Calculate the average reaction rate of Cl2 consumed using the following information. H2 + Cl2 yields 2 HCl A table with three co

klemol [59]

Answer : Option D) 2.50 X $10^{-3}$ Mol/(L s)

Explanation: While calculating the average reaction rate for the given reaction in terms of Cl;

$H_{2} + Cl_{2} ----\ \textgreater \ 2HCl$ .

using the rate equation which is;

$\frac{-1}{1}$ $\frac{delta [Cl]}{delta t}$ =

$\frac{- 0.0875 - 0.0625}{10s - 0s}$ = 2.50 X $10^{-3}$ Mol/(L s)

Can someone help me?

Oduvanchick [21]

Answer:

an element with a large number of valence electrons and a large atomic radius

Explanation:

Electronegativity means a tedency when an atom attracts bonding electrons in a covalent bond situation.

» If an atom has many valency electrons [ empty orbitals in outermost shell ], it has difficulty in attracting electrons hence electronegativity low.

» If an atom is large, its nuclear attraction force of incoming electrons is low hence low electronegativity.

A chemist has 2. 0 mol of methanol (CH3OH). The molar mass of methanol is 32. 0 g/mol. What is the mass, in grams, of the sample

natima [27]

The mass, in grams, of the sample of methanol (CH₃OH) is 64 grams.

<h3>How we calculate mass from moles?</h3>

Mass of any substance can be calculated by using moles as:

n = W/M, where

W = required mass

M = molar mass

In the question that:

Moles of methanol = 2mole

Molar mass of methanol = 32g/mole

On putting these values in the above equation, we get

W = n × M

W = 2mole × 32g/mole = 64g

Hence, 64 grams is the mass of the sample.

Water's unique properties, including its high heat capacity, high density, high boiling point and a solid phase that is less den

Deffense [45]

Answer: Option (D) is the correct answer.

Explanation:

As the chemical formula of water is $H_{2}O$ and due to the difference in electronegativity of hydrogen and oxygen atom there is formation of partial positive charge on hydrogen and partial negative charge on oxygen atom.

As a result, polarity arises on water molecule.

Also, there exists hydrogen bonding between molecules of water which is also responsible for providing unique properties to water.

Thus, we can conclude that water's unique properties, including its high heat capacity, high density, high boiling point and a solid phase that is less dense than its liquid phase, can best be attributed to the polarity of the molecule and hydrogen bonding between the molecules.
