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
As we know,
pH + pOH = 14
Or,
pOH = 14 - pH
Putting Value of pH,
pOH = 14 - 10.62
pOH = 3.38
pOH is converted into [OH⁻] as follow,
[OH⁻] = 10⁻pOH ∴ -pOH is in power, 10 means antilog

[OH⁻] = 10⁻³°³⁸
[OH⁻] = 0.0004168
[OH⁻] = 4.16 × 10⁻⁴
Answer:
d
Explanation:
Aluminium and Indian are in the same group/family
Sodium and Sulfer are in the same period
Elements of the same family have similar properties
Since sulfur and sodium aren't in the same family they dont share properties
Answer:
3.4 mol Li2SO4
Explanation:
6.8 mol LiOH × (1 mol Li2SO4/2 mol LiOH)
= 3.4 mol Li2SO4
