Answer: 2.85 moles of flourine
Explanation:
find the atomic/molar mass of flourine on your periodic table.
multiply the given mass (54.1g) by (1 mole of flourine/atomic mass of flourine)
54.1g flourine * 1mole of flourine/18.998g flourine
(g flourine) in the above equation cancel each other.
54.1/18.998 = 2.85 mole of flourine

An unknown material has a mass of 4.5 g and a volume of
6.75 cm3. What is the density
Answer:
0.67 cm³Explanation:
The density of a substance can be found by using the formula
[tex]density = \frac{mass}{volume} \\[/tex]
From the question
mass = 4.5 g
volume = 6.75 cm³
We have
[tex]density = \frac{4.5}{6.75} \\ = 0.6666666...[/tex]

How does the use of synthetic products impact the natural resource from which they are derived?
Answer:
The series of chemical reactions that are used to change natural resources into synthetic products is called chemical synthesis. To make a "natural" product, the natural resource is not chemically changed as much. ... For example, the synthetic material plastic is made from petroleum, which is pumped out of the earth.
Explanation:
give brainliest!!!!
The use of synthetic products impact the natural resources from which they are derived by depleting the natural resource and causing harm to it.
What are natural resources?Resources which are obtained from nature by a few modifications in them are called natural resources.These are resources which are available in nature . Every synthetic product is composed of natural resources.
It may exist in a form of separate entity or in form of living-beings or the can even be transformed into products which are of economic importance.Because of the transformation of natural resources into products of economic importance they are getting depleted at a rate which much times greater than the rate it was getting depleted several years ago.
As the products available today comprise of synthetic products natural resources are getting depleted which is becoming a global concern.

Que instrumentos de laboratorio usaron luis y Juan?
Luis y Juan querían hacer una investigación sobre la rapidez de disolución de una pastilla efervescente en el ácido acético a temperatura caliente. Para esto, tenían que triturar la pastilla y luego utilizar solamente 15 gramos de la sustancia. Tenían que medir 50 ml de ácido acético y colocar el mismo en un recipiente donde se pueda calentar sustancias, pero que el vapor generado se libere rápido. Al agregar ambas sustancias al recipiente de vidrio, lo comenzaron a calentar. Una vez se iba calentando, agitaron las sustancias poco a poco y con mucho cuidado, tomaron los cambios en temperatura de cada 2 minutos. Al finalizar el experimento, ellos compartieron sus resultados con sus compañeros de clase.

The molar mass of sulfur S is 32.06 g/mol
Calculate the mass in grams of a sample of S containing 2.01x10^24 atoms
Help Please<3
Since we are starting from the number of atoms of Sulfur, we need to know two sets of formulas:
mass = moles × molar mass moles = atoms ÷ Avogadro's Number
⇒ mass = (atoms ÷ Avogadro's Number) × molar mass
mass = [(2.01 × 10²⁴ atoms) ÷ (6.022 × 10²³ atoms/mole)] × (32.06 g/mol)
= 107.01 g
the mass of a sample of S containing 2.01×10²⁴ atoms is 107.01 g.The molar mass of sulfur S is 32.06 g/mol, then the mass in grams of a sample of S containing 2.01x10^24 atoms is 107.01 g
what is molar mass ?The molar mass can be defined as the weight of one sample mole, by Multiplying the subscript means the number of atoms times that element’s atomic mass and add the masses of all the elements in the molecule to obtain the molecular mass.
Molar mass is expressed in either gram ( g) or kilograms (kg).
Mass = moles × molar mass
moles = atoms ÷ Avogadro's Number
⇒ mass = (atoms ÷ Avogadro's Number) × molar mass
mass = [(2.01 × 10²⁴ atoms) ÷ (6.022 × 10²³ atoms/mole)] × (32.06 g/mol)
= 107.01 g

which factor increases as the efficiency of a machine increases
Answer:
Because all machines lose input work to friction, one way to improve the efficiency of a machine is by reducing friction. Oil is used to reduce friction between the moving parts of car engines. The use of oil makes engines more efficient. Another machine that loses input work is a bicycle.
Explanation:
Hope this helps.
The factor which increases as the efficiency of a machine increases is: work output.
Efficiency can be defined as a ratio of work (energy) output to work (energy) input.
Mathematically, the efficiency of a machine is given by the formula:
[tex]Efficiency = \frac{W_O}{W_I} \times 100[/tex]
Where:
Wo is the work output.Wi is the work input.Work can be defined as the amount of energy required to move an object from one point to another.
Hence, the work done by a machine is the product of the perpendicular force acting on the machine and the distance it covers or travels.
Ideally, the work output of a machine is highly dependent on its efficiency and as such, it is a factor which increases as the efficiency of a machine increases

Answer:
In fact, the moon is one of the least reflective objects in the solar system. The DSCOVER spacecraft captured this single photograph of the moon and the earth. Both the earth and the moon are illuminated by the same amount of sunlight coming from the same angle in this photo.
The moon shines because its surface reflects light from the sun. And despite the fact that it sometimes seems to shine very brightly, the moon reflects only between 3 and 12 percent of the sunlight that hits it. The perceived brightness of the moon from Earth depends on where the moon is in its orbit around the planet.
