Answer: Vander waals
Explanation:
Tellurium is a chemical element with atomic number 52. It's symbol is Te.
Nitrogen is a chemical element with atomic number 14. Its symbol is N
VANDER WAALS bond is found between Nitrogen and Tellurium, just as in Tellurium(II) Nitrogen.
This bond is relatively weak compared to some other kinds of bonds.
That is why tellurium and most of its compounds are usually brittle and easily grounded.
So, Vander Waals bonds is the answer

A) 0.875 M of MgBr2 is 0.875 mol/L
B) 23.7 mL = 0.0237 L
0.875 mol => 1 L
x mol => 0.0237 L
Cross multiply
1x = 0.875 × 0.0237
x = 0.0207 mol
>> In 23.7 mL of 0.875 M MgBr2 solution there is 0.0207 moles of MgBr2
C) Molar mass of MgBr2 (*) = 24.305 + (2 × 79.904) = 184.113 g/mol
184.113 g => 1 mol
x g => 0.0207 mol
Cross multiply
1x = 184.113 × 0.0207
x = 3.8111 g
>> 0.0207 moles of MgBr2 is equivalent to 3.81 g of MgBr2
>> In 23.7 mL of 0.875 M MgBr2 solution there is 3.81 g of MgBr2
(*) Use your periodic table
U gotta know the atom numbers of each all 161/100=m/…. Well we have to know the capacity of CCl4 to do this question how many moles do we have ? Let’s say 1 okay then m will be 1.61 After finding it we are gonna add 79.35g
79.35+1.61=80.96 hope that it helped ;)
Answer:
Trabalho realizado por máquina térmica = 250 J
Explanation:
Dado
Eficiência da máquina térmica = 5% = 0,05
A eficiência é igual à proporção do trabalho realizado pela máquina térmica para o calor fornecido a ela
Por isso,
0,05 = Trabalho realizado por máquina térmica / 5000 J
Trabalho realizado por máquina térmica = 5000 J * 0,05 = 250 J
