As shown in the illustration, a starfish has the shape of a pentagon. Look at the illustration of the fruit. How many sides does this polygon have? ​   ​

Which of the following does not represent the concept of surface area? ​

Find the surface area of a cube with dimensions: s = 5.5 mm. ​

The area of a circle is 182 ft 2. Find its radius.  

A sample of solid sodium bicarbonate, NaHCO3,  is placed in a closed 1.0 L vessel at 398 K and allowed to decompose unil it reaches equilibrium according to the following equation:                                         2 NaHCO3 (s)   ⇌  Na2CO3(s) +  H2O (g)   +  CO (g)      Kp = 0.250 What is the partial pressure of CO (in atm)  at equilibrium?

Consider the reaction of elemental bromine with elemental chlorine to form a bromochloride compound at a given temperature:                                          Br2(g)  +  Cl2(g)   ⇌   2 BrCl(g)       KP = 81.0 A closed vessel is charged with 1.20 atm of Br2(g) and 1.20 atm of Cl2(g) initially and allowed to reach equilibrium. What is the partial pressure of the BrCl (in atm) at that equilibrium? Hint: BrCl has a coefficient of 2. 

Consider the decomposition of bromochloride to produce elemental bromine and elemental chlorine at a particular temperature:                                        2 BrCl(g)   ⇌   Br2(g)  +  Cl2(g)         KP = 81.0 A closed vessel is charged with 1.20 atm of BrCl initially and allowed to reach equilibrium. What is the partial pressure of the Br2 (in atm) at that equilibrium?

A sample of solid sodium bicarbonate, NaHCO3, is placed in a closed 1.0 L vessel at 398 K and allowed to decompose until it reaches equilibrium according to the following equation:                                         2 NaHCO3 (s)   ⇌  Na2CO3(s) +  H2O (g)   +  CO (g)      Kp = 0.650 What is the partial pressure of CO (in atm)  at equilibrium?

Comprises the skin, hair, nails, and glands. It serves as a protective barrier against external threats, regulates body temperature, and houses sensory receptors for touch, pain, and pressure.

comprises glands, such as the pituitary, thyroid, adrenal, and reproductive glands. It produces hormones that regulate bodily functions, including growth, metabolism, reproduction, and development.
