Answer:

N₂ + 3H₂  →  2NH₃

2H₂O →  2H₂ + O₂

CH₄ + 2O₂  →  CO₂ + 2H₂O

Explanation:

A) Make ammonia:

Chemical equation:

N₂ + H₂  →  NH₃

Balanced chemical equation:

N₂ + 3H₂  →  2NH₃

Step one:

N₂   +   H₂      →     NH₃

N = 2                    N = 1

H = 2                    H = 3

Step 2:

N₂   +   3H₂      →          2NH₃

N = 2                              N = 1

H = 2×3 = 6                    H = 3×2 = 6

Step 3:

N₂   +   3H₂      →          2NH₃

N = 2                              N = 1×2 = 2

H = 2×3 = 6                    H = 3×2 = 6

B) separate water:

Chemical equation:

H₂O →  H₂ + O₂

Balanced chemical equation:

2H₂O →  2H₂ + O₂

Step one:

H₂O        →        H₂ + O₂

H = 2                    H = 2

O = 1                     O = 2

Step 2:

2H₂O                →        H₂ + O₂

H = 2×2 = 4                  H = 2

O = 1×2 =2                     O = 2

Step 3:

2H₂O                →        2H₂ + O₂

H = 2×2 = 4                  H = 2×2 = 4  

O = 1×2 =2                     O = 2

C) Combust methane

Chemical equation:

CH₄ + O₂  →  CO₂ + H₂O

Balanced chemical equation:

CH₄ + 2O₂  →  CO₂ + 2H₂O

Step one:

CH₄ + O₂  →  CO₂ + H₂O

C = 1                    C = 1

H = 4                   H = 2

O = 2                    O = 3

Step 2:

CH₄ + 2O₂  →  CO₂ + H₂O

C = 1                     C = 1

H = 4                    H = 2

O = 2×2 = 4          O = 3

Step 3:

CH₄ + 2O₂  →  CO₂ + 2H₂O

C = 1                    C = 1

H = 4                   H = 2×2 = 4  

O = 2×2 = 4         O = 2 + 2 = 4

Give the expression for the solubility product constant for baf2.
svetoff [14.1K]

<span>Solubility product constant (Ksp) is </span>applied to the saturated ionic solutions<span> which are in equilibrium with its solid form. The solid is partially dissociated into its ions.</span><span>

For the BaF, the dissociation as follows;
BaF</span>₂(s) ⇄ Ba²⁺(aq) + 2F⁻(aq)

<span>
Hence,
        Ksp = [Ba</span>²⁺(aq)] [F⁻(aq)]²

The radioisotope phosphorus-32 is used in tracers for measuring phosphorus uptake by plants. The half-life of phosphorus-32 is 1
Harman [31]

Answer:

54 days

Explanation:

We have to use the formula;

0.693/t1/2 =2.303/t log Ao/A

Where;

t1/2= half-life of phosphorus-32= 14.3 days

t= time taken for the activity to fall to 7.34% of its original value

Ao=initial activity of phosphorus-32

A= activity of phosphorus-32 after a time t

Note that;

A=0.0734Ao (the activity of the sample decreased to 7.34% of the activity of the original sample)

Substituting values;

0.693/14.3 = 2.303/t log Ao/0.0734Ao

0.693/14.3 = 2.303/t log 1/0.0734

0.693/14.3 = 2.6/t

0.048=2.6/t

t= 2.6/0.048

t= 54 days

What changes in space result from the death of massive stars?
lana [24]

Whenever the fuel is being used up, a star explodes and the energy leakage from a star's core ceases.

Explanation:

The dying star expands in the "Red Giant," before even the inevitable collapse starts, due to nuclear reactions just outside of the core.

It becomes a white dwarf star when the star has almost the same density as the Sun. If it's much larger, a supernova explosion could take place and leave a neutron star away. However, if it is very large–at least three times the Sun's mass–the crumbling core of the star, nothing will ever stop it from crumbling. The star is imploding into a black hole, an endless gravitational loop in space.
