Answer:

Sodium hydroxide is a strong base. In concentrated form its pH can go up to somewhere in the region of 13-14. On contact with the skin in this form, it will leave severe burns and severe tissue damage. All bases have OH- ions while acids have H+ ions.

What is the specific heat capacity of a 250g object that needs 34.125kJ to have its own temperature raised by 65.0∘C

Anestetic [448]

Answer:

Specific heat capacity, = 2.1J/g°C

Explanation:

Given the following data;

Mass = 250g

Quantity of heat = 34.125kJ = 34.125 * 1000 = 34125 Joules.

Change in temperature = 65.0∘C

To find the specific heat capacity;

Heat capacity is given by the formula;

$Q = mcdt$

Where;

Q represents the heat capacity or quantity of heat.

m represents the mass of an object.

c represents the specific heat capacity of water.

dt represents the change in temperature.

Making c the subject of formula, we have;

$c = \frac {Q}{mdt}$

Substituting into the equation, we have;

$c = \frac {34125}{250*65}$

$c = \frac {34125}{16250}$

Specific heat capacity, = 2.1J/g°C

In static equilibrium, the potential difference between two points inside a solid piece of metal Group of answer choices is zero

levacccp [35]

Answer:

it is zero because the electric gap is zero within the material

Explanation:

In a metal you have many free electrons, and fixed charges formed by nuclei and electrons that are not free; therefore the charge carriers are the free electrons, these have the same negative charge and due to the lectrostatic force they repel each other as far as possible without leaving the material, this implies that at two points there must be the same potential because otherwise there would be a net Caesarian force accumulating charge in a part that would be eliminated by the Coulomb force.

With this we can review the statements the strap is: it is zero because the electric gap is zero within the material

Are there any difference betwn supersonic planes and concorde planes

malfutka [58]

<u>Answer</u>:

Yes, there are differences between supersonic planes and concorde planes

<u>Explanation</u>:

The supersonic planes moves faster than the speed of sound. But these flights are banned because it is economically non-starter. It has more loud sound equivalent to the explosion. The banned was elevated in 2003, due to new aviation law. The concords travel twice the speed of sound. This planes holds the record for the fastest planes but seen to be fleet long back i.e. in 2003. These were banned when a fatal crash had been reported. And now are only found in the museums.
