Which property is best to use when determining the strength of an ionic bond in a solid?

Shtirlitz [24]

I think the best property to use is electronegativity since that is how much it attracts/wants electrons. The larger the difference in electronegativity is between two atoms, the stronger the ionic bond will be. This is also why two atoms need to have a minimum difference between the electronegativity to be considered ionic and not covalent.

The temperature of a piece of Metal X with a mass of 95.4g increases from 25.0°C to 48.0°C as the metal absorbs 849 J of heat. W

Nataly_w [17]

Answer:

c = 0.38 J/g °C

Step-by-step explanation:

We have,

Mass of metal X is 95.4 g

Initial temperature was 25°C and final temperature is 48°C.

The metal absorbs 849 J of heat

The heat absorbed due to change in temperature is given by :

$Q=mc\Delta T\\\\c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{849}{95.4\times (48-25)}\\\\c= 0.38\ J/g^{\circ} C$

So, the specific heat of metal X is 0.38 J/g °C.

Write an equation in slope-intercept

NemiM [27]

For this case we have that, by definition, the equation of a line in the slope-intersection form is given by:

$y = mx + b$

Where:

m: It's the slope

b: It is the cut-off point with the y axis

On the other hand, we have that if two lines are parallel then their slopes are equal.

We have the following equation of the line:

$3x-y = 5$

Rewriting we have:

$y = 3x-5$

Thus, the slope of the lines is $m_ {1} = 3$

Then, a parallel line will have slope $m_ {2} = 3$

Thus, the equation of the new line will be given by:

$y = 3x + b$

To find the cut-off point "b", we substitute the point through which the line passes:

$-2 = 3 (-1) + b\\-2 = -3 + b\\-2 + 3 = b\\b = 1$

Finally the equation is:

$y = 3x + 1$

ANswer:

$y = 3x + 1$
