Answer:
I notice that it's extremely hot after it has been sitting in thr sun for a while. The sun's rays have been directly shining on the car because the car was in the sun's Ray's directly. If the car's windows were to be left open, it would be less hot but still be hot if the rays of the sun were directly on the car.
Answer:
Homologous series is defined as a systematic order of structurally similar organic compound containing same functional group in their family and two adjacent members differ in their molecular formula by -CH2 unit.
Characteristics:
1.Various members of homologous series contain same functional group.
2.Various members of homologous series can be represented by common formula.
3. All members of a homologous series have almost similar chemical properties.
4. All members have common method of preparation.
5.Two successive members of homologous series have different chain length or difference in their molecular formula by -CH2 unit.
6.The members of homologous series show different physical properties.
The answer is deformation of rocks. hope it helps :)
Answer:
$182 is the value of the gold in the coin
Explanation:
Diameter is 2r, the ratio of the coin is = 1.62cm / 2 = 0.81cm
Following the formula of the volume of the coin:
V = π r² h
V = π*(0.81cm)²*0.085cm
V = 0.172cm³ = mL
As the density of the gold is 19.32g/mL, the mass of 0.1752mL of gold is:
0.1752mL * (19.32g / mL) =
3.385g is the mass of the coin
As the price of the gold is $53.90 / g, the value of the gold in the coin is:
3.385g * ($53.90 / g) =
<h3>$182 is the value of the gold in the coin</h3>
SO3+H2O-->H2SO4
If you need their states
SO3(g) + H2O(l) --> H2SO4(aq)
And they're already balanced
