PLEASE HELP ILL GIVE U BRAINLIEST What's something you learned about the periodic table

Chemistry

Answer:

The periodic table of elements puts all the known elements into groups with similar properties. This makes it an important tool for chemists, nanotechnologists, and other scientists. If you get to understand the periodic table and learn to use it, you'll be able to predict how chemicals will behave.

Answer:

Okayy

Explanation:

The periodic table arranges the chemical elements

All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods

It have many properties. Each column is called a group.

ALSO Metals are placed on the left-hand side of the periodic table , and non-metals on the right.

Metalloids can also be called semimetals. On the periodic table, the elements colored yellow, which generally border the stair-step line, are considered to be metalloids.

Ladybugs eat aphids on plants. Ajoy counts the number of ladybugs in one square meter of his garden.
kirza4 [7]

To estimate the number of ladybugs in the entire garden, Ajoy needs the dimension of the garden.

<h3>What is a dimension?</h3>

Dimensions in mathematics are the measure of the size or distance of an object or region or space in one direction.

Dimensional measurement is of fundamental importance for interchangeability and global trade.

Hence, to estimate the number of ladybugs in the entire garden, Ajoy needs the dimension of the garden.

What is the empirical formula for CaCo3?*
GalinKa [24]

This problem is requiring the empirical formula for CaCO₃, which is its molecular formula, and turns out to be equal, this is A. CaCO3 according to the following:

<h3>Empirical formulas:</h3><h3 />

In chemistry, molecular formulas show both the actual type and number of atoms in a chemical compound, based on the elements across the periodic table and the subscripts standing for the number of atoms in the compound.

However, the empirical formula is a reduced expression of the molecular one, which shows the minimum number of atoms in a compound after simplifying to the smallest whole numbers.

In such a way, since the given compound is CaCO₃ and both Ca and C have a one as their subscript, it is not possible to simplify any further and therefore the empirical formula equals the molecular one this time, making the answer to be A. CaCO3.

A driver blows 0.75 -L air bubble 10 m under water. As it rises to the surface, the pressure goes from 2.25 atm to 1.03 atm. Wha
kakasveta [241]

Answer:

1.64 L

Explanation:

P₁V₁ = P₂V₂

P₁ = 2.25 atm

V₁ = 0.75 L

P₂ = 1.03 atm

V₂ = ?

(2.25 atm)(0.75 L) = (1.03 atm)V₂

[(2.25 atm)(0.75 L)]/(1.03 atm) = V₂

V₂ = 1.64 L
