13. During photosynthesis, carbon dioxide and water combine according to the general

Calculate the compound amount. Use the compound amount formula and a calculator. (Round your answer to two decimal places.) P =

Julli [10]

Answer:

The compound amount is $303.03 .

Explanation:

Formula for compound interest:

$A=P\times (1+\frac{R}{n})^{tn})$

Principle amount = $1100

Rate of the interest compounded semiannually :

= R = 9% = 0.09

Number of times interest compounded, n = $\frac{12}{6}=2$

(semi means two times in a year)

Time period = T = 14

$A=\$1100\times (1+\frac{0.09}{2})^{2\times 14}=\$303.0310\approx \$303.03$

The compound amount is $303.03 .

What does it mean for the energy levels in an atom to be quantized? Describe how this affects where electrons can be found

marta [7]

When we describe the energy of a particle as quantized, we mean that only certain values of energy are allowed. ... In this case, whenever we measure the particle's energy, we will find one of those values. If the particle is measured to have 4 Joules of energy, we also know how much energy the particle can gain or lose. Quantized energy means that the electrons can possess only certain discrete energy values; values between those quantized values are not permitted

<h3>Explanation:</h3>

<u>Step 1: Define</u>

[RxN - Balanced] C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂

[Given] 500. g C₆H₁₂O₆ (Glucose)

[Solve] moles C₂H₅OH (Ethanol)

<u>Step 2: Identify Conversions</u>

[RxN] 1 mol C₆H₁₂O₆ → 2 mol C₂H₅OH

[PT] Molar mass of C - 12.01 g/mol

[PT] Molar Mass of H - 1.01 g/mol

[PT] Molar Mass of O - 16.00 g/mol

Molar Mass of C₆H₁₂O₆ - 6(12.01) + 12(1.01) + 6(16.00) = 180.18 g/mol

<u>Step 3: Stoichiometry</u>

[DA] Set up conversion: $\displaystyle 500 \ g \ C_6H_{12}O_6(\frac{1 \ mol \ C_6H_{12}O_6}{180.18 \ g \ C_6H_{12}O_6})(\frac{2 \ mol \ C_2H_5OH}{1 \ mol \ C_6H_{12}O_6})$
[DA} Multiply/Divide [Cancel out units]: $\displaystyle 5.55001 \ mol \ C_2H_5OH$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

5.55001 mol C₂H₅OH ≈ 5.55 mol C₂H₅OH

2. Why do you think electroplated jewelleries are in demand?<br> Chemistry plsss

Ivan

Explanation:

Electroplated jeweleries are in demand because firstly they are as shiny and attractive as real jeweleries, they are also light weighted and cost effective.
