Answer:

Explanation:

Alkaline are great for long-term use in a device, such as in a digital camera or game console remote. Carbon zinc batteries are ideal in a situation where one needs to power multiple devices for one occasion, such as when buying many toys during the Christmas season to be used for a few days.

Answer:

    The main difference between a zinc-carbon and alkaline batteries is the type of electrolyte. zinc-carbon batteries use ammonium chloride while alkaline batteries use potassium hydroxide. the components of each have different applications and better uses depending on the components. The benefits of Alkaline batteries include longer shelf life, and a higher energy density. These batteries will not lose energy from being unused for periods at a time. Panasonic alkaline batteries also have anti-leak protection so they are useful for items like toothbrushes, toys, and some game controllers. zinc batteries are useful for long periods of usage. They are used worldwide because they are affordable and have a low energy consumption. These are useful for fire alarms, smoke detectors, and televisions. Lastly, lithium ion batteries are some of the most frequently used batteries. they are used in devices like smartphones, earbuds/headphones, and cordless tools/appliances. lithium ion batteries are made of lightweight lithium and carbon. Lithium is a highly reactive element which means lots of energy can be stored in it's atomic bonds.  

Explanation: all spell checked and credible sources, just make sure to change some wording so that the essays are not identical :) good luck y'all

Each of the following names is wrong. Draw structures based on them, and correct the names:(b) 1,1,1-trimethylheptane
devlian [24]

The correct IUPAC name of 1,1,1-trimethylheptane is 2,2-dimethyloctane.

<h3>IUPAC NAME:</h3>

It is systematic way of nomenclature of organic compounds.

It is based on the position of functional groups, preference of the functional group, long or short chain of carbon, preference of double bond, single and triple bond, branching of carbon chain, etc.

The given compound is 1,1,1-trimethylheptane.

The given name is wrong according to IUPAC name because the numbering of carbon atom should be done in that way in which the carbon atom chain is largest.

Here, in this case the numbering is done from right side. Thus the largest carbon chain have 8 carbon atom.

If the numbering is done according to the question, number of carbon atom in straight chain is 7.

Thus, we concluded that the Correct IUPAC name of 1,1,1-trimethylheptane is 2,2-dimethyloctane.

What volume will 1.27 moles of helium gas occupy at 80.00 °C and 1.00 atm?
White raven [17]

Answer:

36.8 L

Explanation:

We'll begin by converting 80 °C to Kelvin temperature. This can be obtained as follow:

T(K) = T(°C) + 273

T(°C) = 80 °C

T(K) = 80 + 273

T(K) = 353 K

Finally, we shall determine the volume occupied by the helium gas. This can be obtained as follow:

Number of mole (n) = 1.27 moles

Temperature (T) = 353 K

Pressure (P) = 1 atm

Gas constant (R) = 0.0821 atm.L/Kmol

Volume (V) =?

PV = nRT

1 × V = 1.27 × 0.0821 × 353

V = 36.8 L

Thus, the volume occupied by the helium gas is 36.8 L
