Burning and other changes in matter do not destroy matter. The mass of matter is always the same before and after the changes occur. The law of conservation of mass states that matter cannot be created or destroyed

Which statement describes the Arrhenius interpretation of acids and bases?
Alexeev081 [22]

Answer:

D. It is limited to situations that involve aqueous solutions or specific compounds.

Explanation:

An Arrhenius acid is a substance that increases the concentration of H3O or H+ when dissolved in water. An Arrhenius base is a substance that increases the concentration of OH- when dissolved in water. These definitions tell us that D is indeed limited to situations that involve aqueous solutions or specific compounds, as aqueous means something that's dissolved in water.

A is wrong because the Bronsted-Lowry interpretation has a wider range of applications. Bronsted-Lowry acids and bases don't even need to be aqueous, so it is not limited to just aqueous solutions. They include any substance that can donate or accept a H+.

B is wrong because A is wrong. A and B basically say the same thing, that the Arrhenius interpretation has a wider range of applications than the Bronsted-Lowry interpretation.

C is wrong because the definition of an Arrhenius base is any substance that increases the concentration of OH-, or hydroxide ions. C completely counters this statement.

the import of foreign alcoholic beverages is highly taxed with respect to those alcoholic beverages produced within Bhutan.Expla
ASHA 777 [7]

Answer:Putting a full stop on the import of alcoholic beverages is out of question, says the Finance Minister Lyonpo Wangdi Norbu.

The minister was responding to BT’s query about the possibility of a ban on the import of alcoholic beverages in the near future, at the sidelines of the last Meet-The-Press.

The Finance Minister said disallowing alcohol imports would not be a right approach.

He said such issues should be tackled with systematic measures, explaining that levying high import taxes can be reckoned as a pertinent limiting factor.

“Ban on import of foreign drinks is out of question considering the substantial revenue generated by imposing high taxation on these products,” the minister said. Lyonpo said such restriction is not on the cards, at least for quite some time. Similarly, the Labor Minister, Lyonpo Dorji Wangdi said such policies, if at all come to action, would not prove sensible. “People have every right to consume foreign drinks as long as they can afford to pay,” he said, adding the ban should not materialize as a government strategy.

Explanation:“The fees for registering alcohol brands like Red Label whiskey in the country alone works out to be approximately Nu 20,000 in one year. Ultimately the benefit goes to the people,” the minister said. Observers say ban on the import of foreign liquor could prove beneficial at this time given the rupee problem as the import of such commodities has been rising each year. A study carried out by a Task Force to compare contribution of major commodities to total consumption expenditure revealed that alcohol beverages, tobacco and narcotics falls under the top 12 commodity attributors. For example, the report exhibits import of beer as a major import item from India. While Nu 233.06 million was spent in 2009, the import expenditure drastically augmented to Nu 314.75 million in 2010. Some say limiting import of liquor would also help reduce consumption and alcohol related morbidity to certain extent. There are five operational breweries in the country and two more are expected to come up soon. While the annual production of the Army Welfare Project (AWP) in the year 2010 stood at 6.9 million liters, surprisingly, the total consumption of alcohol in the same year was 40.75 million liters. The two AWP distilleries in Gelephu and Samtse.

Identify structure(s) for all constitutional isomers with the molecular formula C4H8 that have one double bond. Select all that
Alchen [17]

Answer:

a) But-1-ene

b) E-But-2-ene

c) Z-But-2-ene

d) 2-Methylpropene

Explanation:

In this case, if we want to draw the <u>isomers</u>, we have to check the<u> formula </u>C_4_H8 in this formula we can start with a linear structure with 4 carbons. We also know that we have a double bond, so we can put this double bond between carbons 1 and 2 and we will obtain <u>But-1-ene.</u>

<u />

For the next isomer, we can move the double bond to carbons 2 and 3. When we do this can have two structures. When the methyl groups are placed on the same side we will obtain <u>Z-But-2-ene</u>. When the methyls groups are placed on opposite sides we will obtain <u>E-But-2-ene.</u>

<u />

Finally, we can use a linear structure of three carbons with a methyl group in the middle with a double bond, and we will obtain <u>2-Methylpropene.</u>

<u />

See figure 1 to further explanations.

I hope it helps!
