Answer:
The density remains the same
Explanation:
The density remains the same because cutting the object in half will divide the mass & volume by the same amount. The density cant be changed no matter what happens to it.
Answer:
![Ka=\frac{[H^+][HCOO^-]}{[HCOOH]}](https://tex.z-dn.net/?f=Ka%3D%5Cfrac%7B%5BH%5E%2B%5D%5BHCOO%5E-%5D%7D%7B%5BHCOOH%5D%7D)
Explanation:
Hello,
In this case, the weak ionization reaction for formic acid is:
In such a way, we simply recall the law of mass action in order to represent the weak ionization constant, Ka, for such process, by taking into account that the concentration of products is divided over the concentration of reactants as shown below:
Best regards.
C. Electrons fill orbitals in order of increasing orbital energy.
Answer: specie
Explanation:
A specie is the smallest group of organisms with similar characteristics and are capable of living with each other and breeding together freely. They give rise to young ones (offspring) that resembles the parents and can also breed with organisms of same species.
Examples of species include
- a group of lizards
- a group of human beings etc
Answer:
The answer to your question is 1.46 g of Cl₂
Explanation:
Data
mass of Cl₂ = ?
mass of NaCl = 2.4 g
Chemical reaction
2Na + Cl₂ ⇒ 2NaCl
Process
1.- Calculate the molar mass of chlorine and sodium chloride
Molar mass Cl₂ = 2 x 35.5 = 71 g
Molar mass of NaCl = 23 + 35.5 = 58.5 g
2.- Use proportions to solve this problem
71g of Cl₂ --------------------- 2(58.5g) NaCl
x --------------------- 2.4 g
x = (2.4 x 71) / 2(58.5)
x = 170.4 / 117
x = 1.46 g of Cl
