Is 2 C4H10 + 13 O2 → 8 CO2 + 10 H2O a double replacement?

Chemistry

natulia [17]3 years ago
8 0

Answer:

The answer to your question is No, it is not.

Explanation:

Data

                C₄H₁₀  +  13O₂   ⇒   8CO₂ +  10H₂O

In a double replacement reaction, two reactants interchange cations an example of these reactions are neutralization reactions. In neutralization reactions, an acid and a base react to form a salt and water.

The reaction of this problem is not a double replacement reaction because the products are carbon dioxide and water, not a salt and water.

The reaction of this problem is a combustion reaction.

Why is beryllium-8 different from beryllium-9 in terms of the nuclear particles?
Helen [10]

Answer:

Beryllium-8 (8Be, Be-8) is a radionuclide with 4 neutrons and 4 protons. It is an unbound resonance and nominally an isotope of beryllium. It decays into two alpha particles with a half-life on the order of 10−16 seconds; this has important ramifications in stellar nucleosynthesis as it creates a bottleneck in the creation of heavier chemical elements. The properties of 8Be have also led to speculation on the fine tuning of the Universe, and theoretical investigations on cosmological evolution had 8Be been stable.

Can two or more elements be combined chemically to make a new element??
DENIUS [597]

Elements can be chemically combined into compounds, therefore, a compound consists of two or more elements combined, in definite proportions, by chemical means. Compounds may be formed by combining atoms of their constituent elements by ionic bonds or by covalent bond. No but they can be compounds

Please help I need to draw and label a atom that has 7 protons and 8 neutrons!!!! I will give a brainly
Galina-37 [17]

Answer:

Oxygen

Explanation:

Given the following question:

The following atom has 7 protons (plus charge)
The following atom has 8 neutrons (negative charge)
The following atom has 7 electrons since the number of electrons are equal to the number of protons the atom has.

The following atom is oxygen with a mass number of 16: (see photo below)
Let the red represent protons...
Let the gray represent the neutrons...
Let the blue represent the electrons...

Hope this helps.

It takes 5.54 mL of a 2.18 M NaOH solution to neutralize 6.19 mL of an HCl solution. What is the concentration of the HCl soluti
svetlana [45]

Answer:

2 M

Explanation:

NaOH + HCl --> NaCl + H2O,

5.54 mL = .00545 L,

If we consider 2.18 M, M [molarity] = mol/L, so we have 2.18 mol/L. From this we can get the moles of NaOH.

.00545 L *  2.18 mol/L ≈ .0121 mol

The concentration of HCl can be found from the following:

.0121 mol = .00619(x) [where x = concentration of HCl]

x = 1.955 M ≈ 2 M

We equate the two as we require the same amount in order to neutralize the base.
