arrange 0.35 kilograms 9.4 grams and 5 grams to smallest to largest

Answer:

The correct answer is C.

Explanation:

To solve this problem, we should first recall possible units for mass and volume.  Mass can be represented with units of grams, kilograms, etc.  Volume has units of cubic meters, cubic centimeters, etc.

Therefore, since we know that density is mass divided by volume, the only answer that makes sense here is C. grams per cubic centimeter (where per signifies that grams are being divided by cubic centimeters).

Answer:

Volume of the [tex]CO_{2}[/tex] gas at 44°C is 258 ml.

Explanation

here,

using Charles' law ,

[tex]\frac{V}{T} =\frac{v}{t}[/tex]

where , V= initial volume          v= final volume

             T=initial temperature    t = final temperature

Given - pressure is constant ,

so , putting the values -

V= 240ml

T= 22 + 273K = 295K                      (since converting celsius into kelvin that

                                                         is +273K )

v =?

t = 44+ 273K = 317K

Now , putting the given values in charles' law ,

[tex]\frac{240ml}{295K} =\frac{v}{317K}[/tex]

240ml x317K = v x 295K     (through cross multiplication )

v =[tex]\frac{240ml\times317K}{295K}[/tex]

= 258ml .

thus , the volume of carbon dioxide in a container at 44°C IS 258ml .

B. A net positive charge

Explanation:

a p e x 2021!

I think its B cause...

When an atom loses an electron, it becomes a cation (positive ion). When an atom gains an electron, it becomes an anion. Ions are created when an atom loses or gains an electron. Atoms can never lose or gain protons, as this would change the fundamental identity of the atom.

if I'm wrong...please don't attack me

The cations are formed when an atom loses electrons.  

• The positive ions produced by the loss of one or more electrons are known as the cations.  

• The most commonly formed cations take place in the case of the elements, which involve the loss of all the valence electrons.  

• The resulting cation exhibits the electronic configuration of the noble gas atom.  

• The negative ions produced from the gain of one or more electrons are known as the anions.  

Thus, the correct answer is option b, that is, the cations form when an atom loses electrons.

For

, there are 16 protons, 18 electrons, and 16 neutrons.

Explanation:

The atomic number,  

Z

, specifies the number of protons, positively charged, massive, fundamental particles present in the sulfur nucleus. This number defines the sulfur atom as a sulfur atom (i.e if there were 17 protons, the atom would be chlorine).

For a neutral atom, if there are 16 positive nuclear charges, there must necessarily be 16 negatively charged particles, 16 electrons, whizzing about the nucleus.

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus.

And thus finally, if we have the

ion, there are 18 electrons, 16 protons, and 16 neutrons.

An atom can be defined by its properties:  

An isotope is represented by the general notation of [tex]_Z^A\textrm{X}[/tex], where X is the symbol of an element.

For the given isotopic specie, [tex]_{16}^{34}\textrm{S}^{-2}[/tex], mass number is 34 and atomic number is 16.

Number of neutrons = Mass number - Atomic number

Put the value in the above formula.

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

From the question

density of metal = 5.78 g/mL

volume = final volume of water - initial volume of water

volume = 24.7 - 22.3 = 2.4 mL

We have

mass = 5.78 × 2.4 = 13.872

We have the final answer as

D. What is the effect of a boat’s shape on its speed?

Explanation:

Kinetic energy can be defined as the energy possessed by an object or body due to its motion. It is the amount of work required to accelerate an object or body with a specific mass from its point of initial rest to a final velocity.

Mathematically, kinetic energy (K.E) is equal to 1/2(mv²).

Hence, the question which would involve the investigation of kinetic energy is "what is the effect of a boat’s shape on its speed?" because speed is directly related to the motion of the boat. Generally, the shape of the hull of a boat has an effect on the speed of the boat.

Answer:A

Explanation: because it represents a salt which is a nonmetal

Answer:

False

Explanation:

Clouds are formed when air contains as much water vapor (gas) as it can hold. This is called the saturation point, and it can be reached in two ways. First, moisture accumulates until it reaches the maximum amount the volume of air can hold. The other method reduces the temperature of the moisture filled air, which in turn lowers the amount of moisture it can contain. Saturation, therefore, is reached through evaporation and condensation, respectively. When saturation occurs, moisture becomes visible water droplets in the form of fog and clouds.

Answer:

h2s

Explanation:

The closest chemical analogue for water is hydrogen sulphide or H₂S. Because, both oxygen and sulfur are same group elements and shows similar properties.

Hydrogen sulphide or  H₂S is a covalent compound formed by the combination of two hydrogens and one sulphur atoms. In this compound, each hydrogen shares one electron to sulfur and sulfur shares its two valence electrons to each hydrogen.

Water is  H₂O, which is formed by the strong hydrogen bonding between hydrogen and oxygen and it exists as liquid mostly. Most of the compounds can be dissolved in water.

Lithium oxide Li₂O is a covalent compound with partial ionic character and it does not exhibit any similarity with water in any case.

Bothe sulfur and oxygen are in 16th group. They are gases with high electronegativity. Hence, both H₂O, H₂S are polar compounds. Both sulfur and oxygen have affinity towards hydrogen. Both have similar shape and bond angle.

Moreover, H₂S can dissolve some minerals and acts as a good solvent like water.

Hence, the better substitute for water is H₂S.
