The answer is 101 kPa or 14.70 pound-force per square inch.
Answer:
Boron
Explanation:
(a)
H means hydrogen
The atomic mass of hydrogen is 1 and the mass number is 2.
Be means beryllium
The atomic number is 4 and the mass number is 9.
n mean neutron, atomic number is 0 and mass number 1.
By conserving the charge,
the atomic number of X = 1 + 4 - 0 = 5
the mass of X = 2 + 9 - 1 = 10
The element having atomic number 5 and mass number 10 is Boron (B).
Answer:

Explanation:
*Assume the parallel disks have equal diameters.
Given the electric strength as
transferring
electrons, the disk's Area can be calculated using the formula:

#We now calculate the disks diameter:

Hence, the diameter of the disks is

Some of the scientific questions that may be answered through the experiment are:
(1) What are the physical changes that may occur in the solution or the indicator when added with acidic/basic solution?
(2) How much of the indicator is needed in order to bring about a significant physical change in the solution to identify its H+ concentration?
