in the lab report that the data generated by LoggerPro cannot be this precise? I can't imagine why the company who made it would give such small uncertainties for no reason at all.

Would it be reasonable to just not include the error here because it's almost non quantifiable? I could maybe redo the video and put a meter stick on the floor if it's not possible to ignore the uncertainties here. But I don't believe that's part of the things my cousin's class needs to do...

Here's why I'm confused: I recorded a video of a ball moving across the floor and uploaded it to the video analysis software I used. I had to track the moving ball while it moved and I did this while the video was playing in slow motion through the video analysis software. put a dot in the...

You're right. Let me think about this problem some more. I am stuck and although what you said makes sense, I cannot seem to apply it to this problem. Thank you for your help! I'll figure it out and come back here.

I thought about that too, but I think I made a mistake so I scrapped that idea. I thought about acceleration possibly being zero because the boxes are in contact with each other and the top one is not slipping, my equation became: Ff = Fn x μfloor ma = Fn x μfloor 5(0) = 5(9.81) x μfloor μfloor...

Here's a picture of the question: This is a Khan Academy question and although I could just click on hint to find out what the answer is, I think it would be helpful to still ask this here before looking at the answer over there, so that I know what I did wrong. Thank you in advance to anyone...

Yeah, I wasn't really sure how to ask my question because there's so many gaps in my knowledge, I didn't know how to ask what I wanted to find out. Thank you everyone for giving me things to read. I was busy doing just that after reading your replies.

No, it helped me understand what's happening better. Thank you for pointing me to the right direction.

Okay. Since posting this I've been reading about thermodynamics and I think I kind of get it now. Of course, I don't completely get everything since I've just started studying physics. Thank you very much!

Okay. Thank you! I don't think I have any more questions then. Someone mentioned I should read more about latent heat and I think that cleared up a lot of my misconceptions about "heat" in general.

Okay, so I can think of it like how chemical equations have the little reversible arrows? That clears it up for me. Thanks!

What will happen if say, I have both ice and water inside the refrigerator and I set the fridge to exactly 0 degrees Celsius? Since both melting and freezing happen at 0 degrees, what will happen to my water? what about to my ice? Will they stay the same? I know this is an ignorant question, but...

Thank you! I appreciate the detailed explanation.
