Answer:
This energy drives the water cycle and makes life possible on Earth. The energy that Earth receives from the sun is absorbed by the atmosphere, geosphere, and hydrosphere. Then, the energy is changed into thermal energy. This thermal energy is then transferred through Earth's systems by convection and conduction.
Hope ur day's going great! Mark me as Brainliest if you dont mind <3
Explanation:
The first law<span> of thermodynamics is a version of the </span>law<span> of conservation of </span>energy<span>, adapted for thermodynamic systems. The </span>law<span> of conservation of </span>energy<span> states that the total </span>energy<span> of an isolated system is constant; </span>energy<span> can be transformed from one form to another, but cannot be created or destroyed</span>
Answer:
c) more particles collide with the walls of the container
Explanation:
More moles means more particles. If the volume remains the same, the collisions of more particles with the container walls cause the pressure to increase.
Answer:
<h2>572320 J</h2>
Explanation:
The potential energy of a body can be found by using the formula
PE = mgh
where
m is the mass
h is the height
g is the acceleration due to gravity which is 9.8 m/s²
From the question we have
PE = 730 × 9.8 × 80
We have the final answer as
<h3>572320 J</h3>
Hope this helps you
The percentage yield of the reaction : 93.3%
Mass of FeCO₃ 2310.44 g
<h3>Further explanation
</h3>
The reaction equation is the chemical formula of reagents and product substances
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products
Reaction
4 FeCO₃ + O₂ ⇒ 2 Fe₂O₃ + 4CO₂
MW FeCO₃ : 115,854 g/mol
MW Fe₂O₃ : 159,69 g/mol
mol of 1 kg Fe₂O₃ = 1000 g
mol of FeCO₃
mass of FeCO₃
a purity of 62.8%
