Answer:

a. H0: σ2 ≤ 625

Explanation:

In statistics, a null hypothesis is an assumption that is used to affirm or deny a particular event that is related to one or more parameters of a population or sample.  It refer tos the statement that the researcher is working to reject, is the commonly accepted fact, it is the opposite of the alternate hypothesis which is the statement the researcher is working to prove as true.

So in this case, we are trying to prove that the variance is significantly more than 625, so that would be our alternate hypothesis, therefore, the already accepted fact is that the variance is less or equal than 625, which is the null hypothesis.

for the given reaction, what volume of o2 would be required to react with 4.8 l of co , measured at the same temperature and pre
SVEN [57.7K]

We can see that 2 moles of The no react with 1 mole of O2 using this equation. 4.8 L NO x 1 L O2 / 2 L NO = 2.4 L of O2 are needed at constant pressure and temperature.

What is an example of pressure?

One can see a simple illustration of pressure by using a knife against a few fruit. If you press the flat side of the knife against the fruit, the top won't be cut. The force is spread more than a wide area (low pressure).

What are different types of pressure?

The physical pressure exerted to an object is referred to as pressure. Per unit area, a parallel force is applied to the surface of the objects. F/A (Force per Area) is the basic formula for pressure.

A chemist burns 650.0 g of C4H8S2 in excess oxygen, according the following balanced chemical reaction:
Andrews [41]

Answer:

952.2g SO3

Explanation:

Molar mass of C4H8S2 is 120.2363 g/mol

Mol in 750.0g = 750.0/120.2363 = 6.238 mol

1mol C4H8S2 produces 2 mol SO3

6.238 mol will produce 2×6.238 = 12.476 mol SO3

Molar mass SO3 = 32+3×16 = 80.0g/mol

Theoretical yield = 12.476×80.0 = 998.08g

The actual yield is 95.4%

Actual mass-produced = 95.4/100×998.08 = 952.2g SO3 produced

Hope it will help you.

The fe2+(aq) solution described in part a was produced by dissolving 4.05 g of ore in acid. what was the percentage of fe by mas
poizon [28]
Percentage by mass is the amount in mass of a component in a mixture per 100 unit of mass of the total mixture. Percentage by mass is the same as  %w/w. In order to determine this value, we need to know the mass of the  substance in question and the total mass of the sample. In this case, we have to know the mass of Fe by doing certain calculations. Then, we divide this value by the total mass given of the ore, 4.05 g and multiply by 100%. It should be expressed as follows:

Percent by mass = mass of Fe in ore / 4.05 g ore sample x 100

However, the question is lacking some information so we cannot really specify the answer.
