Answer:
Explanation:
an atom consists of prontons electrons and neutrons.
The nucleus is positively charged proven by the Rutherford experiment. The protons and neutrons are in the nucleus so the charges cancel out. The electrons are surrounded in the shells that are negatively charged.
The correct answer would be the second option. When the gibbs free energy of a system is negative and the electromotive force (EMF) of the system is positive then the reaction is to occur readily without any input of energy. With this, the reaction is said to be spontaneous. The higher the value of the EMF of a cell then it means the driving force for the reaction to occur is also high.
Answer:
The hotness or pungency of chilli is due to presence of a group of compounds called capsaicinoids. Among capsaicinoids, capsaicin and dihydrocapsaicin are present in major quantities, while homocapsaicin, nordihydrocapsaicin and homo-dihydrocapsaicin are present in very small quantities.
It's C, you're right.
Explanation:
A beta decay has the electron nuclei.
