Element is represented by symbol since about 118 elements are known to us.

Some elements takes its first letter as its symbol for example  

Hydrogen      H

Oxygen         O

Nitrogen        N

Phosphorus   P

Sulfur              S

Fluorine          F

Some elements takes the first and the second letter as its symbol for example  

Calcium       Ca

Beryllium     Be

Lithium         Li

Argon           Ar

Radium        Ra

Bromine       Br

Cobalt          Co

Nickel           Ni

Some element have the first letter and one of the letter from the name of the element for example

Chlorine          Cl

Zinc                 Zn

Magnesium     Mg

Manganese     Mn

3690 J of heat are added to a 21.5 g sample
Fiesta28 [93]

Answer:

693K

Explanation:

The enthalpy change in the iron is 3690J

We now apply the formula for enthalpy change which is ΔH=mC∅ where ∅ is the temperature change, m the mass of the substance, and C the specific heat capacity for the substance.

ΔH in this case is 3690J.

Therefore 3690J=21.5g×0.449J/g.K×∅

as we are looking for ∅, we make it the subject of the formula.

∅=3690J/(21.5g×0.44J/g)

∅=390

Temperature=30°C +390

=420°+273

=693K

Hydrologers study the availability of fresh water on the planet.
Dahasolnce [82]

Answer:

Hydrologists study how water interacts with the earth's crust. For example, they may study how rainfall and snowfall cause erosion, create caves, percolate through soil and rock to become groundwater, or eventually reach the sea.Hydrologists strive to improve water quality and increase our access to water so that we can continue to make use of it in all the ways that are necessary to our lives. A hydrologist measures the stream flow in a tributary to the Coeur d'Alene River. layers of gases surrounding a planet or other celestial body

What is the maximum vertical distance between the line y = x 2 and the parabola y = x2 for −1 ≤ x ≤ 2?
Mrac [35]

x2=x+2 at x=−1 and x=2 so we have no need to worry about the end-points

f(x)=x+2−x^2

df/dx=1–2x

and that is zero (indicating a maximum) at x=1/2

So the maximum distance is f(1/2)=2.5–0.25=2.25

Lena [83]

Answer:

Na₂O will also form a brittle ionic compound.

Explanation:

Sodium is located in the same group as Potassium: Alkali Metals. This is because both elements have similar chemical properties. In term of their electronegativity, both elements are very close. Na has an electronegativity of 0.93, while K has an electronegativity of 0.82. This makes both ideal elements to create ionic compounds with Oxygen.
