Endothermic reactions absorb heat and exothermic reactions give off heat
Answer:
Density, 
Explanation:
Given that,
Mass of marble slab is 38.6 kg or 38600 g
The dimensions of the slab is 23 cm × 17 cm ×4 cm
We know that the density of an object is given in terms of its mass volume as follows :
So, the density of the marble slab is 
False. It can’t because a glaciers weight combined with its gradual movement can drastically reshape the landscape over hundreds and even thousands of years.
A renewable resources are resources that will not run out
Chemical leavening agents are baking soda and a mixture of baking powder. It reacts immediately when added to liquids because it causes two separate reaction to occur in the dough. The first reaction happens when the baking powder is mixed with liquids; it causes carbon dioxide to be produced. The second reaction occurs when the heat mixed during the baking process; causes further expansions.
