2. How many moles are in 8.30 x 1023 molecules of H2O?
daser333 [38]

Answer:

<h2>1.38 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{8.30 \times  {10}^{23} }{6.02 \times  {10}^{23} }  =  \frac{8.30}{6.02}  \\  = 1.3787 37...

We have the final answer as

<h3>1.38 moles</h3>

Hope this helps you

Identify the type of reaction described in the sentence below. then, write a chemical equation. be sure to specify the states of
natulia [17]

Answer : The type of reaction described in the sentence is Synthesis or Combination

Explanation :

The balanced equation for the reaction between Phosphorous and Oxygen gas can be written as

4P (s) + 5O_{2} (g) ------>  P_{4} O_{10}  (s)

From the above equation we can see that there are two different reactants ( P and O₂ ) which are combining with each other to give a single product.

This type of reaction is known as Combination or Synthesis.

A general form of Synthesis reaction is given below.

A + B ---->  AB

Here we can conclude that a synthesis / combination reaction is the one where 2 or more reactants combine together to give only one product .
