Answer:
See detailed reaction equations below
Explanation:
a) Mg(s) +2HBr(aq) ----------------> MgBr2(aq) + H2(g)
b) Ca(ClO3)2(s) ------------> CaCl2(s) + 3O2(g)
c) 3BaBr2(s) +2Na3PO4(aq) ------------> Ba3(PO4)2(s) + 6NaBr(aq)
d) 3AgNO3(aq) + AlI3(aq) --------------> 3AgI(s) + Al(NO3)3(aq)
Balancing reaction equations involves taking valencies and number of atoms of each element on the reactants and products side into consideration respectively.
B An enclosed pendulum is not acted on by air resistence or gravity. Plus, pendulum's in clocks are electronic (I think) so that's why it keeps moving back in forth. (at least i think so)
Answer:
is that chromium on that computer ?
Explanation:
Answer:
Potential Energy is stored energy or energy of position (gravitational). The object isn't moving. For example, a ball being held is potential energy because the object isn't moving but it has the potential of turning into kinetic energy.
Kinetic Energy is the energy of motion. For example, running. You are moving, and there is clear action and activity
Answer: True
Explanation: 1 mole is proportional to the atomic mass of the respective atom (this case carbon) in grams. 12.011
moles = grams
1 mole of carbon = 12.011
i hope you understand bruh
