what is the idea behid boyles law​

Answers

Answer 1

Answer:

Explanation:

For a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle's law is a gas law, stating that the pressure and volume of a gas have an inverse relationship. If volume increases, then pressure decreases and vice versa, when the temperature is held constant.

To solve this we must be knowing each and every concept related to planet. Therefore, the correct option is option C among all the given options.

What is planet?

A planet must accomplish three things: circle a star, be large sufficient to have sufficient gravity to compel a spherical form, and be large sufficient that its gravity swept away any similar-sized objects near its orbit.

Our solar system's planets did not arise out of nothing. The sun didn't either. They were all engulfed in a massive gas and dust cloud. Gravity gathered a lot of material inside the center to form the sun.

Astronomers send probes to other planets to take pictures of their surfaces. An astronomer thinks that briny water flows on Mars because he noticed certain features in one picture of Mars. Analyzing a natural experiment is a method to form this hypothesis.

Therefore, the correct option is option C.

what is the mass of 1.75 moles of HF?

Answers

Answer:

Mass = 35.02 g

Explanation:

Given data:

Number of moles = 1.75 mol

Mass of HF = ?

Solution:

Formula:

Mass = number of moles × molar mass

Molar mass of HF = 20.01 g/mol

by putting values,

Mass = 1.75 mol × 20.01 g/mol

Mass = 35.02 g

As the human population grows, the size of cities increases. As cities grow, more land must be cleared to make way for homes, businesses, and roads. Which two events would be likely effects of replacing a forested area with an urban area? A. More air pollution because there are fewer trees to take in carbon dioxide B. Less erosion of soil as plants covering the ground are added to gardens C. Fewer birds and other wildlife because they have fewer places to live D. More trees because of increased solar energy in the area​

Answers

Answer:1. Introduction

The main air pollutants are represented by gases forms, particles in suspension, different ionizing radiation and noise.

The gases forms are: oxidized and reduced forms of carbon (CO2, CO, CH4), of nitrogen (NO2, NO, N2O4, NH3, NH4+), SO2, O3, C6H6 vapours, Hg, volatile phenols, Cl2, etc.

The particulate forms are: PM10 and PM2.5 particulate matter, heavy metals with toxic effect (Pb, Ni, Cd, As), polycyclic aromatic hydrocarbons PAHs, etc.

Atmospheric pollutants have a negative effect on the plants; they can have direct toxic effects, or indirectly by changing soil pH followed by solubilization of toxic salts of metals like aluminum. The particulate matters have a negative mechanical effect. They cover the leaf blade reducing light penetration and blocking the opening of stomata. These impediments influence strongly the process of photosynthesis which rate declines sharply.

A More air pollution because there are fewer trees to take in carbon dioxide

Answers

The empirical formula is the same as the molecular formula : C₁₀H₅O₂

Further explanation

Given

Molecular formula : C₁₀H₅O₂

Required

The empirical formula

Solution

The empirical formula (EF) is the smallest comparison of atoms of compound forming elements.  

The molecular formula (MF) is a formula that shows the number of atomic elements that make up a compound.  

(empirical formula) n = molecular formula  

(EF)n=MF

(EF)n = C₁₀H₅O₂

If we divide by the number of moles of Oxygen (the smallest) which is 2 then the moles of Hydrogen will be a decimal number (not whole), which is 2.5, then the empirical formula is the same as the molecular formula

From my side the correct option is "A"

Explanation:    Reasons for its correction are ,

1)  Highly reactive: Nanoparticles are therefore extremely unstable and easily change themselves or react with active substances to reach a relatively stable state in some cases. This causes desired changes or undesired changes to nanoparticles and thus makes them exhibit a high reactivity and a poor stability.

2)Small size:  Nanotechnology can provide rapid and sensitive detection of cancer-related molecules, enabling scientists to detect molecular changes even when they occur only in a small percentage of cells. Nanotechnology also has the potential to generate entirely novel and highly effective therapeutic agents.

