Explanation:

The amount of heat (q) absorbed by gold could be expressed as:

The sound was repeated because of the phenomenon of echo. The speed of sound in the metal is 800 m/s.

Echo results from the reflection of sound waves. The reason why a sound may be heard twice owes to the phenomenon of reflection which leads to echo.

To determine the speed of sound in the metal;

Length of metal = 1000 m

Time taken between the two sounds = 2.5 s

Using the formula;

V = 2d/t

V = 2(1000)/2.5

V = 800 m/s

Answer:

0.05  moles

Explanation:

In a mole of any substance, there exist 6.02

⋅   10

^23 units of that substance.

So here, we got:

3.01 ⋅ 10^22 Mg atoms ⋅ 1 mole / 6.02 ⋅ 10^23 Mg atoms

= 0.05  moles

Answer:

7.5 seconds

Explanation:

We can use the second equation of accelerated motion

vf = vi + a Δt

We know that the intial velocity (vi) is 30m/s, and the final velocity is 0 since it comes to a stop. We also know that the acceleration is -4m/s.

We can rearrange the equation for Δt (time)

vf = vi + a Δt

vf - vi = a Δt

(vf - vi)/a = Δt

and we can substitute the values into the equation for Δt now

Δt = (vf - vi)/a

Δt = (0 - 30)/-4

Δt = -30/-4

Δt = 7.5

Question

4.

How many grams would 0 .50 moles of Mg be?

Mg has  an atomic weight of 24 so 1 mole of Mg weighs 24 gms

0.50 moles weigh 0.50 X24gm = 12 gm                

5.

10 moles of Al = ? atoms

1 mole = 6.02 X10^23 atoms ...Avogadros number

10 moles is 10 X6.02X10^23 = 6.02X10^24

6.

How many atoms are in 10 moles of Zinc?

a mole is Avogadros number

same as 10 moles of Al,10 moles of Zn=  6.02 X10^24 atoms

7.

If you had 3,5 x 10 - atoms of carbon how many grams would you have?

8.

Given 100g of C = ? atoms

Carbon has an atomic of 12  100 gm of C are 100/12 = 8.33 moles of C

each mole comtains Avogadros number so there are

8.33 X 6.02 X10^23 = 5.01 X10^24 atoms of C

Explanation:

Answer:

H2O is a covalent compound and is called a universal solvent because it dissolves most substances than any other known liquid

The universal solvent, H₂O, is a covalent molecule that dissolves more compounds than any other liquid.

Water makes an excellent solvent because of its physical and chemical composition. In water molecules, hydrogen and oxygen atoms are organized polarly, with hydrogen possessing a positive electric charges and oxide having a negative electrical charge.

Water is referred to be the "universal solvent" because it has a wider range of dissolving abilities than any other liquid. Every living thing on the world requires this. It indicates that wherever water flows, whether through the air, the ground, or our bodies, it carries valuable molecules, minerals, and nutrients.

Answer:

False

Explanation:

If the atom has the same number of protons and electroncs, the atom would have a net charge of 0, meaning it has a neutral charge. A positively charged atom would have more protons (which are positively charged) than electrons (which are negatively charged)

Ammonia gas will diffuse faster than hydrogen chloride gas because the relative molecular mass of ammonia is smaller than that of hydrogen chloride.

According to Graham's law, the diffusion rate of gases is inversely proportional to the square root of their molecular weights.

Thus, the lower the molecular weight of a gas, the faster it will diffuse.

The molecular weight of ammonia is 17 while that of hydrogen chloride is 36.5. Thus, ammonia will diffuse faster than hydrogen chloride.

Explanation:

Answer:

its None of the above.

Explanation:

Answer:

valence electron number

Explanation:

trust me

Valence electron number is the characteristic do electronegativity differences indicate about reactions between atoms. Hence option C is correct.

Electronegativity is defined as the propensity for atoms involved in covalent bonds to draw the bonding electrons. An indicator of how strongly atoms draw bonding electrons to them is their electronegativity. How polar a bond is depends on the difference in electronegativity between two atoms. Since there is no difference in electronegativity between the two identical atoms in a diatomic molecule, the bond is nonpolar or pure covalent.

Valence electron number is defined as an atom's associated outer shell electron that, if the outer shell is open, can take part in the formation of a chemical bond.

Thus, valence electron number is the characteristic do electronegativity differences indicate about reactions between atoms. Hence option C is correct.
