Answer:
The answer to your question is:
Explanation:
a)
Metals: are shiny, malleable and ductile, they can conduct electricity and heat, form cations in aqueous solutions.
Nonmetals: non-lustrous, brittle, not good conductors of heat and electricity, form anions in aqueous solutions.
b)
Metals are located in the left side of the periodic table
Nonmetals are located in the right side of the periodic table.
c)
Metal are use to make pans because they are good conductors of heat and also are malleable and ductile.
Nonmetals are used to make sleeping bags and coolers because they do not conduct heat so they can isolate matter.
Answer:
Explanation:
Groundwater is stored in the open spaces within rocks and within unconsolidated sediments. Rocks and sediments near the surface are under less pressure than those at significant depth and therefore tend to have more open space. For this reason, and because it’s expensive to drill deep wells, most of the groundwater that is accessed by individual users is within the first 100 m of the surface. Some municipal, agricultural, and industrial groundwater users get their water from greater depth, but deeper groundwater tends to be of lower quality than shallow groundwater, so there is a limit as to how deep we can go.
<h3>Answer:</h3>
Phosphoric acid reacts with magnesium hydroxide to produce magnesium phosphate and water via the following reaction:
2H3PO4 + 3Mg(OH)2 → Mg3(PO4)2 + 6H2O
(solid) (solid) (solid) (liquid)
<h3>Explaination:</h3>
This is a typical neutralization reaction of an acid with a base to form a salt and water. The reaction is exothermic, gives off heat,
ΔH < 0 , and may be balanced by adding balancing numbers in front, ie adding molecules, in order to ensure that the total number of atoms of each element is the same on the left and right hand sides of the equation.
Doing so we obtain :
2H3PO4 + 3Mg(OH)2 → Mg3(PO4)2 + 6H2O
(solid) (solid) (solid) (liquid)
