Answer:
An electric circuit is an unbroken path along which an electric current exists and/or is able to flow. ... Once one of the wires is removed from the power source or a “break” is made in the flow, the circuit is now “open” and the lamp will no longer light.
Explanation:
Answer:
0.4402 grams of Mg is needed to displace all of the copper (II) ions from the solution.
Explanation:
Moles of CuO =
1 mole of CuO has 1 mole of ions, then 0.01834 molesof CuO will have 0.01834 moles of
According to reaction , 1 mole of copper (II) ion reacts with 1 mole of magnesium solid .
Then 0.01834 moles of copper (II) ion will react with :
of magnesium.
Mass of 0.01834 moles of magnesium :
0.01834 mol × 24 g/mol = 0.4402 g
0.4402 grams of Mg is needed to displace all of the copper (II) ions from the solution.
Answer:
Light energy in photosynthesis
Explanation:
In the photosynthetic process, light energy absorbed by chlorophyll b is transferred to chlorophyll a. ... This molecule is known as the energy trapping centre (trap) or reaction centre, as it is here that the light energy is converted into chemical energy.
Planets revolve around the sun because of gravity. When the planets were made, the sun's gravity was strong enough so that the planets continued to stay around the sun and orbit.
1,3-butadiene is the simplest conjugated diene and undergoes 1,4 addition reaction in acidic environment.
Chemical reaction: CH₂=CH-CH=CH₂ + H₂O → CH₃-CH=CH-CH₂-OH.
CH₂=CH-CH=CH₂ - 1,3-butadiene.
CH₃-CH=CH-CH₂-OH - 2-buten-1-ol.
