Answer:

the energy used to heat Cu is 27.6 Cal

Explanation:

given data

mass m = 5 g

Specific heat capacity of Cu =  0.092 cal/g

temperature T2 = 80 Celsius

temperature T1 = 20 Celsius

solution

we get here energy used to heat Cu that is express as

Q = m × c × ΔT         ....................1

so here m = mass and c = specific heat capacity

and ΔT = T2 - T1

so put value in eq 1

Q = 5 × 0.092 × (80 - 20)

Q = 27.6 Cal

so that the energy used to heat Cu is 27.6 Cal

Answer:

Sodium oxide reacts exothermically with cold water to produce sodium hydroxide solution. A concentrated solution of sodium oxide in water will have pH 14. ... For example, it reacts with dilute hydrochloric acid to produce sodium chloride solution.

Answer:

The lithosphere is made up of pieces of tectonic plates. These plates are constantly changing and move towards the mantle. Non-stop movement of tectonic plates causes stress on the earth's outermost layer i.e,the crust. When these stresses extends it leads to cause cracks called faults.

Answer:

An orbit is the simple planar representation of an electron. An orbital refers to the dimensional motion of an electron around the nucleus in a three-dimensional motion. An orbital can simply be defined as space or the region where the electron is likely to be found the most.

Explanation:

Answer:

An orbital on the other hand is simply the probable area where one can expect to find the maximum density of electron presence within an atom. An orbit on the other hand is simply present in a body with a certain mass, while an orbital exists for an electron as well as an atom.

Thus, these are the simple differences between Orbit and Orbitals. It is important to know the major differences, you can check out the differences between Orbit and Orbitals below:

Differences between Orbit and Orbitals

Orbit Orbitals

An orbit is the simple planar representation of an electron. An orbital refers to the dimensional motion of an electron around the nucleus in a three-dimensional motion.

It can be simply defined as the path that gets established in a circular motion by revolving the electron around the nucleus An orbital can simply be defined as the space or the region where the electron is likely to be found the most.

The shape of molecules cannot be explained by an orbit as they are non-directional by nature. The shapes of the molecules can be found out as they are directional by nature.

An orbit that is well-defined goes against the Heisenberg principle. An ideal orbital agrees with the theory of Heisenberg’s Principles.

Thus, these are the major differences between Orbit and Orbitals.

Moles of hydronium (H₃O⁺) : 2.5 x 10⁻⁴

Given

pH = 4.3

V sample = 5 L

Required

moles of H₃O⁺(hydronium)

Solution

pH = - log [H₃O⁺]

4.3 = - log [H₃O⁺]

[tex]\tt [H_3O^+]=10^{-4.3}~M=10^{-4.3}mol/L[/tex]

Moles of hydronium for 5 L sample :

Answer:

c ) 8

Explanation:

Given data:

Number of moles of water produced = ?

Moles of hydrogen react = 8 mol

Solution:

Chemical equation:

2H₂ + O₂     →     2H₂O

Now we will compare the moles of hydrogen and water.

         H₂          :         H₂O

          2          :            2

         8           :           8

Thus, 8 moles of water will produced.

Answer:

the divide through osmosis of mitosis or sum

Explanation:

Answer:

In multicellular organisms, cell division aids in the formation of gametes, which are cells that combine with others to form sexually produced offspring. For growth to occur in living organisms, the number of cells have to increase through cell division until it reaches its maximum size. The human body also repairs injuries by means of cell division.

I hope this answer helps you find your answer! Have a great day! :)

Answer:

B. Opposite

Explanation:

When one electron is transferred from sodium to chlorine, a pair of ions with oppositely charged ions is formed.

The electrostatic attraction between the ions forms a covalent bond between them.

Answer:

B. 0.7%

Explanation:

Given data:

Actual boiling point = 82.5°C

Experimental boiling point = 83.1°C

Percent error = ?

Solution:

Formula:

Percent error = ( actual value - experimental value / actual value )×100

by putting values,

Percent error = (82.5°C - 83.1 °C /82.5°C) × 100

Percent error = 0.007 × 100

Percent error = 0.7 %

Negative sign shows that experimental value is greater than accepted value. It can not written in result.

Answer:Lithium atomic orbital and chemical bonding information. There are also tutorials on the first thirty-six elements of the periodic table includes: Li²O

Answer:

Formal charge = valance electron - nonbonding electron - (1/2)bonded electron

For nitrogen atom,

Formal charge = 5 - 2 - (1/2)×6

= 5-2-3

= 0

So, the formal charge on nitrogen atom in HCN is "0".​​​

Explanation:

The formal charge on the N atom of hydrogen cyanide, HCN molecule is 0. Option B is correct.

Formal charge is defined as the individual charge of an atom. It is represented as:

Formal charge = valance electron - nonbonding electron - (1/2)bonded electron

The valence electrons in nitrogen atom is 5, there are 2 non bonding electrons and 6 bonded electrons on N atom in HCN,

Thus, For Hydrogen cyanide molecule, the formal charge on nitrogen atom is calculated as:

Formal charge

= 5 - 2 - (1/2)×6

= 5-2-3

= 0

So, the formal charge on nitrogen atom in HCN is "0".​​​

Explanation:

Rutherford gold experiment gave the explanation to some observations made on atoms.

When he shot the gold foil, most of the [tex]\alpha[/tex]-particles passes through the foil undeflected nor absorbed. This faction of the particles propagated the foil as if there was nothing placed on their path.

The surprising behavior of a few of the [tex]\alpha[/tex]-particles was that they were deflected from their initial path on hitting the gold foil.

This implies that there is a part of the gold foil which has the same charge as the [tex]\alpha[/tex]-particles, and more massive than the particles. Thus, he was able to determine the nucleus of an atom.
