False you should never taste something if you don’t know what it is
Ca<span>2+</span> is less electro-positive than Mg2+. Therefore, CaO is less ionic than MgO. and in turn means that the O in CaO is more like O<span>2<span>– will react with H in H2O more so than O2- of MgO, because it is more ionic means O is strongly bonded to Mg compare to Ca</span></span>
We can approach this problem using the ideal gas law which is as follows:
PV = nRT
P = pressure
V = volume
n = number of moles
R = gas constant, 0.08206 Latm/Kmol
T = temperature
We are asked to solve for temperature and can rearrange the equation to solve for T:
PV = nRT
T = PV/nR
Now we simply plug in the data to solve for T:
T = (4.50 atm)(10.0 L)/(3.00 mol)(0.08206 Latm/Kmol)
T = 183 K
The temperature of the gas is 183 K.
Answer:
3.39 * 10^-41 m
Explanation:
Given that:
speed of airplane = 880 km/hr
Mass of airplane = 80000 kg
Debroglie wavelength (λ) = h / mv
h = planck's constant = 6.626 * 10^-34
; mass = 80000kg
Velocity = 880km/hr to convert to m/s
Velocity = (880 * 1000m) / 3600 =244.44 m / s
λ = (6.626 * 10^-34) /(80000*244.44)
λ = (6.626 * 10^-34) / 19555200
λ = 3.3889 *10^-41
λ = 3.39 * 10^-41 m
