How many molecules are in 5.5 moles of CUNO3?
Setler [38]

Answer:

1.48381734165x 10²⁵ molecules

Explanation:

1 grams CuNo3 is equal to 0.0011897028836018 mole.

x = 5.5 moles

x = 5.5 x 1/0.0011897028836018 = 5.5/0.0011897028836018

4623.003grams

the molar mass of cuno3 =187.56 = 6.02 x10²³

4623.003g = x

187.56x = 4623.003 x 6.02 x10²³  = 27830.47806 x10²³ =  1.48381734165x 10²⁵

List the number of each type of atom on the left side of the equation 2C6H14(l)+19O2(g)→12CO2(g)+14H2O(g) Enter your answers sep
murzikaleks [220]

<u>Answer:</u> The number of carbon, hydrogen and oxygen atoms on the left side of the reaction are 12, 28 and 38 respectively

<u>Explanation:</u>

In a chemical equation, the chemical species are termed as reactants or products.

Reactants are defined as the species which react in the reaction and are written on the left side of the reaction arrow.

Products are defined as the species which are produced in the reaction and are written on the right side of the reaction arrow.

For the given chemical equation:

2C_6H_{14}(l)+19O_2(g)\rightarrow 12CO_2(g)+14H_2O(g)

On the reactant side:

Number of carbon atoms = (6 × 2) = 12

Number of hydrogen atoms = (14 × 2) = 28

Number of oxygen atoms = (2 × 19) = 38

Hence, the number of carbon, hydrogen and oxygen atoms on the left side of the reaction are 12, 28 and 38 respectively

The answer is:

carboxylate

and protonated amines

The explanation:

when

The Carboxylic acids are polar . and the functional group carboxyl is formed from the hydroxyl and carbonyl group.

and about protonated amines:

-alkyl groups improve the basicity, aryl groups diminish it.

-Primary amides have an aromatic group or alkyl attached to an amino-carbonyl function.

- Primary amines are basic functions which could be protonated to the  ammonium ion
