Answer:

Some objects of more than 15 cm and less than 30 cm can be:

A rule.

A cell phone.

A pencil.

A calculator.

A laptop charger.

We have to measure it helps us to compare and to obtain physical magnitudes of different objects.

Measurement is the action of obtaining a representative magnitude of a particular object, now, to measure we need to compare and have reference points.

According to valence bond theory, which orbitals overlap in the formation of the bond in HCl?

SIZIF [17.4K]

A) 1s on H and 3p on Cl

In HCl, the H atom has only one valance electron. Each share an electron an therefore a single covalent bond is formed between the two. The bond in HCl is therefore a result of an overlap between 1s orbital and ONLY ONE of the lobes of the 3p orbital of Chlorine.

Consider two gases, A and B, are in a container at room temperature. What effect will the following changes have on the rate of

Oksanka [162]

Answer:

B: increase.

Explanation:

When we are considering two gases A and B in a container at room temperature .

We have to find the change on rate of reaction when the number of molecules of gases A is doubled

Let [A]=a and [B]=b

A+B $\rightarrow$ product

Rate of reaction

$R_1=k[A][B]=kab$

We know that concentration is increases with increase in number of moles

When the number of molecules of gases A is doubled then concentration of gases A increases.

Therefore ,[A]=2a

Rate of reaction

$R_2=k(2a)(b)=2kab$

$R_2=2R_1$

Hence, the rate of reaction is 2 times the initial rate of reaction.Therefore, the rate of reaction will increase when the number of molecules of gases A is doubled.

Answer: B: increase.

elena55 [62]

Answer:

B. Valence Electron Pairs

Explanation:

Valence-shell electron-pair repulsion, or VSEPR, describes the shape of molecules by determining the repulsion of valence electrons. Therefore, our answer is B.
