It makes the concentration of protons higher outside of the membrane than the inside
Answer:
(1) 4- ethyl -6 methyl -2 octyne
Answer:
quartz
Explanation:
<em>The correct option would be </em><em>quartz.</em>
<u>Allotropy is a phenomenon that describes the natural existence of the same element in different forms with different physical characteristics. Allotropes are therefore different forms of the same element.</u>
Carbon as an element has several allotropes which include diamond, graphite, graphene, amorphous carbon, and fullerenes. Quartz is a crystalline solid that is composed of silicon dioxide and not carbon.
Hence, all the options are carbon allotropes except quartz.
Answer:There is a difference between the meanings of the chemistry terms atomic mass and mass number. One is the average weight of an element and the other is the total number of nucleons in the atom's nucleus. ... The mass number is a count of the total number of protons and neutrons in an atom's nucleus
Explanation:
<h3>Answer:</h3>
Molarity = 0.1516 mol.L⁻¹
<h3>Solution:</h3>
<em>Molarity </em>is the amount of solute dissolved per unit volume of solution. It is expressed as,
Molarity = Moles / Volume of Solution ----- (1)
Data Given;
Mass = 8.45 g
Volume = 0.750 L
Step 1: Calculate Moles for given mass as,
Moles = Mass / M.mass
Moles = 8.45 g / 74.55 g.mol⁻¹
Moles = 0.1133 mol
Step 2: Calculating Molarity:
Now, putting value of Moles and Volume in eq. 1,
Molarity = 0.1133 mol ÷ 0.750 L
Molarity = 0.1516 mol.L⁻¹
