This is a decomposition reaction because the compound of water is being broken up into 4 hydrogen molecules and 2 Oxygen molecules. Hope this helps!

Answer:

The correct answer is water electrolysis.

Explanation:

Water electrolysis is the decomposition of water (H2O) into the gas oxygen (O2) and hydrogen (H2) using a continuous electric current, supplied by a power source, which can be a battery or a battery, which is connected by electrodes to water. This reaction is endothermic, and the products of the reaction are hydrogen and oxygen in a gaseous state.

Have a nice day!

Why does nuclear charge increase as you go left to right across a period
MariettaO [177]

 The atomic number increases moving left to right across a period and subsequently so does the effective nuclear charge. Therefore, moving left to right across a period the nucleus has a greater pull on the outer electrons and the atomic radii decreases.

1) Why are the antimony and beryllium ions so small? Differentiate between the causes.
Viefleur [7K]
1. For this question, the adjective small must be percepted in a relative sense. This is because it is not the smallest ion (that would be hydrogen). It could be that the antimony and beryllium ions are smaller compared to their neutral forms. This is because they donate electrons when ionized. As a result, the electrons are reduced, so does the electron cloud which makes the radius much smaller.

2. The periodic table is arranged in terms of increasing atomic number. For neutral atoms, the number of protons (atomic number) is equal to the number of electrons. So, the farther we go down the table, the higher the atomic number. The higher the atomic number, the bigger the electron cloud which makes the atomic radius bigger. Because by definition, atomic radius is the length from the nucleus to the farthest electron from the nucleus.

The rate of geologic processes can happen quickly or take a long time.
erik [133]

Answer:

Take a long time

Explanation:

Geology is defined as a science mostly concerned with the study of the history of the earth as recorded in different rocks formations.

Geologic processes are events that occur on a geological timescale which may span across many centuries.

The four major geologic process are known to include; impact cratering, volcanism, tectonics, and erosion.

Convert 1.45 × 1024 atoms of carbon to moles of carbon.
anygoal [31]
1 mol = 6.02 * 10^23 atoms of carbon
x mol = 1.45 * 10^24 atoms of carbon

1/x =6.02*10^23 / 1.45 * 10^24

6.02 * 10^23 x = 1.45 * 10^24
x = 1.45 * 10^24 / 6.02 * 10^23
x = 2.41 mols of carbon
