Colby wants to learn more about the feeding habits of ants.
emmasim [6.3K]

Answer:

a. form a hypothesis, conduct an experiment, record data, make a conclusion

Explanation:

Performing scientific investigations involved following the SCIENTIFIC METHOD, which is a rule or guideline followed in order to discover knowledge about natural phenomena. The scientific method has been divided into steps viz:

- Making observation/asking questions: In this case, the problem is HOW ANTS FEED.

- Formulating hypothesis: The hypothesis is a testable explanation given to solve the asked question.

- Testing hypothesis: The hypothesis must be able to be tested via conducting an experiment.

- Analyze result: The results of the test is recorded and analysed as data.

- Make conclusions: The conclusion either accepts or rejects the hypothesis depending on the result of the experiment.

Therefore, based on this; form a hypothesis, conduct an experiment, record data, make a conclusion are the steps Colby should take to best study the feeding patterns of ants

2.61 kilograms of water in a container have a pressure of 200 kPa and temperature of 200°C . What is the volume of this containe
Arisa [49]

<u>Answer:</u> The volume of the container is 2.8497m^3

<u>Explanation:</u>

To calculate the volume of water, we use the equation given by ideal gas, which is:

PV=nRT

or,

PV=\frac{m}{M}RT

where,

P = pressure of container = 200 kPa

V = volume of container = ? L

m = Given mass of water = 2.61 kg = 2610 g   (Conversion factor: 1kg = 1000 g)

M = Molar mass of water = 18 g/mol

R = Gas constant = 8.31\text{L kPa }mol^{-1}K^{-1}

T = temperature of container = 200^oC=[200+273]K=473K

Putting values in above equation, we get:

200kPa\times V=\frac{2610g}{18g/mol}\times 8.31\text{L kPa }\times 473K\\\\V=2849.7L

Converting this into cubic meter, we use the conversion factor:

1m^3=1000L

So, \Rightarrow \frac{1m^3}{1000L}\times 2849.7L

\Rightarrow 2.8497m^3

Hence, the volume of the container is 2.8497m^3

Suppose a sodium hydroxide solution was standardized against pure solid primary standard grade KHP. If 0.4798 g of KHP required
Readme [11.4K]

Answer:

The NaOH solution has a molarity of 0.052 M

Explanation:

<u>Step 1:</u> Data given

Mass of KHP = 0.4798 grams

Volume of NaOH= 45.22 mL = 0.04522 L

Molar mass of NaOH = 40 g/mol

Molar mass of KHP = 204.22 g/mol

<u>Step 2</u>: Calculate moles of KHP

Moles KHP = mass KHP / Molar mass KHP

Moles KHP = 0.4798 grams / 204.22 g/mol

Moles KHP = 0.00235 moles

<u>Step 3</u>: Calculate moles of NaOH

KHP here acts as a mono-acid so, the number of moles of NaOH = number of moles KHP = 0.00235 moles

<u>Step 4: </u>Calculate molarity of NaOH

Molarity NaOH = moles NaOH / volume NaOH

Molarity NaOH = 0.00235 moles / 0.04522 L

Molarity NaOH = 0.052 M

The NaOH solution has a molarity of 0.052 M
