Answer:
is a chemical bond i think is true
Answer: 3.05L= V2
Explanation:
using
P1V1/T1=P2V2/T2
where p1= 345torr
T1, tempertaure= -15c+ 273=258K
T2, temperature= 36+ 273=309K
p2, Pressure= 468 torr
V2=???
P1V1/T1=P2V2/T2
v2=P1V1T2/T1P2= 345X3.46L X 309/ 258X 468=
V2= 3.05L
Answer:
D.All chemicals are potentially dangerous
Explanation:
No chemical is toxicologically neutral
Answer:
ΔH(mix'g)= 42.3Kj/mole
Explanation:
ΔH = (mcΔT)water/moles X
m = mass(g) = 20ml x 1.00g/ml = 20 g
c = 4.184 j/g⁰C
ΔT = 25°C- 15°C = 10°C
moles X = (1.5g)/(76g/mole) = 0.0197 mole X
ΔH = (20g)(4.184j/g°C)(10°C)/(0.0197 mole X) = 42,300J/mole = 42.3Kj/mole (3 sig.figs.)
Answer:
<em><u>The compound hydrogen chloride has the chemical formula HCl and as such is a hydrogen halide. At room temperature, it is a colourless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric water vapor. Hydrogen chloride gas and hydrochloric acid are important in technology and industry. Hydrochloric acid, the aqueous solution of hydrogen chloride, is also commonly given the formula HCl.</u></em>
