Why acidic character of oxides of group 15 elements decreases down the group?
The ability of the hydride to donate a hydrogen ion can be directly correlated with the decreasing bond strength of the element-hydrogen bond. That is, as the bond strength decreases down the family, the acidity increases. For the same reason, the general chemical reactivity of nonmetal hydrides also increases with increasing atomic number of the nonmetal.
Why does Lewis acid strength of boron trihalides decreases down the group in periodic table?
fiBACK BONDING is effective
What metallic element is added to steel to make it stronger?
Steel is an alloy, and it is made from the elements ironand carbon. Other elements and combinations of elements can be added to the steel to change its properties to fit different applications, including :Chromium - improves durability and prevents rust (stainless steel).Nickel - increases durability and resistance to heat and acids.Manganese - increases strength and resistance to wear.Molybdenum - increases strength and resistance to heat.Tungsten - retains hardness at high temperatures.Vanadium - increases strength and springiness.
How can the strength of metallic bonding be measured?
The amount of heat energy required to vaporize a metal is a measure of the strength of metallic bonding.
What is the relationship between metallic bond strength and enthalpy of vaporization?
Metallic bond strength refers to the amount of energy as heat required to vaporize the metal. The enthalpy of vaporization is defined as the amount of energy absorbed as heat when a specified amount of substance vaporizes at constant pressure. Metallic bond strength increases as the enthalpy increases.

When the distance from a charged particle decreases the strength of the electric field does what?
As the distance from a charged particle increases the strength of its electric field DECREASES.
How would the strength of a bone be affected if the ratio of collagen to calcium increased?
strength decreases flexibility increases
Does heat reduce the tensile strength of metal?
Heating a metal decreases the tensile strength and increases ductility
How does the temperature affect the magnet?
As the temperature increases the strength decreases, and vice versa
Does deformation by drawing decreases the tensile modulus?
deformation by drawing increases tensile strength

How do you apply inverse variation to problems?
If one value of a variable increases as another value of a different variable decreases in a mathematical equation, they are said to be inversely proportional or vary inversely. For example, the strength of the force of gravity decreases as the square of the interacting distance increases, so the strength of gravity is inversely proportional to the square of the distance, or strength ∝ 1/distance2.
Both electric fields and forces decrease in strength as the distance increases?
No. The electric force in this case decreases.
What effect has the quantity of mixing water have upon the quality of concrete?
the strength of concrete is effected by water /cement ratio as the water/cement ratio increases the strength of the concrete decreases
How does distance affect the strength of the force gravity?
Force is inversely related to the square of the distance. Hence as the distance increases the force decreases.
True or False muscular endurance decreases muscular strength bone density muscle size and muscle density?
False it increases them!!!!
