Answer:

a) KOH

Explanation:

In the given balanced reaction

2K + 2H2O → 2KOH + H2

In the compound KOH,

The elements are K,O, and H and in the compound, there is one mole each of K , O ,and H.

So the element ratio here is 1 : 1 : 1.

<u>Answer:</u> The compound that has element ratio of 1 : 1 : 1 is KOH

<u>Explanation:</u>

Mole ratio is defined as the ratio of number of moles of the two elements combining to form a compound.

In a chemical compound, the subscripts represents the number of moles of elements in a compound.

For the given chemical reaction:

$2K+2H_2O\rightarrow 2KOH+H_2$

$H_2O$ has two elements, hydrogen and oxygen and is present in the ratio of 2 : 1

KOH has three elements, potassium, hydrogen and oxygen and is present in the ratio of 1 : 1 : 1

Hence, the compound that has element ratio of 1 : 1 : 1 is KOH

The total pressure of gases a, b, and c in a closed container is 4.1 atm. if the mixture is 36% a, 42% b, and 22% c by volume, w

Natali [406]

The partial pressure of gas C is 0.902 atm

calculation

partial pressure of gas c =[( percent by volume of gas C / total percent) x total pressure]

percent by volume of gas C= 22%

Total percent = 36% +42% + 22% = 100 %

Total pressure = 4.1 atm

partial pressure of gas C is therefore = 22/100 x 4.1 atm = 0.902 atm

Draw the structure of the neutral product formed in the reaction of dimethyl malonate and methyl vinyl ketone.

Dmitriy789 [7]

Answer:

Explanation:

The reaction between dimethyl malonate which is an active methylene group with an (∝, β-unsaturated carbonyl compound) i.e methyl vinyl ketone is known as a Micheal Addition reaction. The reaction mechanism starts with the base attack on the β-carbon to remove the acidic ∝-hydrogens and form a carbanion. The carbanion formed(enolate ion) attacks the methyl vinyl ketone(i.e. a nucleophilic attack at the β-carbon) to give a Micheal addition product, this is followed by the protonation to give the neutral product.

The concentration of species in 500 mL of a 2.104 M solution of sodium sulfate is ________ M sodium ion and ________ M sulfate i

omeli [17]

Answer:

The concentration of species in 500 mL of a 2.104 M solution of sodium sulfate is 4.208 M sodium ion and 2.104 M sulfate ion. (option E)

Explanation:

Step 1: Data given

Volume = 500 mL = 0.500 L

The concentration sodium sulfate = 2.104 M

Step 2: The equation

Na2SO4 → 2Na+ + SO4^2-

For 1 mol Na2SO4 we have 2 moles sodium ion (Na+) and 1 mol sulfate ion (SO4^2-)

Step 3: Calculate the concentration of the ions

[Na+] = 2*2.104 M = 4.208 M

[SO4^2-] = 1*2.104 M = 2.104 M

The concentration of species in 500 mL of a 2.104 M solution of sodium sulfate is 4.208 M sodium ion and 2.104 M sulfate ion. (option E)
