Answer:

In styrene, there is a phenyl group which is electron-withdrawing. So the electronic density in the double bonds increases, hence easy to associate as monomers. While in methoxystyrene, there is a carbonyl group which is not electron deficient. so no easy association with monomers.

Explanation:

${ \sf{styrene \: is \: phenylethene \: }} \\ { \sf{its \: polymer \: is \: polystyrene}}$

Determine which of the following elements would gain electrons when becoming ions: I. Hydrogen II. Helium III. Sulfur IV. Fluori

klio [65]

Hydrogen, iron, and gallium is the correct answer. Hence, option B is correct.

<h3>What is an electron?</h3>

An electron is a negatively charged subatomic particle.

Let us take another look at the periodic table. The periodic table is composed of metals, metalloids and nonmetals.

Metals lose electrons more easily, that is why they form cations. Metals are found on the left-hand side of the periodic table.

As we move away from the left-hand side of the periodic table, the ability to form cations decreases as metallic character decreases and elements become more nonmetallic.

The noble gas helium rarely loses electrons. Fluorine would rather accept an electron to form a negative ion.

Hence, the elements hydrogen, iron and gallium are metals hence they lose electrons more easily.

Hence, option B is correct.

Write the equilibrium-constant expression for the reactionA(s)+3B(l)↽−−⇀2C(aq)+D(aq)A(s)+3B(l)↽−−⇀2C(aq)+D(aq)in terms of [A], [

Ilia_Sergeevich [38]

Answer:

$K_{c} = [\text{C}]^{2}[\text{[D]}$

Explanation:

$\rm A(s)+3B(l) \, \rightleftharpoons \, 2C(aq)+D(aq)$

The general formula for an equilibrium constant expression is

$K_{c} = \dfrac{[\text{Products}]}{[\text{Reactants}]}$

Solids and liquids are not included in the equilibrium constant expression.

Thus, for this reaction,

$K_{c} = [\textbf{C}]^{\mathbf{2}}\textbf{[D]}$

Answer: The number of grams of $H_2$ in 1620 mL is 1.44 g

Explanation:

According to ideal gas equation:

$PV=nRT$

P = pressure of gas = 1 atm (at STP)

V = Volume of gas = 1620 ml = 1.62 L (1L=1000ml)

n = number of moles = ?

R = gas constant = $0.0821Latm/Kmol$

T =temperature = $273K$

$n=\frac{PV}{RT}$

$n=\frac{1atm\times 16.2L}{0.0821Latm/K mol\times 273K}=0.72moles$

Mass of hydrogen = $moles\times {\text {Molar mass}}=0.72mol\times 2g/mol=1.44g$

The number of grams of $H_2$ in 1620 mL is 1.44 g

A sample of an element has a mass of 34.261 grams and a volume of 3.8 cubic centimeters. To which number of significant figures

nikklg [1K]

The answer is (2). To calculate the density, you need to divide the mass with volume. When doing division, the significant figures of result is the minimal of the numbers using before. So the answer is 2.
