Explanation:

moles = mass/mr

=60.3/28

=2.15 moles

number of particles = moles × 6.02×10^23

= 2.15×6.02×10^23

= 1.29×10^24 atoms

The property of water that helps it maintain a relatively stable temperature is the presence of hydrogen bonds.

Water is an odourless, tasteless and colourless compound that is made up of hydrogen and oxygen atoms.

The properties of water include the following:

The stable temperature of water, that is the ability to have a constant boiling and freezing points, is as a result of the hydrogen bonds existing between the water molecules.

The hydrogen bonds gives water molecules ability to hold heat better than any other substance.

Answer:

192g

Explanation:

so for this find out there moles of CH4 by moles=mass/mr

48/16=3 then use molar ratio 1:2 so times it by 2 which is 6 moles. then uses mass =moles*mr so 6*32=192g is the answer hope this helps to understand.

Answer:

64

Explanation:

The carbons on either side of the double bond are pointed in opposite directions.

Explanation:

AH is negative because the reaction gives out heat (exothermic).

AS is negative because the total entropy of the reactants is greater than that of the products (there are 4 moles of gas on reactant side compared to only 1 mole on the product side). Thus, the reactants are said to be "messier" than the products.

AG is negative at lower temperatures because at low temperatures, -TAS is more negative, resulting in the negative sign of AG.

Answer:

a formula giving the number of atoms of each of the elements present in one molecule of a specific compound.

Answer ; try to understand in the explanation

Explanation: Molecular Formula Definition: An expression which states the number and type of atoms present in a molecule of a substance. Examples: There are 6 C atoms and 14 H atoms in a hexane molecule, which has a molecular formula of C6H14.

For a given valye of l(l shell), values of m are from -l to 0 to l, so m could be; -3, -2, -1, 0, +1, +2, +3.

Easyy!

the value of m is equal to 2l+1 so there must beseven values for m.

m can have values from -l through zero to +l so the values are -3, -2, -1, 0, +1, +2 and +3.

The complete question is as follows: I want to make a homemade cake recipe you need 100 grams of sugar, calculate the moles to which it is equivalent and the number of molecules of sucrose.

Answer: In 100 grams of sugar there are 0.292 moles and the number of molecules of sucrose are [tex]1.76 \times 10^{23}[/tex].

Explanation:

Given: Mass = 100 g

Molar mass of sugar = 342.3 g/mol

As number of moles is the mass of substance divided by its molar mass.

Hence, moles of sucrose are calculated as follows.

[tex]Moles = \frac{mass}{molar mass}\\= \frac{100 g}{342.3 g/mol}\\= 0.292 mol[/tex]

According to mole concept, 1 mole of every substance contains [tex]6.022 \times 10^{23}[/tex] molecules.

Hence, the number of molecules present in 0.292 mol are calculated as follows.

[tex]0.292 mol \times 6.022 \times 10^{23}\\= 1.76 \times 10^{23}[/tex]

Thus, we can conclude that in 100 grams of sugar there are 0.292 moles and the number of molecules of sucrose are [tex]1.76 \times 10^{23}[/tex].

Answer:

the volume of the sound will quarter

Explanation:

As you move far away from the source, the loudness of sound decreases. This is because as the distance from the source increases, the area it covers also increases thereby spreading the energy over a great area leading to lesser loudness and intensity.

As a result of this, sound intensity follows an inverse square law:

I ∝ 1/d²; where I is the intensity and d is the distance from source.

Therefore If a speaker is moved from 2 feet away to 4 feet away (increment of 2 feet), the volume of the sound would quarter (1/2² = 1/4)

C. The final substance in beaker A is a pure substance while in Beaker B is a mixture

Explanation:

A pure substance is a substance that contains a constant and definite proportion of a single substance. Elements and compounds are the two known pure substances while mixtures are substances of different compositions mixed together.

In this question, two beakers; A and B are said to contain different substances. Beaker A contains elemental sulfur (S) that forms a yellow powder while beaker B contains sand and water. From the explanation above, the final substance in beaker A is a pure substance (element) while in beaker B is a mixture of sand and water.

Answer:

H =2; I = 2; J = 2  

Explanation:

Carbon is element 6 in the Periodic Table.  

Start at element 1 (H) and count from left to right until you reach element 6 (C).

You get the electron configuration

C: 1s² 2s²2p².

Thus,

H =2; I = 2; J = 2

Answer:

your simpal answer is 177.32

Answer:

0.32M

Explanation:

Using the following formula;

CaVa = CbVb

Where;

Ca = concentration of acid (M)

Cb = concentration of bass (M)

Va = volume of acid (HCl)

Vb = volume of base (NaOH)

According to this question, the following were given:

Ca = ?

Cb = 2M

Va = 1.824L

Vb = 0.294L

Using CaVa = CbVb

Ca × 1.824 = 0.294 × 2

1.824Ca = 0.588

Ca = 0.588 ÷ 1.824

Ca = 0.32M
