What is the word and symbol equation for the reduction reaction between magnesium oxide and carbon?
This reaction is:MgO + C = Mg + CO2MgO + C -> 2Mg +CO2
A neutralization reaction was carried out in a calorimeter The temperature of the solution rose from 20.0 C to 25.6 C Is this reaction endothermic or exothermic?
Exothermic
Is the Calvin-Benson cycle the same thing as Cā cycle?
It is called C 3 pathway , or dark reaction or light independent reaction .
What is is a define single-replacement reaction.?
A single replacement reaction involve the replacement of an element with other in the molecule as in this model:A + B-C = A-C + B.
Why do changes in temperature often happen during chemical change?
This is due to changes in energy. Look at the chemical reaction A + B --> C . Say it requires a lot of energy for A and B to react together, but very little energy to keep C as C. All the energy you put into the reaction to make A and B turn into C will be released as heat once C is formed. However if it requires a lot of energy to keep C as C after the reaction happens, then the reaction will seem cold because it is taking energy in the form of heat out of its surroundings!
Which equation represents a transmutation reaction?
14/6 C --> 14/7 N + 0/-1e
What is the type of nuclear reaction that caused the amount of C-14 in a woolly mammoth to decrease after the organism died?
The type of reaction is transmutation .(thanks for reading it )
An excited atom can lose energy by?
*Capturing an orbiting electron *Emitting a positron So C both of the above
What type of radiation is given off in the nuclear reaction 14 6 C 14 7 N plus?
A single electron is emitted from the carbon atom. This is usually called beta radiation.
What is the word and symbol equation for the reduction reaction between magnesium oxide and carbon?
This reaction is:MgO + C = Mg + CO2MgO + C -> 2Mg +CO2
The reaction that occurs when the products of the light reaction are used to form C-C covalent bonds of carbohydrates?
dark!
Why you need 1.022 Mev in pair?
Pair production can only occur if the energy of the photon is bigger than the rest mass (E0 = m0*c^2) of electron and positron, because this is the energy needed to create these particle (conservation of energy). Excess energy will be kinetic energy of the electron and positron. Rest mass of electron and positron is 0.511 MeV each, so 1.022 MeV in total.

Dark
What does 3 plus c equals -14 eauals?
-11
Why does the C 14 C 12 ratio change with time in fossils?
An organism stops taking in carbon when it dies.
A neutralization reaction was carried out in a calorimeter The temperature of the solution rose from 20.0 C to 25.6 C Is this reaction endothermic or exothermic?
Exothermic
What is C in the equation -14 plus c plus 6 equals -5?
-14 + c + 6 = -5-14 + c = -5 minus 6-14 + c = -11c = -11 minus -14c = -11 plus 14c = 3
