On the inside of the refrigerator door are NOT required Permanent safety markings

<u>Explanation:</u>

Normally in red color the Permanent safety markings arre done. That are wanted on household refrigerators that accept any refrigerant with an A3 flammability grade such as HCs, on or near any evaporators, any exposed refrigerant tubing, near the machine compartment, and on the exterior of the refrigerator.

Each of these markings shall be in words no short than 6.4 mm (1/4 inch) long. Room residents should remove the place quickly regarding the unexpected release of this refrigerant. "DANGER—Risk of Fire or Explosion. Flammable Refrigerant Used. To Be Repaired Only By Trained Service Personnel. Do Not Puncture Refrigerant Tubing.”  is the quote to be marked in the above specified places.

The elements in Groups 1 and 2 get more reactive as you go down the group.
deff fn [24]

Answer:

Sodium and Magnesium

Explanation:

The elements in Groups 1 and 2 get more reactive as you go down the group.

This means that Sodium is more reactive than lithium and Magnesium is more reactive than beryllium.

On the periodic table, as you go down the group, the reactivity of an element increases. Especially with metals in group 1 and 2. Now Lithium is a metal of group 1, followed by Sodium, while Beryllium is a metal in group 2, followed by magnesium. That's how I picked the answers

A sample of water is heated from 60.0 °C to 75.0°C by the addition of 140 j of
kupik [55]

Mass of the water : 2.23 g

<h3>Furter explanation</h3>

Heat

Q = m.c.Δt

m= mass, g

c = heat capacity, for water : 4.18 J/g° C.

ΔT = temperature

Q= 140 J

Δt = 75 - 60 = 15

mass of the water :

\tt m=\dfrac{Q}{c.\Delta T}=\dfrac{140}{4.18\times 15}=2.23~g

Consider the following three-step mechanism for a reaction: Cl2(g)⇌2Cl(g)Fast Cl(g)+CHCl3(g)→HCl(g)+CCl3(g)Slow Cl(g)+CCl3(g)→CC
kupik [55]
Following steps are involved in the reaction

Step 1:  <span>Cl2(g)⇌2Cl(g)

Step 2: </span><span>Cl(g)+CHCl3(g)→HCl(g)+CCl3(g)

Step 3: </span><span>Cl(g)+CCl3(g)→CCl4(g)
......................................................................................................
Overall reaction : </span>Cl2(g) + CHCl3(g) → HCl(g) + CCl4(g)

Note: Overall reaction is obtained by adding step 1-3 and canceling common terms that are present on reactant and product sides.
