Which of the following represents a chemical property of hydrogen gas?

Accepted Answer

Hey there, welcome back. Alright. So you're going to select a chemical property for uranium. So we don't actually need to know the chemical properties of uranium. What this problem is actually testing is, do we know the difference between a chemical property and a physical property rights. So the chemical properties, something that we observe through a chemical reaction, Right? So we need to take uranium and put it through some sort of a reaction in order to observe that chemical property. The physical property is just something that we can look with our eyes without having to perform any chemical reactions. Right? We can just either take a look at the substance, we can touch it. We can wait. Those all would be physical properties. So the first one silver, white and color. So color obviously is a physical property. You don't actually need to do any reactions with uranium to find its color. So this is not a physical or it's not a chemical property. It's a physical property that we're going to say physical be react with cold water. So the you know the word here that we need to pay attention is reacts, right? So this is a reaction. Um so uranium is going to react with cold water when they come into contact and that is going to be the chemical property of uranium. So we're going to say that's the answer. We're going to take a look at the other ones. Low density. So density we know is a physical property, right? In order to find the density or weight or volume of something. You don't actually need to perform any chemical reactions has a strong odor. You can just smell it with your nose. You don't have to do anything to do that and then ductile and malleable. So it's just meaning that it's soft. You can shape it into different forms, shapes. I mean, I wouldn't be touching uranium obviously, but this is a physical property. So the only property that is chemical here is beef. So that has to be the answer. So you didn't actually need to know that uranium specifically reacts with cold water. You just need to know the difference between chemical and physical properties. Alright folks, thank you so much for watching.
