4 0

10g of CaCO3 is decomposed, 5.6g of residue is left and 4.4g of CO2 is escapes.

In general ,calcium carbonate decomposes on heating to form calcium oxide and carbon dioxide. Reaction takes place like CaCO3(s)Heat⟶CaO (s)+CO2(g).

Substance breaks down into smaller species is known as decomposition. The Decomposition of limestone to calcium oxide (quicklime) and carbon dioxide on heating. When heated above 840°C, calcium carbonate decomposes, releasing carbon dioxide gas and leaving behind calcium oxide a white solid.

A section of a genome is cut with three enzymes: A, B, and C. Cutting with A and B yields a 10-kb fragment. Cutting with B and C
jonny [76]

Answer:

8-kb

Explanation:

As you can see in the picture attached, the cutting sites are consecutively situated in the genome. For that reason, if the largest fragment results when A and B cut, and the cutting site of C is betwen A and B, then the fragment expected from a digest with A and C could be calculated as follows:

AC=AB-BC =10 kb- 2kb=8kb

What density-dependent growth limiting factors kept the human population relatively low prior to the advent of agriculture?
4vir4ik [10]

Answer:

Limited food supply and competition

Explanation:

Density dependent factors are those which in general lead to reduction of growth rate of population when the population density increases. One of such factor is availability of food and competition.

Whenever the density increased to an extent where the resources or available food becomes scarce or limited,then the growth rate of population decrease.  These factors generally lead to logistic growth pattern of population.
