Answer:
energy
Explanation:
The amount of energy carried by a wave is related to the amplitude in waves.
Answer:
359 grams FeO
Explanation:
To find how many grams FeO are produced, you need to use the moles of Fe, convert it to moles of FeO (using the mole-to-mole ratio from the equation), then convert the moles of FeO to grams (using the molar mass from the periodic table).
2 Fe + O₂ --> 2 FeO
Molar Mass (FeO) = 55.845 g/mol + 16.00 g/mol
Molar Mass (FeO) = 71.845 g/mol
5.00 moles Fe 2 moles FeO 71.845 grams
---------------------- x ------------------------ x ---------------------- = 359 grams FeO
2 moles Fe 1 mole FeO
Answer:
contain hereditary information
break down food into energy
Explanation:
Hereditary information is contained in genes and genes are found inside the cell. This implies that the cell contains hereditary information of organisms. This hereditary information is passed on during cell division from parent to daughter cells.
Metabolism occurs in the cells. The cells use oxygen to break down food materials to produce energy.
Answer:
Sodium chloride is an ionic compound which makes it stronger and have a higher melting and boiling point. Candle wax is a covalent compound so it has a low melting point.

You know if it's endothermic or exothermic by doing the enthalpy reaction. If the change of temperature is negative then it is exothermic, while positive is endothermic.
If you get -22K then its exothermic, but if you get +22 its endothermic.
