In an experiment, 2.54 grams of copper completely reacts with sulfur, producing 3.18 grams of copper(I). Determine the total mas

s of sulfur consumed. And write the chemical formula of the compound produced.
Please help me!!!

3.18 grams of product (Cu I) - 2.54 grams of Cu (reactant) = .64 grams of Sulfur, by law of conservation of mass.

how will knowing the density of a substance help you determine whether an object made from that material will float in water

trapecia [35]

The density of water is about 1kg/m³, therefore is the substance has a density of less than 1kg/m³ then it will most likely float however if it is more than 1kg/m³ then it will most likely sink.

The atomic number of argon is 18. will argon tend to form bonds with other elements? explain your answer.

koban [17]

Argon atoms would not tend to make bonds with other atoms since it is classified as a noble atom which means it has a complete filled subshells. It does not have any electrons that are available for bonding. Noble gases belong to the Group 8A in the periodic table of elements. All of the elements in this group do have a complete or filled electron orbitals which makes them so stable or the s and p outer electron shells are complete with electrons. All of them follows the octet rule. Thus, they do not need any sharing or transfer of electrons from other compounds for them to be more stable.

Explain how the ecosystem that you selected follows the law of conservation of mass and the law of conservation of energy. It is

trasher [3.6K]

In the ocean, light is used by phytoplankton in order to produce sugar. 10% of the energy from the sun is available to the zooplankton that eat the phytoplankton, the rest of the energy is lost as heat or through powering body building/functions/reproduction. Whatever eats the zooplankton receives 10% of that energy in order to grow

In a recent Grand Prix, the winner completed the race with an average speed of 299.8 km/h. What was his speed in miles per hour,

scoundrel [369]

Answer :

(a) The speed is, 186.287 mi/hr

(b) The speed is, 83.277 m/s

(c) The speed is, 273.22 feet/s

Explanation :

(a) We are given the speed is, $299.8km/hr$

As we know that,

$1km=\frac{1}{1.60934}mi$

By using both the conversion, we get:

$299.8km/hr$

$\Rightarrow \frac{299.8km}{1hr}\times \frac{1mi}{1.60934km}$

$\Rightarrow 186.287mi/hr$

The speed is, 186.287 mi/hr

(b) We are given the speed is, $299.8km/hr$

As we know that,

$1km=1000m$

and,

$1hr=3600s$

By using both the conversion, we get:

$299.8km/hr$

$\Rightarrow \frac{299.8km}{1hr}\times \frac{1000m}{1km}\times \frac{1hr}{3600s}$

$\Rightarrow 83.277m/s$

The speed is, 83.277 m/s

(c) We are given the speed is, $299.8km/hr$

As we know that,

$1km=3280.84feet$

and,

$1hr=3600s$

By using both the conversion, we get:

$299.8km/hr$

$\Rightarrow \frac{299.8km}{1hr}\times \frac{3280.84feet}{1km}\times \frac{1hr}{3600s}$

$\Rightarrow 273.22feet/s$

The speed is, 273.22 feet/s
