The relative atomic mass of chlorine is 35.5.
When calculating relative atomic mass, which particle is the mass of a chlorine atom compared
to?

Answers

Given what we know, we can confirm that relative atomic mass is calculated by comparing the particles to the atomic mass of a carbon-12 atom.

Why compare to carbon-12?Carbon is a very common element. It was been studied greatly, telling us a great deal about the atom. It contains 6 protons and 6 neutrons.This makes it very stable and the standard for comparison.

Therefore, given its abundant nature and the fact that it has been extensively studied, we can confirm that a carbon 12 atom has exactly 6 protons and 6 neutrons, making it very stable and the standard to which other atoms are compared.

A watch loses 0.15 sec/min, how many seconds are lost in 24 hours?

Answers

Answer:  

0.15 sec/min = 9 sec/hour

9*24 = 216 seconds = 3.6 minutes

Explanation:

Answer:

216 Seconds

Explanation:

If every minute is 60 seconds than 60 multiplied by .15 is 9 Seconds Lost.

If every hour is 60 minutes compared to what we know than 24 hours multiplied by 60 is 1440 minutes.

Do the same math as before: 1440 x .15 = 216 Seconds

can the following alcohol be prepared as a single product by hydroboration-oxidation of an alkene? can it be prepared as a single product by the acid-catalyzed addition of h2o to an alkene? select the single best answer.

Answers

Answer:

Yes both methods give a single product.

Explanation:

The answer can be Yes, both the methods will yield a single product. The correct option is D.

What is alcohol formation?

Alcohols can be made by hydrating alkenes or reducing aldehydes, ketones, acids, and esters. Water elements can be added to an alkene's doublebonded carbons in either a Markovnikov's or an antiMarkovnikov's manner.

When yeast ferments the sugars in grains, fruits, and vegetables, it produces it. For example, wine is made from grape sugar, and vodka is made from potato sugar.

In the presence of a catalyst, lower molecular weight olefins react with carbon monoxide and hydrogen in a reaction known as hydroformylation or the oxo reaction. The resulting aldehyde is then hydrogenated to produce alcohol.

Thus, the correct option is D.

An unknown substance dissolves in water but separates and floats in oil.

Answers

Answer:

Any polar substance

Explanation:

We know that non polar substances wont dissolve in water because they do not react properly with water molecules, any polar substance would dissolve in water and float in oil.

An unknown substance dissolves in water but separates and floats in oil is any polar substance.

What are polar substances?

Polar substance are defined as those whose bonding with atoms like nitrogen, oxygen, or sulfur has resulted in discrete positive and negative charge areas.

It can also be defined as an electrical pole is typically created when a molecule has more positive charges on one end than negative charges on the other, forming an electrical pole.

Non polar substances are defined as a molecule that lacks charges at the ends because its electrons are evenly distributed and those that cancel one another out symmetrically.

It is can also be defined as in covalent compounds, there is no change in electronegativity.

Thus, an unknown substance dissolves in water but separates and floats in oil is any polar substance.

What is buffer system ?

When acids or bases are introduced, a buffer system is a solution that resists changing in pH. Acidic solutions have pH values under seven and significant hydrogen ion ( H+ ) concentrations. Basic solutions have pH values higher than seven and high quantities of hydroxide ions ( OH- ).

The carbonate, carbonic acid buffer, the phosphate buffer, and the buffering of plasma proteins make up the body's chemical buffer system.

Plasma proteins, phosphate, bicarbonate, and carbonic acid buffers are among the buffer systems active in blood plasma. By excreting hydrogen ions and producing bicarbonate, which helps keep blood plasma pH within a normal range, the kidneys contribute to the regulation of acid-base balance.

Thus, option A is correct.

Oxidation reaction

The kind of reaction involving the transfer of electrons or hydrogen away from a molecule is called oxidation.

In the same vein, the molecule that receives the electron or the hydrogen atom is said to be reduced. This means that oxidation cannot exist in isolation without reduction.

Answer:

[tex]\boxed {\boxed {\sf 600 \ kg/m^3}}[/tex]

Explanation:

We are asked to find the density of a bowling ball. The density of an object is its mass per unit volume. It is calculated by dividing the mass by the volume.

[tex]\rho= \frac{m}{v}[/tex]

The mass of the bowling ball is 3.0 kilograms and the volume is 0.0050 cubic meters.

m= 3.0 kg v= 0.0050 m³

Substitute the values into the formula.

[tex]\rho= \frac{3.0 \ kg}{0.0050 \ m^3}[/tex]

Divide.

[tex]\rho= 600 \ kg/m^3[/tex]

The density of the bowling ball is 600 kilograms per cubic meter.

What types of bonds, and how many bonds, do you predict arsenic form with other elements?

Answers

Answer:

The outer-shell similarity of the two elements suggests that arsenic, like phosphorus, can form three covalent bonds per atom, with an additional lone pair of electrons left unbonded.

Atomic number: 96

Oxidation states: +3, +4

Arsenic atom can form either three or five bonds in arsenic compounds.

The number of bonds that an element will form to other elements depends on the number of electrons on the valence shell of that element. Arsenic has five valence electrons on its valence shell.

We know that there is one lone pair on the valence shell of arsenic hence, the arsenic atom can form either three or five bonds in arsenic compounds.

In conclusion, arsenic is an element that could form three or five bonds in its compounds.
