Answer:

I believe the answer is A. Organic.

Hope it helps!

Answer:

Organic

Explanation:

living things are organic, so chemical is wrong, detrital is when rocks form from broken down rocks left behind, again not from living things so that's also wrong, that leave Organic and foliated, foliated makes no sense which leave only Organic, so organic will be your answer

Answer:

The molecular weight is [tex]Z = 111.2 \ g/mol[/tex]

Explanation:

From the question we are told that

   The mass of the sample is  [tex]m = 0.98 \ g[/tex]

    The temperature is  [tex]T = 348 K[/tex]

    The volume which the gas occupied is  [tex]V = 265 \ ml = 265 *10^{-3} L[/tex]

     The pressure is  [tex]P = 0.95 \ atm[/tex]

Generally from the ideal gas equation we have that

       [tex]PV = n RT[/tex]

Here n is the number of moles of the gas while the R is the gas constant with value  [tex]R = 0.0821 \ atm \cdot L \cdot mol^{-1} \cdot K^{-1}[/tex]

        [tex]n = \frac{PV}{ RT}[/tex]

=>      [tex]n = \frac{ 0.95 * 265 *10^{-3} }{ 0.0821 * 348}[/tex]

=>      [tex]n = 0.00881 \ mol[/tex]

Generally the molecular weight is mathematically represented as

          [tex]Z = \frac{m}{n}[/tex]

=>      [tex]Z = \frac{0.98 }{0.00881}[/tex]

=>      [tex]Z = 111.2 \ g/mol[/tex]

Answer:

a) number measurement

Explanation:

relating to, measuring, or measured by the quantity of something rather than its quality.

Answer:

number and measurement

Explanation:

Quantitative is an adjective that simply means something that can be measured. For example, we can count the number of sheep on a farm or measure the gallons of milk produced by a cow.

Answer: Matter is heated, and its particles spread out more

Explanation:

Thermal expansion occurs when there's an expansion of an object or material or when an object becomes bigger because of a rise in its temperature. This brings about the faster movement of the heated molecules and the atoms spreading out.

Therefore, the cause and effect of thermal expansion will be that when matter is heated, and its particles spread out more.

Answer:

237.8L of water would need to be added.

Explanation:

The first thing to do is to identify that the equation to be used is M1V1=M2V2. (This equation works because it turns everything into moles which can then be compared).

Then figure out what information you have and what is being found. In this case:

M1 = 54.7 M

V1 = 1092 mL = 1.092 L

M2 = 0.25 M

V2 = unknown

Then solve the equation for whatever you are trying to find.

M1V1=M2V2

V2=M1V1/M2

Now you need to plug everything in.

V2=(54.7M*1.091L)/0.25M

V2=238.93L

That means that the solution needs a volume of 238.7L to gain a molarity of 0.25M but the starting solution already had a volume of 1.092 L meaning that to find the amount of solvent that needs to be added you just subtract the starting volume by the volume that the solution needs to be.

238.93L - 1.091L = 237.8L

Therefore the answer is that 237.8L needs to be added to a 1.092L 54.7M NaCl solution to make the concentration 0.25M.

I hope this helps.  Let me know if anything is unclear.

Plates at our planet's surface move because of the intense heat in the Earth's core

Explanation:

Hopefully this helps, I believe in you! ^^

Answer/Explanation:

movement can be cause by the intense heat in the earth's core, which causes molten rock in the mantle layer to move.  it moves in a pattern called 'convection cell' which can form when the warm material rises, then cools, and eventually sink down.  then the process repeats (cooled, warms up and rises.. etc..)

Answer:

Slower shutter speeds like 1/60 second and slower cause a blurring effect. If you want to take a picture using a slow shutter speed, it is best to mount the camera on a tripod and use image stabilization (such as SteadyShot® technology) to reduce the chance of any unwanted camera movement.

The first big effect of it is motion blur. If your shutter speed is long, moving subjects in your photo will appear blurred along the direction of motion. ... If you use an especially fast shutter speed, you can eliminate motion even from fast-moving objects, like birds in flight, or cars driving past.

Answer:

There are 6 hydrogen atoms.

Explanation:

The formula for an alkyne that has only one triple bond is as follows:

Where n is any natural number greater than 2.

For this problem, n=4. This would mean the formula is:

Thus

Thus the answer is 6, there are 6 hydrogen atoms.

