If the electronnegavity difference between elements A and X is 0.8, the bond in AX will most likely be what?

siniylev [52]

Answer:

Polar covalent bond

Explanation:

When the electronegativity difference between two elements A and X is 0.8, the bond AX formed will most likely be a polar covalent bond.

A polar covalent bond is one whose electronegativity difference is between 0.5 and 2.1.

In such a bond type, we have heteronuclear species with one of the species having a higher electronegativity value.

When electronegativity difference is less than 0.5, a non-polar covalent bond forms.
If the value is greater than 2.1, an ionic bond will form.

Which term describes this reaction? upper c upper h subscript 3 upper b r (a q) plus upper o upper h superscript minus (a q) rig

Veronika [31]

The reaction is a substitution reaction since bromide ion was replaced by hydroxide ion.

<h3>What is a chemical reaction?</h3>

A chemical reaction is a change which results in a the permanent rearrangements of the atoms and constituents of a substance such that new substances are formed.

The given reaction is a as follows:

$CH_3Br (aq) + OH^{-} (aq) \rightarrow CH_3OH (aq) + Br^{-} (aq) \\$

Bromide ion was replaced by hydroxide ion.

Therefore, the reaction is a substitution reaction.

How many moles are in 124.7 g of Ba(OH)2

Alekssandra [29.7K]

Answer:

0.73 mol

Explanation:

No. of moles(n)= Given mass/molar mass.

Given mass=124.7g

Molar mass of Ba(OH)2= Molar mass of (Barium+2Oxygen+2Hydrogen)=137+32+2=171g

No. of moles= 124.7g/171g=0.73 mol

Imagine that the apparent weight of the crown in water is <img src="https://tex.z-dn.net/?f=W_%7Bapparent%7D" id="TexFormula1" t

Ahat [919]

Answer : The crown is not made of pure (100%) gold.

Explanation :

Formula used :

$\frac{W_{apparent}}{W_{actual}}=1-\frac{\rho_w}{\rho_c}$

where,

$W_{apparent}$ = apparent weight of the crown in water = 4.50 N

$W_{actual}$ = actual weight = 5.00 N

$\rho_w$ = density of water = $1.00g/cm^3$

$\rho_c$ = density of crown = ?

Now put all the given values in the above formula, we get:

$\frac{4.50N}{5.00N}=1-\frac{1.00g/cm^3}{\rho_c}$

$\rho_c=10g/cm^3$

Density of crown < Density of gold

$10g/cm^3$

Thus, the crown is not made of pure (100%) gold.
