Answer:Difference between Ceres and Pluto
Nestled in the asteroid belt between Mars and Jupiter, Ceres is a tiny loner, while Pluto — in the Kuiper Belt at the edge of the solar system — is nearly three times as big and hosts a handful of moons. A mixture of rock and water ice dominates Ceres' landscape, while methane and nitrogen ices cover Pluto

Answer:
2,93x10³atmL, 2,97x10⁵J
Explanation:
The work done in gas compression under constant pressure is:
W = -P×ΔV
<em>Where W is work done, P is pressure and </em>ΔV <em>is change in volume (Vol.f - Vol.i)</em>
Replacing:
W = -61.0atm×(51.0L - 99.0L)
W = 2928atmL = <em>2,93x10³atmL</em>
In Joules:
2928atmL × (101,325J / 1atmL) = 296680J ≡<em> 2,97x10⁵J</em>

Answer:
3.
Explanation:
- Al(OH)₃ reacts with HCl to produce AlCl₃ and water according to the balanced equation:
<em>Al(OH)₃ + 3 HCl → AlCl₃ + 3H₂O,</em>
<em></em>
<em>It is clear that 1.0 mole of Al(OH)₃ reacts with 3.0 mole of HCl to produce 1.0 mole of AlCl₃ and 3.0 moles of H₂O,</em>
<em />
<em>So, the coefficient of HCl is 3.</em>

Hello!
Fossil fuels are Carbon-based compounds that when heated in the presence of oxygen undergo a combustion reaction to produce thermal energy and gases. The chemical equation for the combustion of a generic Fossil Fuel (C) is the following:
C + O₂ →CO₂
From this chemical reaction, we can see that CO₂ (Carbon Dioxide) is produced, so the consumption of fossil fuels has increased the Carbon Dioxide concentrations in the atmosphere.
