What is the mass in grams of 0.00125 mole of sodium Na=23​

Chemistry
1 answer:
Anit [1.1K]3 years ago
7 0

Answer:

0.03g

Explanation:

Given parameters:

Number of moles of Na = 0.00125mole

Unknown:

Mass in grams of Na = ?

Solution:

To find the mass of this substance, we simply multiply the number of moles with the given molar mass of Na.

 Mass of Na  = number of moles x molar mass

 Mass of Na  = 0.00125 x 23   = 0.03g

What is the empirical formula for the compound: C8H8S2?
almond37 [142]

Answer:

<h2><em><u>Empirical formula = C4H4S</u></em></h2>

Explanation:

The subscripts in a formula determine the ratio of the moles of each element in the compound. To convert this formula to the empirical formula, divide each subscript by 2. This is similar to reducing a fraction to its lowest denominator.

How many grams of gasoline would you need to burn to move your car 2.5 miles which takes 5,375 kJ? (Hrxn= 47kJ/g)
docker41 [41]

Answer:

1.1 × 10² g

Explanation:

The combustion of gasoline releases energy that is used to move the car. The enthalpy of reaction (ΔH°rxn) of the combustion of gasoline is 47 kJ/g, that is, 47 kiloJoule are produced per gram of gasoline burned. The mass of gasoline to be burned to release 5,375 kJ is:

5,375 kJ × 1 g Gasoline/47 kJ = 1.1 × 10² g

What chemicals do i need to make methanph<br>etamine​
rusak2 [61]

Answer:

Currently, most methamphetamine in the United States is produced by transnational criminal organizations (TCOs) in Mexico.44 This methamphetamine is highly pure, potent, and low in price. The drug can be easily made in small clandestine laboratories, with relatively inexpensive over-the-counter ingredients such as pseudoephedrine, a common ingredient in cold medications.

To curb production of methamphetamine, Congress passed the Combat Methamphetamine Epidemic Act in 2005, which requires that pharmacies and other retail stores keep logs of purchases of products containing pseudoephedrine and limits the amount of those products an individual can purchase per day. Restrictions on the chemicals used to make methamphetamine in the United States have dramatically reduced domestic production of the drug. In 2010, there were 15,256 domestic methamphetamine laboratory incidents—a figure that has fallen over 80 percent to 3,036 in 2017.44 Data on drug seizures indicate that most domestic production of methamphetamine is now conducted in small laboratories that make two ounces or less of the drug using common household items.44

Mexico has also tightened its restrictions on pseudoephedrine and other methamphetamine precursor chemicals. But manufacturers adapt to these restrictions via small- or large-scale "smurfing" operations: obtaining pseudoephedrine from multiple sources, below the legal thresholds, using multiple false identifications. Manufacturers in Mexico are also increasingly using a different production process (called P2P which stands for pseudoephedrine’s precursor chemical, phenyl-2-propanone) to make methamphetamine that does not require pseudoephedrine.

When methamphetamine is smuggled into the United States in powder or liquid form, domestic conversion laboratories transform it into crystal methamphetamine. These laboratories do not require a significant amount of equipment, so they can be small in size and thus easily concealed, which presents challenges to law enforcement agencies.44 Methamphetamine pressed into a pill form intended to resemble ecstasy has also recently emerged, potentially in an effort to make methamphetamine more appealing to people who haven’t tried it before.44 As with other illicit drugs like heroin and cocaine, methamphetamine is also sometimes laced with fentanyl.44

Methamphetamine production is also an environmental concern; it involves many easily obtained chemicals that are hazardous, such as acetone, anhydrous ammonia (fertilizer), ether, red phosphorus, and lithium. Toxicity from these chemicals can remain in the environment around a methamphetamine production lab long after the lab has been shut down, causing a wide range of damaging effects to health. Because of these dangers, the U.S. Environmental Protection Agency has provided guidance on cleanup and remediation of methamphetamine labs.
