Answer:

Explanation:

When two atoms share electrons, a covalent bond is formed. The more electrons shared between atoms, the stronger the bond. Single bonds have two electrons shared, double bonds have four electrons shared, and triple bonds have six electrons shared.

Therefore, triple bonds are the strongest as they require more energy to break.

Hope that helps.

How many moles of KClO3 must decompose in order to produce 9 moles of oxygen gas (O2) using the following reaction by completing

mezya [45]

Answer: 6 moles of $KClO_3$ will be decomposed.

Explanation:

We are given:

Moles of oxygen gas produced = 9 moles

The chemical equation for the decomposition of $KClO_3$ follows:

$2KClO_3\rightarrow 2KCl+3O_2$

By the stoichiometry of the reaction:

If 3 moles of oxygen gas is produced by 2 moles of $KClO_3$

So, 9 moles of oxygen gas will be produced by = $\frac{2}{3}\times 9=6mol$ of $KClO_3$

Hence, 6 moles of $KClO_3$ will be decomposed.

What is the value for the kinetic energyfor a n = 2 Bohr orbit electron in Joules?

Vladimir [108]

Answer:

K.E. = 5.4362 × 10⁻¹⁹ J

Explanation:

The expression for Bohr velocity is:

$v=\frac{Ze^2}{2 \epsilon_0\times n\times h}$

Applying values for hydrogen atom,

Z = 1

Mass of the electron ( $m_e$ ) is 9.1093×10⁻³¹ kg

Charge of electron (e) is 1.60217662 × 10⁻¹⁹ C

$\epsilon_0$ = 8.854×10⁻¹² C² N⁻¹ m⁻²

h is Plank's constant having value = 6.626×10⁻³⁴ m² kg / s

We get that:

$v=\frac {2.185\times 10^6}{n}\ m/s$

Given, n = 2

So,

$v=\frac {2.185\times 10^6}{2}\ m/s$

$v=1.0925\times 10^6\ m/s$

Kinetic energy is:

$K.E.=\frac {1}{2}\times mv^2$

So,

$K.E.=\frac {1}{2}\times 9.1093\times 10^{-31}\times ({1.0925\times 10^6})^2$

K.E. = 5.4362 × 10⁻¹⁹ J

What is the mole fraction of water in 200g of 95% (by mass) ethanol, C2H5OH? C2H5OH= 46g/mol

zheka24 [161]

For the given 200 g of 95% ethanol solution, ethanol is 190g and water is 10g. We determine the number of moles per component.
ethanol: (190 g ethanol) / (46 g/mole) = 4.13 moles
water: (10 g water)/(18 g/mole) = 0.55 moles

Total moles of the solution is 4.68 moles

Mole fraction of water: = 0.55 moles/4.68 moles = 0.117
