NaCl consists of a salt, which is a nonmetal (Na) and Cl, which is a metal. When a nonmetal and a metal are combined, it makes the compound ionic.

Answer is: 1) NaCl.

NaCl is sodium chloride, ionic compound.

Ionic compounds are made of ions held together with ionic bonds.  

Ionic bond forms when a cation transfers its extra electron to an anion who needs it.  

Electronegativity (χ) is a property that describes the tendency of an atom to attract a shared pair of electrons.  

Δχ(Na-Cl) = 3.2 - 0.95 = 2.25; electronegativity difference between sodium and chlorine.

When the electronegativity difference is greater, the bond polarity is increasing.

Other compound have covalent polar bonds.

Assuming that the following reaction is performed at stp, how many ml of oxygen are needed to react with 50ml of h2 gas in synth
densk [106]
The balanced chemical reaction is written as:

2H2+O2 = 2H2O

We are given the amount of H2 gas to be used in the reaction. This will be used as the starting point for the calculations. We calculate as follows:

.050 L H2 ( 1 mol H2 / 22.4 L H2 ) ( 1 mol O2 / 2 mol H2 ) ( 22.4 L / 1 mol ) = 0.025 L O2 or 25 mL O2

assuming that each human being has 60 trillion body cells in that the earths population is 6 billion calculate the total number
sesenic [268]

3.6 x 10²³

Explanation:

Given parameters:

  Number of cell per body = 60 trillion body cells

   Population of the earth = 6 billion

Unknown:

Total number of living human body cells = ?

Solution:

  To solve this problem, simply find the product:

 Total number of living human body cells = number of cell per body x population of the earth

          1 trillion = 1 x 10¹²

         60 trillion = 6 x 10¹³

         1 billion = 1 x 10⁹

         6 billion = 6 x 10⁹

Total number of living human body cells = 6 x 10¹³ x  6 x 10⁹

                                                                      = 6 x 6 x 10⁽¹³⁺⁹⁾

                                                                       = 36 x 10²² or 3.6 x 10²³
