Answer:
87 (whatever unit its using)
Sanitized indirectly vented chemical splash goggles or safety glasses as appropriate
(meeting the ANSI Z87.1 standard) shall be worn during activities or demonstrations
in the classroom, laboratory, or field, including pre-laboratory work and clean-up,
unless the instructor specifically states that the activity or demonstration does not
require the use of eye protection.
The correct answer would be the third option. The chemical properties cycle through each period because the atoms' outermost shells having two or more electron shells cannot have more than eight electrons. This is following the octet rule.
Answer:
V of Sulfur tetrafluoride is 17.2 L
Explanation:
Given data;
T = -6°C = 267K [1° C = 273 K]
n = 786 mmol of SF4 which is 0.786 mol
P = 1 atm
from ideal gas law we have
PV = nRT
where n is mole, R is gas constant, V is volume
V of Sulfur tetrafluoride is 17.2 L
