Air is trapped in a cylinder fitted with a piston that occupies 150.5 mL at 1.12 atm pressure. What is the new volume when the piston is depressed, increasing the pressure by 15%?

Answers

Answer 1

Answer:

New volume V2 = 120.4 ml

Explanation:

Given:

Pressure P1 = 1.12 atm

New pressure P2 = 1.12[1+0.25] = 1.4 atm

Old volume V1 = 150.5 ml

Find:

New volume V2

Computation:

P1V1 = P2V2

(1.12)(150.5) = (1.4)(V2)

V2 = 120.4 ml

New volume V2 = 120.4 ml

If the atomic number increases then the atomic radius should decrease right? So what’s wrong with my data

Answers

Answer:

Atomic radius increases by increasing the atomic number.

Explanation:

Atomic radius :

Atomic radius is the distance between nucleus of an atom to its outer most electronic shell.

Trend along group:

As we move down the group atomic radii increased with increase of atomic number. The addition of electron in next level cause the atomic radii to increased. The hold of nucleus on valance shell become weaker because of shielding of electrons thus size of atom increased.

As the size of atom increases the ionization energy from top to bottom also  decreases because it becomes easier to remove the electron because of less nuclear attraction and as more electrons are added the outer electrons becomes more shielded and away from nucleus.

The given data show that the atomic number in increased from 4 to 88 it means atomic radius also increased from 1.53Å to 2.83Å. It means the given data is the elements of periodic table present in group. It is the data of 2nd group of periodic table.

The force of attraction between one polar molecule and another polar molecule is​

Answers

Answer:

Dipole-dipole forces

Explanation:

A polar compound is that compound which contains atoms that have a difference in charges i.e electrostatic attraction occurs between its constituent atoms. Polar molecules are attracted to other polar molecules with opposite charges and her held together with the aid of certain forces

The attractive force between the negative part of a polar molecule (-) and the positive part of another polar molecule (+) is called DIPOLE-DIPOLE FORCES. This dipole-dipole force gets stronger with an increasing polarity of the molecules involved.

Which type of bond will chromium atoms likely to form with other chromium atoms
A:ionic
B:covalent
C:metallic

Answers

Answer: B

Explanation: Covalent bonds where electrons are not shared equally between two atoms are called polar covalent bond. As shown above, the electrons in a covalent bond between two different atoms (H and Cl in this case) are not equally shared by the atoms. This is due to the electronegativity difference between the two atoms.

There are two types of chemical compound one is covalent compound and other is ionic compound in chemistry. The covalent bond will be formed between two chromium atoms. the correct option is option B.

What is chemical Compound?

Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.

Covalent bond formed by sharing of electron and ionic bond formed by complete transfer of electron.

Element with same electronegativity difference combine together by covalent bond whereas ionic bond is formed by elements whose electronegativity difference is high.

As two chromium is combining that is two two element with same electronegativity is combining therefore, formation of covalent bond is the only possibility.

Therefore covalent bond will be formed between two chromium atoms. the correct option is option B.

Answers

Answer:

The invasive species would take over in the area and throw off the balance of the ecosystem.

Explanation:

Invasive species can harm both the natural resources in an ecosystem as well as threaten human use of these resources. An invasive species can be introduced to a new area via the ballast water of oceangoing ships, intentional and accidental releases of aquaculture species, aquarium specimens or bait, and other means.

Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats. This can result in huge economic impacts and fundamental disruptions of coastal and Great Lakes ecosystems.

A balloon filled with helium occupies 21.0ft³ at 55.0°F. Find the temperature of the helium if the volume of the balloon decreases to 11.0ft³. (Assume that the pressure is held constant.)​

Answers

Answer:

Assuming pressure is held constant,the question reduces to a ratio and proportion type of question where;

At constant pressure,

21.0ft³-55.0°F

11.0fy³=11.0ft³/21.0ft³×55°F

The temperature is 28.809°F≈29°F

29°F is the temperature of the helium if the volume of the balloon decreases to 11.0ft³.

What is temperature?

Temperature expresses hotness and coldness or a measure of the average kinetic energy of the atoms or molecules in the system.

Assuming pressure is held constant, the question reduces to a ratio and proportion type of question where;

At constant pressure,

21.0ft³- 55.0°F

11.0fy³ = 11.0ft³ ÷ 21.0ft³ × 55°F

The temperature is 28.809°F ≈ 29°F

Hence, 29°F is the temperature of the helium if the volume of the balloon decreases to 11.0ft³.
