Yes or no? Do the following have co2 emissions? Coal Oil Natural Gas Nuclear Power Biofuel Hydropower Geothermal Wind Energy Solar Energy Hydrogen
green house effect is correct (gradpoint)
I just took the quiz and the answer is D.)wind flow and temperature
Which is an example of transforming potential energy to kinetic energy? Check all that apply. changing thermal energy to electrical energy changing chemical energy to thermal energy changing nuclear energy to radiant energy changing radiant energy to electrical energy changing mechanical energy to chemical energy
Earth's core is composed of two separate layers the inner core and the outer core what is one difference between these two layers? F. One is orphans one is zinc G. One is liquid and one is gas H. One is solid and one is liquid I. One is iron and one is nickel
Answer: Option (b) is the correct answer.
Plasma is a hot ionized gas that contains approximately equal number of both positive ions and negatively charged electrons.
Thus, we can conclude that if a substance containing charged ions and electrons can be compressed so that the particles have less space between them, the substance is a plasma.
Crustal plates scrape and slide past each other along faults at their boundaries. For example, the Pacific and North American Plates slide past each other along the San Andreas Fault in northern California. What natural hazard usually results when crustal plates scrape and slide past one another? A. hurricanes B. tsunamis C. tornadoes D. earthquakes 50 POINTS!
The answer is D I just took the test on study island
and there is an explanation
When crustal plates scrape and slide past one another, they release built-up energy. This energy travels through the Earth as earthquakes.
hope this helps you
(0.544881 mol C) × (12.01078 g C/mol) = 6.54445 g C
(4.91 g H2O) / (18.01532 g H2O/mol) × (2 mol H / 1 mol H2O) = 0.54509 mol H
(0.54509 mol H) × (1.007947 g H/mol) = 0.54942 g H
10 g total - 6.54445 g C - 0.54942 g H = 2.90613 g O
(2.90613 g O) / (15.99943 g O/mol) = 0.18164 mol O
Divide by the smallest number of moles:
(0.544881 mol C) / 0.18164 mol = 2.9998
(0.54509 mol H) / 0.18164 mol = 3.0009
(0.18164 mol O) / 0.18164 mol = 1.0000
Round to the nearest whole number to find the empirical formula:
The difference between temperature and thermal energy is that temperature measures the average kinetic speed of molecule and thermal energy is the total kinetic energy of all particles in a given substance.
and since, V = IR
you also have
P = I^2 R P = V^2 / R
What happens when the electron moves from the first energy level to the second energy level? Energy is absorbed, and an emission line is produced. Energy is released, and an emission line is produced. Energy is absorbed by the atom. Energy is lost from the atom.
Emission lines occur only in the case of transitions from higher to lower energy levels in which energy is emitted.
The water has potential energy when it is at the top of the falls which is converted into kinetic energy as it falls.
Which of the following might be considered a viable application of a radioactive tracer? It can be more then one? A) adding a stream of radioisotopes to waste water to examine where pollution goes when it flows into the ocean B) embedding a radioactive plug in a valuable necklace so that its location can be determined using a Geiger counter C) placing radioactive sources around a room to trace the location of people as they move through the room d.) filling a pipeline with radioactive gas to see if it contains any leaks
Which of the following is true of both nuclear fusion and nuclear fission? a. They both require a high energy input. b. They both occur without byproducts. c. They both have a high energy output. d. They both involve large atoms breaking into smaller atoms.
Both processes release tremendous amounts of energy.
B. Greater energy
Fast moving water is very energetic as its can displace very large rocks, boulders and make pebbles and sand out of them through the process r erosion. Fast moving water have kinetic energy, it opposes anything that come in its way. As river make its own channel by eroding plane. Many antecedent rivers have make their channel by cutting large mountains too.
A gas has an initial volume of 212 cm^3 at a temperature of 293 K and a pressure of 0.98 atm. What is the final pressure of the gas if the volume decreases to 196 cm^3 and the temperature of the gas increases to 308 K? a. 0.86 atm b. 0.95 atm c. 1.0 atm d. 1.1 atm
P1V1/T1 = P2V2/T2
in this equation we know:
P1,V1 and T1, T2 and V2.
We have one equation and 1 unknown variable.
P2 = T2P1V1/T1V2 = 1.1atm
When an electric current is passed through water during the process of electrolysis, two gases are formed. One gas has a boiling point of -183 degrees celsius and the other has a boiling point of -253 degrees celsius. Has a physical change or a chemical change occurred? Explain.
your question is incomplete, please consider revising it.
Gas is confined in a tank at a pressure of 11.0 atm and a temperature of 25.0 degrees C. If two-thirds of the gas is withdrawn and the temperature is raised to 75.0 degrees C, what is the new pressure of the gas remaining in the tank? Please help!
