What is another name for a compound known as a salt? Molecule Covalent compound Element Ionic compound

1 answer:

5 0

Take a look at their electronegativity values for this one. Electronegativity is the relative attraction that a atom in a molecule has for the shared pair of electrons in a covalent bond<span>. Salt is Sodium Chloride which is NaCl. Na has an electronegativity value of 0.93. Cl has an electronegativity value of 3.16. The difference between the two is 2.23. This is much higher than 1.7 (a pure covalent bond e.g. Oxygen-Oxygen bond O2) therefore it is a highly ionic compound. If this was less than 1.7 it would be a polar covalent molecule. </span>

The measured quantity 0.00410 g written in scientific notation is _______. Using prefixes, the number can be written as ________

vovangra [49]

Answer:

4.10x10⁻³g.

4.10 mg.

Explanation:

Hello,

In this case, considering the given number, we can see it has two digits after the first nonzero digit that is four (4) which is also at the third decimal place, it means that the scientific notation has a negative power as it is at the left of the given zeros, therefore it is:

4.10x10⁻³g.

Moreover, since the proper prefix for the factor x10⁻³ is milli, the number with prefix is:

4.10 mg.

Best regards.

An empty container weighs 80.21 g. it is filled with 20.14 mL of an unknown liquid, and the total weight of the container and li

tatiyna

Answer:

1.242 g/mL

Explanation:

Step 1: Given data

Mass of the empty container (m₁): 80.21 g

Mass of the filled container (m₂): 105.22 g

Volume of the unknown liquid (V): 20.14 mL

Step 2: Calculate the mass of the liquid

The mass of the liquid is equal to the difference between the mass of the filled container and the mass of the empty container.

$m = m_2 - m_1 = 105.22g - 80.21 g = 25.01 g$

Step 3: Calculate the density of the unknown liquid

The density of the liquid is equal to its mass divided by its volume.

$\rho = \frac{m}{V} = \frac{25.01g}{20.14mL} = 1.242 g/mL$
