Answer:
When the energy is passed on from one trophic level to another, only 10 percent of the energy is passed on to the next trophic level.
Explanation:
Answer:
Turnover number = 113182s⁻¹
Explanation:
Turnover number is a concept used to know the activity of an enzyme. The higher turnover number, the higher activity of the enzime.
Turnover number is defined as:
Turnover number = Rmax / [E]t
As Rmax is 249 μmol⋅L⁻¹⋅s⁻¹ and [E]t is 2.20 nmol⋅L⁻¹
As 1μmol = 1000nmol, Rmax = 249000 nmol⋅L⁻¹⋅s⁻¹. Replacing:
Turnover number = 249000 nmol⋅L⁻¹⋅s⁻¹ / 2.20 nmol⋅L⁻¹
<h3>Turnover number = 113182s⁻¹</h3>
Answer:
The terms used to describe the given process in <em><u>Chemical weathering.</u></em>
Explanation:
Weathering of rock is defined as breaking down of the rock into small pieces.
There are two types pf weathering :
Mechanical weathering : This weathering is due to change in physical parameters : temperature change, pressure change etc.
For example : When water soaked up in cracks or crevices of rocks freezes it expands and physically breaks the rock.
Chemical weathering : This weathering is decomposition of rocks due to action of chemicals.This type of weathering also changes chemical composition of rocks.
For example : when gases like carbon dioxide, sulfur oxide get dissolves in water present in rock to form weak acid which ease up the dissolving of rock in that weak acid.
The correct formula : BeSO₄
<h3>Further explanation</h3>
Chemical formula shows the composition number of the constituent atoms
Polyatomic ion consists of 2 or more ions
The equal charge of the two ions will cancel each other out, while the different charges of the two ions will be crossed each other
Be²⁺ (monatomic ion) has a positive charge of +2, while SO₄²⁻ (polyatomic ion) has a negative -2 charge, so that the two charges with the same magnitude but with different charges cancel each other out so that the compound form is BeSO4
This is a Charles' Law problem: V1/T1 = V2/T2. As the temperature of a fixed mass of gas decreases at a constant pressure, the volume of the gas should also decrease proportionally.
To use Charles' Law, the temperature must be in Kelvin (x °C = x + 273.15 K). We want to solve Charles' Law for V2, which we can obtain by rearranging the equation into V2 = V1T2/T1. Given V1 = 25 L, T1 = 1200 °C (1473.15 K), and T2 = 25 °C (298.15 K):
V2 = (25 L)(298.15 K)/(1473.15 K) = 5.1 L.
