Explain why 6.02x10^23 particles of NaCl has a mass of 58.44 grams

Answer:

going up the slope takes more effort because you are using more of your energy to go up something than going down because of gravity. Gravity wants to pull things down so if you are trying to go up there is more weight than going down.

Answer:

11

Explanation:

Answer:

Atomic number of sodium is 11.

Sodium is a chemical element with the symbol Na and atomic number 11. It is a soft, silvery-white, highly reactive metal. Sodium is an alkali metal, being in group 1 of the periodic table. Its only stable isotope is ²³Na. The free metal does not occur in nature, and must be prepared from compounds.

Answer:

Heating a substance can cause the substance to change state

The way particles move changes when the substance's thermal energy changes.

Particles in all states of matter are constantly

moving.

Those are all correct and apply to water in all three phases

Answer:

option 2nd is correct answer of this question

Some farmers of vegetables and fruits from flowering plants pay beekeepers to bring their beehives to their land each year because flowering plants depend on bees for self-pollination. Therefore, option 2 is correct.

Self pollination is the transfer of pollen grains from the anther of a flower to the stigma of the same flower in the same plant or to a different plant that is genetically similar.

Many crops, but not all, self-pollinate. Beans, broccoli, cabbage, carrots, cauliflower, corn, kohlrabi, onions, and peppers are examples. Apples, cherries, peaches, and pears are among the fruit trees that self-pollinate.

Because flowering plants rely on bees for self-pollination, some farmers of vegetables and fruits from flowering plants pay beekeepers to bring their beehives to their land each year.

Thus, option 2 is correct.

Answer:

In chemistry and physics, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.

The Density of a substance is simply defined as the mass of the subtance per unit volume of the substance i.e

Density = mass /volume

To solve the question given above, we'll begin by calculating the volume of the zinc. This can be obtained as follow:

Density of Zinc = 7.10 g/cm³

Mass of Zinc = 46.77 g

Density = mass /volume

7.10 = 46.77 / Volume

Cross multiply

7.10 × Volume = 46.77

Divide both side by 7.10

Volume = 46.77 / 7.10

Finally, we shall determine the new volume of the water. This can be obtained as follow:

Volume of Zinc = 6.59 cm³ = 6.59 mL

Volume of water = 33.33 mL  

New volume of water = (Volume of Zinc) + (Volume of water)

New volume of water = 6.59 + 33.33

Therefore, the new volume of water is 39.92 mL

Answer:

True

Explanation:

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

No results found for 0.265g of an organic compound produced on evaporation 102cm cube of vapour at 373K and 775mmHg. Percentage composition of the constituent elements are 92.24% C and 7.76% H. Find the molecular mass and molecular formula of the composition..

Results for 0.265g of an organic compound produced on evaporation 102cm cube of vapour at 373K and 775mmHg Percentage composition of the constituent elements are 92.24 C and 7.76 H Find the molecular mass and molecular formula of the composition

Answer:

Using PV=nRT

P=775mmhg/760mmhg

P=1.01atm

so,n=PV/RT

n= (1.01*0.102)/(0.0821*373)

n= 0.00339mole

n =mass/ molecular mass

molecular mass =0.265/0.00339

molecular mass= 78.17

empirical formular = C. H

C= 92.24. 92.24/12= 7.688

H= 7.76. 7.76/1=7.76

therefore Empirical formula is CH

(CH)n=78.16

(12+1)n=78.14

n=78.14/13

n= 6.01

therefore, molecular formula is

C6H6

Answer:

Chemical reaction are irreversible. Some of the example of chemical reaction are cooking, rusting, and burning. During a chemical reaction, the composition of substances changes and the particles rearrange to form a new substance. The new substance formed after chemical reaction of substance has different  physical and chemical properties.

When a chemical reaction occur, the atoms or molecules of the substances change its physical and chemical properties such as while cooking of vegetable, the molecules of vegetable undergo changes in their properties and form a new substance which is different from the earlier.

Explanation:

solute- thing being disolved

solvent- thing doing the disolving

so water is a solvent and salt is solute.

which is A

if my answer helps please mark as brainliest.

In the solution of salt and water, Water is the solvent; Salt is the solute. That is option A.

A solute is defined as the part of a solution that is being dissolved by the solvent. A typical example of solute is base and salts.

A solvent is defined as the dissolving part of a solution which is usually liquid in form. A typical example is water.

Therefore, the solute and solvent of a solution would be salt and water respectively. That is option A.

Answer:

This would depend on the intensity or the size of a fire.

Explanation:

For instance, a small fire could be described as: kindled, flickering, dancing (in the case of a candle flame), smoldering, or crackling.

A medium size fire, such as a camp fire or a fireplace could be described as: crackling, blazing, burning, or roaring.

While a large or very intense fire (such as a forest fire or a house fire) could be described as: roaring, blazing, burning out of control, consuming, raging, or destroying.

If you were more looking for synonyms of ‘fire’, here are a few of my favorites: flame, blaze, incinerate, immolation, and inferno. (Edited to add a few I remembered: pyre, conflagration, and scorching.)
