You could say that you played outside so you or your dog didn't hit anything important/fragile.

You could say that you played with his/her favourite soft toys, so that you didn't hurt anyone or again break anything.

You can say that you did your tests in a safe place where no one could get hurt.

Hopefully this helps, let me know if you need more answers.

What is the ranking order of the degree of polarity? Of HF,HCI,HBr and HI

Savatey [412]

Answer:

The ranking order of the degree of polarity is HF>HCl>HBr>HI

Explanation:

The degree of polarity of a compound depends on the nature electronegative atom that it contains.

Among Fluorine,chlorine,bromine and iodine the electronegativity of fluorine is highest among all the mentioned atoms.

Due to high electronegativity HF is the most polar than HCl,HBr and HI and the HI have least polarity as its atomic structure is large and electronegativity is lower than fluorine,chlorine and bromine.

This equation represents a:

Leto [7]

Answer : The correct option is, (D) double replacement reaction

Explanation :

Synthesis reaction : A chemical reaction where multiple substances or reactants combine to form a single product.

It is represented as,

$X+Y\rightarrow XY$

Decomposition reaction : A chemical reaction in which larger reactant decomposes to give two or more than two products.

It is represented as,

$AB\rightarrow A+B$

Single replacement reaction : A chemical reaction in which the more reactive element replace the less reactive element.

It is represented as,

$A+BC\rightarrow AC+B$

In this reaction, A is more reactive element and B is less reactive element.

Double replacement reaction : It is a type of chemical reaction where a positive cation and a negative anion of two reactants exchange places to form two new products.

It is represented as,

$XY+AB\rightarrow XB+AY$

(X and A are the cations, Y and B are the anions)

The given reaction is:

$2NaCl(aq)+CuSO_4(aq)\rightarrow Na_2SO_4(aq)_CuCl_2(aq)$

This reaction is a double displacement reaction.
