Environmental researchers have collected rain acidity data for several decades. They want to see if there is any evidence that attempts to reduce industrial pollution have produced a trend toward less acidic rainfall. They should display their data in a Time plot.

Acid Rain: What Is It?

Any type of precipitation that contains acidic elements, such as sulfuric or nitric acid, that falls to the ground from the atmosphere in wet or dry forms is referred to as acid rain, also known as acid deposition. Rain, snow, fog, hail, and even acidic dust might fall under this category.

Only one variable—the acidity level of the rainfall over a specific time period—will be present in the data used to create the plot or graph. But because the gbwre data is time-dependent, the plot is a time series. As a result, this is a two-dimensional univariate plot with time on the other axis and the acidity label Rainfall on the first. The time series plot is therefore the appropriate type of graph to use to illustrate this kind of data.

What is the single factor that classifies an element as a transition metal?
klasskru [66]
The answer is b) the highest occupied orbital is a “d”orbital.
Transition metals are metals where the highest energy electrons partially fill the d subshells. There are some elements with complete d subshells but on forming cations they have incomplete d subshells.
These transition metals have some properties that are different from the other metals .

5.00 moles of a binary, group 2 oxide are found to have a mass of 521 g. Identify the group 2 metal
andrey2020 [161]

5.00 moles of a binary, group 2 oxide are found to have a mass of 521 g. The group 2 metal is Strontium.

According to question 5 moles of binary group 2 metal oxide mass =521  g

So, 1-mole metal oxide mass will be =521 / 5=104.2 g

Now, as metal oxide is group 2 oxide so metal: oxygen =1: 1

So the mass of metal is =104.2-16=88.2 gm (as the atomic mass of oxygen is 16 g

Therefore, the metal is Strontium(Sr) whose atomic mass is 87.62 g which is nearly 88.2 gm

So, the formula of metal oxide is SrO

The group two metal here is Sr which is strontium and lies in the same group as calcium.
