Answer:
H2SO4 + 2NaOH ----> Na2SO4 + 2H2O
Explanation:
This is balanced equation
In a closed container the three states of matter would be solid, liquid and gas
Solid- The solid exists as a rigid solid and has fixed shape and volume. Strong inter molecular and intramuscular forces inhibit the solid from losing its shape and occupying the volume of container.
Liquid- It takes the shape of the container but not the volume of the container. This means the kinetic energy is not large enough for the liquid to cover all the space inside the container.
Gas- The gas expands to take both the shape and volume of the container. This would explain why a balloon inflates when you blow air into it.
Answer:
Cl
Explanation:
Cl have smallest atomic radius because,
As we move from left to right across the periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases. In given list of elements all are present in period three. Chlorine is present at the most right side of periodic table so it has smaller radius and Al in on left side it has greater radius as compared to the elements given in question.
The Kinetic Molecular Theory focuses on the average kinetic energy of the molecules with respect to temperature. As the absolute temperature increases, the kinetic energy also increases. Same is true for the opposite situation. The kinetic energy is manifested by rapid collisions. Thus, the answers are A, C and D.
Answer:
Elements in the same row as one other are known as periods and they share the same highest unexcited electron energy level. ... The table tells each element's atomic number and usually its atomic weight. The typical charge of an element is indicated by its group
