How many moles of silver would precipitate out when 3.6 x 10^23 atoms of zinc are combined in silver nitrate according to the following unbalanced equation? (Balance equation first!)

Zn + AgNO3 → Zn(NO3)2 +Ag

A: 1.67 moles
B: 1.2 moles
C: 3.34 moles
D: 0.6 moles

Can someone please help me with this I don’t get it at all.

Answer:

Fe2O3

Explanation:

Answer:

Concentration gradient, size of the particles that are diffusing, and temperature of the system affect the rate of diffusion. Some materials diffuse readily through the membrane, but others require specialized proteins, such as channels and transporters, to carry them into or out of the cell.

Answer: 322.56 Kelvin

Explanation:

Use the Ideal Gas Law

[tex]PV=nRT[/tex]

R is the gas constant

T is the temperature in Kelvins

P is the pressure in atmospheres

V is the volume in liters

n is the number of moles of gas

First, the mm of mercury need to be converted to atmospheres using the conversion factor 1atm = 760 torr.

[tex]751.2mmHg (torr) =0.988atm[/tex]

Now plug everything in

[tex](0.988)(26)=(0.97)(0.0821)T\\T=322.56K[/tex]

Answer: Fossil fuels may be used in the production of biofuels.

Explanation: Defeats the purpose of using biofuels over fossil fuels if one contains the other.

Answer:

D

Biofuel Disadvantages:

Labor costs are high, and storage space is limited. Excessive water use, particularly in dry areas. Increasing biomass for biofuel production raises agricultural land requirements.

Specific examples of electrical energy include:

Alternating current (AC)

Direct current (DC)

Lightning

Batteries

Capacitors

Energy generated by electric eels

Explanation:

Electrical energy used for electric power, such as wall current used to power a light bulb or computer, is energy that is converted from electric potential energy. This potential energy is converted into another type of energy (heat, light, mechanical energy, etc). For a power utility, the motion of electrons in a wire produces the current and electric potential.

A battery is another source of electrical energy, except the electrical charges may be ions in a solution rather than electrons in a metal.

Biological systems also use electrical energy. For example, hydrogen ions, electrons, or metal ions may be more concentrated on one side of a membrane than the other, setting up an electrical potential that can be used to transmit nerve impulses, move muscles, and transport materials.

Explanation:

energy= mass × specific heat capacity of water × change in temperature

=32.7×4.184×(77-12)

Answer:

New volume v2 = 300.8 ml

Explanation:

Given:

Old volume v1 = 752 ml

Old temperature T1 = 25°C

New temperature T2 = -10°C

Find:

New volume v2

Computation:

Using Ideal gas law formula

V1T2 = V2T1

(752)(-10) = (V2)(25)

New volume v2 = 300.8 ml

Group 0 is the noble gas elements in periodic table. They are all unreactive because, they have completely filled electronic configuration and thus they are stable. This stability to be a single element make them so.

Noble gases are helium, neon, argon, krypton and xenon. They are 18th group elements in periodic table. Also called zero group elements. The general electronic configuration of these elements is ns² np⁶.

Noble gases contains eight electrons in their valence shell and thus completed octet. Atoms with less number of electrons in valence shell tends to attain octet by losing or gaining electrons to their valence shell.

Every elements except noble gases are electron deficient or electron rich. The electron rich elements will lose their electron to attain stability and the elements with less electrons gain them through bonding. That's why they are existing as molecules.

Therefore, the elements of zero group are highly stable and they do not lose or gain electrons to form molecules.

Answer:Temperature affects storage time and food deteriorates faster at higher temperatures. Microorganisms grow rapidly at room temperature . Thus to slow microbial growth, enzymatic and oxidative processes, food must be stored at room temperature.

Due to decomposition reactions with oxygen or carbon dioxide in the air, meat begins to feel slimy and smell spoiled. ... Because of its smaller surface area, the unsliced meat would have less collisions and therefore, a slower reaction rate.

Answer:

Energy can change form, so False

Answer: False

Explanation:Energy readily changes from one form to another. The law of Conservation of Energy states that "Energy cannot be created or destroyed.". In other words, the total amount of energy in the universe never changes, although it may change from one form to another. Energy never disappears, but it does change form.

Answer:

[tex]a=123.04\ m/s^2[/tex]

Explanation:

Given that,

Force applied to a soccer player, F = 56.6 N

The mass of the ball, m = 0.46 kg

We need to find the acceleration of the soccer ball. The force acting on the ball is given by :

F = ma

Where

a is the acceleration

[tex]a=\dfrac{F}{m}\\\\a=\dfrac{56.6 }{0.46 }\\\\a=123.04\ m/s^2[/tex]

So, the required solution is [tex]123.04\ m/s^2[/tex].
