Answer: At convergent boundaries, plates move toward each other. They can push together and cause mountain ranges to form. At other times, one plate gets pushed down beneath the other plate. ... At divergent boundaries, plates move apart from each other.
Explanation:
I whould personally go with plates moved in closer
Explanation:
(a)
The given data is:-
Energy = 2391 Calories
The conversion of calories to J is shown below as:-
1 calorie = 4.184 J
So,
Energy = 4.184 * 2391 J = 10003.944 J
Answer in four significant digits: -
(b)
The conversion of calories to kJ is shown below as:-
1 calorie = 0.004184 kJ
So,
Energy = 0.004184 * 2391 kJ = 10.003944 kJ
Answer in four significant digits: -
(c)
The conversion of calories to kWh is shown below as:-
1 calorie = kWh
So,
Energy = kWh = 0.002778873 kWh
Answer in four significant digits: -
Carbon carbon triple bonds
Explanation:
Rate of the reaction ,k=
Half life of the
(first order kinetics)
Half life of the is 20,502.958 seconds.
Integrated rate equation for first order kinetics in gas phase is given as:
p= pressure of the gas at given time t.
= Initial pressure of the gas
(i) When, t = 50 sec
p = 500.49 Torr
(ii)When, t = 20 min = 1200 sec
p = 519.83 Torr
The formula for determination of atomic mass given the mass of isotopes and relative abundance is:
Ar = ∑(mass * abundance) / 100
Ar = (68.92558 * 60.108 + 70.92470 * 39.892) / 100
Ar = 69.72306
The atomic mass of gallium is 69.72306 amu
