What is the reaction for C + H₂ → CH4

Chemistry
1 answer:
brilliants [131]2 years ago
6 0

Answer:

synthesis/combination

Explanation:

There are 5 main types of reactions.

combination/synthesis, decomposition, single-replacement, double-replacement, and combustion

synthesis/combination -  A+B → AB

Decomposition - AB → A+B

single- replacement - A + BC → AC + B

double replacement - AB + CD → AD + CB

combustion - example - C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g)

If you wanted to balance this

the answer would be C + 2H_{2} → CH_{4}

What if there was an inverse relationship between the temperature and the volume? How do you think the world might be different?
kari74 [83]

If there was an inverse relationship between the temperature and the volume, our daily lives change because in high temperature things will contract.

<h3>What if there was an inverse relationship between the temperature and the volume?</h3>

If there was an inverse relationship between the temperature and the volume then with increasing temperature decrease occur in the volume of a substance. If this type of relationship is present in the world, the objects will contract when the temperature is high and expand when the temperature is low which make the solid materials expand at winter and contract at summer season.

So we can conclude that if there was an inverse relationship between the temperature and the volume, our daily lives change because in high temperature things will contract.

Why does oxygen have a higher electronegativity compared to chlorine?
bezimeni [28]

Answer:

The  electronegativity   of fluorine  compare  to the  electronegativity   of oxygen and chlorine as below

Explanation:

Fluorine  has the highest electronegativity than oxygen, and  chlorine.

 Explanation

Generally  the  electronegativity  increase   across the period ( from the left to the right)  and  decreases down  the group.

Both oxygen and fluorine  are in period 2   in  periodic   table. since  fluorine is on  fur  right side as compared to oxygen , fluorine has higher  electronegativity than  oxygen.

On the  other side  Fluorine  and  chlorine are  in the same group in periodic table. fluorine  is at  the top of  the group  while chlorine  is at  the bottom therefore fluorine has  higher electronegativity  than chlorine.

What is the freezing point (°C) of a solution prepared by dissolving 11.3 g of Ca(NO3)2 (formula weight = 164 g/mol) in 115 g of
Citrus2011 [14]

Answer:

freezing point   (°C) of the solution =  - 3.34° C

Explanation:

From the given information:

The freezing point (°C) of a solution can be prepared by using the formula:

\Delta T = iK_fm

where;

i = vant Hoff factor

the vant Hoff factor is the totality of the number of ions in the solution

Since there are 1 calcium ion and 2 nitrate ions present in Ca(NO3)2, the vant Hoff factor = 3  

K_f = 1.86 °C/m

m = molality of the solution and it can be determined by using the formula

molality = \dfrac{mole \ of \ solute }{kg \ of \ solvent }

which can now be re-written as :

molality = \dfrac{mole \ of \ Ca(NO_3)_2}{kg \ of \  water}

molality = \dfrac{\dfrac{mass \ of \  \ Ca(NO_3)_2}{molar \  mass of \ Ca(NO_3)_2} }{kg \ of \  water}

molality = \dfrac{\dfrac{11.3 \ g }{164 \ g/mol} }{0.115 \ kg }

molality = 0.599 m

∴

The freezing point (°C) of a solution can be prepared by using the formula:

\Delta T = iK_fm

\Delta T =3 \times (1.86 \ ^0C/m) \times (0.599 \ m)

\Delta T =3.34^0 \ C

\Delta T = the freezing point of water - freezing point of the solution

3.34° C = 0° C -  freezing point of the solution

freezing point  (°C) of the solution =  0° C - 3.34° C

freezing point   (°C) of the solution =  - 3.34° C
