What is radioactive decay?

Chemistry
1 answer:
swat322 years ago
7 0

Answer:

Radioactive decay is the process by which an unstable atomic nucleus loses energy by radiation. A material containing unstable nuclei is considered radioactive. Three of the most common types of decay are alpha decay, beta decay, and gamma decay, all of which involve emitting one or more particles or photons.

Wht are the trends for electronegativity and ionzation energy similar​
FinnZ [79.3K]

Answer:

Along period electronegativity and ionization energy increases.

Along group electronegativity and ionization energy decreases.

Explanation:

Along period:

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. Thus the attraction of the atoms for valance electrons increases. 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 and ionization energy increases because it is very difficult to remove the electron from atom and more energy is required, and electronegativity also increases.

Along group:

As we move from top to bottom in periodic table the atomic sizes increases.The electrons are added in next energy level in every next element. Thus the valance electrons farther away from the nucleus and hold of nucleus becomes weaker,  because of weak nuclear attraction atomic radii increases and electronegativity and ionization energy decreases.

Match the distance/time graphs to the motion description.
Neporo4naja [7]
Graph A represents constant speed so the answer for this is the car is moving at constant speed. Time is increasing to the right, whereas distance is increasing constantly with time. 
Graph B represents the car is coming back because from the starting point it is decreasing because while velocity is +, the magnitude keeps on lowering.
Graph C represents the car is stopped since it time increasing to the right but there is no change in speed.
Graph D represents the speed of the car is decreasing because distance in each time interval is decreasing.

For each of the following unbalanced equations, calculate how many grams of each product would be produced by complete reaction
ycow [4]

Answer:

10.6g of SO_{2}

2.0g of H_{2}O

Explanation:

First we are going to balance the reaction:

S+_{2}H_{2}SO{4}=_{3}SO_{2}+_{2}H_{2}O

Then we are going to find the quantities with the stoichiometry:

-For SO_{2}:

10.8gH_{2}SO_{4}*\frac{1molH_{2}SO_{4}}{98.079gH_{2}SO_{4}}*\frac{3molesSO_{2}}{2molesH_{2}SO_{4}}*\frac{64.066gSO_{2}}{1molSO_{2}}=10.6gSO_{2}

-For H_{2}O:

10.8gH_{2}SO_{4}*\frac{1molH_{2}SO_{4}}{98.079gH_{2}SO_{4}}*\frac{2molesH_{2}O}{2molesH_{2}H_{2}O}*\frac{18.015gH_{2}O}{1molH_{2}O}=10.6gH_{2}O=2.0gH_{2}O
