Answer:
10.304 kPa
Explanation:
n=mol nitrogen (N2) gas=2moles
Temperature=T=310 K
Volume=0.5 L=0.5 dm3
R=8.31 J K−1 mol−1
From Gerenal gas equation we know that
PV=nRT
P=nRT/V
Putting the values
P=(2*8.31*3100/(0.5)
P=10.304 kPa
or P=10304 Pa
The answer is (1) CaCO3. The bond between C and O is covalent bond. And the bond between Ca2+ and CO3 2- ion is the ionic bond. So the compound CaCO3 satisfy this condition.
Answer:
D. B, C, A
Explanation:
A. For object A, given the following data;
Mass = 2kg
Net force = 1N
To find the acceleration;
Acceleration = net force/mass
Acceleration = 1/2
<em>Acceleration = 0.5m/s²</em>
B. For object B, given the following data;
Mass = 8kg
Net force = 10N
To find the acceleration;
Acceleration = net force/mass
Acceleration = 10/8
<em>Acceleration = 1.25m/s²</em>
C. For object C, given the following data;
Mass = 7kg
Net force = 7N
To find the acceleration;
Acceleration = net force/mass
Acceleration = 7/7
<em>Acceleration = 1m/s²</em>
Therefore, placing the objects in decreasing order, according to the magnitude of the acceleration they are experiencing is B, C, A
