What are two reasons a common measuring system is important? Make sure you answer in complete sentences.

1 answer:

5 0

For the answer to the question above, t<span>he use of a common measuring system makes it easier for people from different countries to communicate with each other. And also, the use of a common measuring system means a measurement in that unit has the same value anywhere in the world.

For more information,
</span>1) It allows for international cooperation. This means that for example, you can understand and work with other people's results, you can cooperate with other people in production of goods (if you produce one part of something and they produce another) and you can repeat their experiments to see if their results were sound

2) It reduces errors caused by not rigorous measurement: a common measurement supports more exact specification of the measuring units, since many people work towards specifying it exactly.

Of the below gases, which would deviate most from ideal gas behavior? CO O2 NH3 SF4

Vlad [161]

Answer:

For gases such as hydrogen, oxygen, nitrogen, helium, or neon, deviations from the ideal gas law are less than 0.1 percent at room temperature and atmospheric pressure. Other gases, such as carbon dioxide or ammonia, have stronger intermolecular forces and consequently greater deviation from ideality.

Name the following alkyne: CH3CH₂C = CCH₂CH₂CH3

liubo4ka [24]

The given alkyne is Option A 3-heptyne

<h3>What is an Alkyne ?</h3>

The hydrocarbon having at least one C-C triple bond is called an Alkyne.

It has the general formula of $\rm C_n H_{2n+2}$ .

In the question it is being mentioned that it is an alkyne so there will be a triple bond and not a double bond.

It has been asked in the question that

CH3CH₂C ≡ CCH₂CH₂CH3 is which alkyne from the given option.

The counting of the Carbon chain is done from the left side and the Triple bond is at the 3rd Carbon , so 3-heptyne .

The amount of fat recommended for somone with a daily diet of 2000 Calories is 65 g. What percent of the calories in this diet w

Doss [256]

Answer:

29.575%

Explanation:

Data provided:

Calories taken in daily diet = 2000

Recommended amount of fat = 65 grams

Average number of calories for fat = 9.1 calories / g

Thus,

Number of calories in the diet with average number of calories for fat

= Recommended amount of fat × Average number of calories for fat

= 65 × 9.1

= 591.5 calories

Therefore,

the percentage of calories in his diet supplied = ( 591.5 / 2000 ) × 100

= 29.575%

Rank the following substances in order from most soluble in water to least soluble in water: methane, CH4; 2-butanol, C4H9OH; ma

inna [77]

Answer:

MgCl2 > C4H9OH > CH4 > C3H8.

Explanation:

Alkanes do not form hydrogen bonds and are insoluble in polar solvents e.g water. The hydrogen bonds between water molecules are move away from an alkane molecule and this worsens as their Carbon chain / molecular weight increases.

MgCl2 is soluble in water. Water essentially breaks down the ionic crystal lattice and the resulting solution is slightly basic.

Alcohols are generally soluble in water and this is because of the -OH group and its ability to form hydrogen bonds with water molecules. As applied to alkanes, as the carbon chain in the alkyl group increases, the solubility decreases.

From the most soluble to the least soluble,

MgCl2 > C4H9OH > CH4 > C3H8.
