Answer:
The balanced equation is given below:
UO2(s) + 4HF(l) —› UF4(s) + 2H2O(l)
The coefficients are: 1, 4, 1, 2
Explanation:
UO2(s) + HF(l) —› UF4(s) + H2O(l)
The above equation can be balance as follow:
There are 2 atoms of O on the left side and 1 atom on the right side. It can be balanced by writing 2 in front of H2O as shown below:
UO2(s) + HF(l) —› UF4(s) + 2H2O(l)
There are 4 atoms of F on the right side and 1 atom on the left side. It can be balanced by writing 4 in front of HF as shown below:
UO2(s) + 4HF(l) —› UF4(s) + 2H2O(l)
Now, the equation is balanced.
The coefficients are: 1, 4, 1, 2.

Answer: The correct answer is it emits light.
Explanation:
When an electron is present in ground level that is the lower energy level and moves to the higher energy level, the energy is provided to the electron which means that it absorbs light. This is known as absorption.
When an electron present in the higher energy level comes back to the lower energy level, it emits radiations in the form of light. This is known as emission.
Hence, the correct answer is it emits light.
Answer:
Explanation:
Use Avogadro’s number to convert formula units of RbNO₃ to moles of RbNO₃.
1 mol RbNO₃ ≡ 6.022 × 10²³ formula units RbNO₃
Moles of RbNO₃ = 2.41 ×1 0²⁴ × = 4.00 mol RbNO₃
There are of RbNO₃ in 2.41 × 10²⁴ formula units.
Apartheid was a legal racial separation system that ruled the Republic of South Africa from 1948 to 1993. Apartheid's mechanisms were in place before its creation, and South Africa is still dealing with these issues. Apartheid divided various races into different regions, and discrimination against people of color was not only acceptable, but also legal, with white people having full priority on housing, jobs, education, and political power. Even though South Africa was constantly chastised for the system, it wasn't until 1991 that the legal system of apartheid began to crumble, and it was finally brought down in 1993.
What is Apartheid?
Apartheid has been legally abolished, but whites and blacks continue to coexist in separate communities. There are still "black" and "white" neighborhoods, as well as "black" and "white" churches and restaurants. When the international media writes about Southern Africa, they almost always mention the country's "fading rainbow" and experiment in multi-ethnic democracy .
