NemiM [27]3 years ago
5 0

Answer:

volume = 2128L

Explanation:

volume at stp = 22.4dm³ =22400L

CO2 = 12 + 2(16) = 44

4.20/44 = volume/22400L

0.095 = volume/22400L

volume = 0.095 x 22400

volume = 2128L

SCIENCE, PLEASE HELP.
sesenic [268]

Answer: B

Explanation:

protons are positive,

electrons are negative,

and neutrons are neutral.

the amount of electrons to protons is always the same in a balanced atom.

electrons can be removed creating "ions" which is simply an unbalanced atom. removing protons would result in a different type of atom or element.

Answer:

\rm ^{103}_{\phantom{1}40}Zr, zirconium-103.

Explanation:

In a nuclear reaction, both the mass number and atomic number will conserve.

Let ^{A}_{Z}\mathrm{X} represent the unknown particle.

The mass number of a particle is the number on the upper-left corner. The atomic number of a particle is the number on its lower-left corner under the mass number. For example, for the particle ^{A}_{Z}\mathrm{X}, A is the mass number while Z while Z is the atomic number.

Sum of mass numbers on the left-hand side of the equation:

\underbrace{239}_{^{239}_{\phantom{2}94}\mathrm{Pu}} + \underbrace{1}_{^{1}_{0}\mathrm{n}} = 240.

Note that there are three neutrons on the right-hand side of the equation. Sum of mass numbers on the right-hand side:

\underbrace{A}_{^{A}_{Z}\mathrm{X}} + \underbrace{134}_{^{134}_{\phantom{2}54}\mathrm{Xe}} + \underbrace{3\times 1}_{3\;^{1}_{0}\mathrm{n}} = A + 137.

Mass number conserves. As a result,

A + 137 = 240.

Solve this equation for A:

A = 103.

Among the five choices, the only particle with a mass number of 103 is \rm ^{103}_{\phantom{1}40}Zr. Make sure that atomic number also conserves.

Which statement about covalent compounds is FALSE?
Vladimir79 [104]

Answer: b . Covalent compounds can contain a maximum  of 4 different atoms.

Explanation:

The covalent compounds are those compounds that are formed between the non-metals via sharing of electrons. The bonds so formed between these non-metallic atoms are covalent. There can be two or several different kinds of atoms that can form covalent bonds with each other in a single molecule. They use the valence electrons for sharing. The maximum number of valence electrons can be seven.
