Answer:
12,375 cm³
Explanation:
v=l×w×h
Since there are 3 books the equation would then be
v=3(l×w×h)
v=3(25×15×11)
v=3(4,125)
v=12,375 cm³
1. Density=mass/volume=2kg/6m=0.33kg/m (convert to proper units)
2. Density=mass/volume=0.6kg/3L=0.2kg/L (convert to proper units)
3. Density=mass/volume= 129g / 30 cm (convert to proper units)
V=length*width*height=2*3*5 = 30
4. Volume (units) = cm^3 because, like in problem 3, Volume=width(cm)*length(cm)*height(cm)
However, when you pour liquid into a cylinder (so the volume would be the liquid), you measure it in mL.
5. Volume with rock - initial volume (without the rock) = Volume of rock
18.2-12.7= 5.5
Ionic bonds are formed as one atom the metal gives up or transfers one of its valence electron to the other atom that would then be able to accept it. This other atom is a non metal. This process occurs because the atoms want to become more stable by each of them satisfying the octet rule. In which atoms would have a maximum of 8 valence electrons.
Answer:
a. 
b. 
c. 
Explanation:
Hello,
a. By applying the given information, one obtains:
b. By knowing that the propane has a molecular mass of 44g/mol, one obtains:
c. Here, the propane's combustion chemical reaction is stated:
This enthalpy of reaction is computed via:
Δ
Finally, since it is done for 20 lb of propane (), the obtainable energy is:
Best regards.
Humidity, air temperature and pressure, wind speed and direction, cloud cover and type, and the amount and form of precipitation are all atmospheric characteristics of the momentary conditions we call weather. ... Differential warming, in turn, causes variations in the temperature and pressure of overlying air masses.
