Answer:
The compound amount is $303.03 .
Explanation:
Formula for compound interest:
Principle amount = $1100
Rate of the interest compounded semiannually :
= R = 9% = 0.09
Number of times interest compounded, n = 
(semi means two times in a year)
Time period = T = 14
The compound amount is $303.03 .
Answer:
It is the portion of internal energy that can be transferred from one substance to another.
Explanation:
Thermal energy is the energy obtained by an object due to the motion of its particles.
It is also known as internal energy as it is the energy within the particles due to their motion.
Therefore, we can conclude that it is the portion of internal energy that can be transferred from one substance to another.
Hope this helps!
Answer:
547.5g
Explanation:
To get the mass, you need moles.
moles = (molarity)(Liters)
moles = (1.230M)(4.200L) = 5.166 moles Na2CO3
Now, just use stoichiometry
molar mass of Na2CO3 = 2(mass of Na) + (mass of C) + 3(mass of O)
= 2(22.9) + 12.01 + 3(16) = 105.99g/mol
5.166moles(105.99g/mol)
= 547.544
But, the measurements given had 4 significant figures, so in chemistry we write:
547.5g
The Bohr model proposed that electrons could just have characterized vitality levels thus when rotting back to a lower vitality level discharge a specific measure of vitality. Since the measure of vitality could be changed over to a specific recurrence then particular emanation lines were found in the electromagnetic range. Alternate speculations couldn't clarify the discharge lines.
