Answer:

3.0 moles of water

Explanation:

Having the balanced equation of water production

2H2 (g) + O2 (g) -----> 2H2O (g)

Given that 3.0 moles of hydrogen gas reacts with 1.8 moles of oxygen gas

from the 2 moles of hydrogen are required to react with 1 mole of oxygen

1.8 moles of oxygen,requires 1.8 mol O2 x 2 mol H2/ 1 mol O2 = 3.6 mol H2

this means that H2 is the limiting reagent while oxygen is in excess,thus we use the moles of H2 to find the ,moles of water produced.

from the equation, 2 moles of H2 produces 2 moles of H2O

moles of H2O = 3.0 mol H2 x 2 mol H2O/ 2mol H2 = 3.0 molH2O

Therefore 3.0 moles of water are produced.

Why is the potassium atom larger than the kypton atom

gogolik [260]

This is because of the increasing number of protons in the nucleus, resulting in a stronger attraction of the electrons with the nucleus.

What is the symbol (including the atomic number, mass number, and element symbol) for the nitrogen isotope with 8 neutrons? Expr

Doss [256]

Answer: The isotope is represented as $_7^{15}\textrm{N}$

Explanation:

General representation of an element is given as: $_Z^A\textrm{X}$

where,

Z represents Atomic number

A represents Mass number

X represents the symbol of an element

Atomic number is defined as the number of protons or number of electrons that are present in an atom.

Atomic number = Number of electrons = Number of protons = 7 (for nitrogen)

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons = 7+8 = 15

Thus the isotope is represented as $_7^{15}\textrm{N}$

Some students were building models of solids, liquids, and gases by gluing plastic balls to a sheet of cardboard. which of their

JulsSmile [24]

Below picture contains the given models.

Answer:
Option-B is the correct model.

Explanation:
Solid is a state of matter in which the particles are closely packed, has definite volume and shape. Like liquids they don't flow, either they occupy the volume of container as that occupied by both gases and liquids. The inter-molecular forces between solid particles are very strong as compared to liquids ans gases. So, the model B has a particles very closely packed to each other.

Draw the structure of (z)-3-bromo-6-methyl-2-heptene. be sure the stereochemistry is drawn clearly.

Anna007 [38]

Explanation: In IUPAC, E-Z convention is given for describing the cis - trans notation to the isomers. According to CIP rule, the groups on the doubly bonded carbon atoms are given priorities based on the the atomic masses of first connected atom.

If the highest priority groups are on the same side, it is known as Z-form and if the highest priority groups are on opposite side, it is known as E-form.

We are given (Z)-3-bromo-6-methyl-2-heptene, in this the highest priority groups are bromine on one side and methyl- group on another side.

The structure is provided in the image below.
