Name two methods that can be used to break down compounds into simpler substance
kotykmax [81]
<span>Photolysis and hydrolysis. These are two methods that can be used to break down a compound into simpler substances and smaller units.

Water which is used to break the bonds of molecules and split molecules is used from hydrolysis. Hydrolysis is made of three types which include;
1. salt hydrolysis.
2. acid hydrolysis.
3. Base hydrolysis.
 Photolysis is well known to use energy from light to split the molecule and the same energy is referred to as photons which are used to break builds of molecules.</span>

Immunoglobulin G (IgG), formerly called gamma globulin, is a principal antibody in blood serum. A 0.470 g sample of immunoglobul
Nookie1986 [14]

The molecular mass of the immunoglobulin G, given the data from the question is 1.53×10⁵ g/mole

<h3>How to determine the molarity</h3>

We'll begin by calculating the molarity of the immunoglobulin G. This is illustrated below:

  • Volume = 0.106 L
  • Temperature (T) = 25 °C = 25 + 273 = 298 K
  • Osmotic pressure (π) = 0.733 mbar = 0.733 × 0.000987 = 0.00072 atm
  • Gas constant (R) = 0.0821 atm.L/Kmol
  • Van't Hoff factor (i) = 1
  • Molarity (M)

π = iMRT

M = π / iRT

M = 0.00072 / (1 × 0.0821 × 298)

M = 0.000029 M

<h3>How to determine the mole of immunoglobulin G</h3>
  • Molarity = 0.000029 M
  • Volume = 0.106 L
  • Mole =?

Mole = Molarity × volume

Mole = 0.000029 × 0.106

Mole = 3.074×10⁻⁶ mole

<h3>How to determine the molar mass of mmunoglobulin G</h3>
  • Mole = 3.074×10⁻⁶ mole
  • Mass = 0.470 g
  • Molar mass =?

Molar mass = mass / mole

Molar mass = 0.47 / 3.074×10⁻⁶

Molar mass = 1.53×10⁵ g/mole

What is the % by volume of 50mL of ethylene glycol dissolved in 950mL of H2O?
MariettaO [177]

Answer:

5.0 %

Explanation:

Given data

  • Volume of ethylene glycol (solute): 50 mL
  • Volume of water (solvent): 950 mL

Step 1: Calculate the volume of solution

If we assume that <em>the volumes are additive</em>, the volume of the solution is equal to the sum of the volume of the solute and the solvent.

V = 50 mL + 950 mL = 1000 mL

Step 2: Calculate the percent by volume

We will use the following expression.

\% v/v = \frac{volume\ of\ solute}{volume\ of\ solution} \times 100 \%  = \frac{50mL}{1000mL} \times 100 \% = 5.0\%

Can someone please look at this?
Alex Ar [27]

Answer:

\large \boxed{\text{110 mmHg}}}

Explanation:

We can use Dalton's Law of Partial Pressures:

Each gas in a mixture of gases exerts its pressure separately from the other gases.

In other words, if a gas makes up 3.0 % of the atmosphere, its partial pressure is 3.0 % of the total pressure.

p_{\text{N}_{2}} = p_{\text{tot}} \times \dfrac{\text{3.0 parts N}_{2}}{\text{100 parts atmosphere}}= \text{3700 mmHg} \times \dfrac{\text{3.0 mmHg}}{\text{100 mmHg}} = \textbf{110 mmHg}\\\\p_{\text{N}_{2}} = \large \boxed{\textbf{110 mmHg}}
