Answer:
Its 19.
Explanation:
K (potassium) has 19 electron according to the atomic number in the periodic table. The atomic number tells you the number of protons and electrons.
Answer:
Distance cover = 8 km
Explanation:
Given:
Speed of runner = 4 km/h
Time taken = 2 hour
Find:
Distance cover
Computation:
Distance = Speed x Time
Distance cover = Speed of runner x Time taken
Distance cover = 4 x 2
Distance cover = 8 km
Answer & explanation:
Canned fruits and vegetables generally have a high acidity and salinity content, in order to prevent the product from spoiling, in addition to enhancing its flavor.
The cream-based sauce started to curdle due to the acidity present in the canned tomatoes.
By lowering the pH of dairy products, a protein in them called casein begins to clot. It is this clotting of the casein that causes the cream-based sauce to curdle.
<u>Ans: (2) The gas particles have no attractive forces between them.</u>
The kinetic theory explains the behaviour of a hypothetical ideal gas. It explains pressure in terms of the collision of gas particles against the walls of the container which it occupies.
The kinetic theory of gases is based on three main postulates:
1) The collision between gas particles is elastic i.e. no energy is lost or gained
2) The gas particles are treated as point masses i.e. the volume occupied by the gas particles is negligible when compared to the volume of the container
3) There are no attractive or repulsive forces between particles.
Answer:52M
Explanation:
use S= 1000w/ MV
Here, s= molarity
w= the amount of NaCl
M= the atomic mass of NaCl
V= the volume of solution
