Balanced equation between copper oxide and sulphuric acid

Chemistry
1 answer:
emmainna [20.7K]3 years ago
4 0

Answer:

CuO + H₂SO₄ ⟶ CuSO₄ + H₂O

Explanation:

The most likely reaction is a <em>double displacement</em>, in which Cu and H trade partners.

This gives

CuO + H₂SO₄ ⟶ CuSO₄ + H₂O

The equation is already balanced, so no further work is necessary.

What is the wavelength of electromagnetic radiation with a frequency of 9.23 × 10^-7 Hz?
stich3 [128]

3.25 x 10¹⁴m

Explanation:

Given parameters:

Frequency of the radiation = 9.23 x 10⁻⁷hz

Unknown:

Wavelength of the radiation = ?

Solution:

The velocity of electromagnetic radiation is the same as that of the speed of light in vacuums.

  Velocity = frequency x wavelength.

 Velocity = 3  x 10⁸m/s

Since the unknown is wavelength, we factor it out:

    Wavelength = \frac{Velocity }{frequency}

    Wavelength = \frac{x}{y}\frac{ 3 x 10^{8} }{9.23 x 10^{-7} }

                          = 3.25 x 10¹⁴m

Consider each possible structure of carbon dioxide, c o 2. Determine whether the structure is correct and justify your decision.
Mrrafil [7]

This structure is correct due to the total number of bonds and electrons

We employ the octet rule, which states that all atoms in a compound are expected to follow, to check the accuracy of any chemical structure. The octet rule is precisely satisfied for each atom in the depicted structure of carbon IV oxide. The valence shell of each atom in the molecule is surrounded by eight electrons. We may thus infer that this structure is accurate given the total number of bonds and electrons since CO2 has sixteen valence electrons.

It possesses a negative charge of 1.602176634 coulombs, the basic unit of electric charge, which is comparable to its negative charge. The rest mass of an electron is 9.1093837015 10^-31 kg, or just 1/1,836 the mass of a proton. An electron is therefore considered to have practically negligible mass in comparison to a proton or neutron, and its matter is not taken into consideration when calculating an atom's mass number.

The temperature of a sample of liquid water changes from 50°C to 30°C. Which statement best explains the change
KiRa [710]

Answer:

The molecules move slower than the temp of 50°c and their average kinetic energy decreases.

Explanation:

kinetic energy cannot increase as temperature is reduced. molecules will still move with reduced motion.

Give the name of the following molecule
shutvik [7]

Answer:

\boxed{Heptene}

Explanation:

Double Bond => An Alkene molecule

So, the suffix will be "-ene"

7 Carbons => So, we'll use the prefix "Hept-"

Combining the suffix and prefix, we get:

=> Heptene
