Chemistry
1 answer:
saul85 [17]3 years ago
3 0

Answer:

pH = 2.0

Explanation:

To find the pH of a solution, take the -log[H+]. In this case, the -log(9.4 x 10^-3) equals 2.02687 which makes 2.0 when accounting for significant figures.

Elis [28]

Hi! Glucose and oxygen are required for cellular respiration. As the law of conversation states, in a biochemical reaction, mass is conserved. For every glucose molecule, 6 oxygen molecules are used up and the end products, other than the energy dissipated by the reaction, are 6 water molecules and 6 carbon dioxide molecules. Brainliest?

Calculate the mass of 1.23×1024 helium atoms.
just olya [345]

6.023*1023 He atoms=1 mole He

1.23×1024 helium atoms=1.23×1024/6.023*1023 =2.042 mole He

one mole He=4.0 gm

2.042 mole He=2.042*4.0=8.168 gm

answer in grams of Helium is 8.168 gm

Lewis dot structure of PSI3 with minimized formal charges
vredina [299]

We need to know how many valence electrons are present in a given molecule in order to determine its Lewis dot structure.

<h3>What is Lewis dot structure?</h3>

Lewis dot structure is defined as the visual representation of atoms' electrons using a diagram. It describe the bonds that exist between a molecule's lone pairs of electrons and its atoms.

A lone pair of electrons on the atom with the formal charge of 1- can typically be converted into a bonding pair that is shared with the atom that has the formal charge of 1+ in order to reduce the formal charges when they are present.

Thus, we need to know how many valence electrons are present in a given molecule in order to determine its Lewis dot structure.

To learn more about Lewis dot structure, refer to the link below:
