Answer:
9.15×10²³molecules
Explanation:
moles=number of particles/Avogadro's number
1.52=x/6.02×10²³
by cross multiplication;
x=1.52×6.02×10²³
=9.15×10²³

Answer:
The answer to this question is; <em>1.08 x 10^5</em>
Explanation:
This is the correct option because
600 x 180 = 108,000
108,000. -> move the decimal over 5 times to get a number between 1 and 10
1.08 x 10^5
Answer:
Your stomach lining also secretes hydrochloric acid, which creates the ideal conditions for the protein-digesting enzymes to work. The potent hydrochloric acid kills bacteria, protecting your body from harmful microbes which can enter your body in food.
The spontaneity of a reaction can be predicted by the amount of Gibbs free energy. If it is negative, then the reaction is spontaneous. The reaction for Gibb's energy is
ΔG=ΔH-TΔS, where H is the enthalpy, T is the temperature and S is the entropy.
If the reaction favors low temperature, the enthalpy must be negative so that it will yield a negative ΔG. In other words, an exothermic reaction is spontaneous even at low temperatures. Also, the reaction could still be spontaneous if entropy is high, meaning, the system is not in order.
<u>Answer:</u> The chemical formula of the given compound will be 
<u>Explanation:</u>
The compound formed is disulfur dioxide.
Covalent compound is defined as the compound which is formed by the sharing of electrons between the atoms forming a compound. These are usually formed when two non-metals react.
Disulfur dioxide is a covalent compound because sharing of electrons takes place between sulfur and oxygen. Both the elements are non-metals and hence, will form covalent bond.
The nomenclature of covalent compound is given by:
- The less electronegative element is written first.
- The more electronegative element is written then, and a suffix is added with it. The suffix added is '-ide'.
- If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on..
Hence, the chemical formula of the given compound will be
