Calculate the number of moles in 136g of ammonia

Chemistry
1 answer:
amm18123 years ago
6 0

Answer:

8moles

Explanation:

We are given the mass of ammonia to be 136g

  Ammonia = NH₃  

Let us find the number of moles in ammonia;

 Number of moles  = \frac{mass}{molar mass}  

  Molar mass of ammonia = 14 + 3(1) = 17g/mol

so;

   Number of moles  = \frac{136}{17}   = 8moles

statuscvo [17]

Answer:

D. Hydrogen bonds between complementary base pairs89

Explanation:

A DNA molecule is composed of two long polynucleotide chains made of four types of nucleotide subunits, two purines (adenine and guanine) and two pyrimidines (cytosine and thymine). These nucleotides are joined by covalent bonds forming a phosphate-sugar backbone. <em>These strands are held to one another with hydrogen bonds between the base portions of complementary nucleotides.</em>

What is the change in internal energy ( ΔU ) of the system if q = –8 kJ and w = –1 kJ for a certain process?
Radda [10]

Answer:

Change in internal energy (ΔU) = -9 KJ

Explanation:

Given:

q = –8 kJ [Heat removed]

w = –1 kJ [Work done]

Find:

Change in internal energy (ΔU)

Computation:

Change in internal energy (ΔU) = q + w

Change in internal energy (ΔU) = -8 KJ + (-1 KJ)

Change in internal energy (ΔU) = -8 KJ - 1 KJ

Change in internal energy (ΔU) = -9 KJ
