Answer:
its the same thing as 3 x3 or 3+3 it always come´s back as 9 or 6 Because of life
Explanation:
In a chemical equation, the symbol that means “dissolved in water” is (aq).
Answer:
True
Explanation:
The majority of the reactions happened with a flow of heat. When there's no heat, the reaction is adiabatic.
For no adiabatic reactions, the heat can be released (evolution) by the system, so the reaction will be exothermic, or absorbed by the system (absorption), then the reaction is called endothermic.
Answer:
A FUSE is a type of conductor which protects the circuit by shorting it down when there is excess flow of current passing through it.
Explanation:
A fuse wire is made up of conducting materials such as alloy of tin and lead that has high resistivity. It has a low melting point of 200°C. It works based on the principle of heating effect of electric current. The functions of fuses include the following:
--> Fuses are made up of thin wire CONDUCTORS which interrupts or breaks the current flow of a circuit when in excess, thereby protecting the circuit from damage.
--> it prevents overload of current. In the event where too many appliances are connected to a single circuit, this can lead to overload which triggers a fuse to terminate the circuit connection.
--> It prevents total black-out: SWITCH-LIKE devices known as CIRCUIT BREAKERS share this function with the fuses. The nearest circuit breaks if any dysfunction occurs in the components of the circuit thereby preventing blackout.
Answer:
The correct answer is 16.6 mL
Explanation:
The density of a substance is defined as its mass per unit of volume. Thus:
density = mass/volume
So, to calculate volume: volume = mass/density
Given:
density= 10.5 g/cm³
mass= 5.25 g
We calculate the volume occupied by silver as follows:
volume= mass/density= (5.25 g)/(10.5 g/cm³)= 0.5 cm³
Moreover, we know that 1 cm³= 1 ml. So, a mass of 5.25 g of pure silver occupies a volume of 0.5 ml. If we add the mass of silver to a graduated cylinder with 16.1 mL of water, the final volume will be given by the initial volume of water plus the volume occupied by silver:
volume level = 16.1 mL + 0.5 mL = 16.6 mL
