Answer:
E. 1.18x10^4nm/ms^2
Explanation:
The aceleration of the train is given in m/s². We need to conver, first, the meters to nm and then, the seconds to ms as follows:
11.8m/s² * (1x10⁹nm / 1m) = 1.18x10¹⁰nm / s²
Now, as 1s is equal to 1000ms:
1.18x10¹⁰nm / s² * ((1s)² / (1000ms)²)) =
1.18x10⁴nm / ms²
Thus, right option is:
<h3>E. 1.18x10^4nm/ms^2</h3>
Answer:
option B
Explanation:
A spontaneous reaction drive favorable when enthalpy is decreasing and the entropy is increasing on the system. If that happens the reaction occurs spontaneously
Space -filling models are also known as Calotte models. These are 3 dimensional models that depict the spatial relationships between atoms.
The space-filling model of water molecule shows the 3 D structure of the water molecule. This model CLEARLY REVEALS THE OXYGEN ATOM WHICH IS LOCATED CENTRALLY WITH TWO HYDROGEN ATOMS IN THE ADJACENT SIDES. THE MODEL ALSO SUGGESTS HOW THE WATER MOLECULES ATTRACT EACH OTHER.
