6. Write two major are or iron.
Explanation:
A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7.
A balloon occupies 175 cm at 25.0 C. What volume will it occupy at 42.5 °C?
175 cm³ instead of 175 cm.
Answer:
297.5 cm³
Explanation:
From the question;
Initial volume; V1 = 175 cm³
Initial temperature; T1 = 25°C
Final temperature; T2 = 42.5°C
From Charles law we can find the volume V2 from the equation;
V1/T1 = V2/T2
Making V2 the subject gives;
V2 = V1 × T2/T1
V2 = (175 × 42.5)/25
V2 = 297.5 cm³

Balance this equation. Pb(NO3)2(aq)+NaCl(aq) -> NaNO3(aq)+PbCl2(s)
Answer:
Pb(NO3)2(aq) + 2NaCl(aq) -> 2NaNO3(aq)+PbCl2(s)
Explanation:
Pb(NO3)2(aq)+NaCl(aq) -> NaNO3(aq)+PbCl2(s)
This is how it starts out.
Left:
2 NO3s1 Pb1 Na1 ClRight
1 Na1 NO31 Pb2 ClSo the place to start with this equation is to bring the Cls up to 2
Pb(NO3)2(aq)+2NaCl(aq) -> NaNO3(aq)+PbCl2(s)
But the Nas are now out of kilter.
Pb(NO3)2(aq)+ 2NaCl(aq) -> NaNO3(aq)+PbCl2(s)
Now the right has a problem. There's only 1 Na
Pb(NO3)2(aq) + 2 NaCl(aq) -> 2NaNO3(aq)+PbCl2(s)
Check it out. It looks like we are done.
What’s is CO written?
Answer:
CO is a chemical formula that contains one carbon atom (C) and one atom of oxygen (O). Altogether, CO translates to "carbon monoxide."
Explanation: Why monoxide and not dioxide? Well, the prefix mono means "one," and di means "two." Since there is only one oxygen atom (-oxide), then it must be monoxide! Voila!!
Identify 5 factors of weather
Answer:
"The five factors are: the latitude zone, the elevation of the land, topography (landforms), ocean currents and winds."
Explanation:
Answer:
The five factors that determine the weather of any land area are: the amount of solar energy received because of latitude; the area's elevation or proximity to mountains; nearness to large bodies of water and relative temperatures of land and water; the number of such storm systems as cyclones, hurricanes, and thunderstorms resulting from air-mass differences; and the distribution of air pressure over the land and nearest oceans, which produces varying wind and air mass patterns.

What is the definition for floating
Answer:
"1. buoyant or suspended in water or air.
2.not settled in a definite place; fluctuating or variable."
Explanation:
Hope this helps! :)
help !!! pretty please ❤️
Answer:
See below!
Explanation:
To find the symbol of the element, you have to use the periodic table.
The mass number is the number of protons and neutrons in the atom.
The atomic number is the number of protons in the atom.
You can find the number of protons from the periodic table.
You can find the neutrons by subtracting the mass number by the number of protons in the atom.
Unless you have an ion, you will have the same amount of electrons as you do protons.
To write in nuclear notation, you write the chemical symbol with the mass number and atomic number shown in the attachment. It is preferable to have the mass number and atomic number directly above each other.

Which of the following chemical formulas represents a molecule?
H2 CO2 SiO2 NH3
Answer:
H2
Explanation:
H (or hydrogen), being a halogen, as an atom, has 7 valence electrons. This means that it naturally bonds with another atom of the same isotope in order to reach the desired total of valence electrons: 8.
So... H+H = H2. EZ
Answer:
its all of them
Explanation:
i just did it lol but just incase, "Molecules are made of two or more atoms that are chemically bonded together. The atoms can be of the same element or of different elements. Therefore, H2, CO2, SiO2, and NH3 are all molecules."

1. You touch a shopping cart in the grocery store parking lot. What type of heat
transfer is happening between your hand and the handle?
Conduction
b. Convection
C. Radiation
d. Thermal Equilibrium
The transfer of energy between systems through work is the expansion of gas in a steam engine. By doing work or by transferring heat, energy can be transferred. Therefore, option A is correct option.
What is energy transfer?Energy transfer is a phenomenon in which energy transfer from one matter to another matter. Energy requirement is necessary to move any object so work has to be done by the gas to the piston.
Heat can be transferred by three ways radiation, convention or conduction. In conduction, direct contact of two body is necessary for transfer of molecules. When we touch a shopping cart in the grocery store parking lot, then conduction is the process by which heat is transferred between our hand and the handle.
Therefore, the option A is correct option that is conduction.

How many grams are in 8.50 e 23 formula units of NaCl?
a)82.5 g
b)8.25 g
c)85.0 g
d)91.5 g
Answer:
a)82.5 g
Explanation:
To solve this problem we will use Avogadro's number, which states the number of formula units per mole.
8.50x10²³formula units ÷ 6.023x10²³ formula units/mol = 1.41 molThen we convert 1.41 moles of NaCl to grams, using its molar mass:
1.41 mol NaCl * 58.44 g/mol = 82.4 gThe closest answer is option a).

When two objects of different temperatures are placed in contact with one another, eventually: (choose one option from below)
a) both their average kinetic energy and temperature will be the same
b) their average kinetic energy will be the same
c) neither their average kinetic energy and temperature will be the same
d) their temperature will be the same
Answer:
a) both their average kinetic energy and temperature will be the same
Explanation:
Temperature is the measure of the average kinetic energy of a system. As temperature increases, so will kinetic energy. As kinetic energy increases, speed increases. As one decreases, so does the other. When two objects are in contact with each other, their molecules will exchange energy and cause an eventual equilibrium of temperature and kinetic energy.
