Answer:

Respiration happens in the cells of plants, animals and humans, mainly inside mitochondria, which are located in a cell's cytoplasm. The energy released during respiration is used by plants to make amino acids, and by animals and humans to contract their muscles to let them move.

The air in a 4.00 L tank has a pressure of 1.20 atm . What is the final pressure, in atmospheres, when the air is placed in tank

stellarik [79]

Answer:

P₂ = 1.92 atm

Explanation:

According to the boyle's law:

The pressure of given amount of gas at constant temperature and number of moles of gas is inversely proportional to the volume.

P₁V₁= P₂V₂

Given data:

Initial volume = 4.00 L

Initial pressure = 1.20 atm

Final volume = 2500 mL

Final pressure = ?

Solution:

First of all we will convert the volume into litter.

2500 mL × 1L/1000 mL = 2.5 L

P₁V₁ = P₂V₂

P₂ = P₁V₁ /V₂

1.20 atm×4.00 L = P₂ ×2.5 L

P₂ = 1.20 atm×4.00 L/ 2.5 L

P₂ = 4.8 atm. L/ 2.5 L

P₂ = 1.92 atm

Cubes are three-dimensional square shapes that have equal sides. What is the density of a cube that has a mass of 12.6 g and a m

ratelena [41]

Answer:

A. 0.1828 g/cm³

Explanation:

Hi there,

Density's well known formula is Greek letter rho: ρ $=\frac{m}{V}= \frac{m}{a^3}$ where m is the mass, and V is volume. Since the volume in question is a cube, the volume of a cube is simply the edge length $V =$ $a$ ³

$V = (4.1 cm)$ ³ = 68.921 cm³

ρ $= \frac{12.6 g}{68.921 cm^3}$ = 0.1828 g/cm³

Thanks,
