Can the same fertilizer be applied to all types of soil ? Explain

Arte-miy333 [17]

You cant use the same fertilizer for all soils bc differnt soils have different nutrients like lets say ur growing tomatoes with cabbage it wouldnt work bc they need different nutrients for them to grow. This is used with trees, veggies, plants and fruits. it is true somw can use the same fertilizer if they can be grown with it. if you give it the wrong nutrients it can die or not grow

Find the volume in milliliters of 2.00 mol of an ideal gas at 36°C and a pressure of 1120 torr.

hram777 [196]

Answer:

V = 34430 mL

Explanation:

Given data:

Volume in mL = ?

Number of moles of gas = 2.00 mol

Temperature = 36°C (36+273= 309K)

Pressure of gas = 1120 torr

Solution:

Formula:

PV = nRT

V = nRT/P

V = 2.00 mol ×62.4 torr • L/mol · K × 309K / 1120 torr

V = 38563.2 torr • L / 1120 torr

V = 34.43 L

L to mL

34.43 L ×1000 mL / 1 L

34430 mL

Rate law equation The rate of a chemical reaction depends on the concentrations of the reactants. For the general reaction betwe

jekas [21]

Answer: The reaction order with respect to A is 'm'

Explanation:

Order of the reaction is the sum of the concentration of terms on which the rate of the reaction actually depends. It is equal to the sum of the exponents of the molar concentration in the rate law expression.

Elementary reactions the reactions for which the order of the reaction is same as its molecularity and order with respect to each reactant is equal to its stoichiometric coefficient as represented in the balanced chemical equation.

The given chemical equation follows:

$aA+bB\rightleftharpoons cC+dD$

The rate of the above reaction is given to us as:

$Rate=k[A]^m[B]^n$

In the above rate law expression, the order with respect to the reactants is not equal to the stoichiometric coefficients. Thus, it is not an elementary reaction.

Order with respect to reactant A = m

Order with respect to reactant B = n

Hence, the reaction order with respect to A is 'm'
