Answer:
it stop burning because the gas surrounds itself
Answer:
37.18°C.
Explanation:
- The amount of heat absorbed by water = <em>Q = m.c.ΔT.</em>
where, Q is amount of heat absorbed by water (Q = 5.75 x 10⁵ J).
m is the mass of water (m = 2190 g).
c is the specific heat capacity of liquid water = 4.18 J/g°C.
ΔT is the temperature difference = (final T - initial T = 100.0°C - initial T).
∴ Q = m.c.ΔT = 5.75 x 10⁵ J.
5.75 x 10⁵ J = (2190 g)(4.18 J/g°C)(100.0°C - initial T)
∴ (100.0°C - initial T) = (5.75 x 10⁵ J)/(2190 g)(4.18 J/g°C) = 62.81°C.
<em>∴ initial T = (100.0°C - 62.81°C) = 37.18°C.</em>
Explanation:
Chromosomal DNA is packaged inside microscopic nuclei with the help of histones. These are positively-charged proteins that strongly adhere to negatively-charged DNA and form complexes called nucleosomes. Each nuclesome is composed of DNA wound 1.65 times around eight histone proteins.
