Each different species of grass grows best in a particular grassland environment (determined by temperature, rainfall, and soil conditions). The seasonal drought, occasional fires, and grazing by large mammals all prevent woody shrubs and trees from invading and becoming established.

Explain the difference between naming a covalent compound and an ionic compound.
erica [24]

Answer: An ion with fewer electrons than its neutral atom is called a(n) cation. The charge of an ion with more electrons than its neutral atom is. negative.Name an ionic compound by the cation followed by the anion. ... Covalent compounds are formed when two or more nonmetal atoms bond by sharing valence electrons. Valence electrons are the outermost electrons of an atom.

750.0g of water that was just boiled (heated to 100.0/c loses 78.45KJ of heat as it cools.What is the final temperature of water
Iteru [2.4K]
  • Mass=m=750g=0.75kg
  • Q=78.45\times 10^3J=78450J
  • T_i=100°C
  • T_f=?
  • Specific heat capacity=c=4200J/kg°C

According to thermodynamics

\\ \tt\bull\rightarrowtail Q=mc\Delta T

\\ \tt\bull\rightarrowtail Q/mc=\Delta T

\\ \tt\bull\rightarrowtail \Delta T=\dfrac{78450}{0.75(4200)}

\\ \tt\bull\rightarrowtail \Delta T=24.9°C

\\ \tt\bull\rightarrowtail T_i-T_f=24.9

\\ \tt\bull\rightarrowtail T_f=100-24.9=76.1°C

Use the drop-down menus to classify each of the following as an addition, substitution, elimination, or
OLga [1]

Answer:

CH3CHO+H2O → CH3OCH3 - addition

CH,CICH CI + Zn → C2H4 + ZnCl2 - elimination

CH3CH3Br + OH – CH3CH3OH + Br - substitution

2CH2COOH >>(CH3CO)20 + H20 - condensation

Explanation:

An addition reaction is a reaction in which a specie is added across the double bond as we can see in CH3CHO+H2O → CH3OCH3.

In an elimination reaction, a small molecule is lost from a saturated compound to form the corresponding unsaturated compound as in CH,CICH CI + Zn → C2H4 + ZnCl2

In a substitution reaction, a chemical moiety replaces another in a molecule as in; CH3CH3Br + OH – CH3CH3OH + Br .

A condensation reaction is in which two molecules are joined together to form a bigger molecule as in; 2CH2COOH >>(CH3CO)20 + H20.
