Answer:

Liquid cannot expand because it can only take up space based on the quantity of the liquid. For example, half a glass of water cannot expand to completely fill the glass because there's only half a glass of water.

I hope this helps! :)

While soils are an important part of the global carbon cycle, they are not a part of the nitrogen and sulfur cycles.
Vladimir79 [104]

The correct answer is - False.

The soils are part of most of the major cycles that take place on the Earth, mainly because they are in touch with the other spheres. The carbon dioxide, as well as the nitrogen and the sulfur cycles too, end up in the soil in more cases than not during their cycles. While some are formed in it and than released, like the sulfur, the carbon mostly gets in it though the roots of the plants, as well as the decomposing organisms, and the nitrogen ends up in the soil with the water.

The soil is one of the most important pieces in the cycles of most of the gases on Earth, and without it, some will not even be possible.

What is the pH of 0.0001 M NaOH
kow [346]
Well. NaOH is a base. That's the first thing you need to watch for.
So to find the pOH, you take -log(.0001)
that would be 4. So now you have the pOH and <u>you still need to find the pH
</u>To find pH from pOH, you take 14(the maximum pH,sorta)-pOH(in this case 4)
14-4=10 The pH of NaOH is 10

What are the answers to these?
antiseptic1488 [7]

Answer: 1. AgF + CaCl2 = AgCl + CaF2

2. C2H4 +O2 = CO2 +H2O

3. K2S = K+S

4. O2 + Mg = MgO

5. Mg + AlBr3 = MgBr2 + Al

6.C2H6O + O2= CO2 + H2O

7.Li2SO4 + MgCl2= Li2SO4 + MgCl2

8.HCl + Zn= H2 + ZnCl2

Explanation:

Balance the equation

Write down your given equation.

Write down the number of atoms per each element that you have on each side of the equation.

Always leave hydrogen and oxygen for last.

If you have more than one element left to balance:

Add a coefficient to the single carbon atom on the right of the equation to balance it with the 3 carbon atoms on the left of the equation.

Balance the hydrogen atoms next.

Balance the oxygen atoms.

Gallium is produced by the electrolysis of a solution made by dissolving gallium oxide in concentrated NaOH ( aq ) . Calculate t
Sedbober [7]

Answer:

Approximately 6.30\times 10^{-3}\;\rm mol.

Explanation:

The gallium here is likely to be produced from a \rm NaGaO_2\, (aq) solution using electrolysis. However, the problem did not provide a chemical equation for that process. How many electrons will it take to produce one mole of gallium?

Note the Roman Numeral "\mathtt{(III)}" next to \rm Ga.  This numeral indicates that the oxidation state of the gallium in this solution is equal to +3. In other words, each gallium atom is three electrons short from being neutral. It would take three electrons to reduce one of these atoms to its neutral, metallic state in the form of \rm Ga\, (s).

As a result, it would take three moles of electrons to deposit one mole of gallium atoms from this gallium \mathtt{(III)} solution.

How many electrons are supplied? Start by finding the charge on all the electrons in the unit coulomb. Make sure all values are in their standard units.

t = \rm 80.0\; min = 80.0\; min \times 60\;s \cdot min^{-1} = 4800\; s.

Q = I \cdot t = \rm 0.380 \; A \times 4800 \; s = 1.824\times 10^3\; C.

Calculate the number of electrons in moles using the Faraday's constant. This constant gives the size of the charge (in coulombs) on each mole of electrons.

\begin{aligned} n(\text{electrons}) &= \frac{Q}{F} \cr &= \rm \dfrac{1.824\times 10^3\; C}{96485.332\; C \cdot mol^{-1}}\cr &\approx \rm 1.89\times 10^{-2}\; mol \end{aligned}.

It takes three moles of electrons to deposit one mole of gallium atoms \rm Ga\, (s). As a result, \rm 1.89\times 10^{-2}\; mol of electrons would deposit \displaystyle \rm \frac{1}{3}\times 1.89\times 10^{-2}\; mol \approx 6.30\times 10^{-3}\; mol of gallium atoms \rm Ga\, (s).
