If an acid/base dissociates completely in water what type of substance is it? Does this mean the acid/base is dangerous?

Chemistry
1 answer:
hram777 [196]3 years ago
3 0

Answer:

1 strong acid

2 yes they are dangerous

Explanation:

Since nearly all of it is dissociated in water, it is called a strong acid.

2 yes Concentrated strong acids can cause severe and painful burns. The pain is due in part to the formation of a protein layer, which resists further penetration of the acid

What is amu of 99 % H-1, .2% H-1 and .8% H-3
ankoles [38]

The average atomic mass of your mixture is 1.03 u .

The average atomic mass of H is the weighted average of the atomic masses of its isotopes.  

We multiply the atomic mass of each isotope by a number representing its relative importance (i.e., its % abundance).  

Thus,  

0.99    × 1.01 u = 0.998 u

0.002 × 2.01 u = 0.004 u

0.008 × 3.02 u = <u>0.024 u</u>

            TOTAL =  1.03   u

Which property of a liquid increases with increasing temperature?
Nina [5.8K]
When temperature of liquid is increased, liquid gets thinner and thinner and hence it's viscosity decreases.

Density = mass/volume.

As we increase the temperature, volume of the liquid starts to increase but mass of the liquid remains constant. As a result, density of liquid decreases.

Hope this helps!

What sort of evidence would support at least one of the components of the
Yuki888 [10]

Answer:

(not sure) The origin of all cells observed can be traced to previous cells

Explanation:

- not all cells convert energy (?) (this I'm not sure but think so? might be wrong tho)

- not all cells have cell walls e.g. animal cells only have the cell membrane, no cell wall

- Rocks and other nonliving things are composed of cells: non living things are composed of the elements and not cells (unless they were previously alive, then they contain dead cells)

A sky rocket is launched with a force of 10 N and accelerates at 20 m/s squared what is the mass of this skyrocket
tia_tia [17]

Answer: 0.5 kg

Explanation:

Force of launched skyrocket = 10 N

Acceleration of skyrocket = 20 m/s squared (i.e 20m/s^2)

Mass of the skyrocket = ?

Recall that Force is the product of the mass of an object by the acceleration by which it moves.

i.e Force = Mass x Acceleration

10N = Mass x 20m/s^2

Mass = (10N/20m/s^2)

Mass = 0.5 kg

Thus, the mass of this skyrocket is 0.5 kilograms
