Is there any difference between carbon(iv)oxide and carbon(ii)oxide

Answers

Answer 1

Answer: The difference is the no. of charges present in Carbon, meaning Carbon has different charges therefore Roman numerals are used to clarify the exact number.This makes balancing equations easier.

Also their names are different.
CO4 - Carbon tetroxide
CO2 - Carbon dioxide

If atoms are made of smaller parts such as electrons, why are atoms considered the basic unit of matter?

Answers

Atoms are considered the basic unit of matter because it is atoms that make up the elements which in turn combine to form compounds that exist in all states. It is true that atoms are made up of electrons and neutrons and protons, but they are not useful on their own individual level. Like, you don't hear anyone say that "the particles that make up atoms are the basic unit of matter".

Explanation:

Atoms are considered as the basic unit of matter because atoms combine to form matter. Atoms combine to form elements and compounds which further make up the atom.

Atoms contain electron, proton and neutrons. Electrons are negatively charged particles. They do not combine to form matter. A stable atom is a combination of fixed number of electrons, protons and neutrons.

Although wave power does not produce pollution, some people may not want to invest in it because it is _____.

Answers

Answer:

Prone to storm damage and limited to particular areas of the ocean

Explanation:

Hello,

Even when the wave power is beneficent towards the environment care, it has a notable disadvantage when high energy waves are took by the energy stations by cause of electrical failures which lead to the station breakdown. On the other hand, there are hard-to-access areas in the ocean which restricts the enforcement of this type of energy.

Best regards.

The correct answer for the question that is being presented above is this one: "Although wave power does not produce pollution, some people may not want to invest in it because it harms marine life and its difficult to mountain it also disturbs the route of the ships."

In which sample is the average kinetic energy of the particles greatest?(1) 10. mL of HCl(aq) at 25°C
(2) 15 mL of HCl(aq) at 20.°C
(3) 10. mL of H2O(l) at 35°C
(4) 15 mL of H2O(l) at 30.°C

Answers

Answer: The correct answer is option 3.

Explanation: Average kinetic energy is defined as the energy of motion of the particles of a system. It is a measure of Kelvin Temperature.

Mathematically,

$K=(3)/(2)(R)/(N_A)T$

where,

K = kinetic energy of the molecules measured in joules.

R = Gas constant = $8.314Jmol^(-1)K^(-1)$

$N_A$ = Avogadro's number = $6.022* 10^(23)atoms/mol$

T = Temperature in kelvins.

Kinetic energy is directly proportional to the temperature of the system.

$\text{Kinetic energy}\propto \text{Temperature}$

More the temperature, more will be the kinetic energy of the molecules.

Hence, the correct answer is Option 3.

The question asks about the average kinetic energy, so it is related only to temperature. Then the answer is (3) with the highest temperature.

What is the definition of a Lewis acid?a substance that accepts electrons to form a covalent bond
a substance that donates electrons to form a covalent bond
a substance that accepts a proton
a substance that donates a proton

Answers

Lewis acid is:

A. a substance that accepts electrons to form a covalent bond

What is a Lewis acid?

A Lewis acid is accordingly any substance, for example, the H+ particle, that can acknowledge a couple of nonbonding electrons. At the end of the day, a Lewis acid is an electron-pair acceptor.

Thus, option A is correct.

What weighs more? 1 mol of Gold, or 1 mol of Lead. A. You cannot determine the answer to this question from this information alone B. They both weigh the exact same amount C. 1 mol of Gold D. 1 mol of Lead

Answers

b, they both weigh the exact same. they’re both 1 mol

Final answer:

1 mol of Lead weighs more than 1 mol of Gold because lead has a higher atomic mass (207.2 g/mol) compared to gold's atomic mass (197.0 g/mol). Option D. is correct.

Explanation:

Consider the atomic masses of both gold and lead, as the question involves comparing a mole of each. Importantly, the molar mass of any substance is numerically equivalent to its atomic weight in Atomic Mass Units (amu). The atomic mass of gold is approximately 197.0 amu while lead has an atomic mass of around 207.2 amu.

Therefore, a 1 mol of Lead (207.2 g) would weigh more than 1 mol of Gold (197.0 g).
