The independent variable would be the type of liquid the dependen is the evaporation rates
Electromagnet is a type of magnet which is produced by passing electric current through a magnetic material such as iron. Here electric energy is converted to magnetic energy. The magnetic material is coiled with wire through which electric current is passed. Increasing the number of coils and increasing the strength of the current increases the strength of the electromagnet. However, the electromagnet loses its magnetic properties when the current flow is switched off.
(Answer) (1) Increase the number of coils and increase the strength of the current.
Answer:
C
Explanation:
C is the right answer because it does make sense and its true that if you expose different types of leaves at low temperatures, they WILL change colors :)

Answer:
0.570 L
Explanation:
Given:
Concentration of the HCl solution = 0.750 M
Mass of NaCl in the reaction = 25.0
Number of moles of NaCl in the reaction = Mass of NaCl / Molar mass of NaCl
also,
Molar mass of NaCl = 22.98 + 35.45 = 58.43 grams
thus,
Number of moles of NaCl in the reaction = 25 / 58.43 = 0.4278 moles
now,
1 mol of NaCl reacts to form 1 mol of HCl
thus,
0.4278 moles of NaCl reacts to form 0.4278 mol of HCl
also,
Concentration = Moles / volume of solution
0.750 = 0.4278 / volume of solution
or
volume of solution = 0.570 L
a. double replacement
b. AB + CD ⇒ AD +CB
c and d
H₃PO₄ : Phosphoric acid
KOH : Potassium hydroxide
K₃PO₄ : Tripotassium phosphate
H₂O : water
<h3>Further explanation</h3>
Given
Reaction

Required
Type of reaction
General equation
Name of reactants and product
Solution
Double replacement reaction : Cations and anions of different compounds switch places
It can also be said as <em>a neutralization reaction</em> because it produces water(reaction between an acid and a base)
AB + CD ⇒ AD +CB
- Name of reactants and products
