Answer:
convection could be a pot on a stove, radiation could be the sun and heat waves, and conduction could be a cup with coffee.
Explanation:
Conduction occurs when two objects are in direct contact with each other.
Convection is the transfer of heat through liquids and gases. Convection occurs above a hot surface because hot air expands and rises and is replaced by cooler, denser air.
Radiate energy is given off by a hot object and directly absorbed by another cooler object. This cause the cooler object to get warmer. Radiation can occur even if no air is present.
Answer:
To find the mass percent of hydrogen in hydrogen chloride, we must divide the weight of the hydrogen atom alone by the weight of the entire molecule. Then we multiply by 100% to find the percentage. Thus, 2.77% of the mass of hydrogen chloride is hydrogen.
Explanation:
i hope you understand better
We find out the molar mass of NH₃.
atomic mass (N)=14 u
atomic mass (H)=1 u
atomic weight (NH₃)=14 u + 3(1u)=17 u
Therefore the molar mass of NH₃ will be: 17 g/mol
Then:
1 mol of water=18 g
2) We know that:
1 mol of any substance=6.022 * 10²³ particles.
3)We calculate the mass of 8.00 *10²² molecules
18 g of water----------------------------6.022*10²³ molecules
x---------------------------------------------8.00*10²² molecules
x=(18 g of water * 8.00*10²² molecules) / 6.022 * 10²³ molecules=2.39 g
Answer: the mass of 8.00 *10²² molecules of NH₃ would be 2.39 g.
