Answer:
The pH would be 1.
Explanation:
The pH of an acid can be found by using the formula pH = - log [H⁺]. This was a method developed to be able to measure the pH of substances.
Since the concentration of HNO₃ is 0.1 M, then it also means that the concentration of H⁺ ions is 0.1 M.
By substituting for the formula: pH of 0.1 M HNO₃ = - log [0.1]
= 1
Answer:
A. Lactate for muscular cells B. Ethanol for yeast
Explanation:
Lactate or lactic acid is produced for muscular cells in absence of oxygen. That is the reason because people fell pain in muscles after an physical activity. Ethanol is produced for yeast in absence of oxygen. The glycolysis goal is produce energy in ATP form. When oxygen is available, energy production is more efficient than oxygen is absence.

The answer to this question would most definitely be the last one
Gr terlarut = 36 gr
<span>Mr terlarut = 180 </span>
<span>gr pelarut = 250 gr </span>
<span>Kb air = 0,52 °C kg/mol </span>
<span>Tb larutan = ........? </span>
<span>--------------------------------------... </span>
<span>ΔTb = Kb.m.i </span>
<span>ΔTb = Kb. (gr t / Mr t) . (1000/ gr p) .i </span>
<span>ΔTb = 0,52 x (36/180) x (1000/250) x 1 </span>
<span>ΔTb = 0,416 °C </span>
<span>Tb = 100 + ΔTb </span>
<span>Tb = 100 + 0,416 </span>
<span>Tb = 100,416 °C</span>
Nonpolar covalent bonds are a type of chemical bond where 2 atoms share electrons with each other.
Polar covalent bonds are the same as nonpolar covalent bonds, but a pair of electrons are unequally shared between 2 atoms.
Ionic bonds are a type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound.
Hope this helps! ^-^
