The answer is D; Mass and Velocity
Answer:
Salicylic acids are clear white needle shaped crystal in room temperature and are used in pharmaceutical industries to produce analgesic.
Explanation:
- Salicylic acids are aromatic organic compound also known as monohydroxybenzoic acid which is lipophilic in nature.
- the physical properties are :
- they are colorlesss and odourless at room temperature.
- boiling point is 211°C and melting point is 315°C
- they are poorly soluble in water
- its saturated solution has pH of 2.4
- the chemical properties are:
- acytylation of hydroxy group in salicylic acid gives acytylsalicylic acid which is used as aspirin.
Answer:
3120.75J
Explanation:
So, we have the formula 
. For this example, q is the heat energy in Joules, m is the mass in grams, c is the specific heat capacity in 
, and 
t is the change in temperature. In this case, m = 47.5g, c = 0.9 , and t = 94-21 = 73°C. Plugging in the values, we get the joules of heat required to raise 47.5g of Al from 21°C to 94°C which is stated above. You can double check my answer but that should be it. An important thing to be aware of are the units. Sometimes, the heat capacity may not be . I may be in Kelvin or something. Anyways, hope this helps.
Answer is periodic because only happens in certain times
