scenario Juan and Maria Lopez wish to invest in a no-risk savings account. They currently have 530,000 in an account bearing 5.25 % annual interest, compounded continuously. The following options are available to them.
Answer:
The amount after three year is 617934.1302
Explanation:
Complete question
A person places $530,000 in an investment account earning an annual rate of 5.25%, compounded continuously. Using the formula V = Pe^{rt}V=Pe rt , where V is the value of the account in t years, P is the principal initially invested, e is the base of a natural logarithm, and r is the rate of interest, determine the amount of money, to the nearest cent, in the account after 3 years
Solution
The formula for calculating compound interest is
[tex]A = p (1 + \frac{r}{n})^{nt}[/tex]
Substituting the given values we get -
[tex]A = 530,000 (1 + \frac{5.25}{100})^3\\A = 530,000 * ( 1+ 0.0525)^3\\A = 530,000 * ( 1.0525)^3\\A = 617934.1302[/tex]
The amount after three year is 617934.1302

When an acetic acid solution is titrated with sodium hydroxide, the slope of the titration curve (pH versus volume of NaOH added) increases when sodium hydroxide is first added. This change shows that ________
Answer:
When an acetic acid solution is titrated with sodium hydroxide, the slope of the titration curve (pH versus volume of NaOH added) increases when sodium hydroxide is first added. This change shows that acetic acid is being converted to sodium acetate.
Explanation:
ABOUT TITRATION - Titration is a chemical analysis method for determining the amount of a constituent in a sample by adding an exact known quantity of another substance to the measured sample with which the desired constituent reacts in a specific, known proportion. A burette, which is essentially a long, graduated measuring tube with a stopcock and a delivery tube at the bottom end, is used to gradually administer a standard solution of titrating reagent, or titrant.
It is feasible to identify a good visual color indicator for many titration processes that will signify the end point at, or very near to, the equivalence point.
Acid-base titrations, precipitation titrations, complex-formation titrations, and oxidation-reduction (redox) titrations are examples of such titrations, which are categorised according to the nature of the chemical reaction that occurs between the sample and the titrant.
Titrations of metal ions with the reagent disodium ethylenediaminetetraacetate are the most important titrations based on complex-formation processes (a salt of edetic acid, or EDTA).
Hence , the answer is that acetic acid is converted into sodium acetate.

A sample of a gas has a volume of 852 mL at 298 K. If the gas is cooled to 200K, what would the new volume be?
Answer:
571.81 mL
Explanation:
Assuming constant pressure, we can solve this problem by using Charles' law, which states that at constant pressure:
V₁T₂=V₂T₁Where in this case:
V₁ = 852 mLT₂ = 200 KV₂ = ?T₁ = 298 KWe input the data:
852 mL * 200 K = V₂ * 298 KAnd solve for V₂:
V₂ = 571.81 mLThe new volume would be 571.81 mL.

By putting the values, we get
⇒ [tex]=\frac{1.5\times 10.0}{0.66}[/tex]
⇒ [tex]=\frac{15}{0.66}[/tex]
⇒ [tex]=22.73\ atm[/tex]
Science- I need help with a question really quick I’m ending school soon
If one neutron initiates a fission event that produces two neutrons in the products, how many new reactions can now be initiated? 9 If each of the neutrons produced in the first fission event then initiates a fission event that produces one neutron in the products, how many new reactions can now be initiated by each neutron? How many neutrons in total were produced by the two fission events described?
Answer:
See Explanation
Explanation:
A fission reaction is a chain reaction. The neutrons that are produced in one reaction leads to further chain reaction in the system.
If one neutron initiates fission that leads to the production of two other neutrons,two more new reactions are initiated.
If these reactions each produce one neutron, then another two new reactions are initiated. This makes a total of four new reactions from the two fission events described.
A total of four neutrons is produced from the two fission events.