Answer: H2O and NH3 are polar molecules. H2 is a nonpolar molecule but the H-H bond is also nonpolar.

Therefore, the best choice is CCl4. Although the C-Cl bond is polar due to electronegativity differences, the molecule itself is nonpolar because the net dipole moments cancel out, given its tetrahedral molecular structure.

The coefficients used to balance the chemical equation given in the question are 2, 4, 1 (Option A)

Chemical equations are representations of chemical reactions using symbols and formula of the reactants and products.

The reactants are located on the left side while the products are located on the right side.

Reactants —> Products

The balancing of chemical equations follows the law of conservation of matter which states that matter can neither be created nor destroyed during a chemical reaction but can be transferred from one form to another.

Ag₂O —> Ag + O₂

There are 2 atoms of O on the right side 1 on the left. It can be balance by writing 2 before Ag₂O as shown below

2Ag₂O —> Ag + O₂

There are 4 atoms of Ag on the left side and 1 atom on the right side. It can be balance by writing 4 before Ag as shown below

2Ag₂O —> 4Ag + O₂

Now, the equation is balanced.

Thus, the coefficients are: 2, 4, 1

Answer:

4-ethylhex-2-yne

Explanation:

Answer:

1.22 × 10^22 H atoms

Explanation:

From this question, TNT has the chemical formula: C-H5N306. The number of nitrogen atoms in the TNT substance is said to be 7.30 × 10^21 atoms.

The number of hydrogen atoms in the same TNT substance can be got using mole ratio. Based on the chemical formula, the mole ratio of hydrogen to nitrogen is 5:3 i.e. H5N3.

This means that;

Number of atoms of hydrogen = 5/3 of the number of atoms of nitrogen.

Hence, number of H atoms = 5/3 × 7.30 × 10^21

number of H atoms = (7.30 × 5/3) × 10^21

number of H atoms = (36.5/3) × 10^21

number of H atoms = 12.1666 × 10^21

number of H atoms = 1.2166 × 10^22 atoms.

Approximately, number of H atoms in TNT is 1.22 × 10^22 atoms.

CIO decomposes acco to the equation: 2CIO(g) rightarrow CL2(g) + O2(g) The second-order rate constant for the decomposition of CIO is 6950000000 M-1 s-1 at a particular temperature Determine the half-life of CIO when its initial concentration is .0000000185 M

Answer:

7.8 * 10^-3 s

Explanation:

Given that the half life of a second order reaction is obtained from the formula;

t1/2 = k-1[A]o-1

t1/2 = 1/k[A]o

second order rate constant (k) = 6950000000 M-1 s-1

initial concentration ([A]o) =0.0000000185 M

t1/2 = 1/6950000000 * 0.0000000185

Answer:

Explanation:

If we look at the structures of each of the compounds we can be able to deduce the accurate hybridization of each of the atoms listed.

Looking at ClNO - we can see that the nitrogen atom is linked to oxygen by a double bond and linked to chlorine by a single bond retaining a lone pair on nitrogen. Hence the nitrogen is in sp2 hybridized state.

For ClOCl, the compound has a sp3 hybridized oxygen atom linked to two chlorine atoms as expected retaining two lone pairs on oxygen.

For NCOH, the carbon atom is doubly bonded to oxygen hence it is sp2 hybridized.

Explanation:

In a neutralization, the acid, H₂SO₄, reacts with a base, KOH, to produce a salt, K₂SO₄ and water. The reaction is:

H₂SO₄ + 2KOH → K₂SO₄ + 2H₂O

To solve this problem, we need to determine moles of H2SO4 and moles of KOH that reacts to find the moles of sulfuric acid that remains after the reaction:

Moles H2SO4:

0.650L * (0.430mol /L) = 0.2795moles H2SO4

Moles KOH:

0.600L * (0.240mol / L) = 0.144 moles KOH

Moles of sulfuric acid that reacts with 0.144 moles of KOH are:

0.144 moles KOH * (1mol H2SO4 / 2 mol KOH) = 0.072 moles of H2SO4 react.

And remain:

0.2795moles H2SO4 - 0.072moles H2SO4 = 0.2075 moles of H2SO4 reamains.

In 0.650L + 0.600L = 1.25L:

Molar concentration of sulfuric acid:

0.2075 moles of H2SO4 / 1.25L =
