Answer:

The answer to your question is: B

Explanation:

Physical properties are properties that occurs in matter but there is not change in the composition.

A. Solid ice can be very brittle. This is a physical property.

B. Water can form hydrogen and oxygen gas under electrolysis conditions. Here there is a change in the composition of matter, this is an example of chemical property

C. Water can freeze solid at 32 degrees Fahrenheit. This is a physical property.

D. Liquid water can turn into steam in a heated tea kettle. This is a physical property

E. none of the above This option is wrong because option B is correct.

Svetach [21]

Answer:H2=11.4g

CH4=28.6g

Explanation:The complete combustion of the two gases can be represented by a balanced reaction below

1. CH4 +2O2___CO2+2H2O

2.2H2+O2___2H2O

Combining the two we have CH4 +2H2+3O2___

CO2+4H2O

Since the mixture contains 40gof CH4 and 2, therefore 20g of CH4 and 8g of H2 combines.

Calculated from their molecular Mass i.e CH4 12+4×2)=20 and 2H2= 2×2×2=8g

Mass of CH4=20/28×40=28.6g

2H2=8/28×40=11.4g

A pharmaceutical company is making a large volume of nitrous oxide (NO). They predict they will be able to make a maximum amount

iragen [17]

Answer:

The answer is "Option B"

Explanation:

From the query, the following knowledge is derived:

Yield in percentage = 47%

Performance of theory = 4860 g

Actual yield Rate =?

The percentage return is defined simply by the ratio between both the real return as well as the conceptual return multiplied by the 100. It's also represented as numerically:

$Rate = \frac{Existing \ Rate} {Theoretical \ Rate} \times 100$

Now We can obtain the percent yield as followed using the above formula:

$\text{Yield in percentage}= \frac{Actual \ yield \ Rate} {Theorical \ Rate} \times 100$

$47\% = \frac{Actual \ yield \ Rate}{4860}$

The value of the Actual yield Rate = $47\% \times 4860$

$= \frac{47}{100} \times 4860 \\\\ = 2284.2 g$

The Actual yield Rate= 2284.2 g.
