No it is redistributed and the state changes to gas and liquid
Answer: The four main categories of mineral formation are: (1) igneous, or magmatic, in which minerals crystallize from a melt, (2) sedimentary, in which minerals are the result of sedimentation, a process whose raw materials are particles from other rocks that have undergone weathering or erosion, (3) metamorphic, in which
Explanation:
Explanation:
The best way to separate the mixture is by using a bar magnet. We explore the magnetic property of the iron fillings in the mixture to separate it out.
- The mixture is spread out thinly on a flat surface.
- A bar magnet is hovered above the spread of the mixture
- The magnet attracts the iron fillings to itself
- This will leave the salt behind in the mixture.
Answer:
Magnesium is the most reactive element. it is higher than the other elements (Fe, Pb, Zn) in the electrochemical series
Answer:
1514g of CO₂ reacted
Explanation:
Based on the reaction:
2CO₂ + 43.9kJ → 2CO + O₂
<em>2 moles of carbon dioxide require 43.9kJ of energy to produce 2 moles of carbon monoxide and 1 mole of oxygen</em>
<em />
To solve this question, we must convert the 755kJ of energy to moles of carbon dioxide that reacts and to find the mass as follows:
755kJ * (2 moles CO₂ / 43.9kJ) =34.4 moles of CO₂ are produced
<em>Mass CO₂: Molar mass: 44.01g/mol</em>
34.4 moles CO₂ * (44.01g / mol) =
<h3>1514g of CO₂ reacted</h3>
