Iron has a density of 7.86 g/cm3 (1 cm3=1 mL). Calculate the volume (in dL) of a piece of iron having a mass of 3.26 kg . Note t

Mkey [24]

$d=7,86\frac{g}{cm^{3}}=7,86\frac{0,001kg}{0,01dL}=0,786\frac{kg}{dL}\\
m=3,26kg\\\\\\
d=\frac{m}{V} \ \ \ \ \Rightarrow \ \ \ \ V=\frac{m}{d}=\frac{3,26kg}{0,786\frac{kg}{dL}}\approx4,15dL$

Some areas of the Earth receive more solar radiation than others. Which of the following results from the Sun's uneven heating o

STatiana [176]

<em><u>Some areas of the Earth receive more solar radiation than others and this Sun’s uneven heating of the Earth result in </u></em>

i. <em><u>Climate </u></em>

ii. <em><u>Weather </u></em>

iii. <em><u>Ocean currents </u></em>

Further Explanations:

Earth receives varied amount of solar radiation in its different parts. The situation is due to the orbicular shape of the Earth and inclination of the sun during different time of the year. We can see one such example that, during June sun is overheard Tropic of cancer and during September it is overhead Tropic of Capricorn. Because of the inclination,different regions of the Earth experience different climate at the same span of time. This unevenness results in the following phenomenon:

i. Climate:Climate is a continuing average weather condition of a place. Some of the climatological variables commonly measured to determine the climate temperature, moistness, atmospheric pressure, current of air, and precipitation.

ii. Weather: It is defined as the state of atmosphere, describing the degree of heat or coldness, wetness or aridness, calm or stormy. It also refers to daily temperature and rainfall activities.

iii. Ocean Current: It is more or less perpetual or continuous engaged movement of oceanic water flowing on the Earth’s oceans. The current gets created as the resultant of geological forces acting on the oceanic surface.

A barium hydroxide solution is prepared by dissolving 2.06 g of Ba(OH)2 in water to make 32.9 mL of solution. What is the concen

navik [9.2K]

Answer: 1.36 M

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

$Molarity=\frac{n\times 1000}{V_s}$

where,

n = moles of solute

To calculate the moles, we use the equation:

moles of solute= $\frac{\text {given mass}}{\text {molar mass}}=\frac{2.06g}{171g/mol}=0.0120moles$

$Molarity=\frac{0.0120\times 1000}{32.9}=0.364M$

The balanced reaction between barium hydroxide and perchloric acid:

$2HCIO_4+Ba(OH_)2\rightarrow BaCIO_4+2H_2O$

To calculate the concentration of acid, we use the equation given by neutralization reaction:

$n_1M_1V_1=n_2M_2V_2$

where,

$n_1,M_1\text{ and }V_1$ are the n-factor, molarity and volume of acid which is $HClO_4$

$n_2,M_2\text{ and }V_2$ are the n-factor, molarity and volume of base which is $Ba(OH)_2$

We are given:

$n_1=1\\M_1=?\\V_1=8.50mL\\n_2=2\\M_2=0.364M\\V_2=15.9mL$

Putting values in above equation, we get:

$1\times M_1\times 8.50=2\times 0.364\times 15.9\\\\M_1=1.36M$

Thus the concentration of the acid is 1.36 M
