Answer:
Explanation:
Hello,
In this case, given the reaction, the molar mass of ethene is 28 g/mol and the molar mass of carbon dioxide is 44 g/mol. With that information we compute the theoretical yield considering a 1:2 molar ratio respectively between them:
Thus, we compute the percent yield with the given grams of carbon dioxide:
Regards.
Answer:
wavelength = wave velocity/frequency.
Explanation:
c
is a constant. It is usually given as
3.00
×
10
8
m/s or
3.00
×
10
10
cm/s rounded to three significant figures.
Wavelength is measured in meters, centimeters, nanometers, etc...).
Frequency has a unit of
1/s
which means
1
cycle per second. It is also given the unit Hertz (Hz) in honor of German physicist Heinrich Hertz who proved the existence of electromagnetic waves.
1
Hz
=
1/s

Answer:
Oil, coal, natural gas, metals, stone and sand are natural resources. Other natural resources are air, sunlight, soil and water. Animals, birds, fish and plants are natural resources as well. Natural resources are used to make food, fuel and raw materials for the production of goods.
When a nuclear chain reaction in a mass of fissile material is self-sustaining, the mass is said to be a in a critical state in which there is no increase or decrease in power, temperature, or neutron population
There is only one stable atom that does not have neutrons. It is an isotope of the element hydrogen called protium. Protium, which contains a single proton and a single electron, is the simplest atom. All other stable atoms contain some number of neutrons.
