A substance composed of two or more elements chemically combined in a definite, fixed proportion by mass is a Compound

A compound is a fabric composed of two or greater components. Water, carbon dioxide and desk salt are a few examples of compounds.

Compound A substance including atoms or ions of two or extra extraordinary factors in precise proportions joined with the aid of chemical bonds into a molecule. The factors can not be separated by means of bodily approach. Water, as an instance, is a compound having  hydrogen atoms and one oxygen atom according to molecule.

Milk isn't compound. A compound is an entity which includes  or greater distinctive atoms associating with chemical bonds. Milk is an emulsion or colloid of fats globules within a water-primarily based fluid that consists of dissolved carbohydrates and protein aggregates with minerals.

A compound contains atoms of various elements chemically blended together in a fixed ratio. An detail is a pure chemical substance made of same type of atom. Composition. Compounds include one-of-a-kind factors in a fixed ratio arranged in a described manner via chemical bonds.

Compounds shape as a result of chemical reactions. The factors in compounds are held together with the aid of chemical bonds. A chemical bond is a pressure of appeal among atoms or ions that proportion or switch valence electrons. Water is an instance of a commonplace chemical compound.

Ira Lisetskai [31]

Answer:

2.11\ * 10^{-2}  is the correct answer to the given question.

Explanation:

Given k=6.40 x 10-3 min-1.

According to the first order reaction .

The concentration of time can be written as

[\ A\ ]\ = \ [\  A_{0}\ ]  * e \ ^\  {-kt}

Here [\ A\ ]_{0} = Initial concentration.

So  [\ A\ ]_{0}= 0.0314 M

Putting this value into the above equation.

0.0314 \ *\ e^{6.40 x 10^{-3} \ *  \ 62.0  }

=0.211 M

This can be written as

=\ 2.11 *\ 10^{-2}

What is the mass of 3.2 moles of h2O ?
Arturiano [62]

Answer:

\boxed{\text{57.7 g} }

Explanation:

The first step is to calculate the molar mass of H₂O:

\begin{array}{rcr}\text{2 H} & = & 2.02\\\text{1 O} & = & 16.00\\\text{TOTAL} & = & \mathbf{18.02}\\\end{array}

So, 1 mol has a mass of 18.02 g.

Next you calculate the mass of 3.2 mol of H₂O

\begin{array}{rcl}m & = & \text{3.2 mol H$_{2}$O} \times \dfrac{\text{18.02 g H$_{2}$O}}{\text{1 mol H$_{2}$O}}\\ & = &\boxed{\textbf{57.7 g H$_{2}$O}} \\\end{array}