I need help with my chemistry but you can oonly choose one option
Answer:
well it is an Synthesis reaction
Explanation:
in the view of the fact that a sodium metal .."Sodium" reacts with an "chloride gas" to form a sodium Chloride. NaCL2NaCl-->2Na+ Cl2
Correct Option- Decomposition
_____________________________
Decomposition reactions are those reactions in which a compound breaks or splits into two or more simpler substances. In such reactions, one reactant breaks down to form many i.e. at least two products. These reactions require energy to break existing bonds, so they take place in the presence of heat, light, or electricity.
Example:- AB--> A+B
Hope This Helps You ❤️If atoms are electrically neutral then how do they form bonds?
Answer:
The nucleus contains neutrons and protons; protons carry the positive charge. The shells contain electrons which carry the negative charge. So, how can the atom be changed. ... Covalent bonds are electrically neutral because they are not formed due to the transfer of electrons but sharing of electrons.Explanation:
Hope it helps ^-^
#CarryOnLearning
Answer:
When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral. ... Chemically, we say that the atoms have formed bonds
A 1.0 kg bottle of sodium carbonate (Na2CO3, 106.0 g/mol) is available to clean up 5.00 liters of spilled concentrated aqueous hydrochloric acid (9.75 M). Is this enough sodium carbonate to neutralize the acid according to the following reaction?
2 HCl (aq) + Na2CO3 (s) 2NaCl (aq) + CO2 (g) + H2O (l)
(1) No, there is approximately 40% too small amount of sodium carbonate needed.
(2) Yes, there is approximately 80% more than what is needed.
(3) No, there is approximately 60% too small amount of sodium carbonate needed.
(4) Yes, there is exactly enough sodium carbonate, but no excess.
(5) No, there is approximately 20% too small amount of sodium carbonate needed.
Answer:
The correct answer is option 4, that is, there is exactly enough sodium carbonate.
Explanation:
Based on the given question, the reaction will be,
2 HCl (aq) + Na2CO3 (s) ⇒ 2 NaCl (aq) + CO2 (g) + H2O (l)
Therefore, for neutralizing 2 moles of HCl, one mole of Na2CO3 is required.
No of moles present in 1 Kg or 1000 grams of Na2CO3 will be,
Moles = Weight/Molecular mass of Na2CO3
Moles = 1000 / 106 = 9.43
Thus, 9.43 moles of Na2CO3 is present.
No of moles present in 1 liter of 9.75 M HCl is 9.75.
No. of moles present in 5 Liters of HCl (9.75 M),
= 5 × 9.75 = 48.75
Thus, for 2 moles of HCl 1 mole of Na2CO3 is required. Now for 48.75 moles of HCl, the moles required of Na2CO3 is 9.75. Therefore, for complete neutralization, the moles of Na2CO3 required is 9.75, and the present moles is 9.43.
Hence, there is exactly enough sodium carbonate.

Given 32.0 g of water, if we see a temperature change from 25.0°C to 20.0°C, then how much heat energy (q) is transferred from the water?
(The specific heat of water is 4.184 J/g°C )
Answer:
Q = 669.44 J
Explanation:
Given that,
Mass of water, m = 32 g
The temperature change from 25.0°C to 20.0°C.
We need to find the amount of heat energy transferred. Let it is Q. We know that,
[tex]Q=mc\Delta T[/tex]
Where
c is the specific heat of water
Put all the values,
[tex]Q=32\times 4.184 \times (20-25)\\Q=669.44\ J[/tex]
So, 669.44 J of heat energy is transferred from the water.

A solution is made by adding 23.1 mL of concentrated nitric acid ( 70.4 wt% , density 1.42 g/mL ) to some water in a volumetric flask, and then adding water to the mark to make exactly 200 mL of solution. Calculate the concentration of this solution in molarity.
Answer:
The correct solution is "3.6975 M".
Explanation:
The given values are:
Volume of solution,
V = 23.2 mL
Density,
D = 1.42 g/mL
Final volume,
= 200 mL
or,
= 0.2 L
Now,
The mass will be:
= [tex]D\times V[/tex]
= [tex]1.42\times 23.1[/tex]
= [tex]32.802 \ g[/tex]
Mass of HNO₃ will be:
= [tex]\frac{32.802}{0.704}[/tex]
= [tex]46.59375 \ g[/tex]
Mol of HNO₃ will be:
= [tex]\frac{mass}{MW}[/tex]
= [tex]\frac{46.59375}{63}[/tex]
= [tex]0.7395 \ mol[/tex]
hence,
The concentration will be:
= [tex]\frac{mol \ of \ HNO_3}{final \ V}[/tex]
= [tex]\frac{0.7395}{0.2}[/tex]
= [tex]3.6975 \ M[/tex]
