nikklg [1K]

Answer:

c) non polar Covalent

Explanation:

this is a molecule formed by atoms of the same element . they both have similar electronegativities and thus cancel out . This makes it a perfect Covalent molecule . The fact that it's a symmetrical molecule makes it non polar. a symmetrical molecule is a molecule formed by the overlap of orbitals of two atoms of the same element ( that is to say , there's no dipole )

How much water would I need to add to 700 mL of a 2.7 M KCl solution to make a 1.0 M solution?
geniusboy [140]

Answer:

1190\ \text{mL}

Explanation:

M_1 = Initial Concentration of KCl = 2.7 M

V_1 = Volume of KCl = 1 M

M_2 = Final concentration of KCl = 1 M

V_2 = Amount of water

We have the relation

M_1V_1=M_2V_2\\\Rightarrow V_2=\dfrac{M_1V_1}{M_2}\\\Rightarrow V_2=\dfrac{2.7\times 700}{1}\\\Rightarrow V_2=1890\ \text{mL}

The amount of water that is to be added is 1890-700=1190\ \text{mL}.

Which type of property can be observed only by changing a substance into a different substance
Nana76 [90]

Chemical Property

<u>Explanation:</u>

When a substance is changed into another substance, may be due to addition of some other substance or removal of water from that substance.

* its identity changes

*its reactivity changes

*reactivity towards water, air and many other substances will change

*its chemical composition changes

and all these changes occurs due to the chemical properties.

If the physical property changes then there will be change in the state of matter, but its boiling point, melting point , reactivity towards water, air and other substances will not change, and it will not lose its identity.
