Answer:

Hello There!!

Explanation:

The answer is mitochondria.

Most of the steps of cellular respiration take place in the mitochondria. Oxygen and glucose are both reactants and the main product of cellular respiration is ATP,waste products include carbon dioxide and water.

hope this helps,have a great day!!

Answer:

mitochondria,

Explanation:

Cellular respiration occurs inside cells; specifically, cellular respiration happens inside the mitochondria, the powerhouse of the cell. Cellular respiration is a critical function by which cells release energy for various cellular activities like locomotion, biosynthesis, and even the transportation of molecules between membranes.

2. Calculate how many moles of H2 would be produced if 0.250 mol of Fe reacts completely. (1 mark)

den301095 [7]

Hey there!:

Balanced Equation , for the reaction:

3 H₂SO₄(aq) + 2 Fe(s) → Fe₂(SO₄)₃(aq) + 3 H₂(g)

2 moles Fe ---------------------------------- 3 moles H₂

0.250 moles Fe ---------------------------- ( moles H₂ ) ??

____________________________________________

moles H₂ = 0.250 × 3 / 2

moles H₂ = 0.75 / 2

moles = 0.375 moles of H₂

Hope this helps!

According to the following reaction, how many grams of iron(II) chloride will be formed upon the complete reaction of 21.6 grams

velikii [3]

Answer:

37.58 g of FeCl₂.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

Fe + 2HCl —> FeCl₂ + H₂

Next, we shall determine the mass of HCl that reacted and the mass of FeCl₂ produced from the balanced equation. This is can be obtained as follow:

Molar mass of HCl = 1 + 35.5 = 36.5 g/mol

Mass of HCl from the balanced equation = 2 × 36.5 = 73 g

Molar mass of FeCl₂ = 56 + (2×35.5)

= 56 + 71

= 127 g/mol

Mass of FeCl₂ from the balanced equation = 1 × 127 = 127 g

SUMMARY:

From the balanced equation above,

73 g of HCl reacted to produced 127 g of FeCl₂.

Finally, we shall determine the mass of FeCl₂ produced by the reaction of 21.6 g of HCl. This can be obtained as follow:

From the balanced equation above,

73 g of HCl reacted to produced 127 g of FeCl₂.

Therefore, 21.6 g of HCl will react to produce = (21.6 × 127)/73 = 37.58 g of FeCl₂.

Thus, 37.58 g of FeCl₂ were obtained from the reaction.

A piece of wood near a fire is at 23°c. it gains 1,160 joules of heat from the fire and reaches a temperature of 42°c. the speci

Alex73 [517]

The mass of the piece of wood is 35.58 g.

Joule = M × T × C

Where, M = mass

T = change in temperature(42C-23C=19 C)

C = specific heat capacity = 1.716 joules/gram

Substituting the values in the equation,

1160 = M × 19 × 1.716

M = 1160/32.604 = 35.58 g

Therefore, the mass of the piece of wood = 35.58 g

<h3>What is meant by specific heat capacity?</h3>

A material's specific heat capacity, which is defined as its heat capacity divided by its mass, determines how much energy is required to increase a gram's temperature by one degree Celsius (or one Kelvin)

Mass is the quantity of matter in a physical body.

Which statement best describes how an electromagnetic motor works?

inn [45]

Answer:

Electrons are moved through a magnet, creating a current. That current interacts with a circuit, moving the conductor in the orientation of the field.

Explanation:

Electro magnetic fields are used to create electric current by the movement of electrons. When a coil of wire is wrapped around a magnet it pushes electrons and they flow through a magnet to create current. This current interacts with circuit to move conductor.
