Answer:
The oceans atmosphere. AKA Water.
Explanation:
The oceans and the atmosphere are the two large reservoirs of water in the Earth's hydrologic cycle. The two systems are complexly linked to one another and are responsible for Earth's weather and climate. The oceans help to regulate temperature in the lower part of the atmosphere.
Earth's atmosphere get warm up by the temperature absorbed by the gases in the atmosphere. However it can balanced water in earth such as ocean currents and cooling.
What is ocean currents?Ocean currents are formed from the pressure difference in ocean level and thus in day time there will be winds from ocean to land which cools the earth's surface.
Surface of the earth warms up by absorption of heat energy from sun. This warming will be higher if there are more greenhouse gases such as carbon dioxide, methane oxides of nitrogen, Sulphur etc.
Greenhouse gases intensely absorbs the temperature from radiation and thus increase the temperature of earth's surface. These gases are mainly evolved to the atmosphere by industries and factories.
Other factor which affects the temperature of earth surface include wind, ocean level etc. The level of ocean and ocean currents helps to regulate the temperature of the surface and make it cool.

It has been an expense for the Australian government (taxpayers) to try to control the rabbit population
Question 4 options:
True
False
Answer:
true
Explanation:
It has been an expense for the Australian government (taxpayers) to try to control the rabbit population. This statement is true.
Why did the rabbit population grow so quickly in Australia?Aside from the lack of natural predators on the continent, their success is aided by rapid reproduction: They can have more than four litters a year, each with up to five kits (baby rabbits).
The European wild rabbit has become an invasive pest in the southern two-thirds of Australia. They have an impact on natural environments, primary production, as well as townships and infrastructure.
The government turned to biocontrol in the 1950s. They released rabbits infected with myxoma, a virus that only affects rabbits, into southeastern Australia.
Thus, It has been an expense for the Australian government (taxpayers) to try to control the rabbit population. This statement is true.

why is it important that the level of the sea water does not go above the level of the filter paper
Answer:
The water (the substance) that passes through the filter paper is called the filtrate. If your mixture is a solution, such as salty water, then filtering will not separate the salt from the water. Instead, by heating the soluton the solvent (water) evaporates leaving the solid (salt) behind.

What is R in the ideal gas law equation?
A. The kinetic energy of the gas
B. The number of moles of the gas
C. The molar mass of the gas
D. The ideal gas constant
SUBMIT
Answer:
D
Explanation:
The ideal gas law is: pV = nRT, where n is the number of moles, and R is universal gas constant. The value of R depends on the units involved, but is usually stated with S.I. units as: R = 8.314 J/mol·K

Answer: [tex]C_3H_8+5O_2\rightarrow 3CO_2+4H_2O[/tex]
Explanation:
According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
The balanced chemical equation for combustion of propane will be :

Consider the following reaction, which occurs at standard state:
2CI(g) -- CI2(g) H= -243.4 kJ
If 15.0g of CI is concerted to chlorine, determine the heat released from this reaction.
Answer:
The heat energy released from the reaction is approximately 51.4791 kJ
Explanation:
The given parameters are;
The heat of the reaction of 2Cl (g) → Cl₂ (g) = -243.4 J
The given mass of Cl being converted to chlorine gas, Cl₂ = 15.0 g
From the reaction for the heat of formation, we have;
2 moles of chlorine produces 1 mole of Cl₂ to release 243.4 kJ of energy per mole of Cl₂
The mass of 1 mole of Cl ≈ 35.453 g
Therefore, from number of moles, n = Mass/(Molar Mass), we have;
The number of moles of chlorine, in 15.0 g of chlorine = 15.0/35.453 ≈ 0.423 moles
Therefore, given that 2 moles of Cl produces 1 mole of Cl₂, we have;
0.423 moles of Cl will produce 0.423/2 ≈ 0.2115 moles of Cl₂
The heat energy released from the reaction is therefore, H ≈ 0.2115 × 243.4 kJ = 51.4791 kJ.

which diagram would it be?
Answer:
2CH4 ------> 3H2 + C2H2
Explanation:
The law of conservation of mass states that atoms can neither be created nor destroyed in a chemical reaction.
The implication of this law is that the number of atoms of each element on the reactant side must be equal to the number of atoms of each element on the product side.
This law is only obeyed by the reaction, 2CH4 ------> 3H2 + C2H2
There were eight atoms of H on the left hand side as well as the right and side of the reaction equation. There were two atoms of C on both the left and right hand sides of the reaction equation respectively. Hence, the law was obeyed here.
