The correct answer of the given question above would be a PICTOGRAM. OSHA’s required pictograms must be in the shape of a square set at a point and
include a black hazard symbol on a white background with a red frame sufficiently wide enough to
be clearly visible.
|F| = 112 - 67 = 45 N
F = 45 N ( to the left)
the balanced chemical equation representing the reaction between represent sodium metal (Na) and chlorine gas (cl2) is as below
2 Na + Cl2→ 2 NaCl
2 moles of sodium metal ( Na) reacted with 1 mole of gas chlorine gas (cl2) and 2 moles of sodium chloride (NaCl)
Answer:
When the volume increased from 2.00 to 5.25L the new temperature is 808.9 K ( =535.75 °C)
Explanation:
Step 1: Data given
The initial volume of the sample = 2.00 L
The initial temperature = 35 °C = 308 K
The increased volume = 5.25 L
Pressure = constant
Step 2: Calculate the new temperature
V1/T1 = V2/T2
⇒ with V1 = the initial volume = 2.00 L
⇒ with T1 = the initial volume = 308 K
⇒ with V2 = the new volume = 5.25 L
⇒ with T2 = the new temperature
2.00 / 308 = 5.25 / T2
0.00649 = 5.25/T2
T2 = 5.25/ 0.00649
T2 = 808.9 K
When the volume increased from 2.00 to 5.25L the new temperature is 808.9 K ( =535.75 °C)
