The correct answer is D. The nucleus and the electron cloud

Explanation:

An atom is the smallest particle that composes all matter in the universe. Atoms are composed of three main sub-particles: neutrons, protons (positively charged), and electrons (negatively charged). Additionally, the neutrons and protons are in the center of the atom and form the nucleus that has a positive charge due to the protons, while the electrons negatively charge are not in the nucleus but orbit as part of electron clouds that surround the nucleus. Thus, the two parts of an atom are the nucleus that contains protons and neutrons and the electron cloud that contains electrons.

carbon dioxide at 25 degrees celsius and 101.3 kpa has a density of 1.799 kg/m^3 determine gas constant
dusya [7]

Answer:

Explanation:

Temperature of gas in absolute scale T = 25 + 273 = 298 .

pressure of gas P = 1.013 x 10⁵ N / m²

density D = 1.799 kg / m³

= 1799 g / m³

From gas formula

PV / T = n R Where P is pressure , V is volume and T is absolute temperature , n is no of moles

P / T = n R / V

P / T = m R /M V where m is mass of gas and M is molecular weight .

m / V = D ( density )

P / T = DR/ M  

PM / DT = R

Putting the values

1.013 x 10⁵ x 44  /  (1799 x 298)

R = 8.314.09 J / K mole
