1. How much heat is gained by nickel when 29.2 g of nickel is warmed from 18.3°C to 69.6°C? The specific heat of nickel is 0.443 J/(g · °C

THE HEAT REQUIRED TO RAISE 29.2 G OF NICKEL BY 51.3 °C IS 663.60 J

Explanation:

Mass of nickel = 29.2 g

Temperature change = 69.6 °C -  18.3°C = 51.3 °C

Specific heat of nickel = 0.443 J/g °C

Heat = unknown

The heat of reaction of nickel is the amount of heat needed to raide a unit mass of nickel by 1 °C

Mathematically.

heat = mass * specific heat * change in temperature

Heat = m C ΔT

Heat = 29.2 * 0.443 * 51.3

Heat = 663.596 J

The heat needed to raise 29.2 g of nickel by 51.3 °C is approximately 663.60 J

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.

its first and third is your answer i did the qustion the fourth isnt right
