A molecule with the formula ch3ch(nh2)cooh probably exhibit which of the folloiwng characteristics

1 answer:

3 0

Considering the answers;
1)Molecules with this formula would likely be hydrophobic.
2)Polymers of this molecule can serve as storage or structural components. 
3)The side chains of this molecule would determine its function. 
4)This type of molecule serves as a vehicle for transmission of genetic material
The correct answer is; 2) Polymers of this molecule can serve as storage or structural components.
The molecule shown in the question is an amino acid; alanine to be specific.
The molecule is not hydrophobic; The side chain does determine its function, but only in comparison with other amino acids that do not share this formula. Amino acids are not vehicles for genetic material; that's nucleic acids.

Avogadro's Number - 6.022 × 10²³ atoms, molecules, formula units, etc.

<h3>Explanation:</h3>

Step 1: Define

50.0 mol H₂O

Step 2: Identify Conversions

Avogadro's Number

Step 3: Convert

$\displaystyle 50.0 \ mol \ H_2O(\frac{6.022 \cdot 10^{23} \ molecules \ H_2O}{1 \ mol \ H_2O} )$ = 3.011 × 10²⁵ molecules H₂O

Step 4: Check

We are given 3 sig figs. Follow sig fig rules and round.

3.011 × 10²⁵ molecules H₂O ≈ 3.01 × 10²⁵ molecules H₂O

6. What is the wavelength (in meters) of the electromagnetic carrier wave transmitted by The Sports

Vsevolod [243]

Answer:

wavelength = 2.81 m

Explanation:

Given that,

The frequency of the Sports Fan radio station, f = 106.4 MHz

We need to find the wavelength (in meters) of the electromagnetic carrier wave. The relation between frequency and wavelength is given by :

$c=f\lambda$

Where,

$\lambda$ is wavelength

$\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{106.4\times 10^6}\\\\\lambda=2.81\ m$

So, the wavelength of the electromagnetic carrier wave is 2.81 m.

Ordered: 0.3 gm. Available: 300 mg/tablet. How many tablets should be given?

dimulka [17.4K]

Answer:

1 tablet

Explanation:

Assuming that gm stands for gram:

Put everything in one unit, 0.3 g = 300 mg.

And given that each tablet is 300 mg:

mass/amount = 300mg / 1 tablet

300mg / X amount = 300mg / 1 tablet

(300mg/300mg) tablet = X = 1 tablet

So it is 1 tablet you need.
