what is the environmental effect of 3NaCl

Answers

Answer:

Sodium and chloride ions separate when salts are dissolved in water. The dissolved sodium and chloride ions, in high concentrations, can displace other mineral nutrients in the soil. Plants then absorb the chlorine and sodium instead of needed plant nutrients such as potassium and phosphorus, leading to deficiencies.

Some power plants burn coal to produce electricity. The energy released from coal being burned is used to change water into steam. The steam spins turbines of large generators that produce electricity. Which energy transformations occur when coal is used to produce electricity?

Answers

Answer:

Steam thus released transforms heat energy from burning coal into mechanical energy that in turn spins the turbine engine. The kinetic energy of the spinning turbine does work in a generator and then the generator that turns this work into electric energy.

The boiling point of water is 100.0*C, yet a student measured it to be 101.3*C. Calculate the percent error of the student's measurement.

Answers

Answer:

Percent error = 1.3%

Explanation:

Given data:

Actual value of boiling point = 100.0 °C

Measured value = 101.3 °C

Percent error = ?

Solution:

Formula:

Percent error = ( Measured value - Actual value / Actual value ) × 100

Now we will put the values in formula.

Percent error =  101.3 °C - 100.0 °C / 100.0 °C × 100

Percent error =  1.3  °C / 100.0 °C × 100

Percent error =  0.013  × 100

Percent error = 1.3%

Thus, percent error is 1.3.

The volume of a sample of gas measured at 27 °C is 10.0 dm . What is the temperature when the volume is reduced to 9.0 dm at the same pressure?

Answers

The second temperature of the sample of gas is 24.3°C

The calculation can be done as follows

T1= 27 °c

T2= ?

V1= 10 dm

V2= 9 dm

V1/T1= V2/T2

10/27= 9/T2

Cross multiply

10 ×T2= 9 × 27

T2= 9 × 27/10

= 243/10

= 24.3 °C

Hence the second temperature is 24.3°C

does the ratio of neutrons to protons affect the stability of the nucleus ?

Answers

The ratio of neutrons to protons (n/p) is a successful way in predicting nuclear stability. This ratio is close to 1 for atoms of elements with low atomic numbers (of less than about 20 protons). The n/p ratio steadily increases as the atomic number increases past element 20 (calcium) to about element 84 (polonium).
