Answer:
Final T = 64.0°C.
Explanation:
- The amount of heat absorbed by Na (Q) can be calculated from the relation:
<em>Q = m.c.ΔT.</em>
where, Q is the amount of heat absorbed by Na (Q = 1840 J),
m is the mass of Na (m = 68.0 g),
c is the specific heat capacity of Na (c = 1.23 J/g °C),
ΔT is the temperature difference (final T - initial T) (ΔT = final T - 42.0°C).
∵ Q = m.c.ΔT.
∴ (1840 J) = (68.0 g)(1.23 J/g °C)(final T - 42.0°C)
(final T - 42.0°C) = (1840 J)/(68.0 g)(1.23 J/g °C) = 22.0°C.
<em>∴ final T</em> = 22.0°C + 42.0°C = <em>64.0°C.</em>
Answer: 
Explanation:
Neutralization is a chemical reaction in which acid and base combine to form salt and water. Acids donate
ions and bases donate
ions in water which combine to form water molecules.
The balanced molecular equation is ;
Photosynthesis. animal cells can't carry out photosynthesis since they don't have chloroplasts.
Answer:
It should be silicon... I even googled it to see if I was correct and that’s what it says so can someone figure out why silicon is not an answer
