Answer: fluorinehope

Explanation:

Ca-cl is an ionic bond. we know this because the difference between their electronegativities is 2.16.the electronegativity tells us which atom will attract the electron more than the other. hence, chlorine attracts the electron a lot more than the calcium.a difference of more than 1.6 (or 1.7 depending on the source) implies that the electrons are so unevenly shared, that the bond is ionic, rather than polar covalent.

If m = 45g and V = 15ml, what is D in g/ml?

ch4aika [34]

Answer:

3 g/mL

Explanation:

We know that the density of an object can be measured by dividing its mass (g) to its volume (mL).

Formula

D=m/v

Given data:

Mass= 45 g

Volume= 15 mL

Now we will put the values in formula:

D=45 g/ 15 mL= 3 g/mL

How many moles are in 9.25E24 formulas units of sodium acetate?

Lelu [443]

Answer:

<h2>15.37 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

$n = \frac{N}{L} \\$

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

$n = \frac{9.25 \times {10}^{24} }{6.02 \times {10}^{23} } \\ = 15.365448...$

We have the final answer as

<h3>15.37 moles</h3>

Hope this helps you
