What Type Of Thermal Transfer Is A Fan Cooling You Down?

Answers

Answer 1

Answer:  A

Explanation:

Convection is a heat transfer mechanism where heat moves from one place to another through fluid currents. Forced convection is simply using this mechanism in a useful way to heat or cool a home efficiently, such as using a fan.

How many grams are in 0.75 moles of Fe

Answers

Answer:

41.88375 g Fe

Explanation:

Using stoichiometry, we can do this problem. First, we put our given. Then we create an equation using the molar mass of Fe (found on the periodic table, which was 55.845 g Fe), and the resulting equation is:

[tex]0.75 mol Fe * \frac{55.845 g Fe}{1 mol Fe}[/tex]

The mol Fe's cancel, and leave us with:

41.88375 g Fe

A person riding a bike has a mass of 55kg. They are moving with a velocity of 2m/s. What is the Kinetic Energy of the person?

Answers

KE = 1/2mass • velocity^2
So, if we take half of 55, we get 27.5
Next, we take 2, and square it, getting 4.
Lastly, take 27.5, and multiply it by 4, getting 110 Joules, hope this helps and have a great day!

Explanation:

Formula : ½ × mv² (mass×velocity)

½ × 55 × 2²= ½×55×4=110J

(½ is also equivalent to 0.5)

J = Joules

Calculate the amount of work done in lifting a heavy load of 50kg up to the height of 3m?

Answers

amount of work done is equal to l/h

so 50/3=16.66667

round your ans to 2 significant figure

so your ans will be 17m/kg

have to find the lift which would be 50kg times 9.8N/kg which would give you 490N. the formula for work is force times distance. so 490N times 3m= 1470J

what is the primary pigment found in the chlotopast​

Answers

Answer: Chlorophyll is a green photosynthetic pigment found in plants, algae, and cyanobacteria.

Chlorophyll absorbs mostly in the blue and to a lesser extent red portions of the electromagnetic spectrum, hence its intense green color.

Green substance in producers that traps light energy from the sun, which is then used to combine carbon dioxide and water into sugars in the process of photosynthesis Chlorophyll is vital for photosynthesis, which helps plants get energy from light.

Chlorophyll molecules are specifically arranged in and around pigment protein complexes called photosystems, which are embedded in the thylakoid membranes of chloroplasts.

In order to produce CO2, a student put a sample of calcium carbonate in a flask and added hydrochloric acid using the following equation: Ca(CO3) + HCl → H2O + CO2 + CaCl2 The student finds the mass of CO2 generated to be 100 g. If the student began with 200 g of HCl and there was ample CaCO3 left unreacted, what was the percent yield?

Answers

Answer:

82.9% Is the percent yield

Explanation:

First, we need to balance the equation.

Ca(CO3) + 2HCl → H2O + CO2 + CaCl2

Since the problem tells you that the excess reactant is Ca(CO3), we just need to Stoichiometry to solve for the theoretical yield.

[tex]\frac{200g HCl}{1}[/tex] x [tex]\frac{1 mole HCl}{36.46gHCl}[/tex] x [tex]\frac{1 mol CO2}{2molHCl}[/tex] x [tex]\frac{44.01CO2}{1molCO2}[/tex] =120.707 g (theoretical yield)

Take your actual yield of 100g, divide that by 120.707, then multiply that decimical by 100.

How many moles of iron is needed to react completely with 5.00 moles of sulfur to form iron
Fe + S -->
no

Answers

Answer:

5 moles of Fe(II) are required to react completely with the 5 moles of Sulphur

Explanation:

The balanced equation in this question is

Iron + Sulfur = Iron(II) Sulfide

Fe (II) + S --> Fe(II)S

Thus one mole of sulfur reacts with one mole of Fe(II)

Hence, 5 moles of Fe(II) are required to react completely with the 5 moles of Sulphur

Explanation:

The volume is generally measured in Liters, milliliters, cm³, m³, etc. At constant pressure and temperature, the volume produced by six tablets will be 1200 cm³. The correct option is A.

What is volume?

The term volume denotes the capacity that an object can hold. For example if a beaker can hold 100 mL of water then the volume of the beaker is said to be 100 mL. It is represented by the symbol 'V'.

The three dimensional space occupied by the matter is given by the term volume. The SI unit of volume is m³.

Here the volume of three tablets is 600 cm³. Then the volume of one tablet is:

V = 600 / 3 = 200 cm³

Hence the volume produced by six tablets is:

V = 200  × 6 = 1200 cm³.

Thus the volume of six tablets is  1200 cm³.

Thus the correct option is A.
