1.Strong basses dissociates into ions almost 100%.

But weak basses partially dissociates into ions.

2.Strong basses has pH value smaller but closer to 14 and weak basses has pH value greater but cloaer to 7.

3.strong basses ate highly reactive whereas weak basses are less reactive.

What is the general trend for valence electrons as you go across the periodic table left to right

Margarita [4]

The atomic radius decreases across a period from left to right and increases down a given group. The atoms with the largest atomic radii are located in group l and at the bottom of groups. Moving from left to right across a period, electrons are added one at a time to the outer energy shell. Hope this helps!

A nitrox ii gas mixture for scuba diving contains oxygen gas at 53 atm and nitrogen gas at 94 atm . what is the total pressure,

Alina [70]

Answer: The total pressure will be 1,11,720 torr.

Explanation:

Partial pressure of nitrogen gas. $p_{N_2}=53 atm=53\times 760 torr= 40,280 torr$ (1atm = 760 torr)

Partial pressure of oxygen gas, $p_{O_2}=94 atm=94\times 760 torr=71,440 torr$

Total pressure, in torrs, of the scuba gas mixture = 40280 + 71440 torr =111,720 torr

Hence , the total pressure in scuba gas mixture is 111,720 torr.

A serving of Frosted Flakes cereal contains 235,000 J of energy. Calculate the change in temperature (ΔT) that would occur if th

timama [110]

The change in temperature (ΔT) : 56.14 ° C

<h3>Further explanation</h3>

Given

Cereal energy = 235,000 J

mass of water = 1000 g

Required

the change in temperature (ΔT)

Solution

Heat can be formulated :

Q = m . c . ΔT

c = specific heat for water = 4.186 J / gram ° C

235000 = 1000 . 4.186 . ΔT

$\tt \Delta T=\dfrac{235000}{1000\times 4.186}=56.14^oC$
