Explanation:
Answer: 
millimoles will be left after 2255 years.
Explanation:
Expression for rate law for first order kinetics is given by:
where,
k = rate constant
t = age of sample
a = let initial amount of the reactant
a - x = amount left after decay process
a) 
of carbon = 5730 years
b) millimoles left after 2255 years
Answer:
2moles of H2 will react with 1mole of O2 to form 1 mole of water
If H2 is 14.9
O2 will be 14.9×2=29.8
Answer:
Radiation
Conduction
Convection
Explanation:
<u>Radiation:</u> Transfer of heat by electromagnetic rays (Example: A microwave heating food)
<u>Conduction:</u> Transfer of heat energy from one object to another through direct contact (Example: Getting out of bed and your warm feet touch cold tile, making the tile warm and your feet cold)
<u>Convection:</u> Movement of heat by a fluid such as air or water (Example: A convectional oven works by heating the air inside the oven to evenly cook food)
Hope this helps!
Answer:
B, C, E, G
Explanation:
B - As particles are heated, they gain heat energy (or thermal energy, Q) from whatever the source may be.
C - Thermal energy particles gain is converted into kinetic, and the more KE/kinetic energy particles have, the more energy they have to move around.
E - When particles have more energy to move around more, they slide and move past each other and create more space; hence, they become further apart.
G - Eventually, particles will have enough energy and will move around so much that the attracting forces holding them together in the first place will be lesser than the particle's energy to break free and move from the attractive forces.
