Answer:
89.6 liters
Explanation:
A STP (standard temperature and pressure) ONE mole of any idea gas will occupies 22.4 liters. So,...
4 moles x 22.4 L/mol = 89.6 liters
Answer:
They are all located in the same horizontal row or period.
Explanation:
In the periodic table the elements are arranged according to their increasing atomic number.The elements those contain low atomic number are placed in the first row such as hydrogen and helium. similarly the radioactive elements those have high atomic number are placed in 7th or 8th row.
All the elements of a family in the peroidic table have common features are located in same horizontal row or period.For example fluorine,chlorine,bromine and iodine are placed in VII B class of periodic table as all of them are electronegative in nature.
D. A force that acts between charged and uncharged particles. I think it’s D because the electrostatic force is the attractive or repulsive force between two electrically charged objects. D is the closest answer to the definition of electrostatic force
2. D) A solution that has more solute in it than it can hold is called a supersaturated solution. An easy way to know this is because super means that there is more.
3. I'm not sure about this one, but all I can tell you is that the gram formula mass of H2SO4 is 98 grams.
4. D) C2H6SO is the empirical formula. We know this because all of the subscripts are simplified as much as possible. You might try to simplify the C2 and H6 but take note that the S and O have no subscripts, so elements cannot be simplified anymore.
5. D) ethanoic acid (C2H4O2) has the same empirical formula as glucose. The empirical formula of glucose is CH2O. This is because the subscripts of 6/12/6 have a common factor of 6, so we divide them all by 6 to get subscripts of 1/2/1. Ethanoic acid has subscripts of 2/4/2. They have a common factor of 2, so when we divide them by 2, they will become 1/2/1.
Answer:
Photodisintegration!
Explanation:
also called Phototransmutation, in physics, nuclear reaction in which the absorption of high-energy electromagnetic radiation (a gamma-ray photon) causes the absorbing nucleus to change to another species by ejecting a subatomic particle, such as a proton, neutron, or alpha particle.
