Answers

Answer:

Final number of moles = 0.675 mol

Mass = 2.7 g

Explanation:

Given data:

Initial volume of gas = 2.00 L

Final volume of gas = 2.70 L

Initial number of moles = 0.500 mol

Final number of moles = ?

Solution:

Formula:

V₁/n₁ = V₂/n₂

V₁ = Initial volume

n₁ = Initial number of moles

V₂ = Final volume of gas

n₂ = Final number of moles

Now we will put the values in formula.

2.00 L /0.500 mol = 2.70 L / n₂

n₂ = 2.70 L× 0.500 mol /2.00 L

n₂ = 1.35 L.mol / 2.00 L

n₂ = 0.675 mol

Grams of helium added = ?

Solution:

Mass = number of moles × molar mass

Mass = 0.675 mol× 4 g/mol

Mass = 2.7 g

In a given chemical reaction, the energy of the products is less than the energy of the reactants. Which statement is true for this chemical reaction?

Answers

The answer is that, the reactants lose energy to the sorrounding during the reaction. This makes the products have less energy than the reactants that combined to produce them.

Answer:

The correct answer is B

How do crystal systems differ from eachother

Answers

The different crystal systems differ from each other in the angles between the axes and the lengths of the axes.

There are seven crystal systems:

Cubic: The cubic crystal system has three axes that are perpendicular to each other and of equal length.
Tetragonal: The tetragonal crystal system has three axes that are perpendicular to each other, but one axis is longer than the other two.
Orthorhombic: The orthorhombic crystal system has three axes that are perpendicular to each other, but none of the axes are of equal length.
Monoclinic: The monoclinic crystal system has three axes, two of which are perpendicular to each other and the third is at an angle to the other two.
Triclinic: The triclinic crystal system has three axes that are not perpendicular to each other.
Trigonal: The trigonal crystal system has three axes that are equal in length and intersect at 120-degree angles.
Hexagonal: The hexagonal crystal system has three axes that are equal in length and intersect at 120-degree angles, and a fourth axis that is perpendicular to the other three axes.

The cubic crystal system has the highest symmetry, while the triclinic crystal system has the lowest symmetry. The symmetry of a crystal system determines the properties of the crystal, such as its hardness, density, and electrical conductivity.

A crystal structure is composed of a unit cell, a set of atoms arranged in a particular way; which is periodically repeated in three dimensions on a lattice.
Crystal are classified according to the possible relations of the crystal axes.This classification is called as crystal system.

In a _______ mixture, the ingredients are distributed evenly throughout the mixture, while in a _______ mixture, the ingredients are unevenly distributed throughout.heterogeneous; homogeneous
heterozygous; homozygous
homozygous; heterozygous
homogeneous; heterogeneous

Answers

In a homogeneous mixture, the ingredients are distributed evenly throughout the mixture, while in a heterogeneous mixture, the ingredients are unevenly distributed.

The correct answer choice is the fourth one. You know this because you can eliminate the second and third choices since homozygous and heterozygous are terms more commonly used in genetics. And you can eliminate the first one because a homogenous mixture is more like a solution, where it is blended to where it looks like one substance. For example, pudding would be a homogenous mixture. So, homogeneous has to be in the first blank.

Answer:

homogeneous; heterogeneous

Explanation:

The way that a fluid flows depends on several factors. Briefly describe the factors – use as much scientific vocabulary that you can.

Answers

Answer:

Factors that influence flow :

Flow patterns in a fluid (gas or liquid) depend on three factors: the characteristics of the fluid, the speed of flow, and the shape of the solid surface. Three characteristics of the fluid are of special importance: viscosity, density, and compressibility. Viscosity is the amount of internal friction or resistance to flow. Water, for instance, is less viscous than honey, which explains why water flows more easily than does honey.

All gases are compressible, whereas liquids are practically incompressible; that is, they cannot be squeezed into smaller volumes. Flow patterns in compressible fluids are more complicated and difficult to study than those in incompressible ones. Fortunately for automobile designers, at speeds less than about 220 miles (350 kilometers) per hour, air can be treated as incompressible for all practical purposes. Also, for incompressible fluids, the effects of temperature changes can be neglected.
