Answer: The answer to your question is D) Strong nuclear force
Explanation:
In nature, there are four fundamental interactions: electromagnetism, gravitation, weak nuclear force and strong nuclear force.
The Strong nuclear force is responsible for binding protons and neutrons to form a new nucleus.
Weak nuclear force is responsible for radioactive decay which means splitting nucleus.
Answer:
1. Double displacement reaction
2. Trisodium phosphate and potassium hydroxide
3. Sodium hydroxide and Potassium phosphate
Explanation:
1)
The given chemical reaction is as follows.
The balanced chemical reaction is as follows.
In the above reaction two reactants are exchange their cations. Therefore, it is a double displacement reaction.
2)
In the above reaction left side of the reaction is considered as reactants.
- Trisodium phosphate
- Potassium hydroxide
3)
In the above reaction right side of the reaction is considered as products.
- Sodium hydroxide
- Potassium phosphate.
It is true because it just is
Answer:
c.boron-11
Explanation:
The atomic mass of boron is 10.81 u.
And 10.81 u is a lot closer to 11u than it is to 10u, so there must be more of boron-11.
To convince you fully, we can also do a simple calculation to find the exact proportion of boron-11 using the following formula:
(10u)(x)+(11u)(1−x)100%=10.81u
Where u is the unit for atomic mass and x is the proportion of boron-10 out of the total boron abundance which is 100%.
Solving for x we get:
11u−ux=10.81u
0.19u=ux
x=0.19
1−x=0.81
And thus the abundance of boron-11 is roughly 81%.

F i think i pretty sure F!!!!!!!!
