Answer:
When we weigh beans in this mass ratio, we must obtain the same number of beans.Explanation:
Nothing will happen
Answer: 0.66 g/mL
Explanation: The formula for density is d= m/v where m=mass and v=volume.
The mass was given in the problem, m= 1.32kg
The volume was also given in the problem, v= 2.0L
d= m/v ---> d= 1.32kg/2.0L ---> d=0.66kg/L
The problem calls for the answer to be written in g/mL, so we must convert the units. 1 kg contains 1000g and 1 L contains 1000 mL.
1000g/1000mL = 1 so the units change but the 0.66 does not. Therefore, your answer is 0.66g/mL (Two significant figures because 2.0 only has 2 significant figures).
T'belongs to the hydrides, it's a nitrogen hydride.
Answer:
The answer to your question is below
Explanation:
Ionic bond is a kind of bond in which a metal attaches to a nonmetal. Also we know that a molecule has ionic bonding if the electronegativity is higher than 1.7.
Kind of elements Difference of electronegativity Bond
a) MgO Metal - Nonmetal 3.44 - 1.31 = 2.13 Ionic
b) SrCl₂ Metal -Nonmetal 3.16 - 0.95 = 2.21 Ionic
c) O₃ Nonmetal- Nonmetal 3.44 - 3.44 = 0 Covalent
d) CH₄O Nonmetal-Nonmetal 3.44 - 2.55 = 0.89 Covalent
Carbon, Hydrogen and oxygen are nonmetals
2) Silver coins can conduct electricity.
