Answer: Option (b) is the correct answer.

Explanation:

When we increase the temperature of an object then there will be increase in kinetic energy of objects. As a result, collision between the molecules will increase.

Hence, there will be increase in rate of reaction.

Also, K.E = $\frac{3}{2}kT$

where k = boltzmann constant

T = temperature

So, kinetic energy is proportional to temperature. Hence, when temperature will increase the kinetic energy will also increase.

Thus, we can conclude that an increase in temperature generally affect the rate of a reaction as the rate increases.

Which substance is a binary acid

elena-s [515]

<span>It is known that acids compounds contains hydrogen and produces hydrogen ion in water. A binary acid however is an acid that have two elements, one of the element has a hydrogen attached to it. Examples of binary acids are hydrogen fluoride (HF), hydrogen bromide (HBr) and hydrogen sulfide (H2S). In naming a binary acid, it has two rules; one, as pure compounds and two, as acid solutions. For pure compounds, start with the name ‘hydrogen’ and end the anion name with ‘-ide’. For acidic compounds, start with ‘hydro-‘, end the anion with ‘-ic’ and add ‘acid’.</span>

what is the difference between the number of electrons in an atom of selenium, Se and the number of electrons in an atom of alum

ELEN [110]

Answer:

Well, electrons can be converted into a atomic number so if SE atomic number is 34 that means it has 34 electrons. AI has a atomic number of 13 meaning it has 13 electrons. So the difference is that SE has more electrons then AI.

1. _ LiBr2 + __K2CO3 -->___ LiCO3 +_ KBr<br> Reaction Type:

Arada [10]

Answer:

Double displacement chemical reaction.

Explanation:

Hello,

In this case, for the given reaction we firstly balance it:

$LiBr_2 +K_2CO3 \rightarrow LiCO3 +2KBr$

Then, since the lithium and potassium cations are being exchanged to each other from bromide and carbonate, we are talking about a double displacement chemical reaction.

Best regards.

21 pts. Sodium reacts with oxygen to produce sodium oxide as described by the balanced equation below. If 54.1g of sodium reacts

Aleksandr [31]

First, calculate the amount fo Na2O that should be produced with the given amount of sodium using proper dimensional analysis and the balanced chemical reaction,

theoretical amount of Na2O = (54.1 g of Na)(1 mol Na/23 g Na)(2 mos Na2O/4 mols Na)(62 g Na2O/ 1mol Na2O)

theoretical amount of Na2O = 72.9 g of Na2O

Calculation of percent yield,

% yield = (61.8 g Na2O) / (72.9 g of Na2O) x 100%
% yield = 84.75%

Answer: 84.75%
