#8 would be radiation
Because of the heat it produces for the air in the home
#9 Conduction
Because it’s preventing physical heat transfer
#10 convection
Because it is stopping the air from rising
#11 Radiation
Because the heat is emitting from the stove and warms him, but not by direct contact
#12 Conduction
Because the heat transfers from the top of the stove to the cats fur.
#13 Conduction
Because the stove under it heats it through contact
#14 I think Radiation
Because the heat warms up the dish through the air in the oven
#15 Radiation
Because the heat is emitting from the fire.
#16 Conduction
Because the blanket is warming you through physical contact.
I’m not completely sure but the is the best I got. Good luck!
The gram-formula mass of Sm is 150.36 u, and the gram-formula mass of O is 15.999 u, so the gram-formula mass of SmO is about 150.36+15.999 = 160.36 g/mol.
So, there are about (9.30 * 10^-3)(160.36)=1.49 grams
Answer:
B)
Explanation:
It is the theme of the passage.
Answer:
Carbon iv oxide + water - - carbonic acid
Explanation:
CO2 + H2O--H2CO3 (balanced equation)
Answer:
Explanation:
1) NaCl → Na + Cl₂
2) Na + HCl → NaCl + H₂
Chemical equation:
NaCl → Na + Cl₂
Balanced chemical equation:
2NaCl → 2Na + Cl₂
There are two moles of sodium and two mole of chlorine on both side of equation so given chemical equation is correctly balanced and follow the law of conservation of mass.
2)
Chemical equation:
Na + HCl → NaCl + H₂
Balanced chemical equation:
2Na + 2HCl → 2NaCl + H₂
There are two moles of sodium and two mole of chlorine and hydrogen on both side of equation so given chemical equation is correctly balanced and follow the law of conservation of mass.
Law of conservation mass
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
Explanation:
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction.
