Answer:
1812g
Explanation:
So molarity is moles/litres or M= mol/liter (lets apply this formula to find moles)
M=mol/L
1.99=mol/2.66
Moles= 5.2934 moles of C12H22O11
Next step is quite simple, we know molar mass of C12H22O11 is 342.3 g/mol so we simply multiply the moles we get to molar mass we are left with the grams needed,
5.2934 moles of C12H22O11 * 342.3 g C12H22O11 /mol = 1812g
(I have left out decimal places, you can caculate this and add them if you desire)
Answer:
D
Explanation:
it's D because it goes waxing crescent to waxing gibbous
⇒Answer:
When the pH sensor hits pH=7.
⇒Explanation:
Because pH=7 is the indicator that the acid and alkali have been neutralized.
<h3><u>Answer;</u></h3>
D. All the above
- Covalent compounds are always poor conductors of electricity while ionic compounds conduct electricity well when melted or dissolved.
- Covalent compounds can be solid, liquid or gas, but ionic compounds are solids.
- In covalent compounds the elements present are usually close together on the periodic table whereas in ionic compounds they are usually well separated.
<h3><u>Explanation;</u></h3>
- <u>Ionic compounds are compounds that are formed from strong electrostatic interactions between ions.</u> Ionic bonding occurs between a nonmetal, which acts as an electron acceptor, and a metal, which acts as an electron donor. The atoms involved in ionic bonding lose or gain electrons and form positively or negatively charged ions.
- <em><u>Ionic compound are good conductors of electricity both in molten and aqueous form,. while covalent compound are poor conductors of electricity.</u></em>
- <u>Covalent compounds on the other hand are compounds that have bonds where electrons are shared between atoms.</u> These types bonds mostly occur between nonmetals or between two atoms of the same element.
