Answer:

<h2>The P wave will be the first wiggle that is bigger than the rest of the little ones (the microseisms). Because P waves are the fastest seismic waves, they will usually be the first ones that your seismograph records. The next set of seismic waves on your seismogram will be the S waves</h2>

Ethanoic acid, CH3COOH, ionizes to form an ethanoate ion (CH3COO-) in aqueous solution. what else does it form? is it a monoprot

barxatty [35]

Ethanoic acid ionizes in aqueous solutions to form two ions which are $CH_3COO^-$ and $H^+$

<h3>Ionization of ethanoic acid</h3>

Ethanoic acid goes by the chemical formula $CH_3COOH$ .

In aqueous solutions, it ionizes as a monoprotic acid according to the following equation:

$CH_3COOH ---- > CH_3COO^- + H^+$

A monoprotic acid is an acid that is able to donate only a proton. Hence, ethanoic acid is said to be monoprotic because it ionizes in aqueous solutions to produce a single $H^+$

Formula New Combination Predicted Formula

creativ13 [48]

Answer:

<span>Formula    New Combination Predicted Formula
</span>

NaCl            potassium + chlorine                KCl

AlCl₃             aluminum + fluorine                AlF₃

CO₂    tin + oxygen                              SnO₂

MgCl₂           calcium + bromine                   CaBr₂

HCl               cesium + iodine                       CsI

<span> CCl₄              silicon + bromine                     SiBr₄</span>

Explanation:

1) The question is incomplete. The first part is missing.

This is the first part of the question.

<span>Applying the principle that the elements of a particular column in the Periodic Table share the same chemical properties, complete the following chart. The first one has been done for you.
</span>

2) This is the given chart:

<span>Formula    New Combination Predicted Formula
</span>

Cu₂O           silver + oxygen                          Ag₂O   ← this is the example.

NaCl            potassium + chlorine

<span> AlCl₃             aluminum + fluorine </span>

CO₂    tin + oxygen

<span> MgCl₂           calcium + bromine </span>

<span> HCl               cesium + iodine </span>

<span> CCl₄              silicon + bromine </span>

3) This is how you find the new formula to complete the chart.

i) NaCl            potassium + chlorine

Since potassium is in the same group of sodium, you predict that in the new formula Na is replaced by K giving KCl.

ii) AlCl₃             aluminum + fluorine

Since fluorine is in the same group that Al, then you predict that in the new formula Cl is replaced by F leading to AlF₃

iii) CO₂    tin + oxygen

Since tin is in the same group that C, you predict that in the new formula C is replaced by Sn leading to SnO₂

iv) MgCl₂           calcium + bromine

Since calcium is in the same group that Mg, and bromine is in the same group that Cl, you predict thea in the new formula calcium replaces Mg and bromine replaces Cl, leading to CaBr₂

v) HCl               cesium + iodine

Since H is in the same column that cesium and Cl is in the same colum that iodine, you predict that in the new formula Cs replaces H and I replaces Cl leading to: CsI

<span> vi) CCl₄              silicon + bromine
</span>

Since silicon is in the same column that C and bromine is in the same column that Cl, you predict that in the new formula Si replaces C and Br replaces Cl, leading to SiBr₄
