PLease HELP How many molecules of CO2 are there in 55 grams of CO2?
Answer:
1.2mol
Explanation:
Determine the g/mol of CO2
O - 16g/mol (based on my data booklet)
C - 12.01g/mol (based on my data booklet)
Then add these values up for the g/mol of CO2
16+16+12.01= 44.01g/mol
Then write out the formula
mol = mass/molar mass
n= m/M
n = 55/44.01
n= 1.24971597
and depending on what significant digits you need (based on info, ill do it to 2 terms)
n = 1.2 mol
Molar mass is defined as the mass in grams of one mole of a substance. 1.2 molecules of CO2 are there in 55 grams of CO2.
What do you mean by molar mass ?The term molar mass is defined as the mass of a chemical compound divided by its amount-of-substance measured in moles. It is represented by the symbol "M". The units of molar mass are grams per mole, abbreviated as g/mol.
The weight of one mole of a sample is defined as its molar mass. To calculate a molecule's molecular mass, multiply the subscript by the atomic mass of each element in the molecule, then add the masses of all the elements in the molecule.
Molar mass of Oxygen - 16g/mol
Molar mass of Carbon - 12.01g/mol
Then add these values up for the g/mol of CO₂
Molar mass of CO₂ = 16+16+12.01
= 44.01g/mol
Then,
The number of mole = mass / molar mass
n = m / M
n = 55 / 44.01
n = 1.24971597
n = 1.2 mole
Thus, 1.2 molecules of CO2 are there in 55 grams of CO2.

Please help! Find the distance to each destination in AU. Use the correct conversion factor.
Explanation:
The question involves converting from one unit (Kilometres) to another unit (Astronomical unit)
The relationship between both units is given as;
1 Km = 6.68459e-9 Au
Kulper belt
6.5 billion km = 6.5e9 Km
1 Km = 6.68459e-9 Au
6.5e9 Km = x
Solving for x;
x = 43.45 Au
Alpha Centauri
44 trillion km = 4.4e13
1 Km = 6.68459e-9 Au
4.4e13 km = x
Solving for x;
x = 294121.83 Au

What will a balloon do to a cloth if its negatively charged
Answer:
This involves negatively charged particles (electrons) jumping to positively charged objects. When you rub the balloons against the fabric they become negatively charged. They take some of the electrons from the fabric and leave them positively charged.
Explanation:
Negative charges attract to positive charges. If a balloon is not rubbed with the wool cloth, it has an equal amount of negative to positive charges, so it will attract to a rubbed balloon. When both balloons are rubbed with the wool cloth, the both receive negative charges, so they will repel each other.

Which of these indicates that a liquid has transferred thermal energy to the air?
O The liquid increases in temperature, and its particles lose kinetic energy
O The liquid decreases in temperature, and its particles gain kinetic energy
O The liquid increases in temperature, and its particles gain kinetic energy.
O The liquid decreases in temperature, and its particles lose kinetic energy
No
Answer:
The liquid decreases in temperature and its particles lose kinetic energy.
Temperature is proportional to kinetic energy, so if temperature decreases, kinetic energy decreases. Energy has been removed from the liquid, because it is in the air
What is the % of each element in (NH4)2(SO4)?
Nitrogen=21.1999%
Hydrogen=6.1023%
Sulfur=24.2660%
The percent composition of nitrogen, hydrogen, sulfur , oxygen in ammonium sulfate is 21.18%, 6.05%,24.21%,48.43% respectively.
What is percent composition?The percent composition is defined as a convenient way to record concentration of solution.It is a expression which relates solute to solvent as,mass of solute/mass of solution ×100.It helps in elemental analysis of a given compound by giving proportions in which they are present.
Percent composition of N= 28/132.14×100=21.18%
Percent composition of H=8/132.14×100=6.05%
Percent composition of S=32/132.14×100=24.21%
Percent composition of O=64/132.14×100=48.43%.

1. If you have 5g of pennies how many dozen pennies do you have?
Answer:
15.69 dozen
Explanation:
Mass of penny = 5 g
Dozens of penny =..?
Next, we shall convert 5 g to gross. This can be obtained as follow:
3824 g = 1000 gross
Therefore,
5 g = 5 g × 1000 gross / 3824 g
5 g = 1.3075 gross
Thus, 5 g is equivalent to 1.3075 gross.
Finally, we convert 1.3075 gross to dozen. This can be obtained as follow:
1 gross = 12 dozen
Therefore,
1.3075 gross = 1.3075 gross × 12 dozen / 1 gross
1.3075 gross = 15.69 dozen
Thus, 5 g of penny is equivalent to 15.69 dozen

О O
It takes more energy to break the bonds of the reactants than is released when the
bonds in the products are formed
Answer: It takes more energy to break the bonds of the reactants than is released when the bonds in the products are formed
Explanation:
Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat. Thus it takes more energy to break the bonds of the reactants than is released when the bonds in the products are formed
Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat. Thus More energy is released when the bonds in the products are formed than is used to break the bonds in the reactants
