3295.1 g iron (II) phosphide of Fe₃P

Explanation:

To solve this question we use the Avogadro's number which tell us that in 1 mole of a substance we have 6.022 × 10²³ particles.

In our chase for iron (II) phosphide (Fe₃P) we have:

in if        1 mole of Fe₃P we have 6.022 × 10²³ formula units

then in   X moles of Fe₃P we have 1.0 × 10²⁵ formula units

X = (1 ×  1.0 × 10²⁵) / (6.022 × 10²³)

X = 0.1661 × 10² = 16.6 moles of Fe₃P

number of moles = mass / molecular weight

mass = number of moles × molecular weight

mass of Fe₃P = 16.6 × 198.5 = 3295.1 g

What is the unit for volume?
kondaur [170]

The answer is volume because The base units of length and volume are linked in the metric system. By definition, a liter is equal to the volume of a cube exactly 10 cm tall, 10 cm long, and 10 cm wide. Because the volume of this cube is 1000 cubic centimeters and a liter contains 1000 milliliters, 1 milliliter is equivalent to 1 cubic centimeter.

Hope this helps :)

Draw one line connecting each factor that increases the rate of a
VLD [36.1K]

Answer:

Adding a catalyst - More collisions every second and more collisions with enough energy to break bonds.

Increase in pressure - more collisions every second

Increase in temperature - more collisions every second with enough energy to break bonds

Explanation:

According to the collision theory, chemical reaction occurs as a result of collision between reacting particles. Only particles that possess energy above the activation energy of the reaction can collide and result in product formation. Collision of particles having energy less than the activation energy merely result in elastic collisions.

Adding a catalyst lowers the activation energy of the reaction. If the activation energy is lowered, more reactants collide and more of those collisions now have enough energy to break bonds.

When the temperature is increased, the particles become more energetic hence more collisions with energy to break bonds occur.

Increase in pressure brings the reactant particles into close proximity hence more collisions occur.

What happens when light is not spread out
Maru [420]

Answer:

Spreading out a wave over a larger area just causes the wave strength to weaken, but does not cause gaps to form. Therefore, if you look at photons as waves, spatial gaps never form in light as it travels through free space, no matter how dim it gets.Spreading out a wave over a larger area just causes the wave strength to weaken, but does not cause gaps to form.

Use for questions 1-4
Y_Kistochka [10]

Answer: 1) 1.6 moles of HCl

2) 7.0 moles of HCl

3) 2.4 moles of hydrogen

4) 0.96 moles of HCl

Explanation:

The balanced chemical equation is:

Zn+2HCl\rightarrow ZnCl_2+H_2  

According to stoichiometry :

1 mole of Zn require = 2 moles of HCl

0.8 moles of Zn will require=\frac{2}{1}\times 0.8=1.6moles  of HCl

3.5 moles of Zn will require=\frac{2}{1}\times 3.5=7.0moles  of HCl

According to stoichiometry :

2 moles of HCl produce = 1 mole of H_2

4.8 moles of HCl will require=\frac{1}{2}\times 4.8=2.4moles  of H_2

According to stoichiometry :

1 mole of ZnCl_2 are produced by = 2 moles of HCl

0.48 moles of ZnCl_2 are produced by =\frac{2}{1}\times 0.48=0.96moles  of HCl
