Answer:

The correct answer is option b. Hypothesis.

Explanation:

The hypothesis is an idea or a guess that is formulated on the observation of a problem or natural phenomenon which is based on prior knowledge or research.

The hypothesis is not a random guess and it is also not a well-sustained explanation, it lies in between. The hypothesis is generally formed to prove or test if it is true or not.

Thus, the correct answer is option - b. Hypothesis.

When 16.4 g of steam at 100°C condenses how much heat is released?
OLEGan [10]

Answer:

37064 J

Explanation:

Data Given:

mass of Steam (m) = 16.4 g

heat released (Q) = ?

Solution:

This question is related to the latent heat of condensation.

Latent heat of condensation is the amount of heat released when water vapors condenses to liquid.

Formula used

            Q = m x Lc . . . . . (1)

where

Lc = specific latent heat of condensation

Latent heat of  vaporization of water is exactly equal to heat of condensation with - charge

So, Latent heat of  vaporization of water have a constant value

Latent heat of  vaporization of water = 2260 J/g

So

Latent heat of condensation of water will be = - 2260 J/g

Put values in eq. 1

          Q = (16.4 g) x (- 2260 J/g)

          Q = - 37064 J

So,  37064 J of heat will be released negative sign indicate release of energy

Classify the following reaction *
hichkok12 [17]

Answer:

double replacement

Explanation:

The reaction equation is given as:

       Pb(NO₃)₂  +  2KI   →   PbI₂ +   KNO₃

This reaction is a double displacement reaction.

In this form of reaction, there is an actual exchange of partners to form new compounds.

      AB + CD →  AD + CD

One of the following condition serves as driving force for the reaction:

  • formation of an insoluble compound
  • formation of water or any other non-ionizing compound
  • liberation of a gaseous product.
