Answer:

amino acids

Explanation:

The building blocks of proteins are amino acids. Two amino acids join with each other with a peptide bond and the release of one molecule of water. This is known as condensation reaction. Amino acids join with each other to form peptides. Peptide chains arrange in 3D conformation to form a protein macromolecule.

Which of the following would be considered a compound?<br> He<br> CI<br> NaCl<br> B
kobusy [5.1K]

Answer:

NaCl

Explanation:

because He which is helium gas its an element alone,

Cl which is chlorine is a single element,

B which is Boron and its a single element,

but NaCl which is simply called table sugar is the combination between Na, sodium and Cl, chlorine , so its called a compound not an element.

Which of the following is a unit of density? = Mass / volume
krok68 [10]

Answer:

The correct answer is C.

Explanation:

To solve this problem, we should first recall possible units for mass and volume.  Mass can be represented with units of grams, kilograms, etc.  Volume has units of cubic meters, cubic centimeters, etc.

Therefore, since we know that density is mass divided by volume, the only answer that makes sense here is C. grams per cubic centimeter (where per signifies that grams are being divided by cubic centimeters).

Hope this helps!

Oxygen gas, generated by the reaction 2KClO3(s)-&gt;2KCl(s)+3O2(g) is collected over water at 27°C in a 1.55 L vessel at a total
KonstantinChe [14]

Answer:

Explanation:

Use Dalton's law and the vapor pressure of water at 23.0 o C to correct the pressure to units of atmoshperes.

PT = Poxygen +Pwater

At 23.0 o C the vapor pressure of water is 21.1 mmHg. (This can be found on a vapor pressure table.)

762 mmHg = Poxygen + 21.1 mmHg

Poxygen = 762 mmHg - 21.1 mmHg

Poxygen =741 mmHg

Convert the corrected pressure to atmospheres.

(741 mmHg) (1 atm / 760 mmHg) = 0.975 atm

Use the ideal gas law to find out how many moles of gas were produced:

PV = nRT (remember to put volume in liters and temperature in Kelvin)

(0.975 atm) (.193 L) = n (.0821 L atm / mol K) (298 K)

n = (0.975 atm) (.193 L) / (.0821 L atm / mol K) (298 K)

n = 7.69 X 10-4 mol

Use the number of moles and the molecular weight of oxygen to find out how many grams of oxygen were collected.

(7.69 X 10-4 mol) (32.0 g / 1 mol) = 2.46 X 10-2 g

What is the empirical formula of a substance that contains 2.64 g of c, 0.444 g of h, and 7.04 g of o?
vitfil [10]

To calculate empirical formula, number of moles of different atoms calculated first:

Number of moles of Carbon , n=  

=\frac{Given mass of carbon}{Molar mass of carbon}

=\frac{2.64 g}{12.011 g mol^{-1}}

= 0.220 mol  

Number of moles H =\frac{Given mass of hydrogen}{Molar mass of hydrogen}

=\frac{0.444 g}{1.008 g mol^{-1}}

= 0.440 mol

Number of moles of oxygen =\frac{Given mass of oxygen}{Molar mass of oxygen}

=\frac{7.04 g}{15.999 g mol^{-1}}

= 0.440 mol

Ratio of carbon

=\frac{0.220}{0.220}

= 1

Ratio of hydrogen

=\frac{0.440}{0.220}

= 2  

Ratio of oxygen

=\frac{0.440}{0.220}

= 2  

So, the empirical formula is CH₂O₂
