Answer : The correct option is, (A) There is more than one reactant.

Explanation :

Synthesis reaction : Synthesis reaction are those reactions in which more than one reactants react to form a single product or a compound.

The general representation of the synthesis reaction is,

$A+B\rightarrow AB$

In this, A and B are the reactants and AB is the product.

For example : formation of calcium hydroxide from calcium oxide and water.

$CaO(s)+H_2O(l)\rightarrow Ca(OH)_2(s)$

Hence, the correct answer is, (A)

If 3.89 × 1024 atoms of a noble gas is collected and it has a mass of of 848 grams, this element is most likely a. He b. Ne c. A

bearhunter [10]

Answer:

Xenon

Explanation:

Avogadro’s number represent the number of the constituent particles which are present in one mole of the substance. It is named after scientist Amedeo Avogadro and is denoted by $N_0$ .

Avogadro constant:-

$N_a=6.023\times 10^{23}$

Let the molar mass of the element is x g/mol

So,

$6.023\times 10^{23}$ atoms have a mass of x g

Also,

$3.89\times 10^{24}$ atoms have a mass of $\frac{x}{6.023\times 10^{23}}\times 3.89\times 10^{24}$ g

This mass is equal to 848 g

So,

$\frac{x}{6.023\times 10^{23}}\times 3.89\times 10^{24}=848$

x= 131.3 g/mol

This mass correspond to xenon.
