Answer:

synthesis/combination

Explanation:

There are 5 main types of reactions.

combination/synthesis, decomposition, single-replacement, double-replacement, and combustion

synthesis/combination - A+B → AB

Decomposition - AB → A+B

single- replacement - A + BC → AC + B

double replacement - AB + CD → AD + CB

combustion - example - C3H8(g) + 5O2(g) → 3CO2(g) + 4H2O(g)

If you wanted to balance this

the answer would be $C + 2H_{2}$ → $CH_{4}$

a group of students wants to see how temperature affects the time it takes for spilled water to dry up in the investigation what

kirill [66]

<span>The independent variable is the one that researchers directly change. Here, the students will deliberately change the temperature, so the independent variable will be temperature in degrees. The dependent variable is the one that researchers measure as the outcome of the experiment. Here, the students will measure the time it takes until the water is gone (evaporated), so the dependent variable will be time, in units of seconds or minutes or hours.</span>

What is the osmolarity of a solution made by dissolving 0.50 mole of the strong electrolyte cacl2 in 1.0 l of solution?

valina [46]

Osmolarity=osmole of the solute/litres of the solution
ionic equation for dissociation of CaCl2 is
CaCl2--->Ca2+ +2Cl-
total osmoles for reaction are 1(Ca2+) + 2(Cl-)= 3 osmoles
therefore

0.50 moles of CaCl2 x 3 osmoles/ 1mole of CaCl2 = 1.5osmoles
osmolarity=1.5 /1.0 L=1.5 osmol/l

The enthalpy change for the reaction 2K + S + K2S using the following thermochemical reactions is mathematically given as

dn=70.7kg

<h3>What is the enthalpy change for the reaction?</h3>

Generally, the equation for the Chemical reaction is mathematically given as

2k+s----->K2S

Therefore

KS+K----->K2S

Therefore

dn=dn1+dn2

dn=32.5+38.2

dn=70.7kg

In conclusion, the enthalpy change is

dn=70.7kg
