Answer:

The modern system of classification is a hierarchy with eight levels. These levels are domain, kingdom, phylum, class, order, family, genus, and species. There are three domains and six kingdoms in the modern system.

Answer:

its called TAXON0MY

Explanation:

they are classified in eight steps namely doma!n, k!ngdom, phylum, class, order, family, genus, and spec!es

but sometimes we do not include doma!n

if you want to name an organism you use both the genus group and the spec!es group

Example:

The scientific name for humans like us is h0m0 sap!ens

H0m0- This is our genus group

sap!ens- This is our spec!es group

sorry for using the exclamation mark it means i

Solution 1 consists of 80% benzene and 20% toluene. Solution 2 consists of 30% benzene and 70% toluene. a) How many mL of Soluti

Olenka [21]

Answer:

Answer a) is 2000 mL solution 1.

Answer b) is 40 mL solution 1 and 60 mL solution 2.

Answer c) isn't possible to produce a solution with 90% benzene and 10% toluene because is a percentage of benzene higher than the solution 1 and solution 2.

Explanation:

You can solve using an equation system base on the benzene percentage/ratio of each solution.

Answer a) X-> mL of solution 1

x*0.8+500*0.3=(500+ x)*0.7

x *0.8+500*0.3=500*0.7+ x*0.7

x*(0.8-0.7)=500*(0.7-0.3)

X*0.1=200

x=2000mL

Answer b) X-> mL of solution 1

x*0.8+(100-x)*0.3=(100)*0.5

x *0.8+100*0.3-x*0.3=50

x*(0.8-0.3)=50-30

x*(0.5)=20

x=40 mL

mL of solution 2=(100-x)=100-40=60 mL

Balance each reaction and write its reaction quotient, \text{Q}_c :(c) N₂O(g) + H₂(g) ⇄ NH₃(g) + H₂O(g)

Irina-Kira [14]

When we balance this equation

N₂O(g) + H₂(g) ⇄ NH₃(g) + H₂O(g)

We will get

N₂O(g) + 4H₂(g) ⇄ 2NH₃(g) + H₂O(g)

Solution:

Balancing this equation

N₂O(g) + H₂(g) ⇄ NH₃(g) + H₂O(g)

We have to balance the number of N

N₂O(g) + H₂(g) ⇄ 2NH₃(g) + H₂O(g)

We have to balance the number of H

N₂O(g) + 4H₂(g) ⇄ 2NH₃(g) + H₂O(g)

We get the balance equation

N₂O(g) + 4H₂(g) ⇄ 2NH₃(g) + H₂O(g)

The reaction quotient will be

Qc = [product] / [reactant]

Qc = [NH₃(g) + H₂O(g)] / [N₂O(g) + H₂(g) ]

Part A

sertanlavr [38]

Volume HNO₃ : 51.4 ml

Mass CO₂ : 0.17 g

<h3>Further explanation</h3>

Reaction

Na₂CO₃ + 2 HNO₃ ⇒ 2 NaNO₃ + CO₂ + H₂O

V Na₂CO₃ = 35.7 ml

M Na₂CO₃ = 0.108

mol Na₂CO₃ :

$\tt 35.7\times 0.108=3.8556~mlmol$

mol ratio Na₂CO₃ : HNO₃ = 1 : 2

mol HNO₃ :

$\tt \dfrac{2}{1}\times 3.8556=7.71~mlmol$

Volume HNO₃ :

$\tt mol=n=M\times V\\\\V=\dfrac{n}{M}=\dfrac{7.71}{0.15}=51.4~ml$

mol CO₂ = mol Na₂CO₃ = 3.8556 mlmol=0.00386 mol

mass CO₂(MW=44 g/mol) :

$\tt 0.00386\times 44=0.17~g$
