Generating electricity from solar panels produce no greenhouse gases whatsoever, and so can help to reduce the effect of climate change if used widely. With solar energy powering a home or business, these is no burning of fuel and no emissions from energy production.
Answer:
0.0022369 mph
Explanation:
a snail crawls at a rate of 0.10 cm/s
1mile = 5280 ft
Scientifically 1 cm/s = 0.022369 mph
therefore 0.10cm/s = 0.10cm/s x 0.022369 mph = 0.0022369 mph
The equation of the reaction is:
Na2CO3 + AgNO3 → NaNO3 + Ag2CO3
but this equation, not a balanced equation so let's make it a balanced equation:
- we will start with Na number of atoms, we should make the Na atom number is equal on both sides.So we put 2 NaNO3 instead of NaNO3
- and then the Ag atom, we put 2AgNO3 instead of AgNO3 to make the number of Ag on each side are equals.
So the final balanced equation for this reaction is:
Na2CO3(aq) + 2AgNO3(aq) → 2NaNO3(aq) + Ag2CO3(s)
SO know we have number of Na on each side = 2
number of Ag on each side = 2
<span>Aluminum foil is a metal so it has the typycal properties of metals. These are the three most representative properties of metals that aluminum foil exhibit:
</span>
<span /><span /><span>
</span><span>1) It is good conductor of electricity: this property is consequence of the metallic bond, which permits that the outermost electrons of each atom can flow through the entire network of atoms conducting the electricity.
</span>
<span /><span /><span>
</span><span>2) Is is good conductor of heat: this other property of metals is due to transmission of vibration that is carried out between neighboring atoms.
</span>
<span /><span /><span>
3) it is ductile: this property means that the metals can be formed into foils.
</span><span />
<span>Other properties that can be mentioned are: solid at room temperature and mallealble (can form wires)
