Answer: The temperature rise is 
Explanation:
The quantity of heat required to raise the temperature of a substance by one degree Celsius is called the specific heat capacity.
Q = Heat absorbed by ice = 5280 J
m = mass of ice = 2.40 kg = 2400 g (1kg=1000g)
c = heat capacity of water = 
Initial temperature = 
Final temperature = 
Change in temperature ,
Putting in the values, we get:
Thus the temperature rise is

Atoms are the unit of the molecule of the compound. The 3.01 x 10²⁴ atoms of oxygen are present in 5 moles of water and 3 moles of carbon dioxide in the sample.
<h3>What are atoms?</h3>
Atoms are the smallest fundamental unit of the compounds that can be given by Avogadro's number.
For calculating the oxygen atoms in 5 mole water:
If 1 mole = 6.02 × 10²³
Then, 5 moles = 5 × 6.02 × 10²³
Hence, 3.01 x 10²⁴ atoms of oxygen are present in 5 moles of water.
Moles of carbon dioxide in the sample is calculated as:
If 1 mole of carbon dioxide = 6.02 × 10²³ molecules
Then moles in 1.8 x 10²⁴ molecules will be,
(1.8 x 10²⁴ molecules) ÷ (6.02 × 10²³ molecules) = 3 moles
Hence, 3 moles of carbon dioxide is present in the sample.

Answer:
pharynx > larynx>trachea> bronchi>alveoli (so B)
Explanation:
nasal cavities (or oral cavity) > pharynx > trachea > primary bronchi (right & left) > secondary bronchi > tertiary bronchi > bronchioles > alveoli (site of gas exchange)
Answer:
The metal is most likely Sodium.
Explanation:
Iron is not soft enough to be cut with a knife and will not react violently with water. When Iron reacts with water it just slowly rusts.
Copper is somewhat malleable, however, does not really react with water and only forms an oxide layer in the air.
Sodium is soft enough to be cut with a knife (I know this because I have worked with it and seen people work with it). It is also an alkali metal which are known to explode when in water.
Gold is malleable but does not really react with anything and is considered inert.
