katrin2010 [14]

Answer:

D. \ \ \ \text{hydroxyl}

Explanation:

Alcohols are organic compounds that are composed of the hydroxyl function group (-\text{OH}), bonded to a carbon atom of an alkyl or a substituted alkyl group. Hence, the functional group of alcohols is the hydroxyl group (-\text{OH}).

According to the International Union of Pure and Applied Chemistry (IUPAC) nomenclature, alcohols are named by changing the -<em>e</em> ending of the name of the parent alkane to the suffix <em>-</em><em>ol</em>.

For example, the alcohol molecule in the figure demonstrates a hydroxyl group bonded to a methyl group. Therefore, the name of the alcohol is methanol.

When a piece of zinc metal is carefully placed in a beaker of strong acid, bubbles form on the surface of the metal and begin to
kati45 [8]

Answer:

A.  a new substance is being produced.

Explanation:

The bubbles most likely indicates that a new substance is being produced by this reaction. In essence, we describe this sort of change as chemical change.

In a chemical change, new substances are usually produced. They are accompanied by the evolution or absorption of energy.

The reaction of Zinc with a strong acid to produce bubbles on the surface of the metal indicates a chemical change and the formation of a new kind of substance.

Take for example, let zinc reacts with hydrocholoric acid, HCl;

   Zn         +      2HCl      →    ZnCl₂     +     H₂

Since Zn is higher than Hydrogen in the activity series, it will displace it from HCl and liberate hydrogen gas as a product. This will cause the bubbles observed in the reaction.

This is a chemical change and new products have been formed.

B and D are wrong because they are both physical changes.

C is wrong because no information about such is provided by the problem statement.

So, when a piece of zinc metal combines with a strong acid, a new kind of substance is produced.

A+gas+at+250k+and+15atm+has+a+molar+volume+12%+less+than+the+perfect+gas+law+character. +calculate+the+compressibility+factor
shutvik [7]

The compression factor based on the information given is 0.083.

<h3>How to calculate the compression factor?</h3>

The way to calculate the compression factor goes this:

V(ideal) = RT/P

= (0.0821 × 250)/15

= 1.368

V(real) will be:

= V(ideal)/12

= 1.368/12 = 0.114

The compression factor will be:

= 1.368/(12 × 1.368)

= 0.083

Therefore, the compression factor is 0.083.

How do you find the atomic weight of an atom?
wariber [46]

Answer: The atomic weight of any atom can be found by multiplying the abundance of an isotope of an element by the atomic mass of the element and then adding the results together. This equation can be used with elements with two or more isotopes: Carbon-12: 0.9889 x 12.0000 = 11.8668. Carbon-13: 0.0111 x 13.0034 = 0.1443.
