Hello everyone today. We are being given the following problem, classify the following properties of zinc as quantitative or qualitative. First you wanted to find what each of these mean. So when something is quantitative, this means that it can be measured with a numerical value. So whenever you measure anything within the numerical value it's going to be quantitative tells you how much on the other hand, qualitative. So qualitative on the other hand are things that can be observed but not measured with numerical values so it can only be observed but not measured with numbers. And so we can therefore answer our questions now. So far. First part says Zinc melts at 419.5°C. This is going to be quantitative and I'll just put quan for short quantitative. For our second part zinc has a bluish silver color. This isn't a numerical value, it's an observation. And so too is going to be qualitative or qualify for short For three. The density of zinc is 7.14 g per centimeter cubed. There is a numerical value that has been measured. So this is therefore going to be quantitative. And for the fourth one at room temperature, zinc is brittle and so there's no numerical value. There's just an observation. So that's gonna be quantitative. And so our correct answer is going to be answer choice B Statements one in are quantitative While statements two and 4 are qualitative and with that we've answered the question overall. I hope this helped. And until next time
