Answer:

The wacelength of this note is 87.5 cm

Explanation:

Step 1: Data given

Frequency of the middle G note = 392.00 Hz

The speed of sound in air is 343.06 m/s

Step 2: Calculate the wavelength

The wavelength of a sinusoidal wave travelling at a speed c and frequency f is c/f.

In this case c is the speed of sound of 343.06m/s and the frequency is 392.00 Hz.

So the wavelength would be c/f = 343.06 / 392.00 = 0.875 m

0.875 m = 87.5 cm

The wacelength of this note is 87.5 cm

Answer:

(See explanation for further details)

Explanation:

1) The quantity of moles of sulfur is:

$n = \frac{1.20\times 10^{24}\,atoms}{6.022\times 10^{23}\,\frac{atoms}{mol} }$

$n = 1.993\,moles$

2) The number of atoms of helium is:

$x = (1.5\,moles)\cdot \left(6.022\times 10^{23}\,\frac{atoms}{mole} \right)$

$x = 9.033\times 10^{23}\,atoms$

3) The quantity of moles of carbon monoxide is:

$n = \frac{4.15\times 10^{23}\,molecules}{6.022\times 10^{23}\,\frac{molecules}{mol} }$

$n = 0.689\,moles$

4) The number of molecules of sulfur dioxide is:

$x = (2.25\,moles)\cdot \left(6.022\times 10^{23}\,\frac{molecules}{mole} \right)$

$x = 1.355\times 10^{24}\,molecules$

5) The quantity of moles of sodium chloride is:

$n = \frac{2.4\times 10^{23}\,molecules}{6.022\times 10^{23}\,\frac{molecules}{mol} }$

$n = 0.399\,moles$

6) The number of formula units of magnesium iodide is:

$x = (1.8\,moles)\cdot \left(6.022\times 10^{23}\,\frac{f.u.}{mole} \right)$

$x = 1.084\times 10^{24}\,f.u.$

7) The quantity of moles of potassium permanganate is:

$n = \frac{3.67\times 10^{23}\,f.u.}{6.022\times 10^{23}\,\frac{f.u.}{mol} }$

$n = 1.214\,moles$

8) The number of molecules of carbon tetrachloride is:

$x = (0.25\,moles)\cdot \left(6.022\times 10^{23}\,\frac{molecules}{mole} \right)$

$x = 1.506\times 10^{23}\,molecules$

9) The quantity of moles of aluminium is:

$n = \frac{3.67\times 10^{23}\,atoms}{6.022\times 10^{23}\,\frac{atoms}{mol} }$

$n = 0.609\,moles$

10) The number of molecules of oxygen difluoride is:

$x = (3.52\,moles)\cdot \left(6.022\times 10^{23}\,\frac{molecules}{mole} \right)$

$x = 2.120\times 10^{24}\,molecules$

Calculate the mass of O2 produced if 3.450 g potassium chlorate is completely decomposed by heating in presence of a catalyst (m

sergiy2304 [10]

The reaction is:

2 KClO3(s) → 3 O2(g) + 2 KCl(s) <span>

<span>A catalyst simply lowers the activation energy so MnO2 is not part of the overall reaction.

By stoichiometry:

<span>3.45 g KClO3 x 1 mol/ 122.55g KClO3 x 3 mol O2/ 2 mol KClO3 x 31.99g/ 1 mol O2 = 331.096/ 245.1 = 1.35 grams O2 produced

Answer:
1.35 grams O2</span></span></span>

Newbie Here pls.. HELP me

polet [3.4K]

Answer:

1. Litres

2. minutes

3. Kelvin (K)

4. Kilometer/hour

5. hours

6. Litre

7. metre

8. metre

9. Litres

10. milliliters

Explanation:

1. Coca-Cola is a liquid substance, hence, its volume must be measured in LITRES.

2. This question is related to time I.e. being early, hence, the unit of measurement is MINUTES.

3. The unit of temperature is Kelvin (K). Therefore, water boils at 373K

4. This question is related to speed, whose unit of measurement is kilometer/hour (km/hr).

5. A movie runs with time, which is measured in HOURS.

6. Mineral water is a liquid, which can only be bought per volume. Hence, the appropriate unit is LITRE.

7. Height is measured in metres (m). Therefore, one can say that " the height of your younger brother is 10metres"

8. The length of a substance is also measured in metres.

9. Volume is measured in LITRES

10. Cough syrup is a drug whose volume is quantified by millilitres i.e. a thousandth litre
