Answer:

[tex]4.13[/tex] x [tex]10^{2}[/tex] = 413 kg

Explanation:

4.13 x 10 = 41.3 then we multiply 41.3 by 10 agian = 41.3 x 10 = 413

so, we multiplied ten two times that = [tex]10^{2}[/tex]

= 4.13 x [tex]10^{2}[/tex]= 413 kg

Given that 1 kilogram = 1000grams, the value of 413 kilograms in grams, using scientific notation is 4.13 × 10⁵g.

Note that;

1 kilogram = 1000grams

Given that;

Since, 1 kilogram = 1000grams

413 kilograms = ( 413 × 1000 )grams

413 kilograms = ( 413000 )grams

413 kilograms = 4.13 × 10⁵ g

Given that 1 kilogram = 1000grams, the value of 413 kilograms in grams, using scientific notation is 4.13 × 10⁵g.

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".​​​

Answer:

V₂ = 1.41 L

Explanation:

Given data:

Initial temperature = 35°C (35 +273.15 K = 308.15 K)

Initial volume = 1.5 L

Final temperature = 17°C (17+273.15 K = 290.15 K)

Final volume = ?

Solution:

The given problem will be solve through the Charles Law.

According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.

Mathematical expression:

V₁/T₁ = V₂/T₂

V₁ = Initial volume

T₁ = Initial temperature

V₂ = Final volume  

T₂ = Final temperature

Now we will put the values in formula.

V₁/T₁ = V₂/T₂

V₂ = V₁T₂/T₁  

V₂ = 1.5 L × 290.15 K / 308.15 k

V₂ = 435.23 L.K / 308.15 k

V₂ = 1.41 L

Answer:

The possible valances can be determined by electron configuration and electron negativity

Good Luck even though this was asked 2 weeks ago

Explanation:

All atoms strive for stability. The optima electron configuration is the electron configuration of the VIII A family or inert gases.

Look at the electron configuration of the nonmetal and how many more electrons the nonmetal needs to achieve the stable electron configuration of the inert gases. Non metals tend to be negative in nature and gain electrons. ( They are oxidizing agents)

For example Florine atomic number 9 needs one more electron to reach a valance number of 8 electrons to equal Neon atomic number 10. Hence Flowrine has a valance of -1

Oxygen atomic number 8 needs two more electrons to reach a valance number of 8 electrons to equal Neon atomic number 10. Hence Oxygen has a valance charge of -2.

Non metals with a low electron negativity will lose electrons when reacting with another non metal that has a higher electron negativity. When the non metal forms an ion it is necessary to look at the electron structure to determine how many electrons the element can lose to gain stability.

For example Chlorine which is normally -1 like Florine when it combines with oxygen can be +1, +3, + 5 or +7. It can lose its one unpaired electron, or combinations of the unpaired electron and sets of the three pairs of electrons.

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:

2NaBr + I2 Right arrow. 2NaI + Br2

2AgNO3 + Ni Right arrow. Ni(NO3)2 + 2Ag

Explanation:

The activity or electrochemical series is an arrangement of elements according to their order

of reactivity.

If we look at the reactions, one thing that we must note is that the reactions that can occur are those in which an element that is higher in the series displaces another element that is lower in the series.

Br is higher in the electrochemical series than I so it can displace it. Ni is higher than Ag in the electrochemical series hence it can displace it.

Answer: V₂ = 37.71mL

Explanation: To determine the new volume of Helium gas, use the Combined Gas Law, which states the following relationship among pressure, volume and temperature:

[tex]\frac{P_{1}V_{1}}{T_{1}} =\frac{P_{2}V_{2}}{T_{2}}[/tex]

where index 1 relates to the initial state of the gas and index 2 to the final state of the gas.

Temperature is in Kelvin, so:

T = °C + 273

For this situation, standard pressure is 1 atm. Temperatures will be:

T₁ = 20 + 273 = 293 K

T₂ = 91 + 273 = 364 K

Solving:

[tex]V_{2}=\frac{T_{2}P_{1}V_{1}}{P_{2}T_{1}}[/tex]

[tex]V_{2}=\frac{364*1*85}{2.8*293}[/tex]

[tex]V_{2}=\frac{30940}{820.4}[/tex]

[tex]V_{2}=[/tex] 37.71

The new volume of He gas is 37.71 mL.

Answer:

920mL of water

Explanation:

To solve this question we need to find as first the mass that must be added of water to make 1000mL of syrup using specific gravity. Thus, we can know the volume of water that mus be added:

1.31 is 1.31g/mL. In 1000mL = 1310g/1000mL. As the mass added of sucrose is 850g, the mass of water = Volume of water is:

1310g - 850g = 460g of water = 460mL to make 1L, To make 2L the amount of water that must be added is:

460mL * 2  =

The number of milliliters of water are used to prepare two liters of syrup is 920 mL of water.

Given that,

Based on the above information, the calculation is as follows:

1.31 is = 1.31g/mL.

Now

In 1000mL = [tex]1310g \div 1000mL[/tex].

Now if the mass is added so the mass of water should be equivalent to the volume of the water.

= 1310g - 850g

= 460g of water

Now

= 460mL for 1L,

To make 2L the water should be  

= 460mL (2)

= 920mL of water

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:

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:

Specific gravity compares the density of a substance to the density of air.

Specific gravity is compared the density of a substance to the density of water.

Specific Gravity is a dimensionless quantity that can be defined as the ratio of the density of a substance to the density of the water at a particular temperature.

The mathematical formula of the specific gravity can be written as:

Specific gravity = density of substance / density of water

The density of water at 4°C is used as a reference point as water has the highest density of 1000 kg/m³.  Specific gravity or relative gravity does not have any dimension as it is a dimensionless quantity.

Specific gravity is the ratio of a substance’s density to that of water at a specific temperature. The temperature plays an important role in determining the specific gravity of a substance.

Therefore, specific gravity is a characteristic of the substance at a particular temperature and pressure that also affects the specific gravity.

Answer:

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.
