Answer:
The purpose of molecular modeling is to provide a three-dimensional image (either physical or software-based) that allows a chemist to better see the manner in which atoms and molecules can interact. These models can be used to interpret existing observations or to predict new chemical behavior.
Explanation:
It can describe shape and how they connect while forming the electrons.
According to the formula you have given us to work with . . .
1). The airplane's acceleration is
(80 m/s north - zero) / (20 sec) = 4 m/sec^2 north
2). For the cyclist:
(V-final - zero) / 20sec = 0.5 m/s^2 south
Multiply each side by 20s : V-final = 0.5 m/s^2 south x (20sec) =
10 m/s south
Answer:
C . 24 L
Explanation:
Given data:
Initial volume of gas = 20.0 L
Initial pressure of gas = 660 mmHg
Final volume = ?
Final pressure = 550 mmHg
Solution:
The given problem will be solved through the Boly's law,
"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"
Mathematical expression:
P₁V₁ = P₂V₂
P₁ = Initial pressure
V₁ = initial volume
P₂ = final pressure
V₂ = final volume
Now we will put the values in formula,
P₁V₁ = P₂V₂
660 mmHg × 20.0 L = 550 mmHg × V₂
V₂ = 13200 mmHg. L/ 550 mmHg
V₂ = 24 L
Answer: Jupiter.
Explanation: <u>Jupiter is the largest and most massive planet in the Solar System. Its mean radius, at 69,911 ± 6 km, makes it 10.97 the times the size of Earth, while its mass (1.8986×1027 kg) is the equivalent of 317.8 Earths.</u>
<u />
0.02375 moles
Explanation:
Fe2O3+CO :. Fe+CO2
We know that
56*2+16*3=160 gm of Fe2O3 can give 56 gm of Fe
So
3.8 gm can give 1.33 gm of Fe
It is equal to 1.33/56 moles of Fe which is equal to 0.02375 moles
