Which statements best describe a composite material? Select all correct answers. A composite may have more desirable properties than its components.

Composites all contain carbon, which makes them lightweight.

Composites form hydrogen bonds, which makes them stronger than their components.

A brick made of mud and straw is an example of a composite; a brick made of mud is not.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

wher is the rest of the question

a is the correct answer

rosa was looking for patterns to predict the products of chemical reactions. she recorded three similar decomposition reactions in the table.she should record 2licl + 3o2.

in the last row of the table. it is the thermal decomposition of chlorate lithium, hence, she should record these products as: lithium chloride ( 2licl ) and oxygen ( 3o2 )   2 > 2 licl + 3o2.
