A rock is definitely more dense. If you were to put a cloud in water it would float/stay above it and a rock would sink to the bottom

What structural feature is different in isotopes of a particular element

8090 [49]

Answer:

atomic mass and number of neutrons

Explanation:

Isotopes are forms of same element having same number of protons.

As atomic number is same as number of protons, therefore, isotopes of an element have same atomic number also.

Isotopes differ from each other in having different number of neutrons.

Mass number is equal to no. of protons and no. of neutrons. As in isotopes no. of neutrons are different, therefore mass number will also be different.

Therefore, isotopes have different atomic mass and number of neutrons.

How many moles of PCl5 can be produced from 28.0 g of P4 (and excess Cl2 )? Express your answer to three significant figures and

umka2103 [35]

0.903 mol of PCl₅ can be produced from 28.0 g of P₄ (and excess Cl₂).

<h3>What is Stoichiometry ?</h3>

Stoichiometry helps us to use the balanced chemical equation to measure the quantitative relationship and it is to calculate the amount of product and reactants that are given in a reaction.

<h3 /><h3>What is Balanced Chemical Equation ?</h3>

The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.

Now write the balanced chemical equation

P₄ + 10 Cl₂ → 4PCl₅

1 mole of P₄ react with 10 mole of Cl₂ produces 4 moles of PCl₅.

According to Stoichiometry

$\frac{n_{P_4}}{1} = \frac{n_{PCl_5}}{4}$
