Answer:</h3>
Ammeter
<h3>
Explanation:</h3>
- Lets ask ourselves the following questions
What is an Ammeter?
- An ammeter is a device that is used to measure electric current in a circuit.
How is it used ?
- To measure the electric current the ammeter is placed in series with the components of the circuit and the reading on the ammeter is taken.
What is electric current?
- Electric current is a measure of the flow of electrons in a given circuit per unit time. It is therefore, the measure of the rate of flow of electrons in a circuit.
Mass CoCl2 = 10.27 g
moles CoCl2 = 10.27 g/ 129.839 g/mol=0.07910
mass water = 17.40 - 10.27=7.13 g
moles water = 7.13 / 18.02 g/mol=0.396
0.396/ 0.07910=5
CoCl2 * 5 H2O
moles CaF2 = 85.8 g/ 78.0748 g/mol=1.10
moles Ca = 1.10
mass Ca = 1.10 x 40.078 g/mol=44.1 g
V = 44.1 / 1.55 =28.5 mL
Greetings!!
Because more than one substance was released (following a color change signifying a chemical reaction), the sample was indeed, a compound.
Answer:
OH⁻ is the Bronsted-Lowry base.
Explanation:
A Bronsted-Lowry base is a substance that accepts protons. In the chemical equation, OH⁻ accepts a proton from H₂PO₄⁻ to become H₂O. H₂PO₄⁻ would be a Bronsted-Lowry acid because it donates a proton to OH⁻ and becomes HPO₄²⁻.
Hope that helps.
