The amount of a substance can be converted into grams of that substance by using the molar mass. It is a physical property of a substance which describes the mass per mole of the substance. The molar mass of Zn is 65.38 g/ mol. Multiplying the given amount of Zn with the molar mass will yield to the mass of the substance.

1.0 x 10^-3 x 65.38 = 0.0654 g Zn

6.54x10^{-2}gZn

Explanation:

Hello,

By applying the following mole-mass relationship, one could compute the mass of the given moles of Zn:

This is attained by considering that in 1 mol of Zn there are 65.409 g of Zn.

Best regards.

Question
Two species of frog mate in the same pond. One breeds in early summer and one in late summer. This is an example of what kind of reproductive isolation? A. pre-zygotic, behavioral isolation B. pre-zygotic, temporal separation C. pre-zygotic, ecological separation D. post-zygotic, temporal separation E. post-zygotic, ecological separation
Solution 1

Pre-zygotic, temporal separation

Explanation:

Reproductive isolation mechanism is of two types:

• Prezygotic mechanism
• Postzygotic mechanism

Prezygotic mechanism isolation occurs before fertilization and helpful in preventing formation of fertile offspring.

In frog external fertilization occurs. In the external fertilization, eggs and sperms are released in water and fertilization occur outside the water.

Prezygotic isolating mechanisms may include behavioral isolation, temporal isolation, mechanical isolation, gametic isolation and habitat isolation.

Temporal separation in reproduction is the sexual activity in the same geographical range but in different periods.

Therefore, the given reproductive isolation is pre-zygotic, temporal separation.

Question
Which factor is most important to consider when evaluating a journal article about global warming?
Solution 1
Since you didn't include the options, I will answer the question as well as I can: the one factor I would be considering is whether the journal is known to be biased, for example whether it's a peer-reviewed journal ( those are less biased) or whether they journal is paid by some interest group.

Otherwise I would look at whether the data is reliable, for example whether  the author cites the sources for their data
Solution 2

Does the article contain facts or only opinions?

Question
A laboratory analysis of a sample finds it is composed of 38.8% carbon, 16.2% hydrogen, and 45.1% nitrogen. What is its empirical formula? Give your answer in the form C#H#N#, where the number following the element’s symbol corresponds to the subscript in the formula.
Solution 1

Answer: The empirical formula for the given compound is

Explanation : Given,

Percentage of C = 38.8 %

Percentage of H = 16.2 %

Percentage of N = 45.1 %

Let the mass of compound be 100 g. So, percentages given are taken as mass.

Mass of C = 38.8 g

Mass of H = 16.2 g

Mass of N = 45.4 g

To formulate the empirical formula, we need to follow some steps:

Step 1: Converting the given masses into moles.

Moles of Carbon =

Moles of Hydrogen =

Moles of Nitrogen =

Step 2: Calculating the mole ratio of the given elements.

For the mole ratio, we divide each value of the moles by the smallest number of moles calculated which is 3.23 moles.

For Carbon =

For Hydrogen  =

For Oxygen  =

Step 3: Taking the mole ratio as their subscripts.

The ratio of C : H : N = 1 : 5 : 1

Hence, the empirical formula for the given compound is

Question
How many oxygen atoms are in 17.63 grams of co2?
Solution 1
CO₂ = 12 + 2*16 = 44 g/mol

1 mole of CO₂ contain an Avogadro number of molecules of CO₂

44g of CO₂  contain 6.02 * 10²³ molecules of CO₂

17.63g of CO₂ will contain:
17.63 * 6.02 * 10²³ /44

≈ 2.412 * 10²³ molecules of CO₂

Note: 1 molecule of CO₂ has 2 atoms of O

2.412 * 10²³ molecules of CO₂ will have 2.412 * 10²³ * 2 = 4.824 * 10²³ atoms of O.

4.824 * 10²³ atoms of O.
Question
What happens when a catalyst is used in a chemical reaction?
Solution 1
It's speeds up the process
Question
What overall effect does adding a catalyst have on a chemical reaction?
Solution 1

The overall effect of a catalyst to the reaction is that it lowers the activation energy of a chemical reaction. Catalyst is a substance that speeds a chemical reaction. It is not consumed as the reaction proceeds. A catalyst offers a new route for faster reaction.

Solution 2

Explanation:

A catalyst is a specie which makes the rate of reaction faster without itself getting consumed into the chemical reaction.

A catalyst decrease the activation energy barrier for the chemical reaction so that, reactant molecules with low energy can easily participate into the reaction.

Hence, product formation becomes faster.

Therefore, overall effect of adding a catalyst will have an increase in formation of products.

Question
Which type of bond makes it possible for a macromolecule to interact with great specificity with just one out of the many thousands of different molecules present inside a cell? A. Covalent bonds B. Noncovalent bonds C. Hydrogen bonds D. Ionic bonds
Solution 1

Explanation: The non covalent interactions can be defined as the interaction among molecules based on the variation among the electromagnetic radiations.

These molecules are not attached to each other based on the sharing of the electrons.

These interactions are Van der Waals, electrostatic, hydrophobic interactions.

The interaction among the molecules is important in order to maintain the three dimensional structure of compound such as carbohydrates and protein molecules.

Question
which of these solutions has the lowest freezing point? 0.25 m nacl 0.5 m nacl 1.0 m nacl 1.5 m nacl 2.0 m nacl
Solution 1

Colligative properties depend on the amount of solute dissolved in a solvent. These set of properties do not depend on the type of species present. These properties include freezing point depression, boiling point elevation, osmotic pressure and vapor pressure lowering. The correct answer is the last option. The solution which has the highest amount of solute or the 2.0 m NaCl solution will have lower freezing point than the other given choices.

Question
Sodium is a silvery-white metal that reacts with chlorine gas, which is a yellow-greenish gas that is toxic. The reaction gives off a lot of heat. After the reaction, which statement is true about the chemical properties of the product, sodium chloride?
Solution 1

Sodium is a silvery-white metal that reacts with chlorine gas, which is a yellow-greenish gas that is toxic. The  reaction gives off a lot of heat. After the reaction, which statement is true about the chemical properties of the product, sodium chloride?

Pure sodium reacts violently and sometimes explosively with water producing sodium hydroxide, hydrogen gas and heat

2Na(s) + 2H2O(l) → 2NaOH(aq) + H2(g)

Chlorine is a very poisonous yellow green gas with a sharp odour that was used in gas warfare during WW1

Sodium and chlorine reacts with each other, however, to produce one of the most familiar substance used in cooking and preservation industry today Sodium Chloride or Common salt or table salt in the irreversible equation;

2Na(s) + Cl2(g) → 2NaCl(s)

Explanation:

It is easy to see why this reaction takes place so readily sodium has one electron in its outermost valence shell while chlorine has seven electrons in its valence shell. when sodium atom transfers one electron to chlorine atom forming a sodium cation (Na+) and a chloride anion (Cl-) both ions have complete valence shells and are energetically more stable. the reaction is extremely exothermic, producing a bright yellow light and a great deal of heat and fumes of sodium chloride.

In a reaction observation of the reaction process you will see sodium flares up almost immediately upon reaction with water.
