Answer:

NaNO3

Explanation:

Hello,

In this case, the required reaction is an acid-base neutralization reaction which is said to be:

$HNO_3+NaOH\rightarrow NaNO_3+H_2O$

There, we see that the sodium displaced the hydrogen in the nitric acid to form sodium nitrate a very used salt in the industry, so, as a result of that displacement, water is formed as the secondary neutralization product. For the above mentioned, answer is NaNO3 .

Best regards.

Answer: NaNO3

Explanation:

A salt sodium nitrate (NaNO3) is formed alongside water (H2O) when HNO3 and a solution of NaOH undergoes a neutralization reaction.

HNO3 + NaOH --------> NaNO3 + H2O

For each trial, enter the amount of heat gained by the chemical system of ammonium nitrate, qrxn. The specific heat of water is

shtirl [24]

This is how to solve the problem:

First, we need to find the qcalorimeter.
The, you must use the equation:
qcalorimeter = Csp + (delta)T 

(delta)T = is the same as what you used for
CSP = you calculated this earlier in lab. "average heat capacity of the calorimeter" 

Hope this helps answer your question.

Choose the compound below that should have the highest melting point according to the ionic bonding model. A) AlN B) MgO C) NaF

iren2701 [21]

Answer:

The correct answer is C.

Explanation:

The compound with the highest melting point according to the ion bond model is the one with the greatest electronegativity difference, since the ion bond is stronger and therefore more difficult to break.

The electronegativity difference is calculated as the electronegativity difference of the atoms of the molecule.

AlN: Al (1,61) and N (3,04) so the difference gives 1,43.

MgO: Mg (1,31) and O (3,44) so the difference gives 2,13.

NaF: Na (0,93) and F (3,98) so the difference gives 3,05.

CaS: Ca (1) and S (2,58) so the difference is 1,58.

RbI: Rb (0.82) and I (2.66) so the difference is 1.84.

Analyzing the different cases, we can conclude that the molecule that presents the greatest difference in electronegativity is NaF, so it will have a higher boiling point due to the attraction force between its atoms.

Have a nice day!

Please answer he questions

"Work done by a constant force on an object is the product of the force and the distance moved by the object in the direction of the force" -textbook

There is work done ONLY if the direction of the force and the direction the item is moving are the same. In figure A, the direction of the force (the lifting) is upwards (defying gravity), and the book is moving upwards, so work is done. In figure B, the force is still moving upwards (the person is carrying the books) but the book is moving to the right, so there is NO work done.

An object has a mass of 20 g and displaces a volume of 5 mL. What is the object's density?

lara [203]

Hey There!:

The density is the quotient between the mass of a material and the volume occupied by it, The density can be expressed for a substance or for a mixture of substances. For example, water density in ambient conditions is equal to 1.00 g/cm3, which means that in 1 cm³ or 1 mL, there are 1.0 g of water. Therefore:

D = m / V

D = 20 g / 5 mL

D = 4,0 g/mL

hope that helps!
