Answer: The amount of heat energy in joules required to raise the temperature is 526 Joules
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 = ?
m= mass of substance = 7.40 g
c = specific heat capacity = 
Initial temperature of the water = 
= 29.0°C
Final temperature of the water = 
= 46.0°C
Change in temperature ,
Putting in the values, we get:
The amount of heat energy in joules required to raise the temperature is 526 Joules
The numbers are both prime numbers.They both have 2 factors.
1x3=3. 1x5=5
3x1=3. 5x1=5
Answer:
Explanation: Does any of this look right? To be honest I just looked it up.
Answer : Option A) the arrangement of bonded atoms.
Explanation : A structural formula of certain molecule depicts the way the atoms are arranged in that particular molecule in any polyatomic species. It helps in deciding the chemical properties of that polyatomic molecule.
Answer: The correct answer is crude oil is a mixture of many organic compounds that need to be isolated to be used.
Explanation:
Crude oil is a naturally occurring petroleum product which is unrefined. It consists of various hydrocarbon deposits and organic compounds.
The refining of crude oil is important because it yield some important compounds that can be used in various purposes.
The refining of crude oil produces products such as gasoline, petrol, diesel and various other forms of petrochemicals which can be used on daily basis.
Hence, the correct statement is crude oil is a mixture of many organic compounds that need to be isolated to be used.
