A coffee cup calorimeter is an effective way of measuring the enthalpy of a system because it is a constant pressure calorimeter. This means that, the heat that is measured in a coffee cup calorimeter is equivalent to the change in enthalpy; also its use result in little or no volume change to the system involved.

<h3>What is manufacturing?</h3>

Manufacturing is the creation or manufacturing of items with the aid of resources such as machinery, labor, tools, and chemical or biological processing or formulation. It is the very foundation of the economy's secondary sector. The phrase can be used to characterize a range of human undertakings, from handicraft to high-tech, but it is most usually used in relation to industrial design, which entails the extensive transition of raw materials from the primary industry into finished goods. Such products may be delivered via the tertiary industry to end users and consumers, sold to other manufacturers for the creation of other, more sophisticated products (such as aircraft, home appliances, furniture, and sports equipment), or both (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers).

Sever21 [200]

Answer:

$84,360.00

Explanation:

The cash balance at the end of the year is simply total cash receipts minus total cash payments which is further analyzed below:

Cash receipt from sales=total sales-accounts receivable=$250,000-$18,900=$ 231,100.00

Cash paid for merchandise purchase=purchases-accounts payable=$96,000-$27,000=$69,000

Salaries paid $12,700

Cash from owners is $14,000

cash from borrowing is $14,000

interest paid is $3800

insurance paid is $7,800

Tax paid=(sales-purchases-salaries paid-insurance cost(one year)-interest paid)*tax rate

insurance for one year=$7800*1/2=$3,900

tax paid=($250,000-$96,000-$12,700-$3,800-$3,900)*40%=$53440

Cash balance=$231,100-$69,000-$12,700+$14,000-$14,000-$3800-$7800-$53440=$84,360.00

OleMash [197]

Answer:

Reversionary interest

Explanation:

If Larry Jones gifts land to a school district, but the deed states "for so long as the land is used for a school." Jones owns a reversionary interest.

A reversionary interest can be defined as a property law (deed) which states that when a property such as a land transfer is used on a clause; “for so long as” or “on condition that."

Hence, once the interest of the benefactor comes to an end, the property reverts back to its original owner (grantor). It also gives the grantor's next of kin, successor or heir the power or right to take the property back in the future if promises are broken or the agreement comes to an end.

This ultimately implies that, if a property stated in the deed is not used or used, for certain purposes.

<em>In this scenario, Larry owns a reversionary interest because he gifts a land to the school district, but in the deed he stated "for so long as the land is used for a school." </em>
