Which statement is correct? Salts are formed by the reaction of bases with water. Most salts are ionic and are soluble in water.

Answer:

11.55 moles of CO2 gas result from 3.85 moles of propane.

15.4 moles of H2O result from 3.85 moles of propane.

b) 0.5176 moles of water result from 0.647 moles of oxygen gas.

0.1294 moles of propane are reacted.

Explanation:

a) Amount of propane = 3.85 moles

The reaction indicates that for every mole of propane, 3 moles of carbon dioxide are produced.

Thus, 3.85 moles of propane yield:

of carbon dioxide.

11.55 moles of CO2 gas result from 3.85 moles of propane.

The reaction also specifies that 1 mole of propane produces 4 moles of water.

Therefore, 3.85 moles of propane will generate:

of water.

15.4 moles of H2O result from 3.85 moles of propane.

b) Amount of oxygen gas = 0.647 moles

The reaction states that 5 moles of oxygen yield 4 moles of water.

As a result, 0.647 moles of oxygen will produce:

of water.

0.5176 moles of water result from 0.647 moles of oxygen gas.

The reaction indicates that 5 moles of oxygen gas interact with 1 mole of propane.

Then, 0.647 moles of oxygen will cause:

of propane to react.

0.1294 moles of propane are reacted.

Consequently, she feels very anxious because she has 345600 seconds to wait. Explanation: 60 seconds make up 1 minute, and 60 minutes constitute an hour. Each hour has 3600 seconds (60*60) and 24 hours make up a day. Hence, 3600 seconds multiplied by 24 hours results in 1 day equating to 86400 seconds—therefore, over four days, we have 86400 * 4 equating to 345600.

Answer:

The yield percentage of H_2CO_3 is 24.44%

Explanation:

Answer:

The revised net worth rounded to three significant figures is $80.2 billion.

The donation to charity amounts to $100,250,000.

Explanation:

Initial net worth is $77.0 billion.

Stock gains are $3.20 billion.

Calculating new net worth: $77.0 billion + $3.20 billion = $80.20 billion.

Hence, new net worth to three significant figures is $80.2 billion.

One-eighth of a percent is calculated as (1/8 x 1) / 100 = 0.00125.

The charitable contribution amounts to 0.00125 X $80.2 billion = $100,250,000.

Alternatively, $80,200,000,000 divided by 100 results in $802,000,000.

Response: In transverse waves, the movement occurs perpendicular to the vibration source.

In contrast, longitudinal waves oscillate parallel to the source of vibration.

Both types share a common aspect: they facilitate energy transfer within the respective wave forms.
