How many moles of NaOH are in a 75.89g sample? (mass= 40.01 g) (Show your work)
Answers
Answer:
1.896 moles of NaOH-----> 1.90 moles
Explanation:
Written- out Method:75.89 g of NaOH | 1 mole of NaOH
| 40.01 g NaOH = 1.896 -----> 1.90 moles of NaOH
Plug into calculator method:(75.89 g NaOH/ 40.01 g NaOH = 1.896 -----> 1.90 moles of NaOH
Why don’t all salts make a one-to-one ratio?
Answers
Answer:
because all types of salts are made up of different substrances
All salts do not make a one-to-one ratio because the salts are composed of different ions that combine together in different ratios.
A salt is an ionic substance. Salts are formed by combination of a cation and and anion.
Different salts are comprised of different ions. The ratios in which the ions combine in each salt is not the same.
Hence, all salts do not make a one-to-one ratio because the salts are composed of different ions that combine together in different ratios.

Answers
The question is incomplete, the complete question is shown in the image attached.
Answer:
1) No, it has the right number of valence electrons but does not satisfy the octet rule.
2) Yes
3) No, it has the wrong number of valence electrons, the correct number is 16
Explanation:
If we look at the first structure in the image(HCN), it easy to see from inspection that nitrogen has three valence electrons as it is normally supposed to have. However, if we count all the electrons around nitrogen, we will notice that they are six instead of eight. Thus nitrogen has not satisfied the octet rule here.
The structure HBr satisfies the octet rule, hence it is a reasonable Lewis structures for the compound shown.
CO2 has 16 valence electrons but the structure shown contains about 20 valence electrons hence it is not a reasonable Lewis structure for the compound.
Yes, in HCO⁺ the proposed lewis structure is reasonable.
No, COCl₂ has the wrong number of valence electrons.
No, OH⁻ has the right valence electron but does not obey the octet rule.
The correct structure for the question can be seen in the image attached below.
In the proposed structure, the number of valence electrons in HCO⁺ is: ( 1 + 4 + (6-1) ) = 10e⁻Thus, the atoms obey the octet rule and the number of calculated valence electrons corresponds with what we have in the given structure.
Yes, the structure is correct and reasonable.
In COCl₂, the central carbon bonding to the oxygen is supposed to be doubly bonded and not singly bonded.the number of valence electron in COCl₂ is: ( 4 + 6 + (7 × 2)) = 24e⁻The calculated number of valence electrons is different from the given structure of 26e⁻, so we can say No, it has a wrong number of valence electrons.
In the third structure, oxygen is supposed to have three lone pairs of electrons in order to obey the octet rule.the number of valence electrons in the structure is: (6 + (1+1) = 8e⁻
But both H, as well as, O do not obey the octet rule. Therefore, we say No, it has the right number of valence electron but do not obey the octet rule.

Answer:
Your friend gave the better response
Explanation:
Formula for density:
Density = mass/volume
p = m/v
Let's substitute the given values into the equation:
p = m/v
p = 23.2/8.593
Solve:
p = 23.2/8.593
p = 2.69987198883
2.69987198883 grams per volume
Notice that 2.69987198883 is the exact answer. Your answer is 2.67, which is inaccurate, even if rounded. If you were to round the exact answer to the nearest hundredth, it would be 2.70 which is not 2.67.
Therefore, your friend gave the better response because it is the correct answer.
density equals mass over volume
23.2/8.593 = 2.69 g/mL
Jose adds five grams of a chemical to one liter of liquid and observes a reaction. If the reaction is endothermic, what will happen?
A
The liquid's mass increases; therefore, the volume of the liquid will increase
B
The liquids' mass decreases; therefore, the volume of the liquid will decrease.
С
Energy is released during the reaction; therefore, the temperature of the liquid will increase.
Energy is absorbed during the reaction; therefore, the temperature of the liquid will decrease.
D
Answers
Answer:
D. Energy is absorbed during the reaction; therefore, the temperature of the liquid will decrease
Explanation:
In a chemical reaction, the reaction is said to be ENDOTHERMIC if the reaction utilizes or uses energy instead of given it off. In this reaction, Jose adds five grams of a chemical to one liter of liquid and observes the reaction.
According to this question, the reaction is ENDOTHERMIC. This means that energy is absorbed or used up during the reaction; therefore, the temperature of the liquid will decrease i.e. the liquid used in the reaction will become COLDER.

Answers
Answer:
Explanation:
Latent heat of fusion of zinc = 7.322 kJ / mol
molecular weight of zinc = 65 g
450 gram = 450 / 65 = 6.92 mole
Heat required to melt 450 g of zinc = 6.92 x 7.322 kJ
= 50.67 kJ .
= 50.7 kJ .

Owing to the electronic configuration of metals ,metallic bonding exists in metals because of which when light is pointed at them they become shiny.
What is electronic configuration?Electronic configuration is defined as the distribution of electrons which are present in an atom or molecule in atomic or molecular orbitals.It describes how each electron moves independently in an orbital.
Knowledge of electronic configuration is necessary for understanding the structure of periodic table.It helps in understanding the chemical properties of elements.
Elements undergo chemical reactions in order to achieve stability. Main group elements obey the octet rule in their electronic configuration while the transition elements follow the 18 electron rule. Noble elements have valence shell complete in ground state and hence are said to be stable.
