Answer:
311.25k
Explanation:
The question assumes heat is not lost to the surroundings, therefore
heat emitted from hotter sample ( 
)= heat absorbed by the less hotter sample( 
)
The relationship between heat (q), mass (m) and temperature (t) is 
where c is specific heat capacity, 
temperature change.
= 
equating both heat emitted and absorb
where the values with subset 1 are the values of the hotter sample of water and the values with subset 2 are the values of the less hot sample of water.
C will cancel out since both are water and they have the same specific heat capacity.
so we have
where m1 = 50g, t 1initial = 330, m2 = 30g, t2 initial = 280,t final (final temperature of the mixture) = ?
-50 * (
- 330) = 30 * ( - 280)
-50 + 16500 = 30 - 8400
80 = 16500+8400
80 = 24900
= 24900/80 = 311.25k

This immense mountain range began to form between 40 and 50 million years ago, when two large landmasses, India and Eurasia, driven by plate movement, collided. Because both these continental landmasses have about the same rock density, one plate could not be subducted under the other.Mar. 9, 2015
Answer:
<h2>ATP, RNA, NAD and DNA.</h2>
Explanation:
A nitrogenous base; it is an organic molecule containing a nitrogen, carbon and other atoms that has the chemical properties of a base that is why they are called as bases. The nitrogenous bases are; i) adenine, ii) guanine, iii) thymine, iv) uracil and v)cytosine.
Adenine is a nitrogenous base which is found in ATP, RNA. NAD, FAD and DNA. adenine pairs with thymine in DNA synthesis.
