Answer:

C₄H₆

Explanation:

A hydrocarbon is a molecule that only contains atoms of Carbon and Hydrogen. As you remember, the molar mass of Carbon is 12g/mol and the molar mass of Hydrogen is 1g/mol.

To solve this question we can find the amount of Carbons necessary that doesn't exceed the 54g/mol. That is:

54g/mol / 12g/mol = 4.5

As the molecular formula must be given in whole numbers, the amount of Carbons is 4. This 4 carbons have a mass of:

12g/mol*4 = 48g/mol

And the hydrogens necessaries to suply the molecular mass are:

54 - 48 = 6 hydrogens

That means molecular formula is:

Answer:

kinetic energy possessed by Ceres = 4.806 × 10^(29) J

Explanation:

We are given;

Estimated mass; m = 3 × 10^(21) kg

Orbital speed; v = 17900 m/s

Formula for kinetic energy is;

K.E = ½mv²

K.E = ½ × 3 × 10^(21) × 17900²

K.E = 4.806 × 10^(29) J

Thus;

kinetic energy possessed by Ceres = 4.806 × 10^(29) J

Explanation: Took the test

Answer:

Reaction

Mg+H2SO4 ----》MgSO4+H2

so calculate the moles of magnesium first

moles of magnesium = given mass of mg/molar mass of magnesium

moles = 4/24.30

moles = 0.1646

One mole of magnesium produces one mole of magnesium sulphate

so 0.1646 moles of mg will produce 0.1646 moles of MgSO4

Mass of MgSO4 = 0.1646× 120.366

MgSO4 = 19.81 gm

conclusion the mass of magnesium sulphate that would be obtained from 4g of

magnesium is 19.81 gm!!

I d k it's right or wrong but i tried :)

Answer:

Explanation:

Moles of Pb(NO3)2 =  mass/molecular mass

= 50.0 grams/(207.20*1 + 14.01*2 + 16*6)

= 50.0 grams/331.22

= 0.15 moles

Moles of NaI

= 30/(22.99+126.9)

= 30/149.89

= 0.2 Moles

A. NaI is less 2x Pb(NO3)2 so NaI is the limiting reagent.

B. The ratio is 1 to 2 so there is 0.15 - 0.2/2 = 0.05 mole

or 16.78 grams of Pb(NO3)2 left.

C. As NaI is limiting, only 0.2 Moles of NaNO3 is formed.

Mass =  Moles * Molecular Mass

Molecular Mass of NaNO3 can be calculated as:  

Na - 22.99

N - 14.01

O - 3(16) = 48

23+14+48 = 85gram / mole

Thus, Mass =  0.2*85  = 17 gram of NaNO3

Mass is conserved in a chemical reaction.

Mass of PbI2 can be calculated as:

50+30-16.78-17

= 46.3 gram of PbI2

Mass =  

12.75

Thus, 12.75g of Sodium Nitrate can be formed

Answer:

Explanation:

Pb(NO3)2 (aq) + 2 NaI (aq) --> PbI2 (s) + 2 NaNO3 (aq)

MM for each compound -

Pb(NO3): 207 + 14x2 + 16x3x2 = 331

PI2: 207 + 127x2 = 461

NaI: 23 + 127 = 150

NaNO3: 23 + 14 + 16x3 = 85

Moles of Pb(NO3)2 = 50/331 = 0.15

Moles of NaI = 30/150 = 0.2

Ratio of moles is 1:2

So NaI is limiting

Limited to 0.2/2 = 0.1 mole of Pb(NO3)2

Excess = 0.15 - 0.1 = 0.05 mole

Mass remains = 0.05x331 = 16.55 grams

Moles of NaNO3 formed = Moles of NaI reacted = 0.2

Mass = 0.2x85 = 17 grams

Moles of PbI2 formed = Moles of Pb(NO3)2 reacted = 0.1

Mass = 0.1x461 = 46.1 grams

If 12 grams of NaNO3 actually formed in the reaction,

percent yield = 12/17x100% = 70.6%

P= 10/0.0001

P= 10000

P=1×10^5

Water cannot dissolve all substances that are made from ionic bonds probably because some ionic bonds are too strong for the attractions of water molecules to pull them apart.

However, some ionic bonds formed from ions of elements are unable to be dissolved by water and this is probably attributed to the fact that those bonds are too strong to be pulled apart by water molecules.

Temperature and precipitation

Explanation:

They determine how quickly weathering will be, and what kind of organic material may be available on the inside of the soils.

Temperature and precipitation is the major determining factor in soil formation. They define the type of organic material that can be present inside the soils as well as how rapidly weathering will occur.

The bioactive, porous media that has grown in the top layer of the Earth's crust is known as soil. Being a source of water as well as nutrients, a filter for harmful wastes, a site for their breakdown, and a participant inside the cycle of elements such as carbon through the planet's ecosystem, soil constitutes one of the main substrates of life on Earth.

It has changed as a result of weathering processes influenced by geographical, geologic, biological, and climatic factors. A practical understanding of soils including their management has also developed out of need since the development of agriculture with forestry in the eighth millennium BCE. Temperature and precipitation is the major determining factor in soil formation. They define the type of organic material that can be present inside the soils as well as how rapidly weathering will occur.

Therefore, temperature and precipitation is the major determining factor in soil formation.
