Answer:
B. 0.075 m (NH4)3PO4
Explanation:
Our strategy here is to recall the van´t Hoff factor, i, for the colligative properties of electrolyte solutions which appears as the consequence that electrolytes disociate completely in their solutions in water.
Thus in this problem we need to determine i and then realize the one with the lowest freezing point will have the biggest i ( all the concentrations are equal) since
ΔTf = i m Kf
Substance van´t Hoff factor
Li I 2
(NH4)3PO4 4
NaIO4 2
KCN 2
KNO2 2
The correct answer is B. 0.075 m (NH4)3PO4
The answer is (C) The electrons are moving easily between the nuclei of metal atoms.
The explanation:
-The electrons then move freely throughout the space between the atomic nuclei. ... Metals are good conductors of electricity because the electrons in the electron sea are free to flow and carry electric current. Metals are ductile and malleable because local bonds can be easily broken and reformed.
1-Metals are good conductors of electricity because the electrons in the electron sea are free to flow and carry electric current.
2-Metals are ductile and malleable because local bonds can be easily broken and reformed.
3-Metals are shiny. Light cannot penetrate their surface; the photons simply reflect off the metal surface. However, there is an upper limit to the frequency of light at which the photons are reflected.
Answer:
It converts The liquid into a gas at the same temperature.
Explanation:
Wet chemical system components typically are a storage tank or tanks, piping, nozzles, and an actuating mechanism.
<h3>
Which parts make up an actuation mechanism?</h3>
The typical components of an actuation mechanism include a motor, transmission, control units, feedback, signaling, interlocking, and shutdown units. An electrical, hydraulic, or pneumatic drive is used to move a valve, shutter, or gate, which acts as an actuator to regulate the flow of fluids or gases.
<h3>
What is the operation of the operator-dependent actuating mechanism?</h3>
When an automatic clutch is engaged, the control system 2 replaces the target-value signals coming over feeders 1 with the operator force signal if the operator uses the operator-dependent actuating mechanism.
