Explanation:

General reaction of acid in water is as follows:

HCl + H2O = H3O+ + Cl-

Thus Acids increase the concentration of hydronium ions in solution by donating hydrogen ions to water molecules is true

Answer:

Density = 4.06 * 10^14

Explanation:

Givens

r = 1 * 10^-13 cm

m = 1.7 * 10^-24 grams

Formula

V = 4/3 * pi * r^3

D = m/V

Solution

Put the givens into the formula.

V = (4/3) 3.14 * (1 * 10^-13)^3 Find the value for r^3

V = (4/3) 3.14 * 1 * 10^-39 Find the volume. Indicate divide by 3

V = 1.256 10^-38/3

V = 4.1867 * 10^-39

Density = m / v

Density = 1.7*10^-24/4.1867*10^-39 Do the division

Density = .406 * 10^(-24 + 39)

Density = .406 * 10^15 grams/ cm^3

Answer: Density = 4.06 * 10^14

<h3>Explanation:</h3>

<u>Step 1: Define</u>

[RxN - Balanced] Fe₃O₄ + 4H₂ → 3Fe + 4H₂O

[Given] 705.0 g H₂O

<u>Step 2: Identify Conversions</u>

[RxN] 4 mol H₂O → 1 mol Fe₃O₄

Molar Mass of H - 1.01 g/mol

Molar Mass of O - 16.00 g/mol

Molar Mass of Fe - 55.85 g/mol

Molar Mass of H₂O - 2(1.01) + 16.00 = 18.02 g/mol

Molar Mass of Fe₃O₄ - 3(55.85) + 4(16.00) = 231.55 g/mol

<u>Step 3: Convert</u>

Set up stoich: $\displaystyle 705.0 \ g \ H_2O(\frac{1 \ mol \ H_2O}{18.02 \ g \ H_2O})(\frac{1 \ mol \ Fe_3O_4}{4 \ mol \ H_2O})(\frac{231.55 \ g \ Fe_3O_4}{1 \ mol \ Fe_3O_4})$
Multiply/Divide/Cancel units: $\displaystyle 2264.74 \ g \ Fe_3O_4$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 4 sig figs.</em>

2264.74 g Fe₃O₄ ≈ 2265 g Fe₃O₄

Explain all ways your atom and symbol for it would change if you removed 2 electrons from the atom

MissTica

Each atom/element has an electron configuration

The electron configuration shows the energy level of the electron

Each electron configuration has 4 quantum numbers, namely n, l, ml, and ms

n = the principal
l = the angular momentum / azimuthal
ml = the magnetic
ms = the electron-spin

We make an example of the element Mg which is in group 2 with the atomic number 12

Electron configuration of Mg: [Ne] 3s² or 1s² 2s² 2p⁶ 3s²

if Mg removes 2 electrons then Mg will form a positive ion (cation) Mg²⁺

This cation is included in the monatomic ion because it is formed from one element (in contrast to the polyatomic ion, which is formed from two or more elements such as SO₄²⁻, ClO₃⁻)

Electron configuration of Mg²⁺ : 1s² 2s² 2p⁶

So atoms can be positively or negatively charged depending on removing or attracting electrons
