Answer:  Thus mass of products is 177.2 g

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

The balanced chemical reaction is:

[tex]AgNO_3+NaCl\rightarrow NaNO_3+AgCl[/tex]

mass of silver nitrate [tex](AgNO_3)[/tex] = 124.31 g

mass of sodium chloride [tex](NaCl)[/tex] = 52.89 g

mass of reactants = mass of silver nitrate [tex](AgNO_3)[/tex] +

mass of sodium chloride  [tex](NaCl)[/tex] = 124.31 g + 52.89 g = 177.2 g

Thus mass of products = mass of reactants = 177.2 g

I think the answer would be option d.

Answer:

In anaerobic respiration, glucose breaks down without oxygen. The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water. Unfortunately this can lead to painful muscle cramps.

Answer:

In anaerobic respiration, glucose breaks down without oxygen. The chemical reaction transfers energy from glucose to the cell. Anaerobic respiration produces lactic acid, rather than carbon dioxide and water. Unfortunately this can lead to painful muscle cramps.

Explanation: Living things need energy for everything they do, including growing and reproducing. This energy comes from glucose. All animals and humans get glucose through eating it, but plants need to make their own glucose during photosynthesis.

Plants and animals transport glucose and oxygen to tiny structures in their cells, called mitochondria. Here, the glucose and oxygen take part in a chemical reaction. The reaction is called aerobic respiration, and it produces energy which transfers to the cells.

Aerobic respiration makes two waste products:carbon dioxide and water. Animals remove carbon dioxide from their bodies when they breathe out. In daytime, plants use some of this carbon dioxide for photosynthesis. At night, they release the carbon dioxide to their surroundings.

Answer:

81 x as bright

Explanation:

The intensity of light is dependent on distance according to this simple equation:

(90/10)^2 = 9^2

                = 81

This was derived from the inverse-square law. Respectively a light that is 10 m away from you is 81 x as bright.

Answer: V has the units of liters, and T has the units of kelvin.

Ideal gas law: p·V = n·R·T.  

atm · L = mol · L·atm/mol·K · K; both side of equatation have same values.

R = 0,08206 L·atm/mol·K; universal gas constant.  

p is pressure of the gas, unit is standard atmosphere (atm).

V is volume of the gas, unit is liters (L).

n is amount of substance of the gas; unit is mole (mol).

T is temperature of the gas, unit is Kelvin (K

Hope this helps!!

Answer: V has the units of liters, and T has the units of kelvin.

A Family Portrait

That element is NOT in the family. When we told you about families, we said that they were groups of elements that react in similar ways. Hydrogen is a very special element of the periodic table and doesn't belong to any family. While hydrogen sits in Group I, it is NOT an alkali metal.

Answer:

Explanation:

The chemical properties are so different and cannot be group into a family Hydrogen is the simplest, smallest and lightest of the elements. Unlike the other elements of the periodic table, the combination of properties it exhibits doesn't match any one single grouping or family.

An atom is a kind of stuff that cannot be further decomposed chemically. Therefore, the charge on a single proton is +1.

The building block of an element is an atom. An atom is a kind of stuff that cannot be further decomposed chemically. The three main components of an atom are protons, neutrons, plus electrons.

Some substances are either bigger or smaller than atoms. Instances of chemical species that aren't commonly regarded as atoms include protons, neutrons, and electrons, which are atom-related particles. Atoms make up molecules and compounds, however they are not actual atoms. Salt is an example of a molecule and a compound (NaCl). The charge on a single proton is +1.

Therefore, the charge on a single proton is +1.

170.034 L is the volume of a container containing 7.59 moles of krypton gas at STP.

The ideal gas equation, pV = nRT, is an equation used to calculate either the pressure, volume, temperature or number of moles of a gas.

Using the ideal gas equation

PV =nRT

Where P is the pressure

V is the volume

n is the number of moles

R is the ideal gas constant (R = 0.08206 L atm mol⁻¹ K⁻¹)

T is the temperature.

From the given information

V =?

n = 7.59

and at STP

P = 1 atm

T = 273 K

Putting the parameters into the formula, we get

PV =nRT

1 atm x V = 7.59 mol x 0.08206 L atm mol⁻¹ K⁻¹ x 273 K

V = 170.034 L

Hence, 170.034 L is the volume of a container containing 7.59 moles of krypton gas at STP.

Answer:

1) The light microscope. The common light microscope used in the laboratory is called a compound microscope because it contains two types of lenses that function to magnify an object. The lens closest to the eye is called the ocular, while the lens closest to the object is called the objective. Most microscopes have on their base an apparatus called a condenser, which condenses light rays to a strong beam.

2) Other light microscopes. In addition to the familiar compound microscope, microbiologists use other types of microscopes for specific purposes. These microscopes permit viewing of objects not otherwise seen with the light microscope.

3) The fluorescent microscope uses ultraviolet light as its light source. When ultraviolet light hits an object, it excites the electrons of the object, and they give off light in various shades of color. Since ultraviolet light is used, the resolution of the object increases. A laboratory technique called the fluorescent‐antibody technique employs fluorescent dyes and antibodies to help identify unknown bacteria.
