Answer:
The nucleus is a collection of particles called protons, which are positively charged, and neutrons, which are electrically neutral. Protons and neutrons are in turn made up of particles called quarks. The chemical element of an atom is determined by the number of protons, or the atomic number, Z, of the nucleus.
<span>Changing atmospheric conditions, like increasing carbon dioxide content, might possibly increase the risk of global warming. Carbon dioxide, along with other greenhouse gases, is one of the leading causes of our Earth's rise in temperature. This is because greenhouse gases trap the planet's heat inside its atmosphere, preventing it from leaving the Earth's surface. </span>
Answer : The volume (in mL) of 95% ethanol added would be, 1.39
Explanation :
As we are given that:
Mass of 95 % ethanol = 1.2 g
Density of 95 % ethanol = 0.86 g/mL
Formula used :
Therefore, the volume (in mL) of 95% ethanol added would be, 1.39
