Image 1 shows that the sun is travelling from the left while image 2 shows that the sun is travelling from the right.

We know that the solar system is composed of the sun and the planets. The planets move round the sun in concentric circles and the sun is the focus. This is the heliocentric model of the solar system.

The moon is also a part of the celestial bodies and the light from the moon is dependent on the direction of the movement of the sun. We have to recall that the moon is a non luminous object.

B.) conclusion

Answer:

extensive properties such as mass and volume depend on something like perhaps the amount of what's measured. physical properties can be measured without changing substance chemical identity.

metals are the elements which exhibit degree of metallic behavior is know as metals. non metals are such elements which do not posses any metallic behavior and mekkloids are those elements that posses some of the properties like metal. but they act either like metals or non metals n they also have the same physical properties

Answer:

The density (more precisely, the volumetric mass density; also known as specific mass), of a substance is its mass per unit volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D can also be used.

Answer:

[tex]1.167\times 10^{-3}\ \text{mol/h}[/tex]

Explanation:

[tex]R_1[/tex] = Rate of diffusion of [tex]CO_2[/tex] = [tex]9.31\times 10^{-4}\ \text{mol/h}[/tex]

[tex]R_2[/tex] = Rate of diffusion of [tex]N_2[/tex]

[tex]M_1[/tex] = Molar mass of [tex]CO_2[/tex] = 44.01 g/mol

[tex]M_2[/tex] = Molar mass of [tex]N_2[/tex] = 28.0134 g/mol

From Graham's law we have the relation

[tex]\dfrac{R_1}{R_2}=\sqrt{\dfrac{M_2}{M_1}}\\\Rightarrow R_2=\dfrac{R_1}{\sqrt{\dfrac{M_2}{M_1}}}\\\Rightarrow R_2=\dfrac{9.31\times 10^{-4}}{\sqrt{\dfrac{28.0134}{44.01}}}\\\Rightarrow R_2=1.167\times 10^{-3}\ \text{mol/h}[/tex]

The rate of effusion of the [tex]N_2[/tex] gas would be [tex]1.167\times 10^{-3}\ \text{mol/h}[/tex].

Answer:

all of the above

Explanation:

Answer: The pressure of the gas is 0.34 atm

Explanation:

According to ideal gas equation:

[tex]PV=nRT[/tex]

P = pressure of gas = ?

V = Volume of gas = 605 ml = 0.605 L      (1L=1000ml)

n = number of moles  = 0.00803

R = gas constant =[tex]0.0821Latm/Kmol[/tex]

T =temperature =[tex]39^0C=(39+273)K=312K[/tex]

[tex]P=\frac{nRT}{V}[/tex]

[tex]P=\frac{0.00803\times 0.0821 L atm/K mol\times 312K}{0.605L}=0.34atm[/tex]

The pressure of the gas is 0.34 atm

Answer:

Molar mass: 399.9 g/mol

The mass of iron(III) sulfate is 269 grams.

Explanation:

First of all, you have to find the molar mass of Fe2(SO4)3.

So you find the molar first for each element

However, there are 2 iron atoms, 3 sulfur atoms, and 12 oxygen atoms.(Don't forget the 3 outside the parenthesis of SO4).

So you do this

So the final answer is 399.9 g/mol

Second of all, if you want to find the mass of Fe2(SO4)3, you have to convert from formula units to moles. After that, then you convert from moles to grams.

If you want to convert from molecules to molecules, you have to use Avogadro's number. Avogadro's number is 6.02 x 10^23. Then if you want to convert from moles to grams, you use the molar mass. We already know that the molar mass is 399.9 g/mol.

Therefore, now use dimensional analysis to show your work.

Formula units in the beginning and the moles will cancel out.

But we need to use significant figures with the least digits(which is 4.05) So we round to the nearest whole number.

So the final answer for the mass of iron(III) sulfate is 269 grams(don't forget the units).

By using the given data, the percent yield for sodium carbonate (Na₂CO₃) is equal to 127.

Percent yield of any data can be calculated as:

% yield = (Actual value / Theoretical value) × 100

In the question actual yield of sodium carbonate is given, which is equal to 2.04 grams. And in the table theoretical yield of sodium carbonate also given, which is equal to 1.60 grams.

Now putting these value in the above equation, we get:

% yield = (2.04 / 1.60) × 100 = 127

Hence, percent yield of sodium carbonate (Na₂CO₃) is 127.

a) 0.0006730 can be written in scientific notation as [tex]6.730 \times 10^{-4}[/tex]. The decimal point was moved 4 places to the right, so the exponent is negative 4.

b) 50000.0 can be written in scientific notation as [tex]5.0 \times 10^4[/tex]. The decimal point was moved 4 places to the left, so the exponent is positive 4.

c) 0.000003010 can be written in scientific notation as [tex]3.010 \times 10^{-6}[/tex]. The decimal point was moved 6 places to the right, so the exponent is negative 6.

d) 132.40 can be written in scientific notation as [tex]1.3240 \times 10^2[/tex]. The decimal point was moved 2 places to the left, so the exponent is positive 2.

e) 2232 can be written in scientific notation as [tex]2.232 \times 10^3[/tex]. The decimal point was moved 3 places to the left, so the exponent is positive 3.

Therefore, [tex]6.730 \times 10^{-4}[/tex], [tex]5.0 \times 10^4[/tex], [tex]1.3240 \times 10^2[/tex],  [tex]2.232 \times 10^3[/tex] and  [tex]2.232 \times 10^3[/tex], are the scientific notation for the given numbers.

Explanation:

The reaction between alcohol and acidified potassium dichromate  is a redox reaction. This reaction can be used to detect a drunken driver.

Alcohols can be oxidized to aldehydes, ketones and carboxylic acids depending on the structure of the alcohol. Primary alcohols yield adehydes and carboxylic acids while secondary alcohols are oxidized to ketones.

The colour of the acidified potassium dichromate turns from orange to green when exposed to alcohols from the breath of a drunken driver.
