Can fungi move around in its environment

A potassium bromide solution is 7.55% potassium bromide by mass and its density is 1.03 g/ml. part a what mass of potassium bromide is contained in 35.8 ml of the solution?

If you have 7 boxes to be moved, the same amount of work is done whether 5 men do the work or 1 person does it. TrueFalse

Ammonia is a weak base. if the initial concentration of ammonia is 0.150 m and the equilibrium concentration of hydroxide is 0.0016m, calculate kb for ammonia.

Determine which change of state is being described in this passage. As the temperature decreases, the atoms lose energy. The atoms begin to move slower. They are held together by attractive forces, but are still able to slide past each other.

When the amount of energy required to break bonds in the reactants is less than the amount of energy released in forming bonds in the products, the process has a negative change in enthalpy (-ΔH). True False
