NaHS is an acidic salt.
NaHS is obtained by replacement of one acidic hydrogen of `H2S` by Na (on reaction with NaOH).
<h3>What do we know about NaHS?</h3>
The chemical compound with the formula NaSH is sodium hydrosulfide. This substance is created when hydrogen sulfide is partially neutralized with sodium hydroxide. In the industrial setting, sodium sulfide and NaSH are frequently employed for the same things. Solid NaSH has no color.
Solution of sodium hydrosulfide is a colorless to light-yellow liquid. corrosive to flesh and metals. It is employed in the production of colors and paper pulp.

B) Tellurium is a metalloid. Metalloids in some classifications are also or alternatively called “semi-metals.”
Answer:
Gas
Explanation:
This is kind of like the process of evaporating
Answer:
31.9 °C
Explanation:
The formula for the heat q absorbed by an object is
q = mCΔT where ΔT = (T₂ - T₁)
Data:
q = 12.35 cal
m = 19.75 g
C = 0.125 cal°C⁻¹g⁻¹
T₂ = 37.0 °C
Calculations
(a) Calculate ΔT
q = mCΔT
12.35 cal = 19.25 g × 0.125 cal°C⁻¹g⁻¹ × ΔT
12.35 = 2.406ΔT °C⁻¹
ΔT = 12.35/(2.406 °C⁻¹) = 5.13 °C
(b) Calculate T₂
ΔT = T₂ - T₁
T₁ = T₂ - ΔT = 37.0 °C - 5.13 °C = 31.9 °C
The original temperature was 31.9 °C.
