Is bro2 polar or nonpolar

1 answer:

5 0

Bro2 is polar because the rules for overall polarity of Neutral Species Arrangement of Group Linear Trigonal Planar Tetrahedral Trigonal Bipyramidal Octahedral Polarity if atoms on either side of the center atom are different, the species is polar if any group around the central atom is different.

During an exothermic chemical reaction, a solid is consumed and a gas produced. a. Yes b. No c. Can't decide with information gi

kiruha [24]

<u>Answer:</u> The given statement is true.

<u>Explanation:</u>

For the reaction to be spontaneous, the Gibbs free energy of the reaction must come out to be negative.

The equation used to calculate Gibbs free energy follows:

$\Delta G=\Delta H-T\Delta S$

Exothermic reactions are defined as the reactions in which energy is released in the form of heat. The enthalpy change $(\Delta H)$ of the reaction comes out to be negative for this kind of reaction.

Entropy change is defined as the change in the measure of randomness in the reaction. It is represented as $(\Delta S)$ . Randomness of gaseous particles is more than that of liquid which is further more than that of solids.

We are given:

A solid substance is converting into a gaseous substance.

$\text{Solid}\rightarrow \text{Gas}$

As, the entropy is increasing. So, the entropy change is positive.

Thus, the above reaction is spontaneous. $\Delta G=-ve-(+ve)\\\\\Delta G=-ve$

Hence, the given statement is true.

How do you Convert 62 grams of Oxygen to moles

ioda

Answer: 1.9 moles

Explanation:

Step 1: Determine how many grams of a substance are in the problem.

From the question; we have 62 grams of Oxygen

Step 2: With the aid of a periodic table, the atomic mass of Oxygen is 16g, but since oxygen is diatomic i.e O2, it's molecular mass would be 32g.

Step 3: Applying the mathematical expression for finding moles

Moles = Mass/ Molar Mass

= 62g/ 32 g

= 1.9

∴ 62g of oxygen is equivalent to 1.9 moles.

You wish to make 250. mL of 0.20 M KCl from a stock solution of 1.5 M KCl and DI water.

Nitella [24]

The question requires us to use the dilution formula $M_iV_i=M_fV_f$ , where $M_i$ and $V_i$ are the stock concentration and volume respectively, then $M_f$ and $V_f$ are the dilute concentration and volume respectively.

a. $C_s_t_o_c_k$ = 1.5 M KCI, $C_d_i_l_u_t_e$ =0.20M KCl, $V_d_i_l_u_t_e$ =250ml KCl

b. $M_iV_i=M_fV_f\\\implies V_i= \frac{M_fV_f}{M_i} = \frac{0.20M \times 250ml}{1.5M} = 33.3\ ml$

To prepare the solution 33.3ml of 1.5M KCl is diluted to a total final volume of 250ml.

What happens during ice wedging

jek_recluse [69]

Frost wedging happens when water gets in crack, freezes, and expands. This process breaks rocks apart. When this process is repeated, cracks in rocks get bigger and bigger and may fracture, or break, the rock.

Hope this helps :)
