Scientists claim that climate change is happening because Earth is warming. They also claim that humans have helped cause the wa
LUCKY_DIMON [66]
Climate change has always happened on Earth, which is clearly seen in the geological record; it is the rapid rate and the magnitude of climate change occurring now that is of great concern worldwide. Greenhouse gases in the atmosphere absorb heat radiation. Human activity has increased greenhouse gases in the atmosphere since the Industrial Revolution, leading to more heat retention and an increase in surface temperatures. Atmospheric aerosols alter climate by scattering and absorbing solar and infrared radiation and they may also change the microphysical and chemical properties of clouds. Finally, land-use changes, such as deforestation have led to changes in the amount of sunlight reflected from the ground back into space (the surface albedo). It may seem counterintuitive, but
more snowfall during winter storms
is an expected outcome of climate
change. That's because a warmer
planet is evaporating more water
into the atmosphere. That added
moisture means more precipitation
in the form of heavy snowfall or
downpours.
During warmer months, this can
cause record-breaking floods. But
during the winter - when our part
of the world is tipped away from
the sun - temperatures drop, and
instead of downpours we can get
massive winter storms.

List the number of each type of atom on the left side of the equation 2C6H14(l)+19O2(g)→12CO2(g)+14H2O(g) Enter your answers sep
murzikaleks [220]

<u>Answer:</u> The number of carbon, hydrogen and oxygen atoms on the left side of the reaction are 12, 28 and 38 respectively

<u>Explanation:</u>

In a chemical equation, the chemical species are termed as reactants or products.

Reactants are defined as the species which react in the reaction and are written on the left side of the reaction arrow.

Products are defined as the species which are produced in the reaction and are written on the right side of the reaction arrow.

For the given chemical equation:

2C_6H_{14}(l)+19O_2(g)\rightarrow 12CO_2(g)+14H_2O(g)

On the reactant side:

Number of carbon atoms = (6 × 2) = 12

Number of hydrogen atoms = (14 × 2) = 28

Number of oxygen atoms = (2 × 19) = 38

Hence, the number of carbon, hydrogen and oxygen atoms on the left side of the reaction are 12, 28 and 38 respectively

Which of the following changes will decrease the total amount of gaseous solute able to be dissolved in a liter of liquid water?
Scrat [10]
A gaseous solute will <span> be able to be dissolve in a liter of liquid water by increasing the pressure of the gas. an example of this situation is the increase in solubility of carbon dioxide in sea water which turns it into an acidic environment for marines as pressure increases.</span>

Explain how swirling occurs in mixing​
TEA [102]

Explanation:

With respect to the mass transport mechanism in mixing, two fluids flow tangentially into the chamber and the radial component of velocity grows because fluids tend to flow through the outlet channel. These two components result in an overall rotating flow field inside the chamber
