<span>Galvanized steel is preferred for outdoor uses because it is ideal to prevent rotting/corrosion A steel will rot more quickly if it's exposed to a larger amount of oxygen and H2O , which will exist if we put it oudoor Coating the steel with additional zinc will slow down the process</span>

A cubic object has a volume of 250 cm. What is its density if its mass is 5 points<br> 257.3 g?
ira [324]

Answer:

<h3>The answer is 1.03 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question

mass = 257.3 g

volume = 250 cm³

We have

density =  \frac{257.3}{250}  \\  = 1.0292

We have the final answer as

<h3>1.03 g/cm³</h3>

Hope this helps you

O, li, c which electrons experience the greatest effective nuclear charge? express your answer as a chemical formula.
Nataly_w [17]
<span>The effective nuclear charge of an atom = total electrons - inner electrons For O, ENC = 8 - 2 = 6 For Li, ENC = 3 - 2 = 1 For C, ENC = 6 - 2 = 4 The electrons in O experience the greatest effective nuclear charge and that is why O is smaller than C (which is smaller than Li).</span>

The label on a bottle shows the following information: C2H4O, molar mass 44.06 grams per mole. The formula must be:
Ivahew [28]
The formula can be empirical because the subscripts are reduced to the lowest fraction. 

To check if this formula is also the molecular formula we can check by obtaining the molar mass of the compound it is equal to the given molar mass. Thus 

12*2 + 4*1 + 16 = 44 g/mol

this is ~equal to the given molar mass thus the given equation can be both empirical and molecular.
