hii thank you for helping me for that question please give me now this question define the air polution
Answer:
A mixture of solid particles and gases in the air.
Explanation:
Air pollution is a mixture of solid particles and gases in the air. car emissions, chemicals from factories, dust, pollen and mold spores may be suspended as particles. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it's also called smog.
Air pollution can be defined as the presence of toxic chemicals or compounds (including those of biological origin) in the air, at levels that pose a health risk. In an even broader sense, air pollution means the presence of chemicals or compounds in the air which are usually not present and which lower the quality of the air or cause detrimental changes to the quality of life (such as the damaging of the ozone layer or causing global warming).

aluminum has a density of 2.70 g/cm^3, a sample with a volume of 50 cm^3 will have how much mass?
Answer:
135 gExplanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question
density = 2.70 g/cm³
volume = 50 cm³
We have
mass = 2.70 × 50 = 135
We have the final answer as
135 gHope this helps you

what minimum frequency of light is required to ionize boron?
Answer:
frequency = 8.22 x 10¹⁴ s⁻¹
Explanation:
An electron's positional potential energy while in a given principle quantum energy level is given by Eₙ = - A/n² and A = constant = 2.18 x 10⁻¹⁸j. So to remove an electron from the valence level of Boron (₅B), energy need be added to promote the electron from n = 2 to n = ∞. That is, ΔE(ionization) = E(n=∞) - E(n=2) = (-A/(∞)²) - (-A/(2)²) = [2.18 x 10⁻¹⁸j/4] joules = 5.45 x 10⁻¹⁹ joules.
The frequency (f) of the wave ionization energy can then be determined from the expression ΔE(izn) = h·f; h = Planck's Constant = 6.63 x 10⁻³⁴j·s. That is:
ΔE(izn) = h·f => f = ΔE(izn)/h = 5.45 x 10⁻¹⁹ j/6.63 x 10⁻³⁴ j·s = 8.22 x 10¹⁴ s⁻¹

The correct name of the compound CuCl is copper I chloride.
An ionic compound is formed two atoms when one loose electrons and the other atoms gains those electrons. Ionic bonds are actually an ion pair, a pair of oppositely charged ions held together by electrostatic interaction. Transition metals are elements with incompletely filled d orbitals. Copper is a transition element.
The compound CuCl is named copper I chloride. We can see that the copper is in the +1 oxidation state in this compound hence the name.

An atom of radium (Ra) forms a monatomic ion.
Which ion does it most likely form?
a- Ra2-
b- Ra-
c- Ra2+
d- Ra+
Answer:
The atomic number of the element Radium (Ra) is 88. It is an alkaline earth metal. Electronic configuration of Radium (Ra) will be [Rn]7s^{2}[Rn]7s
2
It belongs to the group IIA of the periodic table. Alkaline earth metals that belong to the group IIA of the periodic table lose the valence electrons to form a +2 ion.
Therefore, Radium with an electronic configuration of [Rn]7s^{2}[Rn]7s
2
will lose the two 7s electrons to form the cation with +2 charge.

Based on electronegativity differences, which bond is a polar covalent bond?
Answer:
A bond in which the electronegativity difference between the atoms is between 0.4 and 1.7 is called a polar covalent bond.
A polar covalent bond is a covalent bond in which the atoms have an unequal attraction for electrons and so the sharing is unequal.
Regular table salt is sodium chloride, NaCl. It is a bonding of an Na+ ion and a Cl- ion. Which of these ions is bigger?
Answer:
in the periodic table we can see that the ions of Cl is greater than the ions in Na
Cl- ion is bigger than Na+ ion because of the presence of more number of electrons.
The atomic number of sodium+ ion is 10 means it has 10 number of electrons which can accommodate into 2 shells or orbits while on the hand, chlorine- ion has atomic number 18 means it has 18 number of electrons which can be accommodate into 3 shells or orbit.
So there is one shell more in chlorine ion as compared to sodium ion which make the size of chlorine ion large so we can conclude that chlorine ion is bigger than sodium ion.

Which statement correctly compares ice and liquid water?
A. Both liquid water and ice have definite shapes.
B. Particles of liquid water have more energy than particles of ice.
C. Liquid water has a lower temperature than ice.
D. Ice has a definite volume, but liquid water does not.
Answer:
B. Particles of liquid water have more energy than particles of ice.
Explanation:
We can work this out through eliminating the wrong statements.
A. Both liquid water and ice have definite shapes.
This is wrong because, as stated in the question, water is a liquid, and one of the properties of liquids is that they change shape to fit the shape of their container. If it changes shape, it does not have a "definite" shape.
B. Particles of liquid water have more energy than particles of ice.
This is correct, and here is why. There are 3 states of matter: solid, liquid and gas. As you apply heat energy to an object at each state, the particles receive more energy and can move around more (this is kinetic energy). In the case of liquid (water) and solid (ice), particles in solids do not have much energy and stay in rigid formations. They do vibrate slightly, but only on the spot (this is what gives solids "definite" shapes). On the other hand, particles in liquids have more energy than particles in solids, which means that they can move more (more kinetic ENERGY) and do not stay in formations (this is why they do not have "definite" shapes). Therefore, particles in liquids (water) have more energy than particles in solids (ice), and this statement is correct.
C. Liquid water has a lower temperature than ice.
This is wrong because liquids have more energy than solids. As explained earlier, the reason why particles in liquids have more energy is because more HEAT energy has been applied to them. In the same way, solids have less energy because less HEAT energy has been applied to them. Less heat means a lower temperature. (Also you can use common sense for this one, ice feels colder than liquid water, right?)
D. Ice has a definite volume, but liquid water does not.
This is wrong because of the law of conservation of mass. This law states that particles (or matter or volume) cannot be created or destroyed. When ice melts and becomes liquid water, it has not lost volume: the particles have just gained more energy. This question is most likely there to confuse you, because all substances have definite volumes.

If you weighed the atoms that appear on the reactant side of the equation, would they have the same mass as the atoms that appear on the product side?
Answer:
Yes,they will have the same mass.
Explanation:
According to law of conservation of mass:
'Mass can neither be destroyed nor be created during a chemical reaction'
In a balanced chemical reaction :
Total numbers of atoms on the reactants side are always equal to the total numbers of atoms on the product side.
Total mass of the atoms on the reactant side of the equation is always equal to the total mass of atoms on the product side.
For example:
Number of atoms on reactant side =
=(2)2 Hydrogen atoms + (1)2 Oxygen atoms = 6 atoms
Number of atoms on the product side =
=(2)((2 Hydrogen atoms) + (1 Oxygen atoms)) = 6 atoms
Mass of of reactants = (2)(number of hydrogen atoms)(mass of hydrogen atom) + (1)(number of oxygen atoms)(mass of oxygen atoms)
= (2)(2)(1u)+(1)(2)(16u) = 36u
Mass of products = 2((number of hydrogen atoms)(mass of hydrogen atom)+(number of oxygen atoms)(mass of oxygen atom))
= 2((2)(1u)+(1)(16u)) = 36u
Mass of of reactants = Mass of products = 36u

How do animals and plants rely on each other in the prairie? ITS TIMED
There are many decomposers in the prairie that can be used as food sources for first-order consumers.
There is more sunlight in the prairie for plants to grow, and therefore more food sources for animals.
Second-order consumers eat the grass as their food source.
The grass in the prairie provides oxygen, while animals give off carbon dioxide gas.
Answer:
I would assume its the last one "The grass in the prairie provides oxygen, while animals give off carbon dioxide gas."
