The given substance is SOLID. Solids have definite shape and definite volume. By the term definite we mean that wherever it may be placed both shape and volume remain the same. From the given above, the substance has a definite shape of sphere and definite volume of 50 mL.

Assign each species to the expression that most accurately describes the basic units of that substance. categories: single atoms
Temka [501]
Atoms are the smallest form of the substance. examples of atoms are in elemental forms such as copper, helium, silver. Diatomic molecules are made up of identical atoms. Examples are I2.. F2 and Br2. Formula units are those compounds that are made up of two or more elements such as -No2, KMnO4,<span>C3H8, MgCl2, HgBr2, Ba(OH)2</span>

A standard soft drink can has a volume of 0.355 L. An empty can is sealed while
beks73 [17]

Answer:

0.35 atm

Explanation:

To solve this problem, we use Boyle's Law: P_1V_1=P_2V_2 , where P is the pressure and V is the volume.

Here, V_1 = 0.355 L, P_1 = 1.0 atm, and V_2 = 0.125 L. So, just plug these values into the equation:

(1.0) * (0.355) = P_2 * (0.125)  ⇒  P_2 ≈ 0.35 atm

Thus, the pressure is 0.35 atm.

Hope this helps!

What is the change in density if a sample goes from 3.21 g/L to 5.43 g/mL?
Step2247 [10]

Answer:

\Delta \rho =2.22 g/mL

Explanation:

Hello,

In this case, since a change in science is widely known to be considered as a subtraction between the the final and initial values of two measured variables and is represented via Δ, here the final density is 5.43 g/mL and the initial one was 3.21 g/mL, therefore, the change in density is:

\Delta \rho=\rho _f-\rho _i\\ \\\Delta \rho=5.43g/mL-3.21g/mL\\\\\Delta \rho =2.22 g/mL

Best regards.
