Answer:
P₂ = 0.6406 atm
Explanation:
Given data:
Initial volume = 24.0 L
Initial pressure = 1.00 atm
Initial temperature = 203.0 K
Final temperature = 298.0 K
Final volume = 55.0 L
Final pressure = ?
Solution:
According to general gas equation:
P₁V₁/T₁ = P₂V₂/T₂
Formula:
P₁V₁/T₁ = P₂V₂/T₂
P₁ = Initial pressure
V₁ = Initial volume
T₁ = Initial temperature
P₂ = Final pressure
V₂ = Final volume
T₂ = Final temperature
Solution:
P₂ = P₁V₁ T₂/ T₁ V₂
P₂ = 1 atm × 24.0 L × 298.0 K / 203.0 K × 55.0 L
P₂ = 7152 atm .L. K / 11165 K.L
P₂ = 0.6406 atm
When we multiply or divide the values the number of significant figures must be equal to the less number of significant figures in given value.
Thus we will include four significant figures in answer because 7152 have four significant figure.
The community with high blood varsity is represented with species richness
<h3>What is a community with high biodiversity?</h3>
A community with high biodiversity means that a region supports a wide variety of species, while low biodiversity implies that an area supports only a few. The reasons for variances in biodiversity are complex, but they include both natural and man-made causes.
The number of species per unit area is called Species Richness. If you have more number of species , more will be species richness hence stable will be the ecosystem. More species richness will contribute to increase in biodiversity also which is an important aspect biodiversity conservation.

Answer:
See below
Step-by-step explanation:
A fact that occurs naturally in the universe is a (scientific) law, for example, the law of gravity.
Depending on where Kevin lives, the scale probably measured the weight of his baggage in pounds or kilograms.
The symbol for pound is lb, and the symbol for kilogram is kg.
However, weight is a force, the attraction of the Earth's gravity for an object. Scientists measure force in units of newtons, symbol N.
Add 7 water atom to the right hand side to adjust the quantity of oxygen. Increase Cr(+3) by two to adjust the quantity of Cr. Duplicate Cl-by two to adjust the quantity of chlorine molecules.
Cr2O7[2-](aq) +2 Cl[-](aq) < - >2 Cr[3+] (aq) + Cl2(g)+7H2O
Presently adjust that charges.
you have - 4 charges on the left hand side, while +18 charges on the right hand side, there for include 14H+ the left hand side to adjust the charges
Cr2O7[2-](aq) +2 Cl[-](aq)+14H+ < - >2 Cr[3+] (aq) + Cl2(g)+7H2O
take note of that the oxidation number of hydrogen in water is +1
