Answer:

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d² or [Ar] 3d² 4s²

Explanation:

Electron configuration can basically be referred to as the location of electron; how the electrons are arranged in the orbitals of the atoms.

Following Aufbau principle, electrons are arranged in the following order of orbitals.

1s 2s 2p 3s 3p 4s 3d and so on.

The s can hold a maximum of 2 electrons, p can hold a maximum of 6 electrons and d can hold a maximum of 10 electrons.

Titanium has an atomic number of 22. So the arrangement is given as;

Ti = 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d²

The short hand notation is given as;

[Ar] 3d² 4s²

Solid chromium (III) reacts with oxygen gas to form solid Cr2O3. What is this type of reaction?
mafiozo [28]

Answer:

.081 g of O2

Explanation:

4Cr + 3O2 -----> 2Cr2O3

.175 g Cr x [1 mole / 52.0 g] x [2 moles Cr2O3 / 4 moles Cr] x [152 g / 1 mole] = .256 g of Cr2O3

.175 g Cr x [1 mole / 52.0 g] x [3 moles O2 / 4 moles Cr] x [32 g / 1 mole] = .081 g of O2

Seawater is composed of salt, sand, and water. is seawater a heterogeneous or homogeneous mixture? explain
Umnica [9.8K]

A mixture is said to be homogeneous if its composition is uniform throughout the mixture. They are referred to as solutions. On the other hand, heterogeneous mixture does not have uniform composition. The substances present in the mixture have visible difference or phases.

Sea water is composed of salt, sand and water. Here, salt and water form homogeneous mixture but due to the presence of sand, the mixture is heterogeneous. Salt dissolves in water and the solution has uniform composition but sand does not dissolve in water, even after vigorous mixing, after some time it settles at the bottom resulting formation of layers. Thus, sea water containing salt, water and sand is a heterogeneous mixture.

Why is it important to control all of the variables except one in an experiment?
Ad libitum [116K]
Any given experiment has numerous control variables, and it's important for a scientist to try to hold all variables constant except for the independent variable. If a control variable changes during an experiment, it may invalidate the correlation between the dependent and independent variables.



It’s copied and pasted from google so make sure to put it in your words :)
