Answer:
B. 0.302.
Explanation:
- To solve this problem, we can use the relation:
<em>Q = m.c.ΔT,</em>
where, Q is the amount of heat absorbed by water (Q = 0.954 J).
m is the mass of water (m = 0.755 g).
c is the specific heat capacity of water (c = 4.186 J/g.°C).
ΔT is the temperature difference (final T - initial T) (ΔT = ??? °C).
∴ ΔT = Q/m.c = (0.954 J)/(0.755 g)(4.186 J/g.°C) = 3.018 °C ≅ 3.02 °C.
1. Fill the balloon with water, then weigh it. The volume is then: Volume (cm^3) = Weight(gm)/1(gm/cm^3), (neglecting the weight of the empty balloon.)
It defines the element. If you change the protons, you change the type of element. A proton is positively charged and is most of the mass of the atom, next to the neutron. Neutrons have a very very very slightly higher mass.
The pH of the buffer that consists of 0.55 M HNO₂ is 3.3, which is acidic.

What is the common name for 0.55 M HNO₂?</h3>
The common name for 0.55 M HNO₂ is Nitrous acid. Only in solution, the gas phase, and in the form of nitrite salts is nitrous acid, a weak and monoprotic acid, known to science. Amines are converted into diazonium salts using nitrous acid. To produce azo colors, azo coupling processes use the resultant diazonium salts as reagents. A nitrogen oxoacid is a nitrous acid. It is a nitrite's conjugate acid. To treat cyanide poisoning, sodium thiosulfate is combined intravenously with nitrous acid (as sodium nitrite).