When a fluorine atom becomes an ion, it will
A) gain an electron and increase in size
B) lose an electron and increase in size
C) gain an electron and decrease in size
D) lose an electron and decrease in size

Answers

Answer:

A) gain an electron and increase in size

Explanation:

Fluorine is a Group 17 element, making it a halogen. This means that it has 7 valence electrons in its outer shell. It only needs one more electron to fill its outer shell and gain stability. When fluorine becomes an ion, it gains an electron and becomes F⁻. Adding electrons creates a larger ion because the electrons occupy a larger volume due to mutual repulsions pushing them apart.

Hope that helps.

When a fluorine atom becomes an anion, it will gain an electron and increase in size. Therefore, option (A) is correct.

What is an ion?

An ion is a chemical specie that holds a positive or negative charge. The term ‘ion’ refers to atoms or molecules with non-zero net charges associated with them. Therefore, all ions have either a greater number of electrons than protons in their atomic structures or a greater number of protons than electrons.

If the number of protons is greater than electrons are termed to hold a net positive charge and are commonly referred to as cations. The ions that contain a greater number of electrons than protons hold a net negative charge and are known as anions.

The electronic configuration of the fluorine is 1s²2s²2p⁵. As the fluorine atom accepts one electron in its valence shell it becomes anion F⁻. The number of protons is less than electrons therefore effective nuclear charge decreases and the size of the ion increases.

What is  an atom?

An atom is defined as the smallest unit of matter which forms an element. Every form of matter whether solid,liquid , gas consists of atoms . Each atom has a nucleus which is composed of protons and neutrons and shells in which the electrons revolve.

The protons are positively charged and neutrons are neutral and hence the nucleus is positively charged. The electrons which revolve around the nucleus are negatively charged and hence the atom as a whole is neutral and stable due to presence of oppositely charged particles.

Atoms of the same element are similar as they have number of sub- atomic particles which on combination do not alter the chemical properties of the substances.

The basic principle of the number of elements in reactants and products is the same used in balancing chemical equations

Further explanation

Given

The chemical equation

Required

The balanced equation

Solution

Equalization of chemical reactions can be done using variables. Steps in equalizing the reaction equation:  

• 1. gives a coefficient on substances involved in the equation of reaction such as a, b, or c, etc.  

• 2. make an equation based on the similarity of the number of atoms where the number of atoms = coefficient × index (subscript) between reactant and product  

• 3. Select the coefficient of the substance with the most complex chemical formula equal to 1

We give an example for reaction number 1:

aAl + bHCl → AlCl₃ + cH₂

Al, left = a, right = 1⇒a=1

Cl, left = b, right = 3⇒b=3

H, left = b, right = 2c⇒b=2c⇒3=2c⇒c=3/2

The equation becomes :

Al + 3HCl → AlCl₃ + 3/2H₂ x2

2Al + 6HCl → 2AlCl₃ + 3H₂

The steps are the same for the other reactions

2. 2Al + 3S → Al₂S₃

3. 4NO₂ + O₂ → 2N₂O₅

4. 4Al + 3O₂ → 2Al₂O₃

5. Ba(ClO₃)₂ → BaCl₂ + 3O₂

For species that reproduce asexually, all their offspring are
A. genetically identical
B. genetically different
C. almost identical
D. slightly different​

Answers

Answer:

A. genetically identical

Explanation:

Asexual reproduction produces offspring that are genetically identical to the parent because the offspring are all clones of the original parent. A single individual can produce offspring asexually and large numbers of offspring can be produced quickly

All the offspring that are produced in the process are genetically identical.

When we talk about this mode of reproduction, we talk about a mode of reproduction in which an organism reproduces without the fusion of gametes. This occurs essentially by cell division.

When this occur, there is no crossing of genetic material as such, all the offspring that are produced in the process are genetically identical.
