Answer:
3
Explanation:
there are 3 different elements in sugar. just add up all the letters you see
Thermal energy equation is;
Q = mcΔθ
Q = Thermal energy
m = mass
c = specific heat
Δθ = Temperature difference
the hot cup of coffee has a higher temperature. But the mass of coffee is very low compared to the mass of water in swimming pool. The maximum temperature for coffee only can go up to 100 ⁰C since the boiling point of water is 100 ⁰C. But the mass of water in swimming pool is very large and the thermal enegy is very high compared to the coffee cup due to that reason.
Answer:
0.84kg of gatorade powder
Explanation:
From the question given, we were told that 0.6kg of gatorade powder required 5 gallons of water.
To obtain the mass of gatorade needed for 7 gallons of water, we simply do the following:
0.6kg of gatorade powder required 5 gallons of water.
Therefore, xkg of gatorade powder will require 7 gallons of water i.e
xkg of gatorade powder = (0.6 x 7)/5
xkg of gatorade powder = 0.84kg
Therefore, 0.84kg of gatorade powder will be required.
Answer:
The answer to your question is letter d
Explanation:
If we remember there is a limit of electrons that can be place in a sublevel
Sublevel s only accept 2 electrons
Sublevel p only accept 6 electrons
Sublevel d only accept 10 electrons
Sublevel f only accept 14 electrons
This is in agreement wth the levels of energy, that only accept a determine number of electrons
Level Sublevel # of electrons
1 s 2
2 s and p 8 (2 + 6)
3 s, p and d 18 (2+6+10)
4 s, p, d, f 32 (2+6+10+14)
5 s, p, d,f 32 (2+6+10+14)
6 s, p, d 18 (2+6+10)
7 s, p 8 (2+6)
