What are the two processes of ocean to cloud?

Answer: 4,000 grams of NaCI

Explanation:

We know that there are 400g of NaCI in one drop.

This bottle has 10 drops of this item.

So, we have to multiply the amount of NaCI in a drop by the amount of drops.

400 x 10 = 4,000.

The answer to the question is 4,000. Hope this helps!

Answer:

Explanation:

no of moles of C2H6=10/30=0.33

complete combustion of 2 moles of ethane produce 4 moles of CO2 therefore 0.33 moles of C2H6 produced 0.66 moles of CO2

now moles =given mass/molar mass

mass= moles*molar mass

mass of CO2=0.67*44=29.48 g

Answer:

Nonmetals form negative ions (anions). A nitrogen atom must gain three electrons to have the same number of electrons as an atom of the following noble gas, neon. Thus, a nitrogen atom will form an anion with three more electrons than protons and a charge of 3−.

Ionic

Explanation:

Because sulphur is a non-metal and cesium is part of the group 1 Alkali Metals, this creates an ionic bond

Ionic bonds are created from one metal and one non-metal element.

Al(OH)₃

Total molecular weight = 27 + 3 x ( 16+1)

= 78

Al = 27

% of Al = 27 x 100 / 78 = 34.61%

O = 48

% of O = 48 x 100 / 78 = 61.55 %

H = 3

% of H = 3 x 100 / 78

= 3.84%

Al = 34.61%.

O = 61.55%.

H = 3.84%.

A geological event is a brief, spatially diverse, dynamic and ongoing occurrence in the history of the Earth.

A geological event is a brief, spatially diverse, dynamic (diachronous), and ongoing occurrence in the history of the Earth that aids in the modification of the Earth system and the production of geological strata. The concept of event stratigraphy initially came up as a way to identify, analyse, and correlate how significant physical and biological events have affected the overall stratigraphical record.

Israel's Dead Sea basin Holocene sediments contain seismic activity. This can be considered a record of a geological event, an earthquake, that altered the strata. Geological events can occur over timescales of order of magnitude, from just a few seconds through millions of years, as well as on a variety of spatial scales, from the local to the globe.

1. Volcanoes and minor earthquakes

2. Volcanoes, earthquakes and fold mountains.

3. Earthquakes and fold mountains.

4. Magma from volcanoes is filled with nutrients that makes land fertile.

Therefore, a geological event is a brief, spatially diverse, dynamic and ongoing occurrence in the history of the Earth.

Answer:

The sodium has more moles.

n(Na)=2.09 mole

n(O)=0.999 mole

Answer:

I thin its B im not sure though

Explanation:

The puppies from the same set of parents have different color noses because the pink-nosed puppy and the black nosed puppy inherited different combinations of the genes for nose color from their parents. Thus, the correct option is B.

A gene is the unit of inheritance which is made up of DNA (deoxyribonucleic acid). Every person receives two copies or alleles of each gene which is inherited from each of the two parent.

Genes are made up of DNA, so each of the chromosome contains many different genes. Genes carry the information which determines the traits or characteristics that are passed on to their offspring or inherited from the parents.

The puppies from the same set of parents have different colored noses because pink-nosed puppy and the black nosed puppy inherited different combinations of the genes for nose color from their parents.

Answer:

It will remain the same

Explanation:

The equilibrium constant of the reaction will remain the same if the concentration of the OH is increased.

Changes in concentration values of any of the reactant does not affect the value of the equilibrium constant.

The equilibrium constant if the concentration of OH − increases through the addition of a small amount of NaOH(aq) is :

- Remains same.

The equilibrium constant of the response will stay the same in case the concentration of the OH is increased.

Changes in concentration values of any of the reactant does not influence the esteem of the equilibrium constant.

The equilibrium constant may be a consistent at a given temperature.

Answer:

-306j

Explanation:

For this question we define an equation:

W = -Pext(Vj-Vi)-----> eqn 1

P = 6atm

Vi = 285 ml

We convert it to litre

= 285/1000 mL

= 0.285 L

Vj = 789 mL

When converted to litre

= 789/1000 mL

= 0.789 L

These values are all going to be put values in the eqn 2 above

W = -Pext(Vj-Vi)

W = -6.0x (0.789L - 0.285L)

W = -3.024

W = -3.024 x 101.33 J

This gives us the answer

W = -306 J

Answer:

b. decreases

Explanation:

i just took a test on it

As you move from N to Bi, the metallic properties of the element decrease. The correct option is B.

Nitrogen is a chemical element, whose chemical element is N. Nitrogen is a gas and its atomic number is 7. It is a non-metal and is present in group 15 of the periodic table.

Bismuth is a chemical element, whose chemical element is Bi. It is a post-transition metal, and it is also present in group 15 of the periodic table near arsenic and antimony. Its atomic number is 83.

Now, nitrogen and bismuth are present in the same line and group. Nitrogen is the first element of the group and going down, there is bismuth present in the group last. So the metallic property decreases from going down the group.

Thus, the correct option is B. decreases.

Answer:

Explanation:

a )

half life = 1600 years

50% in 1600 years

25% in next 1600 years

so 25% in total of 3200 years .

b )

disintegration constant = .693 / half life

= .693 / 1600

λ= 4.33 x 10⁻⁴ year⁻¹

m(t) = [tex]m_0e^{-\lambda t }[/tex]

m₀ is initial mass , λ =  4.33 x 10⁻⁴ year⁻¹

c )

m(t) after 3000 years , t = 3000

m(t) = [tex]m_0e^{-4.33\times10^{-4 }\times 3000 }[/tex]

= [tex]m_0e^{-1.3}[/tex]

= .2725 m₀

percentage of mass remaining = 27.25 %

25% radium-226 remain after 3200 years. 6.82 mg of sample remains after 3000 years. 15 mg of the sample will stay long about 1179. 19 years.

Half life of radium-226 = 1600 years

half-life, in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay.

Calculation of each part can be done as

a )

half-life = 1600 years

50% in 1600 years

25% in next 1600 years

so 25% in total of 3200 years .

b )

Let decay function is

[tex]m(t) = m_o e^{-kt} \ \ \ \ \ ...(i)\\[/tex]

where k is decay constant

At half life,

[tex]m(t) = \frac{m_o}{2},t= 1600\ years\\So,\ \frac{m_o}{2} = m_oe^{-k1600}\\\frac{1}{2} = e^{-k1600}\\[/tex]

applying log on both sides

[tex]ln \frac{1}{2} = lne^{-1600k}\\-0.693147 = -1600 k \\k =\frac {0.693147}{1600}\\k = 4.332\times10^{-4}\\[/tex]

substitute the value of k in equation (i)

[tex]m(t) = m_oe^{-4.332\times10^{-4t}}\\m(t) = 25e^{-0.0004332t}[/tex]

c) when t = 3000 years

[tex]m(t) = 25e^{-0.0004332t}[/tex]

[tex]m(3000) = 25e^{-0.0004332\times3000}[/tex]

remain sample after 3000 years = 6.82 mg

d) when m(t) = 15 mg

[tex]15 = 25e^{-0.0004332t}\\e^{-0.0004332 t} = \frac{15}{25}\\applying\ log\ on\ both\ side\\ln \ e^{-0.0004332t}=ln(\frac{15}{25)}\\-0.0004332t = -0.510825\\t=\frac{0.510825}{0.0004332}\\t= 1179.19 \ years[/tex]
