Answer:transpiration

Explanation:

The water eventually is released to the atmosphere as vapor via the plant's stomata — tiny, closeable, pore-like structures on the surfaces of leaves. Overall, this uptake of water at the roots, transport of water through plant tissues, and release of vapor by leaves is known as transpiration.

In a lab in New York, Thomas and Nikola collected data over several trials. Thomas recorded his measurements as 10.0 A, 11 A, an

Anna11 [10]

Nikola's reading has a lower range and it is logical to conclude that his reading is more precise.

Explanation:

Precision is the ability to reproduce the same set of result from a measurement. The more repeatability a measurement is, the more precise it is.

From the given pool of data, it is easy to determine which set of data is more precise over the other.

Thomas measurements: 10.0 A, 11 A, and 8 A

Nikola measurements: 9.0 A, 9.2 A, 8.8 A

Using the range method, it is possible to find the precision in this pool of data.

Method and Solution:

Find the range of the sample:

Range = highest value - lowest value

Thomas measurement; Range = (11-8)A = 3.0A

Nikola measurement; Range = (9.2-8.8)A = 0.4A

Find the mean of the samples:

Mean of Thomas measurement = $\frac{10 + 11+ 8}{3}$ = $\frac{29}{3}$ = 9.7A

Mean of Nikola measurement = $\frac{9+ 9.2+ 8.8}{3}$ = $\frac{27}{3}$ = 9A

Now let us quote the range of value of the mean of each measurement:

Thomas 9.7±3.0A

Nikola 9.0± 0.4A

Nikola's reading has a lower range and it is logical to conclude that his reading is more precise.

What mass of sodium hydroxide is needed to neutralise 24.5kg of sulfuric acid <br> H2SO4 + N2 = 2NH3

sveticcg [70]

Answer:

23.92 g

Explanation:

Molar mass of H2SO4 = (2×1)+32+(16×4)= 2+32+48= 82g/mol

H2SO4 + 2NaOH ---> Na2SO4 + 2H2O

I mole of H2SO4 = 2 moles of NaOH

24.5/82 = 24.5/82 × 2

= 0.598 moles of NaOH will neutralize

Mass= mole× molar mass

Molar mass of NaOH= 23+16+1 = 40g/mol

Mass= 0.598 × 40 = 23.92g of NaOH

What procedure could a student use to examine an intensive property of a rectangular block of wood

photoshop1234 [79]

An intensive property does not change when you take away some of the sample. The procedures that a student could use to examine the intensive property of a rectangular block of wood are the hardness, color, density and molecular weight.
