An expensive vacuum system can achieve a pressure as low as 1.00 × 10 − 8 N / m 2 at 19.5 °C . How many atoms are there in a cub
Stels [109]

Answer:

2475042

Explanation:

P = Pressure = [/tex]1\times 10^{-8}\ N/m^2[/tex]

V = Volume = 1 cm³

T = Temperature = 19.5 °C

R = Gas constant = 8.341 J/mol K

N_A = Avogadro's number = 6.022\times 10^{23}

n = Amount of substance

From ideal gas law we have

PV=nRT\\\Rightarrow n=\frac{PV}{RT}\\\Rightarrow n=\frac{1\times 10^{-8}\times 1\times 10^{-6}}{8.314(273.15+19.5)}\\\Rightarrow n=4.11\times 10^{-18}

Number of atoms is given by

n\times N_A\\ =4.11\times 10^{-18}\times 6.022\times 10^{23}\\ =2475042\ atoms

The number of atoms in this vacuum is 2475042

Chocolate milk contains more than one type of component. Therefore, it 1 point
crimeas [40]

Answer:

Homogeneous.

Explanation:

Mixture can be defined as a combination of two or more substances present in varied proportion where each materials are distinct and visibly seen by naked eyes.

In Science, there are two (2) main types of mixture and these are;

I. A homogeneous mixture: it can be defined as any liquid, solid or gaseous mixture which has an identical or uniform composition and properties throughout any given sample of the mixture. In Chemistry, all solutions are considered to be a homogeneous mixture. For example, aqueous hydrogen chloride is a homogeneous mixture of water and hydrogen chloride.

II. A heterogenous mixture: it can be defined as any mixture which has a different or non-uniform composition and properties throughout any given sample of the mixture. This ultimately implies that, the constituents of a heterogenous mixture always remain separate in the sample and as such comprises of two or more phases.

Since the chocolate milk contains more than one type of component. Therefore, it is not a homogeneous substance but a heterogenous substance.

PLEASE HELP ASAP!!! THANKS!<br><br> how do stars and planets effect eachother?
Serhud [2]

Answer:

"Planets May Affect the Chemistry of Their Stars. Planets are, by and large, at the mercy of their stars. Not only do stars provide a ready energy source of radiated light and heat, but the mass and gravitational pull of stars flat-out dwarfs the summed masses and pulls of any orbiting companions."
