Answer:
false
Explanation:
Atoms of the same element that differ in their numbers of neutrons are called isotopes. Many isotopes occur naturally. ... Different isotopes of an element generally have the same physical and chemical properties because they have the same numbers of protons and elec
13 An Ionic Bond
these are the characteristics of an ionic bond compounds like NaCl have these characteristics
14 substances could be compounds or elements hence not all substances are compounds
15 It is not water. The chemical composition of water is H2O not H202
(H202 is hydrogen peroxide and is toxic)
Answer:
increase the rate of a reaction without being consumed by the reaction
Explanation:
- Enzymes are biochemical catalysts that increase the rate of chemical reactions.
- They increase the rate of a chemical reaction without being consumed by the reaction.
- Enzymes increase the rate of chemical reactions by decreasing the activation energy of the reactants.
- Catalysts such as enzymes do not affect the free energy change of a chemical reaction (delta G). Therefore, delta G for a catalyzed and non-catalyzed reaction is equal.
Answer:
B. 1.82(10³) seconds (1820 seconds)
Explanation:
Speed of Light: 3.00(10⁸) m/s or 3.00(10⁵) km/s
We know the distance from the Moon to Earth as 5.46(10⁸) km
We simply divide the distance by the speed of light:
We should get 1820 seconds or B. 1.82(10³) as our answer.
The answer is A.4m/s because a bowling ball has more mass then a basketball
I hope this helps
