Answer:
a. Ca(s) + N₂(g) + 3O₂(g) → Ca(NO₃)₂(s).
b. C(s,graphite) + 2H₂(g) + 1/2O₂(g) → CH₃OH(l).
c. 3NaCl(s) + 4O₃(g) → 3NaClO₄(s).
Explanation:
<em>a. The formation reaction of Ca(NO₃)₂(s) is:</em>
Ca(s) + N₂(g) + 3O₂(g) → Ca(NO₃)₂(s).
- 1.0 mole of solid Ca reacts with 1.0 mole of N₂ gas and 3.0 moles of O₂ gas to produce 1.0 mole of solid Ca(NO₃)₂.
<em>b. The formation reaction of CH₃OH(l) is:</em>
C(s,graphite) + 2H₂(g) + 1/2O₂(g) → CH₃OH(l).
- 1.0 mole of solid C (graphite) reacts with 2.0 mole of H₂ gas and 0.5 mole of O₂ gas to produce 1.0 mole of liquid CH₃OH.
<em>c. The formation reaction of NaClO₄(s) is:</em>
3NaCl(s) + 4O₃(g) → 3NaClO₄(s).
- 3.0 moles of solid NaCl react with 4.0 moles of O₂ gas to produce 3.0 moles of solid NaClO₄.
True for example the law of conservation of matter
Answer:
SN2 mechanism
Explanation:
This is a situation were substitution occurs with inversion of configuration at the chiral centers which proceed through concerted backside attack where nucleophile approaches the alkyl halides 180° from c-br bond, as c-(nucleophile) bond forms , the c -(leaving group) bond breaks.
Answer: A. Sodium
Explanation: the most reactive element is sodium
A neutral particle of an atom is located at the nucleus.
<h3>What are electron cloud?</h3>
Electrons are those negatively charged particles that are found revolving round an atom.
Electron cloud is defined as the model of an atom in which the atom consists of a small but massive nucleus surrounded by a cloud of rapidly moving electrons.
A neutral particle is a nucleus because the nucleus of an atom is made up of neutral particles found within the nucleus of an atom which doesn't contain any charges.
An atom is defined as the smallest and indivisible part of an element which can take part in a chemical reaction.
An atom is made up of nucleus which consists of the proton (which is positively charged) and the neutron (which bears no charges at all).
Therefore, a neutral particle can be said to be an electron cloud.
